Technogym e WASP

Together with Technogym we present 3D printing in wellness

We had the opportunity to talk to the designers who work of Design Department of Technogym, the wellness giant. They explains us how large format 3D printing accelerate the company’s ability to innovate.

With yearly revenues above € 650 million in 2018, Cesena, Italy, based Technogym is one of the largest global operators in the wellness segment. Since it was founded in 1983 by Nerio Alessandri, the company has focused on key values such as environmental sustainability and innovation, which are clearly reflected in its state of the art Technogym Village headquarter. Here you will find its T-Factory and T-Research and Development Department, where over 130 engineers and designers have produced over 140 international patents and more than 93 trademarks.

The Research and Development Department plays a central role in the innovation process at Technogym, along with the Design Centre, which is responsible for the state-of-the-art product design and ergonomics. In the past few years, many of these innovations have been prototyped using a Delta WASP 4070 INDUSTRIAL 4.0 3D printer.

Conceptualizing innovation

Technogym decided to work with one of the world’s leading manufacturers of Delta architecture 3D printers and brought a 3D printer into their design department. “Our primary objective was to visualize and accurately represent our ideas, intended as the shapes of the parts we design as well as test how we are going to use these parts on our machines”.

In Technogym, he is in charge of conceptualizing technical tools and design the products that will arrive on the market. Needless to say, 3D printing has become a central part of workflow, drastically reducing errors during the product development phase and reducing lead time, especially for large size parts.

“In both the conceptualization phase and in the project assistance phase we need to be certain that what we model in CAD on a computer gives us the same answers in real physics as well. We need a component or product to convince us in real life, and not just on a monitor. At this time, this is a specific demand of the design department. Of course, the production teams are also always looking for a way to reduce the number of iterations in the production phase.

Why Technogym has chosen WASP technology

At the beginning the company was already using a small filament based system for prototyping in ABS, using a closed materials system. The choice to turn to WASP was dictated by the need to have a system that was easier and more intuitive to use, with lower maintenance costs and - in particular – that could produce very large parts without using support material that would need to be removed using environmentally toxic products.

The choice fell on the Delta WASP 4070 INDUSTRIAL 4.0, which is now located inside a modeling center with sufficient space and tools to manage the full 3D printing workflow. A single system enables to company to produce between 15 and 20 parts, measuring as much as 30 cm in height, each month. The team use it mainly for 3D printing style models or to verify shapes, ergonomics and design elements. For this, they use mainly PLA-based materials, which are ideal for concept models and do not release toxic fumes during extrusion and deposition.

Larger, faster, better

“We chose the Delta WASP 4070 INDUSTRIAL 4.0 system for a number of reasons”. “One is certainly its large print volume, which enables us to print much larger parts than an average 3D printer. We also appreciated its printing speed and the much lower cost of supported materials, which allows us to buy more material spools and conduct more tests. Since it uses an open materials system, we can also decide to change the type of filament anytime, as our needs change over time. In addition, while it may seem like a trivial issue, the ability to select a filament’s color is actually very important for us. It allows us to save the time it would take to paint the part or, if we do need to paint it in a light color, we can just print in white so that the colors can stand out without requiring a base layer of white paint. The Delta WASP 4070 INDUSTRIAL 4.0 was also very easy to install and quite affordable for a system this large. Last but not least, it ensures a very high and repeatable quality standard of all the parts we print.”

Integration and innovation

Technogym’s development center makes intensive use of a number of machines to produce its functional prototypes. The company also often turns to external providers that can deliver mock-ups and prototypes on demand. 3D printing allowed the company to accelerate this process by ensuring that a part is error free even before the final prototype is completed and the actual final parts go into production.

“It is extremely important to have this kind of ability when you work on developing innovative concepts that have never been done, or even tried, before”. “This ability to rapidly innovate has made Technogym a global and technological leader in the wellness segment. Successfully integrating large format 3D printing into our workflow is going to continue to represent a key advantage for us going forward.

Italdron revolutionizes drone production using Carbon Nylon and WASP 3D printing

The greatest value in terms of business and knowledge is formed at the crossroads of revolutionary technologies

Among the newest generations of products, drones are among those that best embody the concept of innovation. Not only for their technical characteristics, but also for the cutting-edge technologies used to develop and build them. As a manufacturing process, 3D printing is increasingly used within the drone production cycle, mainly for prototyping.

Italdron, an Italian company specializing in the design and production of innovative commercial drones, has been using 3D printing since 2014 and has further raised the bar by collaborating with WASP for the production of its latest, futuristic models. This latest application case clearly demonstrates how the right AM technology is now mature enough to ensure reliable final components and, at the same time, significantly reduce development times and costs.

Meet Italdron

Italdron was founded by three young entrepreneurs aiming to develop a service market using drones. Starting from aninnovative idea, the company has grown into the manufacturer with the highest number of Remote Piloted Aircraft (APR) authorized for flight by ENAC (the Italian National Civil Aviation Authority), as well as the first Italian manufacturer of professional drones to be licensed for "post-production flights".

Can it fly?

For its drone development and production needs, Italdron decided to turn to WASP’s 3D printing systems, integrating them within the production process . The relationship between WASP and Italdron has been going on for years, first with rapid prototyping and then gradually moving towards production of final components.

"We use WASP printers for different sectors: from production of mechanical tools, such as forklift hooks, to the creation of particular molds used to produce the drone body," explained Marco Solfrini, Italdron's design engineer. “We often work on customized vehicles. In most cases, in fact, the basic drone remains the same, but it needs to be customized to meet the customer's specific needs. WASP 3D printers are key for us given their precision and the significant printing height they can achieve”.

Italdron currently has 3 WASP printers, two Delta WASP 2040 and a latest-generation Delta WASP 2040 INDUSTRIAL 4.0 optimized for printing technical materials. The printers of the Industrial 4.0 Line can be networked and therefore managed directly from any mobile phone, tablet or laptop.

An innovative chamber system controlled up to 80 °C, with "Hot and Cold Technology" mechanical cooling, allows for optimal printing of advanced polymers and composites. A camera insidethe printer is used to monitor the print progress remotely. Thanks to these innovations, the printers can work 24 hours a day, producing both prototypes for testing and flying drone components, allowing the Italdron team to be able to evaluate their functionality and to detect any mechanical issue. In this way, the team can have tangible feedback on the project in extremely short times. The Delta WASP printers are able to print 24 hours a day because of their very robust mechanics, making them virtually indestructible.

Benefits of AM integration

"WASP 3D printing technology enabled us to speed up the production process and reduce costs," continues Solfrini. "In addition, they supported in every way. When you turn to WASP, you can count on an efficient customer support service. They help you at every stage, you can exchange ideas and develop new solutions. This relationship has greatly facilitated us in introducing this technology into our production cycle in a stable way ".Currently all the caps - which form the drone's hull - are 3D printed using Carbon Nylon filaments, to be installed on the final models. The choice of using Carbon Nylon as the main material for parts is tied toits excellent ratio between flexibility and resistance even at high temperatures: the latter, in particular, is fundamental to ensure that every Italdron drone can operate efficiently in the open air –where it is subjected to the most diverse climatic conditions.

Solfrini also emphasized how current AM technologies can provide a real added value for industrial production, and are destined to find more and more space in this area: “3D printing represents one of the key production tools of the future on an industrial level – he says. It is destined to play a more dominant role in production processes by integrating perfectly with technologies such as CNC and other machine tools. In our case it is a fundamental step: our drones, in fact, are assembled by combining pieces made of carbon, aluminum and 3D printed Carbon Nylon. This allows us to significantly reduce the weight of the vehicle, without sacrificing efficiency and robustness".

The collaboration between Italdron and WASP is not only a perfect example of "Made in Italy" innovation, but a strong demonstration of how the AM solutions offered by the Massa Lombarda company are now true technological enablers, which can help to address critical issues and improve traditional production process.

The BOWDEN is suspended, to make work faster and minimize the weight on the extruder.

Furthermore, like all WASP printers, the Delta WASP 2040 PRO contains the RESURRECTION SYSTEM, the system that automatically resumes interrupted printing in the event of accidental shutdown or sudden power failure. The FREE Z-SYSTEM allows you to restart from the height of interruption of the print.



“Your material, your dimension, our mission”

Versatility, ease of use, productivity. These are the concepts that have guided the development of WASP 3D printers since the beginning and which characterize even more clearly the new Delta WASP INDUSTRIAL Line 4.0.

It is not easy to combine versatility and ease of use, but this is the request coming from an increasingly demanding market and it is a challenge that WASP has accepted to face, ensuring on the one hand the possibility of using more and more technical materials and printing larger and larger sizes, on the other hand WASP has paid much attention to the user, introducing a series of product features that make the new printers even more user-friendly and intuitive: touch screen, on-board video tutorials, self-calibration, family feeling, remote assistance.

A novelty of the new line compared to the previous industrial line is the entry of the smallest printer, the Delta WASP 2040 INDUSTRIAL 4.0 into the family. It goes alongside with the Delta WASP 4070 INDUSTRIAL 4.0 and the Delta WASP 3MT INDUSTRIAL 4.0.

The new User interface allows a better user experience across the entire WASP product line; the Video tutorial on board guides the user as a sort of assistant coach on board of the machine; the Wifi module for remote control of the printer and for compatibility with Industry 4.0 allows you to manage the entire printing process from your computer; the Live view camera allows remote inspection of the current print and time-laps; the Multicore automatic extruder recognition is a system that recognizes which extruder is mounted on the printer and automatically makes the setting; the Auto calibration system is a function of the extrusion system chosen and installed on the printer. Finally, the new WASP machines allow a printing Via Usb, not only with Sd Card.

As for the third driving factor of the new INDUSTRIAL 4.0 line, that is productivity, the WASP printers continue to offer to the market essential characteristics like: high printing speeds, high reliability, high quality and the possibility of using technical materials. Of course, the highly appreciated rescue system of the work done, remains in all the machines: End-filament sensor, Free-Z-System(cc), Resurrection System(cc).

HOT & COLD Technology - cc

Hot & Cold Technology is the new system of active controlling the printing thermal conditions.

Thanks to an efficient way of heating by two internal heat sources, it is possible to ensure work temperatures up to 80 °C, without burdening the mechanical parts of the machine.

The innovative air cooling system allows keeping the temperatures below the critical threshold of cladding materials.

The opening scenarios are extremely interesting on the light of raising request of technical materials and application ever different. WASP takes this challenge, supporting the user in the choice of extrusion systems and offering specific solutions to meet the needs of different customers.

Spitfire System

Configurable and fast extruders by WASP

Extractable cartridge
with a simple turn of screw

The idea behind the new Spitfire System is to simply extract and replace a cartridge (consisting of nozzle, barrel and coupler) with a simple spin of screw, depending on the different printing needs and on the materials you want to print.

The New Spitfire System

The innovative WASP Spitfire System leads to a whole new generation of extruders: the modular architecture allows to mount a specific cartridge and nozzle for what’s your need. Decide what you want to print, we give you the right extruder.
Spitfire takes its name from the famous Second World War airplane. It’s an innovative system, that throught several configurations, allows to reply to the several printing needs.
It’s a guarantee of high quality and sturdy printed pieces, it can be heated up to a 350°C temperature and according to the several needs it can be assembled in 3 different sizes: 0,4; 0,7; 1,2 mm. All the exchange or configuration operations are safe and quick thanks to the Spitfire System.

The cartridge (consisting of nozzle, barrel and coupler) is the heart of the Spitfire System and gives the new WASP extrusion system maximum modularity and versatility. From now on, the extruder can be configurable, depending on the different printing needs.

Two different steel cartridges: Spitfire Core LT (cartridge with teflon) for low temperature prints, Spitfire Core HT  (cartridge without teflon) for high temperature prints. To gain long lasting extruders and minimize frictions.

Good luck Myrijam!

Top WASP DLP new WASP 3D Printer

A new approach to DLP printing

Combine the TOP DOWN PRINTER characteristics with innovative solutions such as SELF PEELING TECHNOLOGY. The DLP printer uses a projector to emit UV light. This carefully modulated light polymerizes a photosensitive resin, solidifying it. The light generates the object in layers, and results in an accurate and precisely rendered object. This Top WASP DLP printer is best for high-precision models; such as for micromechanics and jewelry.


WASP has introduced an innovative new system for removing the printed piece from the build plate that makes this process quick and safe.

Initially, a film is immersed into the photosensitive liquid. At the beginning the film is placed over the plate that moving in coordination with the projection creates an high definition object. Due to the flexible film, each layer is easily detached from the film as the print continues, contrary to the complicated process of detachement of the other printers. The printer includes a gas filtration system for the resins’ gases.


WASP Free Zed System

The Free Zed System is basically a recovery system for a printing that for some reasons, has been interrupted and it was not possible to use “ Resurrection“ to recover it. Or, after the Resurrection, we notice that the item is not well done and we decide to re print starting from a clear point. In short it allows to print a file starting from a precise height of the model to be printed – height previously selected.

How does it work?

The process should be very simple and intuitive. Selecting the Free Zed System from the menu, you are requested to mention a certain height (Z) in mm,  this will be the starting height. After setting up the desired height, the menu goes automatically to the visualization of the files inside the SD card, so that you can choose the file to print. The selected file will be scanned  and performed in all commands (temperature, level, extrusion, ventilation, etc…) but the movements - so the printer will be still but the SD file reading indicator ( on the display) will go on. When the set height is reached, the printer will start moving according to the data related to the Z chosen height. That means that, if on the printing plate there is a model partially printed, taking note of its height, it will be possible to go on printing even without resurrection data.

Top WASP DLP - The affordability and convenience of top side DLP projection

Top WASP DLP is here: the affordability and convenience of top side DLP projection combined with bottom side projection

Top WASP DLP is a new technological solution for DLP 3D printing. It marks a revolutionary step forward by combining the advantages in terms of convenience and cleanliness of top side light projection with the high precision of bottom projection. As is now its trademark, WASP presents this innovation by releasing it into the public domain for non-commercial use.

Technical description

WASP began working at this project three years ago, running into several problems that had slowed down its progresses. A few months ago, as is often the case, an episode inspired the solution: the image of a film immersed in a liquid opened up the WASP designers’ minds.

In the Top WASP DLP the image coming from a high definition projector is directed toward a film that is immersed, on its lower side, in a photosensitive liquid. The print plate is initially laid onto the film and - moving progressively away from it - determines the layered growth of the high definition 3D print.

This mechanism solves the issue of the piece’s detachment from the projection plane, with up to 100% print success rates. Once the operation is complete, a special, watertight lid closes the vat (which can be replaced even during the printing process), thus reducing cleaning requirements and related issues.

Project Description

A high definition projector that projects a 9 cm wide image can reach a precision of 0.08 mm. Building parts with such accuracy is the dream of any technical designer but a good quality projector and resin are not enough. This is the premise that the TOP DLP project built upon. The image can be projected both from the top and the bottom: projecting it from the top on a plate that gradually lowers enable simple and affordable prints.

The question remains on why many 3D printer manufacturers continued to project light from the bottom. The answer is on Wikipedia, under “capillary action”.

Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper, in some non-porous materials such as liquefied carbon fiber, or in a cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces … in short the capillary action is due to the pressure of cohesion and adhesion which cause the liquid to work against gravity.


The behavior of fluids on a geometrically complex part generates errors in the shaping of the object when light is projected from the top side. The error is acceptable for amateur level approaches but not in the professional arena, where DLP precision needs to be fully exploited. This is the reason why all manufacturers have been focusing on bottom projections. The image is projected on the bottom of a transparent container after this has been made anti-adherent. The print plate is laid at the bottom and slowly raised, as the part “grows”.

WASP’s old DLP

vecchia DLP WASP

In truth, even this apparently simple solution is such only at first sight. An anti-adhesive surface is necessary, and it must coincide with the bottom of the resin container. The anti-adhesive treatment can be obtained by applying a layer of silicon on the bottom of the vat.

Normally DLP and SLA manufacturers supply replacement vats or silicon and it is the user’s responsibility to change the container and replace the silicon in the printer. This makes the system more complicated to use as the vat needs to be emptied and refilled, removed and cleaned. This means that the details relative to the vat’s replacement determine the printer’s end quality.

The part’s adhesion to the silicon layer is also an issue. In spite of the silicon’s anti-adherence properties, the part tends to remain attached due to the suction effect. With use the vat become more opaque and consumed, thus attaching to the print and causing a higher percentage of print failures, as the print attaches to the projection plane and not to the print plate. Low quality 3D printers can have failure rates as high as 50%.

The Evolution

The solution first developed by WASP three years ago was to use a teflon film instead of silicon, but this did not prove fully efficient. The film wrinkled up and ripped with use, the liquid oozed out ruining the 3D pritner. The difficulty in building a simple, functional and safe vat stopped the project, until the event from a few months back that we have described earlier, that is the image of a film immersed in a liquid only from its lower side. This allowed us to reimagine and design the TOP DLP in order to combine the advantages of affordability and cleanliness of top side projection and the precision of bottom side light projection.

At last, after solving the issues of the part’s detachment from the print plane, and those of vat cleanliness, WASP added to its new 3D printer a system to filter out the fumes, thus eliminating the unpleasant odor that lingers around photo-polymerizing 3D printers.

This new product, that will be released in the next months, aims straight for the top of the quality/price ratio and it is exactly for this reason that WASP decided to name it Top WASP DLP.

Top WASP DLP will be shawn in preview during the Rome Maker Faire – October 16, 17, 18.

WASP Top DLP - pezzi multipli9 pieces made in 15 minutes with Top WASP DLP


3 years ago WASP brought his DLP at Rome Maker Faire. The main problem of this system has always been the cohesion and so the detachment of the piece from the projection surface.

Most of the producers use silicone rubbers between the printed piece and the surface to solve this problem. Some months ago it was launched a DLP which uses oxygen instead of silicone. The research is focused on a smart and cheap process to detach pieces from the printing surface.

For WASP the project was physically on hold but still going on in our mind, until two months ago, when we had an epiphany.
We created a new approach, a new way to print. In these two months the project improved to become more and more precise. And now we can say it, we have Top WASP DLP.

There will be an official launch very soon, for now here you have the printing tests in chronological progression!

Delta WASP 2040 become TURBO


While we were projecting and building the BigDelta printer, we bumped in a huge problem that we never met before: the control board (Arduino Mega) didn’t afford the amount of data that are necessary to move the motor’s axes.

It seems impossible that a processor which controls 16 logical states, with a calculation speed of 16 millions cycles per second, for a total of 256 millions operations, can’t control the mechanical part.

Paying more attention, however, a Delta printer executes 200 square roots per millimeter for each axe (and we have three axes, plus the extruder). We noticed that Delta configuration needs a huge amount of data to work, and it was for this reason that our BigDelta, several meters tall, was printing jerky and the display update was late.

We were blocked in this situation and we needed to push hour research out of open source world, to sail in a see where nobody did.

In fact in open source you can’t find more powerful boards: who developed one doesn’t share it. Many people make full use of shared knowledge but very few of them share innovation.

WASP incudes Dennis Patella between his coworkers. Dennis is a real innovator, he disassembled Marlin program and ricomposed it for our purpose. The mission seemed to be impossible, just like the ones we like more: a RISC processor with 32 bit and 82 millions operations per second, for a total amount of 2624 millions operations per second can do what ten old processors do.

The work is hard: this processors need a three volt source to avoid overheating and energy wastefullness. So motor’s drivers need to be resized just like the mosfet of peripheral’s control and the marks of analogical-digital “comparatori”.

When play becomes hard a Wasper neves steps back, on the contrary, in these situations he shows the best part of him. Therefore Dennis, Roberto and Massimo redesigned the board and assembled it on a Delta 20 40.

As it happened for Resurrection System, we tried to solve some Big Delta’s issues and we found new solutions to emprove our small size solid printers. DeltaWASP 20 40, strong and resistant as it is, was fitting the new board’s calculation power, leaving everybody astonished.

What was happening was a real fight between electronics and mechanical: speed was increasing and acceleration was growing of 150%, 200%, 300%, 400%, 500%... from the 3000 mm/s² we were used to, to 5000, 10,000, 20,000  mm/s².

DeltaWASP 20 40 manages several millions data per seconds, executing them completely. It seemed like it was going to fly.

The green rubber bands which distinguish our suspended extruder (Creative Commons protected) and the whole Delta’s features make this kind of results possible. Movement speed up to 1000 mm/s and acceleration up to 20,000 mm/s².

The enthusiasm was at the top when we understood we were in front of one of the fastest printer in the world. pheraps the fastest.

At the 3D Print Hub in Milano, WASP will present the DeltaWASP 20 40 Turbo version. The printer was already one of the fastest in the market and now is the first that reaches 1000 mm/s.
The group, that is working on the development on the BigDelta (a tall robot 3D printer, designed in order to build houses with ecological and 0km building materials) faced the necessity of having a more powerful electronic board and processor in order to move the arms of the printer at high speed and with a better fluidity of movements. From this need, start the new project of WASP: the modification of the firmware that command the printer (Marlin), a re-designed pcb board with a 32 bit RISC processor able to do 82 million operation per second.
“In the open source world we didn't find more powerful boards: all firmware are for Arduino Mega. This has forced us to take a great work of 'discovery and development' that we share in open source. We know the valuable knowledge that we have been donated by the community until now” says Massimo Moretti, WASP founder.
The Waspers have tried this powerful board on one DeltaWASP 20 40. The result was incredible: with 250-300 mm/s of travel speed, with the implementation Turbo the speed can grow up to 1000 mm/s. Thanks to the characteristic of the DeltaWASP 20 40, the precision remain the same.
The discoveries in WASP are almost monthly, the group in fact re-invest into research a big amount of the gains from the sale of 3D printers. An Italian company that contributes to the sharing of the knowledge and to the diffusion of instruments, with the intent to allow , through the 3D printing , to initiate a real production.
Meanwhile, the invitation is for Milan, 5, 6, 7 March, to see one of the fastest FFF printer in the world, pheraps the fastest.

WASP Suspended Bowden

At  Maker Faire 2013 we presented our innovation on the Bounden of Family line. Well the Bounden is relieved.!!

What does it mean? It means the choice of  downloading the inertia on the hanging rubber-bands, improving like that the printing speed and quality.

Resurrection System, a 3D printing revolution


The will to build houses has made necessary the “Resurrection” birth.

An evolution of the function “stop and save”. The need to stop or interrupt the wall printing and to get it back the day after at the same point where it was left,  has been the motivation to create this new implementation.


Dennis Patella, a real maker and our collaborator, has found how to solve the firmware problem for the improvement of the function Stop & Save.

The reasoning is quite simple: the extruding data are backed up in a SD card, and just from  the same data, the printing process starts again when turned on. This system  perfectly fits Delta printers because the Delta setscrew ( limit switch) is on the top. On the contrary, in the other common 3D printers it is at the left bottom, and like this the extruder “going home” could hit the object. The system saves the data in file called “resurrection.g”.

We have implemented this function for the traditional printers too. It’s important in this case, to make the “home” of x y and not of z.

What happens in case of black out in the factory? Resurrection System is the solution to this problem

An emergency battery could have been a solution, having like this a prompt and automatic re-start immediately after the black-out. We have interrupted the track to the “Arduino” with 12 volt and have added a diode and a 10.000 µF-condenser (little battery). We have reached this measure after a long series of attempts, nobody knew in advance how long it would take to perform this procedure. Dennis has worked on the transfer-speed  and on the SD card writing a lot, and finally has made the sudden back-up possible


How does it work?

The system is composed by a voltage divider on the ’Arduino entrance; it reads the voltage present in the divider itself and gives a bar code; so , when the voltage goes under a certain level – the Arduino carries out the Stop & Save function.

In case of unplug, the Arduino would try its Stop & Save function but the machine engines, absorbing a lot of power, would prevent to fulfill it. On the contrary, if we use a diode after the microprocessor power source, we have stored the necessary power to fulfill the back-up.


In case the voltage goes suddenly to zero, the engines can use the power stored in the condenser  protected by the diode, a valve blocks the power transfer in the opposite direction.. So, the power in the little battery is enough  to keep the Arduino alive  for the time necessary to make the back-up. This function is incredibly effective and useful. The applications are many. It could save all those printings, some very long too,  that have been lost till now. Nothing similar had never been done before. Born from the need to print Houses, Resurrection has been implemented on each of our Printers, not only on  BigDelta.

Creative Commons Licence

We consider important to declare Resurrection as being protected by Creative Commons, it means that anybody can repeat  it in his own record: we make it disposal for any Maker who wants to put it in his own machine. Moreover we share the firmware with those who have  WASP models without this, now,  standard function.

We claim this technological innovation as being a useful project,  characterized by a micro-processor that, as soon as supplied, stocks  the necessary little quantity of power necessary to save the extruder data, in case of no power source. The microprocessor reads the supply voltage and starts the back-up sub-routine in case of supply lack..

Resurrection is very interesting, it is a real turning point in the printing background – so we are sure it will tease big institutions of this sector. There would be the requirements for a use-patent but WASP is in favor of the know-how-sharing.  We trust on unwritten but world-wide shared Makers rules . The approach which better corresponds to our vision is  Creative Commons, because it foresees the publication of assimilated knowledge reducing like that the exploitation from a commercial point of view.

We would really appreciate if, in case of Creative Commons rule violation, the  community protected our contribution.

3D printed mold

Can you make molds with a 3d printer?

The opportunities and partnerships in 3d printing are always rising. 

Today we introduce Tondo Garage, a garage situated in Ravenna, born from the passion of Giovanni Gallo and Luigi Tondo, ex pilot and expert of motorcycles. In 2011 they started a new project: a Garage where to design and make special motorcycles on demand. Four months ago the Tondo Garage Team asked us to explore together the opportunity to create 3d printed tanks.

Instead of printing tanks, we opted to make a model from which to generate a resin mold, in order to start a real industrial production. The process is linear: you need to scan the motorcycle and then you have to design the model to print. 

3d printed mold for motorcycle fuel tank with Tondo Garage

Why choose 3d printing?

3D Printing gives the opportunity to create a starter model with less time and a cheaper cost, compared to sheet metal prototypes. From here it can start a carbon fiber,or more valuable materials, serial production.

The precision and the speed of printing allow us to really enter in the productive process of a company and to make easier the creation of a project with special characteristics like a customizable product. 

The experts of Tondo Garage are experimenters and enthusiasts: they break new ground to get close to their clients’ requests, keeping an artiginal attitude in their work.

This mold was printed with the Delta WASP 60100 that permits big size prints.
