A 3D printed installation with bioplastics

It is confirmed once again that the WASP HUB network is a winner player for the realization of large format works.

WASP Hub Macerata, Design For Craft and the WASP HUB network have in fact printed 360 elements in wood-filled bioplastic with the 3D printer WASP 3MT HDP.

WASP 3MT HDP is the perfect 3D printer for the digital manufacture of installations and furnishings. Thanks to the pellet technology, therefore and the possibility of printing directly the granule directly, the production costs are lower, and the productivity is higher.

“We designed and produced a small series of support for smartphones that also work as a passive loudspeaker for the Grottini Retail Environments Company. To realize them it was used the same geometry used in the design of the walls of their Agorà exhibition space (at the Euroshop in Düsseldorf) and the same material. The aim is to offer visitors a complete and totally personalized experience”
WASP Hub Macerata - Design For Craft

3d printed installation

The Grottini Company booth at the Euroshop, called Agorà, was designed by an international and multidisciplinary team with the aim of creating a rich and engaging experience, that can involve all the senses, thanks to the co-presence of multimedia technologies who work in a coordinated way with design.

Design for Craft (WASP Hub Macerata) supplied the panels that make up the perimeter walls of the space, realizing them through digital additive manufacturing powered by PLA pellets.

The design of these elements is the result of a biomimetic design attitude, born from the observation of the "endoskeleton" present in some plants, such as cacti, for example. The fibrous members of the interior of a cactus, in fact, were acquired using a 3D scanner, through a reverse-engineering process, it was translated into an algorithm that describes its morphological genesis using the Grasshopper parametric modeling software.

In this way the software developed different designs by simply varying some of the algorithm inputs: in that way it was possible to design 6 variants generated by the same original model to obtain a variability of design on the entire surface to be managed, about 190 square meters.

The production of the 360 panels took place thanks to a large 3D printer: WASP 3MT HDP.

The material used is a PLA and wood powder bioplastic; these, besides having characteristics of biodegradability, have given the produced elements a natural-looking finish reminiscent of natural wood.

The final appearance of the walls is particularly scenographic: the variability along the vertical direction it’s a sort of shrinking wave, the visual transparency between inside and outside gives dynamism to the entire surface.

Large scale 3D printer

Stampante 3d

WASP 3MT HDP is the 3D printer designed for massive prints. With the technology High Definition Pellet, you can print Pellet material fastly and precisely. Pellet granules are 10x cheaper than filaments and they reduce the printing time. In plus, you can print 24/7 thanks to the Continuous Feeding System.

Digital Fabrication and Art in dialogue by WASP Hub Venice

Digital fabrication processes, 3D printing, bioplastic and the union between technology and craftsmanship are the elements that make possible new processes of creation and artwork reproduction, in an absolutely detailed, rapid and economic way.

Fablab Venice was recently involved in the creation of a large-format artworks, in collaboration with the London art-gallery SoShiro and starting from a scale sketch by the artist Arlene Wandera.

The work, with a strong symbolic meaning, represents a female figure wearing a large metal necklace, a symbolic representation of the typical jewels of the pokot people. In fact, the artist's work focuses on the issues of everyday life and female empowerment.

Manufacturing follows an articulated process, which explores the great potential of digital fabrication in the artistic field: the 20 cm high sketch, created by hand by Wandera, was scanned obtaining a detailed digital model; this was divided into portions and optimized for 3D printing and subsequent assembly.
For the printing phase, Fablab Venezia used Delta WASP 4070 INDUSTRIAL 4.0, Delta WASP 60100 and Delta WASP 3MT with filament extruder, the material used is PLA.

The assembly phase was followed by the post-production and finishing of the sculpture, using special resins and plaster, the process ended with the roller and brush painting.
For the production of the necklace structure, milling, laser cutting, and hot bending techniques were used.

The result is a powerful work, an exact reproduction of the scale model; the English gallery, at its first experience with digital fabrication, was pleasantly impressed by the intrinsic potential of a technology, 3D printing, which is increasingly venturing towards new applications, beyond prototyping in the manufacturing field.

3D ABS sculpture

Huge 3D printed ABS sculpture

The world of 3D printers is now included in the majority of production processes thanks to technological stability and the improvement of technical materials such as ABS. The fields of applications are endless: medical, construction, production, ceramics up to the world of sculpture.
In this case WASP realized a 4 meter by 2.5 meter sculpture in ABS with the Delta WASP 3MT industrial 4.0 3D printer.

3D Scanning

We started with a small sculpture of a stylized bull, which was later to be replicated on a monumental scale.
Let's start with a 3D scan

3D scanning with Artec Eva

In this project we used the Artec Eva 3D scanner, a tool for acquiring objects using structured light. It is a process in which a luminous pattern is projected onto the surface of the piece that will determine the digital reconstruction of the subject.

The file obtained was resized by scaling it from 20cm to 400cm. To 3D print objects of this size you need a large 3D printer and a quick printing process.

Pellet extruder for ABS

The solution is the Delta WASP 3MT Industrial 4.0 3D printer, which thanks to its size is able to make objects up to 1 meter of print even in ABS. Furthermore, the possibility of printing with the pellet extruder, allows the use of nozzles with a diameter up to 3mm, and therefore print objects with a layer height 10 times higher than normal. .

This means that normally by printing with the classic filament and using nozzles with a diameter of 0.4mm, a 10-hour piece with the pellet extruder can be made in just 1 hour.

On the other hand, the possibility of reducing printing times by raising the layer height value inevitably creates a coarser surface, characterized by the various printing layers. For many in the design world it also becomes an aesthetic and design feature such as the Iride or the Bike Chair.

Before and after ABS post production

But we will see in the following chapters how to eliminate the various layers during post production. .

Continuous printing in ABS with Delta WASP 3MT Industrial 4.0

Once scaled the sculpture, through Meshmixer software it was divided into several parts to optimize the fabrication times. Four printers worked in sync producing 2 pieces per printer per day.

3d printed ABS parts assembling

Thanks to the technical improvements we implemented on the Delta WASP 3MT industrial 4.0 3D printer, in 3 days the 25 pieces in ABS were ready to be assembled.

The 50kg pellet tank with auto power supply and the material end sensor allowed the printers to work 24 hours a day without ever stopping. The system essentially recognizes when the pellet is almost finished inside the extruder and automatically feeds itself.

3D sculpture: ABS is an excellent material for post production

As the printers finished producing the missing pieces, two WASP operators began assembling the parts already made.

The choice of the material to be printed is very important, especially in terms of end use:
should it be placed outdoors?
will it be subjected to heat sources?
will it have to withstand impacts or compressions?

In addition, the choice must also be made considering whether the finished product must be sanded, painted or otherwise subject to post-production processes .

3D printed sculpture 4m x 2.5m

The 3D printed sculpture in question had to be smooth, painted and placed in a garden, so the choice of ABS was the perfect solution for this application.

3D sculpture and post production: ABS Juice

A mixture of acetone and ABS granules (you can also use waste or ABS supports), was used as a glue between the various printed parts. . 

ABS parts fixing

The diluted ABS in acetone allows a perfect adhesion / fusion between the various sections making the sculpture a single solid object, resistant to heat and weathering. .
Moreover, if used as a filler, the mixture is perfect to even out the entire surface

Finsihing with ABS Juice

With a spatula, gloves and mask, getting to the smooth piece is a snap.
Finally sandpaper in hand and the sculpture is ready ;-)

WASP Hortus Sistema di Coltivazione Verticale Idroponica

Il progetto WASPhortus si propone di esprimere le potenzialità della stampa 3d applicate al campo della coltivazione idroponica per generare orti verticali adatti alla produzione di ortaggi in ambiente domestico.

Ogni torre è composta da quattro moduli interamente stampati in 3d con Delta WASP 3MT. I moduli sono facilmente assemblabili e lavabili ed accolgono complessivamente 64 piante da orto. La coltivazione si basa sui principi della coltura idroponica, in cui l’apparato radicale degli ortaggi viene irrorato di acqua, arricchita con sostanze nutritive compatibilmente con i cicli vegetativi.

L’unicità nella forma di ogni singolo modulo, permessa dalla tecnologia di stampa 3d, consente la corretta irrigazione di tutte le colture impiantate e il continuo riutilizzo di acqua all’interno dell’invaso centrale. Il modulo di base viene, infine, rivestito esternamente da una sagoma circolare, interamente stampata in 3d attraverso miscele di calce-cemento e caratterizzata da profili superficiali curvilinei integrati alla fase di estrusione.
