3D Print Coral Reef

For sure one of the most interesting topic of our additive manufacturing world.
3D print Coral reef seems a really effective approach to use 3d printing and help the natural coral ecosystem repopulation.

Here we are at the European Research Project 3DPARE, where we were involved with Delta WASP 3MT CONCRETE thanks to Gianluca Pugliese from LowPoly official distributor of WASP in Spain and a certain one of the most expert in the additive manufacturing field from our community.

How to 3D print coral reef:

For 3d print coral reef you need for sure a 3d file like .stl file and the correct slicing: the project we show chose concrete and a sinuous structure. For that reason, they experiment with sand for support during the printing and manual filling.

There other similar application where is used clay instead of concrete (and we love it a lot) and also an object that uses the 3d printed infill like natural hollows. It is possible to print the object on one side and then turn up the piece to have horizontal holes.

WASP printer prints clay the same, but to finish the process you need also an oven.

Geopolymers is for sure another not much-explored way we will reach. Better way up to the scientist, is that research isn't it?

 

3D printed coral could help endangered reefs

Researchers had immersed different shapes of object to understand during the years which one is better in terms of attraction and growth of flora and fauna in each group. At the end they will choose the best and adequate shapes and material to help endangered reefs.

    CONCRETE BEAM CREATED WITH 3D PRINTING

    3D Printed Concreate

    THE FIRST MODULAR REINFORCED CONCRETE BEAM CREATED WITH 3D PRINTING

    WASP was born with the dream of printing houses with 100% natural materials, but wisdom teaches that extremism is never a good thing. While trying to find a way to print houses with natural materials and at zero km, there is an urge to plunge into the routine and make a contribution now. And this is when WASP project begins its challenge with materials taboos, such as Co2 generators. Concrete is bad for the planet. A ton of cement generates a ton of Co2, but with 3D printing you can cut down more than 50% of pollution. These are mind-boggling numbers, which can be reached only because we can create programmed infills, Otherwise, with the normal techniques it would be unthinkable to create hollow systems. A WASP printer was sent to an Italian Institute of excellence where concrete mortars are studied. Domenico Asprone and some friends of the University Federico II of Naples started using a 4 meters BIGDELTA WASP. And the machine has not been kept in the parking.

    With this mega printer, WASP researchers have developed a system to produce concrete elements that can be assembled with steel bars and beams or can compose pillars in reinforced concrete. The research is being carried on at the CeSMA service centre (Advanced methodological Services Centre) of the University of Naples and it involves the Stress Consortium (the high-tech district of the Campania region on sustainable buildings) and the University of Pavia.

    As Domenico Asprone stated to the Ansa agency '' this new technology promises to streamline the forms and save material, thus lightening the reinforced concrete elements and reducing costs and environmental impacts. The possibility to obtain complex shapes then, paves the way to new uses of reinforced concrete beyond the conventional ones, with aesthetic properties and design. ''

    "The 3D printing- Marco Iuorio from Stress Consortium explains-allows you to create curved, hollow elements, or with special features that would normally require complicated wooden shapes (moulds) for fresh concrete, with a considerable cost increase".

    In the laboratories of the Department of engineering Structures and architecture, a test will be performed on the first beam, of about 3 meters long. The test will also check the mechanical performance of the new reinforced concrete elements. Moreover, the experiments of new assembly systems based on the prestressing technology will continue.

    Thanks to these new technologies we could say we are moving towards the House of the future. But why should we set some limits? One day we will also be able to print more complex structures, such as bridges. And there will be broader space for creativity.

    BigDelta WASP experiments new materials in Barcelona

    An intense week full of print tests at Constumat event, hosted by IAAC (Institute for Advanced Architecture of Catalonia) in Barcelona was the circumstance to experiment different materials and mixtures with our BigDelta.

    The continuous research on materials is the key for the uninterrupted implementation and improvement of our printers: a modified version of our cochlea extruder with rotating nozzle permits a better deposition of fibers, which can be present in an higher percentage in the mixture.

    Thanks to the new version of the extruder we printed a chair made of wood paste, by using a mixture made of liquid glue, flour and sawdust.

    A local craftman provided us with a recycled material fiber that he uses in his works, we printed it with a concrete paste.

    Another live experimentation was the one we made with mushrooms mycelium: we extruded a support to make it grow. Mycelium is the focus of many green building projects, this 100% compostable material is an ecceptional insulating and it is more resistant than concrete. It can be used, just like in our case, to reinforce the structure, in which it forks.

    We thank IAAC for having involved us and all the people who collaborated with us in these days, during the live exsperimentation and the operative research.

    Gràcies!


    With the new extruder WASP can truly realize the house dream

    Animals teach us that every wasted energy must be recover getting food, getting what they need. The innovation of our research toward 12 meters tall WASP BigDelta, toward the printer for clay houses, is inspired to this concept. In the end the solution we were loking for was in our name, in nature, in potter wasp.

    Compared with the one we presented at Maker Faire in Rome on 2014, the distinctive and decisive element that characterizes the evolution of the one we have now is the new extruder. Movements control is crucial in 3D print, but it was very difficult with the old peristaltic pump-extruder. That’s why we completely redesigned adoting a cochlea concept. Now we have an extruder wich can even manage retraction, so it can stop working and pull extruded material back.

    In a few words, we moved from a continuous extrusion to a precise flow control,and to the chance of stopping the work and resume it with a micrometric precision. The new extruder can be assembled and disassembled very quickly, it cleans by itself, it needs a very low energy amount and it has a costant control at all the speed levels. Moreover, thanks to rotating nozzle, the material isn’t only extruded but also mixed in his way out. In this was layers are more cohesive and tenacious.

    If we look back and think to the way we walked through, the biggest obstacle for the twelve meters tall printer was the extruder. We had to understand not only how to extrude, but also how to refill materials and keep the system operative. It has been a continuous research and we tried many solutions. In the end we went back to the potter wasp, which takes material by her self when she finishes it. With the same system, our printer reduces at minum the amount of energy that it needs. Now we can easily print and do other things instead of refilling material. The save of energy is evident: to push the clay in the tubes it takes several kilowatt, to let clay fall in a controlled way it takes just a few tens of watt.

    All these devices are contained in our extruder and characterize the printer. These technical solutions are ready to be repeated in a bigger scale. Now we can say that we created a printer which produces big objects without any waste of energy, and we think this can be a real revolution, not just for the constuction field. We can print not only houses but also animal refuges, pensile gardens. The approach has completely changed, and the main foucs is energy.

     

     

    What others advantages will grow out of the rotating extruder? We still don’t know. We needed this kind of system to mix material and keep clean the nozzle. From that need we started to arrive at the final result. The force of this technology compared to the ones we tried is that is a continuous supply system, it feeds itself while the printer is working.

    Who saw in these years the various technological passages of the machine can understand the greatness of this revolution. Even the only extruder could have important results in the building field. It’s a sort of controlled operation cement mixer. More applications are, as usual, to be discovered yet. In our world it often happens the passage from one kind of technology to another. There is no need to be dogmatic, humilty is very usefull to understand what is the right solution, we must be ready to change our path everyday, or even throw away what we’ve done.

    Many people ask us when we’re going to built the first house. Now we have all the conditions and premises to the crucial jump. We think we have played our role, we projected (and in a few time we will build) a printer to erect houses. There are the right conditions. Then, other factors will enter the game, we need other subjects: institutions, municipalities, territories. Sardinia Research (Sardegna Ricerche, is a local institution) and Iglesias municipality are interested in the project. For sure it will be a team work. Others équipes will print houses, we will keep our research to emprove the system. This is our extraordinary, charming and challenging “conviction”.
