Massimo Moretti (the founder of Wasp) has built the largest 3D printer in the world.


“With that printer, we build houses” says Massimo, “because in the world there are many people who need a roof and have no more than a few hundred euros to get it.”


To build the Big Delta it took 3 years of research and sacrifice: “We started with 7 thousand euros in cash” says Massimo, “we financed the project by selling replicas in scale of the printer. In the end, the efforts were rewarded, building the world’s largest 3D printer gave Wasp global visibility, launching it into the world of 3D printer manufacturers.” Massimo explains that Delta 12 was designed to be simple and so it could be assembled and disassembled in about 3 hours.



“It consists of about 70 pieces, powered by solar panels and consumes less than a hair dryer.” A mega sustainable printer, therefore, from which eco-sustainable homes are born. “We call ourselves Wasp because we are inspired by the wasp potter or mason. These wasps build very resistant nests using the materials of the place, sand or earth balls that are mixed and shaped thanks to a liquid produced by the insect. We use the scraps of agriculture, fine earth, chopped straw and husk of rice that acts as an insulator. The dough is inserted into a tube and placed on the ground by an extruder, which moves according to a pre-established design. When the first layer has dried, we start with the second and so on, after 5 days the plant is solid and we can place the wooden roof.”


Technology moves fast and distractions aren’t permitted, Massimo explains “if you want to work in this sector you have to love the challenge. Every 6 months a product is old, you cannot think of doing something and live on rent, you must always look for new solutions, new materials and new fields of application.” A perfect example of this is the Delta 12, the printer was completed only 3 years ago, but next October 6, the second version will be presented, with this version being more efficient and easy to build. Massimo says “we worked hard and without stopping, also because today we can afford 4 construction engineers who work full-time on the project.”



The dream that has been pursued for a long time has become a reality, “by the end of the year we will start selling printers to make houses. Next week, I will go to the Majella national park in Abruzzo, where Pope Celestine V decided to spend a life as a hermit by giving up the papal seat. There we will build hermitages, sustainable shelters dedicated to tourists who want to rediscover the beauty of the place without impacting on nature.”


Wasp’s laboratory is the ideal place to appreciate the extraordinary potential of 3D printing. Until recently, printers produced pieces of 20 or 30 centimetres at most, but with these measures you can’t build many objects useful to man. So, Wasp developed a printer of 1 metre, then 1 of 3, to make all the products that are needed, such as furniture, theatre sets, statues, vertical hydroponic farms to grow the vegetable garden at home, taking up little space.



The most important project, in addition to Delta 12, is the “Digital Orthopaedic Laboratory”, a replicable laboratory, exportable and installable everywhere, which allows to produce customised orthopaedic devices with 3D printing, at extremely low costs. Massimo explains, “we have started a project with the University of Damascus, in Syria, where they need thousands of prosthetics. For the time being, we have sent printers, but we would like to install a workshop there and teach local staff to scan the parts of the human body that need to be replaced by prosthetics and print them. We are willing to put ourselves at the service of medicine, tell us what suits you and let’s try to develop a production process.”



Massimo is an electronic expert and before founding Wasp, he worked for 20 years in the 3D modelling sector. He says, “at one point I felt the need to do something useful, not just to survive, but to make sense.” That something built him slowly, brick by brick, thanks to the enthusiasm of a young team, composed of youngsters just out of school and graduates who had the merit of indicating a goal and the means to achieve it – 3D printing. “We would like everyone to have the opportunity to become producers without having large capital. Imagine a future where what matters is the vision and it will be enough to have fresh and original ideas to live decorously.”
