W.A.S.P’s DELTA 3D Printer

What a fab organisation – WASP is focused on improving the housing conditions of the world through the benefits brought about by various 3D printing. They have developed machines that extrude forms using a variety of materials – ceramic, clay and straw fibre, and plastic (the fundamental underlying principle is that the house builder machine can extrude with any local materials it finds!).

In their video Mission Statement it is clear that their house printing clay extruder is at the forefront of their plan to solve the world’s housing shortage. Interestingly, they incorporate seeds into their architectural substrates in order that the roots that grow into the damp soft material will result in a stronger material once dry (mirroring what I also found with my early Substrate experiments).

Their DELTA machine is a behemoth of a 3D printer but the principles remain the same – a computer-controlled XY-axis extrusion head, motorised incremental Z-axis control, a pneumatic substrate syringe, and a CAD design.

Creating clay houses in which to live has been the company’s mission from the very beginning, even inspiring its name (World’s Advanced Saving Project). It has evolved over the years, providing invaluable information to improve the smaller commercial delta 3D printers the company sells to finance it.

Although other companies have already developed large size cartesian 3D printers capable of building entire multiple storey houses, WASP’s goal is to develop a system that can 3D print in any situation, even in extreme conditions, such as those found in some parts of central Africa.
