ETH Zurich researchers have created an innovative construction robot that shoots clay to build structures, ditching 3D printer resin entirely. This fast robotic printing process for earth-based materials, also known as impact printing, basically has a robot shooting material from above, gradually building a wall.
The parts bond together on impact, and minimal additives are required. Unlike 3D printers that use concrete, this process doesn’t require any pauses during which the material can solidify. A recent test used a mixture of excavated materials, silt, and clay, shot downwards at speed of up to 32.8-feet-per-second.
- Faster and More Efficient: Creality K1C 3d printer, equips 600mm/s printing speed and 20000mm/s² acceleration, it is12 times faster than the other...
- Convenient Operation: Creality K1C is well assembled and tested before shipment. After unboxing, it is ready for plug and play. The boot-up guide is...
- Clog-free Direct Extruder: It can print carbon fiber filament and many kinds of filament. The K1C 3d printer equips a clog-free direct extruder...
In parallel, we are developing a digital design and construction strategy for realizing these structures utilizing state-of-the-art methods in computational design and sensing to enable a breakthrough at the full building scale,” said the researchers.
