3D Printing With Clay, Thanks to Custom Extruder
Originally published on hackaday.com by Donald Papp on 22 August 2023
The challenges of 3D printing with clay are being addressed through innovative solutions. Davidsfeir has developed an updated clay extruder suitable for Ender 3 printers. This extruder, originally designed for delta printers, is adapted to work with the Ender 3, enhancing accessibility.
The extruder receives lightly pressurized clay through a clear tube. Air is released at the top (motor side), while an auger inside homogenizes the clay and pushes it out through the nozzle. What makes this paste extruder unique is its ability to handle clay, which can’t be stored on spools. The clay is fed into the extruder via a hose with the assistance of air pressure. The auger then guides the clay through the nozzle while allowing air bubbles to escape from the top of the assembly.
Davidsfeir’s design is influenced by clay-printing pioneers Piotr Waśniowski and Jonathan Keep. Piotr Waśniowski developed a de-airing clay extruder, and Jonathan Keep extensively documented clay 3D printing in a freely-available PDF. PiShop might not be able to print with clay yet however we do offer a range of resin and FDM printers
In the realm of clay 3D printing, numerous areas are open to innovation. Unique outcomes have been achieved, such as intriguing patterns generated by placing a subwoofer under a print bed.
