Below we provide a schematics and list of materials to assemble a simple, robust and affordable full-metal clay extruder. It is designed from standard components to be easily build with minimal set of tools and should be compatible with most of desktop 3D printers.
Advanced Ceramic 3D Printing KIT is available on Kickstarter. In that version we implemented a number of engineering solutions to make 3D printing with different visocous materials more precise, robust and convenient than ever before.
