The goal of the project is to develop an cost effective Desktop Extruder which is capable of extruding filament, yarn and small beamsScope of the Project: - Desktop machine with housing - 300€ production cost max. - Extrusion Rate 0,5 - 2kg/h - Tolerance +/-0,1mm - Extrusion of standard materials like ABS, PLA etc. - Flakes and Pellets usable The project management is, like usually, done via MIRO:https://miro.com/app/board/o9J_km9R-tU=/ current Status: A-Sample: [finished ]f unctional prototypes, usually with limited scope of service and low degree of maturity B-Sample: [on going] basic prototypes with full scope of service and a high level of maturity. They may be created using pilot tools. C-Sample: [not started yet] ully functional sample manufactured with series production tools
Took a few CAD Sessions but I came up with an usable model. (without housing for the first step) Also began with the mechanical assembly. The Extruder Pipe with flange is ready and I am temporary working on the sheet elements.
Finished all the testings with the A-Sample. Yarn, Filament and smaller beams can be extruded. For further testings and increased Quality of the extrudes materials, a better mechanical and electrical construction is needed. So lets move on to the B-Version.
The functional Prototype works ! The mechanical construction and the wiring a really poor at the moment. But even this low level machine gives acceptable results. Next step will be some testing if a speed control is needed and if a Arduino 'Motheroboard' is used instead of single controller
