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 usableThe 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 maturityB-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
Okay guys, the project will be canceled. Even with the 30mm Screw the results have not been satisfying. The extruded volume was too low and I had a lot of problems with molten pellets stucked and baked on the screw. So I don't want to invest no more effort. Instead I will go on with another project and a 'real' extrusion screw. So stay tuned
The B1 sample is finished. The wiper motor had an overheat defect, therefore a new 250W motor is used. Wich, suprisingly, costs the same. Because of the new motor dimesions the hole machine design needs to be changed, but testings have been promising so far.
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
