Recycle plastic into 3D printer filament at home
Description
trying to reupload, as my previous upload is only visible by me... Here is my attempt at recycling plastic scrap into usable 3D printer filament. The process is intended to be cheap and home-scaled (hum, rather garage-scaled !). It is based around a cheap DIY filament extruder (or extrusion line), that we can feed with plastic granules made with the help of an electric hand plane and a coffee grinder. The electronic part relays on an Arduino pro micro and some Arduino compatibles modules. With that process, some PP and ABS plastic collected from old household appliances have been successfully converted into various usable items (see pictures for a sample). The diameter of the produced filament is regulated by a PID loop driving the extruder motor's PWM using a pixel array sensor as input. But for now the produced filament is not very accurate and needs to be post-processed in order to be printable. If you feel like interested by the process, let's see what is provided here : * STL and FCStd __3D model files__ for 3D printed parts * A fully messy and commented __Arduino source code__ of my build * A __Complete Guide__ (34pages) of the whole process as a pdf file
