ADV MAT PROCESSES & DIE DESIGN
Filament Production from Recycled Bottles for 3d printer
Followings are the steps of working mechanism:
-
PET bottle is forced downward as shown.
-
Paper cutter blade is placed in such position that it cuts the bottle into stripes of about 5-7mm.
-
The long strip is moved through a heater and extruder of definite hole to form a cylindrical extrusion.
-
The extruded plastic is rolled on the pulley.
-
Arduino and motor driver are used to maintain temperature and motion of the pulley and thus the filament.
-
The extracted roll can be used as filament for 3D printer.
