Recycling 3D Prints and Waste Plastic into Filament (PET & PLA)

Transform your unwanted 3D prints and household plastics into eco-friendly 3D printer filament! 🌱 More Extrusion Info: Filabot Recycling Lineup: Shredii: Description: Welcome to Part 2 of Dr. D-Flo’s plastic extrusion series. If you haven’t already, be sure to check out Part 1 (), where a variety of NEW materials are extruded into 3D printer filament. In this video, we will recycle unwanted 3D prints and plastic items found around the house into filament. The first step in this process is to grind up old parts and empty containers with a shredder/granulator. You’ll discover that ground-up plastic isn’t the same as new pellets; it’s lighter and requires some extra processing before it can be melting and drawn out as a constant diameter fiber. These extra steps include a 3 mm extrusion followed by pelletizing. Ultimately, we end up with a 100% recycled feedstock that can be used for producing 3D printer filament or in any thermoplastic processing equipment (e.g., injection molding). #recycling #filament #3dprinting Table of Contents: 00:00 - Intro 01:29 - Recycling 3D Prints 01:58 - Shredding (Reclaimer) 07:55 - Extruding regrind 14:38 - Pelletizing 17:40 - Degradation 20:10 - Re-Extruding 21:15 - Economics 24:00 - Recycling Commodity Plastics 27:10 - Pultrusion 29:00 - Shredding PET Bottles 30:35 - PET Extrusion Challenges 35:15 - Extruding PET Flakes
