A recent series of major developments and events has created a new impetus for 3D printing plastic recycling. 3D printing of recycled plastics has multiple benefits, including lower costs and control over the amount of materials that can be used by 3D printers. Currently, 3D printing filament is produced by melting down virgin plastic pellets and extruding the melted plastic through a circular die which is then rolled up into spools. Printing with pellets or recycled materials is more cost effective and energy efficient than printing with new plastic filaments. In addition, direct printing of plastic pellets eliminates the need for further processing and therefore makes them less expensive.
Plastic has always been one of the leading 3D printer material categories. Now there is an expanding global concern about the amount of plastic product waste and in particular its negative impact on oceans and waterways. Improved pellet 3D printing recycling technology can play an important part in helping solve this environmental problem. 3D printing product developers, engineers, designers and environmentalists working on pellet recycling projects have the opportunity to earn US R&D tax credits.
