Filament made from plastic waste: Creality teases recycling combo M1 (extruder) and R1 (shredder)

Creality hints at an internal filament processing system consisting of the R1 Filament Shredder and the M1 Filament Maker. The R1 is designed to shred 3D printing waste or pellets into particles measuring just a few millimeters. This is intended to enable a uniform material flow for the second step. The M1 extrudes the ground material, heats it in a similar way to the FFF process, and forms it into new filament. A winding spool is integrated to directly collect the freshly extruded strand.

The announcement is being made on Creality’s in-house crowdfunding site, a Kickstarter-like platform. A campaign has not yet been officially launched there. The company has not yet announced the price or availability. Instead, Creality is relying on teaser graphics, animations, and an email list for notifications.

Desktop filament recycling has been considered challenging for years. In practice, many projects failed due to three factors: the systems were expensive, they required careful adjustment, and the quality of the result often fell short of purchased filament. Currently, there are only a few providers active in this area. One example is 3DEVO, but their machines are more suited as tools for laboratories that produce small quantities of experimental filament. Creality could lower the entry price through high volumes and a large installed base.

Parameters such as feed rate, temperature control, and humidity play a central role in operation. Creality has established management functions in its desktop printers for years and could transfer similar control loops to a recycling system.

The crowdfunding page provides key technical data on output performance and dimensional accuracy: up to 1 kg per hour should be possible. A diameter tolerance of ±0.05 mm is specified for new pellets and ±0.1 mm for recycled pellets. This means that the dimensional accuracy of recycled material is below the level of many manufacturer filaments. In addition, repeated heating changes the polymer structure, which can alter strength and printing behavior over time. Sorting remains another bottleneck: homogeneous spools require similar material and as consistent a source as possible. Realistic areas of application are therefore more likely to be medium-sized printing farms that have large quantities of uniform waste and can tailor their own profiles for recycled filament.
