RP America Expands Open-Material Ecosystem with 3devo Desktop Extrusion Systems

In-house filament production has traditionally required industrial-scale equipment and dedicated floor space. 3devo's desktop extrusion systems change that equation, and RP America is proud to bring them to the North American market.

RP America has partnered with 3devo to offer their desktop extrusion systems as part of our growing additive manufacturing technology portfolio. This collaboration gives facilities across the U.S. the hardware to process raw pellets, plastic waste, and spent SLS nylon powder into production-ready FDM filament — on the production floor, on demand.

Close the Loop on Material Waste

The 3devo ecosystem is built around a straightforward idea: the thermoplastic sitting in your scrap bin is still a usable material. With the right equipment, failed prints, support rafts, regrind, and even spent SLS nylon powder can be processed back into consistent, industrial-grade filament without sending it out, without waiting on a supplier, and without paying disposal fees.

The workflow starts with the GP20 Grinder, a high-torque shredder that breaks rigid plastic waste down into uniform granules ready for extrusion. It processes up to 5kg of material per hour and features a fully accessible cutting chamber for fast cleaning between material changeovers, which keeps contamination out and throughput up.

From there, material feeds into the star of the system: the Filament Maker TWO.

Filament Maker TWO — Precision Where It Counts

Producing filament that actually performs on the print floor requires more than melting plastic through a nozzle. Diameter consistency, thermal stability, and repeatable output are what separate usable feedstock from expensive scrap. The Filament Maker TWO is built around those demands.

• Thermal Control: A multi-zone heating barrel ensures precise polymer melting across a wide range of materials, from commodity plastics to high-performance engineering polymers.
• Real-Time Diameter Stabilization: An integrated optical sensor measures filament diameter continuously and automatically adjusts puller speed to maintain consistent output tolerance.
• Automated Spooling: A tension-controlled winding system lays filament neatly onto spools without operator intervention, keeping production moving without babysitting the machine.
• Open Material Platform: No proprietary material locks. Process everything from PLA and PETG to PEEK, PEI, carbon-filled blends, and spent SLS nylon powder.

One important note for nylon and SLS powder workflows: engineering polymers are highly hygroscopic, and extruding damp material causes voiding, brittleness, and diameter inconsistency. A dedicated drying cycle before loading material into the hopper is a required step for reliable filament density.

Materials You're Already Working With

The Filament Maker TWO handles the full spectrum of thermoplastics that AM facilities encounter daily.

• Low-temperature materials: PLA, PETG, ABS, PP, HDPE
• Engineering polymers: TPU, Nylon (PA6, PA12), PC, POM
• High-performance materials: PEEK, PEKK, PEI
• Composite inputs: carbon fiber, glass fiber, ceramic and metal powders, polymer blends
