As 3D printing becomes increasingly integrated into professional design practice—from architectural modelmaking to experimental fashion and product development—the issue of material waste continues to grow. Failed prints, support structures and purge blocks accumulate quickly, often ending up in storage boxes or, ultimately, the bin. The new ExtrudeX system, designed by Creative3DP, aims to close this loop by offering designers a compact, accessible and fully 3D printable filament-recycling machine.

Closing the Loop in the Studio

ExtrudeX allows users to convert their own PLA or PETG waste into fresh filament directly on the desktop. Instead of investing in large industrial recycling units, designers can print most of the machine’s structural components themselves and add a small number of off-the-shelf mechanical parts. The idea is simple: shred or break down leftover prints, mix them with virgin pellets, and re-extrude the blend into new 1.75 mm filament.

The recommended recipe—around 60% pellets and 40% waste of the same polymer—helps maintain print quality while significantly reducing material consumption. For design studios exploring bio-based or recycled plastics, ExtrudeX provides a practical way to experiment with circular material flows on a small scale.

Designed for Practicality

The machine is intentionally compact, measuring under 650 mm in length, allowing it to sit next to a standard desktop printer without dominating the workspace. Its operation is deliberately straightforward: a motor drives a screw through a heated metal tube, melting the plastic mixture before extruding it through a nozzle. A short cooling path and a 3D printed puller stabilise filament diameter, while an optional digital gauge mount allows real-time monitoring.

Because most of the components are printable, designers can modify or replace machine parts as needed—supporting a mindset of repairability and local production. A transparent bill of materials ensures all non-printable parts can be sourced globally, supporting independent makers and small studios.

Towards Circular 3D Printing

For architects, product designers, fashion innovators and packaging specialists, ExtrudeX offers a hands-on tool for testing circular design strategies. When combined with PETFusion 2.0—a complementary, also DIY-printable system that turns PET bottles into filament—the setup enables a complete micro-recycling environment, turning consumer waste and 3D-printing scrap into new material streams.

ExtrudeX demonstrates how accessible, small-scale recycling technologies can transform how designers think about prototyping materials, waste reduction and on-site material production. By enabling a closed filament loop within the studio, it supports both sustainability goals and creative experimentation.
