GP20 Plastic Shredder 

Prepare your materials for extrusion and material development workflows.  

Reduce plastic waste into consistent, reusable flakes ready for extrusion, testing, and material development. Designed for labs, R&D teams, and pilot-scale environments, GP20 helps teams take control of material input before processing begins.

An essential step between waste, material preparation, and controlled extrusion workflows.  

Trusted in Material Development Workflows Worldwide

Built for Material Preparation and Workflow Control

GP20 is a compact shredding system designed to prepare plastic materials for extrusion, testing, and material development workflows.

It allows teams to reduce plastic waste into consistent flakes, creating a reliable starting point for further processing.

Used across R&D labs, pilot environments, and industrial teams, it helps standardize material input before extrusion, supporting more predictable and controlled results in downstream workflows.

Role in the Material Workflow

From Material Input to Extrusion-Ready Feedstock 

GP20 is used at the beginning of the material workflow to prepare plastic input for further processing, enabling consistent and reusable feedstock for extrusion and testing.

Material Preparation

Reduce plastic waste, prints, or raw materials into consistent flakes suitable for further processing.

Feedstock Standardization

Create a more uniform material input to improve handling, feeding, and consistency during extrusion.

Workflow Integration

Feed prepared material into extrusion systems such as Filament Maker ONE and TWO for testing, validation, and application workflows.

What it Enables

Material Preparation For Testing And Processing

Prepare plastic materials into consistent flakes suitable for extrusion, testing, and material development workflows.

In-House Material
Input Control

Bring material preparation in-house to reduce dependency on external suppliers and control the quality of feedstock used in your process.

Reuse of Internal
Material Streams

Process failed prints, scrap, or waste material into reusable input for further experimentation or development.

Improved Consistency in Downstream Processing

Start with more uniform material input, helping improve feeding behavior and reduce variability during extrusion.
