EX3 Extruder Set Up
Choose options
The Filabot EX3 Filament Set-up gives educators, researchers, makers, engineers, and manufacturers the ability to produce high-quality 3D printing filament from pellets, recycled plastics, powders, and custom material formulations.
Whether you are developing new materials, recycling plastic waste, reducing filament costs, or building a closed-loop 3D printing workflow, the EX3 System puts you in control of the complete process — from raw material to finished spool.
Built on more than fifteen years of extrusion experience and shaped by feedback from thousands of Filabot users, the EX3 System delivers the process control, material flexibility, and reliability needed to help you recycle, innovate, and produce with confidence.
Material in. Filament out. Full control in between.
Explore more materials with the confidence to innovate, teach, and discover.
Whether you're developing the next generation of polymers or trying to understand the science behind filament production, the EX3 provides the process control needed to turn ideas into consistent, high-quality filament.

Why Make Your Own Filament?
The EX3 System puts you in control of your filament quality and cost.
Choose your materials, optimize your process, reduce material costs, and produce high-quality filament on your own schedule.
Whether you're developing new materials, recycling plastics, or creating custom formulations, the intuitive EX3 gives you the accessibility, flexibility and confidence to innovate faster.
Designed for Material Innovation
Material innovation rarely starts with a finished spool. It starts with: What if we try this?
Researchers test new formulations. Students explore recycling. Engineers evaluate additives and fillers. Makers experiment with colors, recycled streams, composites, and custom compounds.
Before developing the EX3, we asked more than 4,000 Filabot users what empower and delight them. The EX3 System reflects what we learned, giving users the critical process capabilities to push boundaries with easy to use controls and analytics to produce consistent, usable filament.
Eliminate BoundariesWork with pellets, powders, recycled plastics, additives, fillers, and advanced formulations up to 425C processing temperatures |
Produce with ConfidenceHigh torque motor with interchangeable screws and nozzles for greatest stability and repeatability when processing demanding or low melt flow materials. |
Ensure QualityCoordinate extrusion, cooling, pulling, measurement, and spooling easily for a more controlled and predictable result. |
Experiment RapidlyFaster material, screw and nozzle changes and better visibility help users test, learn, and iterate more efficiently. |
A Complete Filament Production Workflow
To produce reliable filament every stage matters: extrusion, cooling, pulling, diameter control, and spooling.
The EX3 Filament Maker System brings these steps together into one coordinated workflow, helping users move beyond basic extrusion and into controlled filament production.
EX3 ExtruderMelts, mixes, and pushes material through the nozzle to create filament with improved stability and control. |
AirpathStabilizes filament for consistent processing. Upgrade to the Waterbath for faster, enhanced cooling. |
SpoolerPrecision pulling and automatic winding for consistent filament. Available with the 10 kg Spooler Max for larger production runs. |
Filameasure & LoggerMonitors and analyses filament diameter for better process control and repeatability. |
Inspired by You. Engineered by Filabot.
EducationHelp students move beyond printing and into material science, extrusion, recycling, and process control through hands-on learning. |
Research & DevelopmentDevelop, test, and validate new polymers, additives, fillers, recycled feedstocks, powders, and custom formulations in-house. |
MakerSpacesHelp members create, recycle, and experiment with their own materials instead of only using commercial filament. |
Additive ManufacturingReduce dependence on commercial filament suppliers and produce application-specific filament when you need it. |
Sustainability ProgramsBuild practical circular manufacturing workflows by transforming prepared plastic waste into usable filament. |
Engineering TeamsPrototype custom materials, evaluate process windows, and support material decisions earlier in development. |
Part of the Filabot EcosystemThe EX3 System is more than a standalone filament maker. It is an entry point into the broader Filabot circular material ecosystem. Start with extrusion, cooling, measuring, and spooling. Then expand into drying, shredding, advanced cooling, larger spooling, analytics, and future Filabot workflow solutions as your needs evolve. All supported by the Filabot portfolio. |
