Filabot
EX3 - Filament Extruder
Choose options
Advanced filament extrusion, made accessible.
The Filabot EX3 is the accessible entry point into professional filament extrusion for education programs, research labs, MakerSpaces, recyclers, and material development teams that want more control over the way filament is made.
Built on a new platform, the EX3 makes professional extrusion more accessible without placing it in the hobbyist category. It gives users the ability to create, test, recycle, and produce filament from pellets, recycled feedstocks, powders, additives, fillers, and custom material blends.
The EX3 is designed for teams that want to understand the full material journey, from feedstock and formulation to filament quality and final print performance.
Material in. Filament out. Full control in between.
Designed to Innovate With You
The EX3 delivers high torque and smooth, precision controlled extrusion to support stable screw speed, consistent flow, and repeatable high quality filament production, even when processing demanding materials.
With high thermal stability and extended temperature capability, the EX3 opens access to advanced polymers, high performance materials, and demanding R&D applications.
A long 14:1 L/D barrel improves mixing, melting consistency, and process control while minimizing material degradation. Interchangeable screws and nozzles allow users to quickly optimize for different materials, fillers, and applications.
From standard polymers to powders, additives, filled materials, and recycled feedstocks, the EX3 was designed for material flexibility. Advanced feeding and anti-clog support improve flow consistency across a broad range of formulations.
The EX3 is built to last and serves as the foundation of a broader material development ecosystem, allowing users to expand into cooling, spooling, recycling, and larger workflows as their needs evolve.
Built for Better Filament Workflows
Making reliable filament requires more than melting plastic. Feedstock, screw design, nozzle selection, temperature, motor control, cooling, pull rate, and spooling all influence final filament quality.
The EX3 gives users a practical way to bring that process in-house. Whether you are developing new materials, teaching material science, recycling failed prints, or validating a custom blend, the EX3 helps you move from raw material to usable filament with greater control.
Interchangeable Screw and Nozzle Options
Different materials behave differently during extrusion. The EX3 supports interchangeable screws and nozzles so users can better match the extrusion process to their material, feedstock, and application.
Useful when a material or process benefits from conveying without added compression.
A general-purpose option for common filament extrusion workflows and standard pelletized feedstocks.
Designed to support applications where additional compression helps optimize the material processing goal.
Interchangeable nozzle options give users another way to tune the EX3 for different filament sizes, materials, and workflow requirements.
Designed for Education, R&D, and Recycling
Help students move beyond printing and into material science, extrusion, recycling, and process control.
Develop, test, and validate new polymers, additives, fillers, recycled streams, and custom formulations in-house.
Turn prepared plastic feedstocks into usable filament and support circular material workflows.
Part of the Filabot Ecosystem
The EX3 is more than a standalone extruder. It is an accessible starting point within the broader Filabot ecosystem.
Users can begin with extrusion, then expand into cooling, diameter measurement, spooling, and recycling as their workflow grows.
Prepare plastic waste, failed prints, scrap, or recyclable material for reuse.
Convert pellets, regrind, or prepared material into filament.
Stabilize and control the filament as it exits the extruder.
Collect finished filament into clean, usable spools.
Use the finished filament in 3D printing applications.
- Compatible with Filabot Airpath
- Compatible with Filabot Waterbath
- Compatible with Filabot Spooler systems
- Compatible with Filabot Spooler Max for larger runs
- Compatible with Filabot Filameasure for diameter measurement
- Expandable into full recycling and filament production workflows
For users working from raw pelletized feedstock, the workflow may begin at extrusion. For users recycling material, the workflow can begin with reclaiming plastic before extrusion.
