Material in. Filament out. Full control in between.

The EX3 is Filabot's newest extruder, designed from feedback gathered from more than 800 EX2 users. It delivers high material flexibility, robust process control and ease of operation so students, researchers, makers and recyclers can create, test, recycle and produce their own filament without stepping up to a large industrial system. Direct, intuitive controls make the extrusion process visible and teachable, while a powerful motor and 425 °C heat capability leave room to grow into engineering and high-performance polymers.

Designed to innovate with you

• High torque for precision-controlled extrusion — 33 Nm (292 in-lb) of torque and 0–42 RPM control keep flow smooth and repeatable, even with demanding, low-MFI or filled materials.
• Up to 425 °C processing — a thermal window wide enough for advanced polymers and high-performance materials such as PEEK and ULTEM.
• Versatile screw and nozzles — a long, interchangeable 14:1 L/D screw (no-compression, standard and high-compression profiles available) improves melt consistency while minimizing degradation. 1.75 mm and 2.85 mm nozzles are included; others are available.
• Broad material compatibility — from standard filled pellets to powders, additives and recycled feedstocks, with anti-clog feeding for consistent flow.
• A scalable platform you won't outgrow — start with extrusion, then add cooling, measurement, spooling and recycling as your needs evolve. When you need more output, swap in an EX6 and keep all of your downstream equipment.

Who it's for

• Education — hands-on extrusion, recycling and material-science learning on a realistic equipment budget. Filabot offers curriculum support for teachers.
• Makerspaces & engineering teams — a professional, compact platform for custom filament, prototypes and experimentation.
• Recycling & sustainability programs — convert failed prints, purge and scrap into usable filament and build a circular workflow.
• Research & material-development labs — test formulations, fillers, powders and difficult polymers in-house instead of waiting on outside suppliers.

Fast payback. A school, makerspace or print farm that recycles roughly 2,000 kg of material a year can pay back a complete Filabot system in under six months versus buying new filament—while teaching hands-on polymer science along the way.

Part of the Filabot Modular Ecosystem

Every Filabot machine is a building block. The equipment is modular, so you can start with the workflow you need today and expand later—adding cooling, measurement, spooling, pelletizing or shredding—without replacing what you already own. All units are bench-top sized and run on standard 110 V single-phase power (no 3-phase required), so a complete line fits comfortably next to your 3D printers.

The EX3 covers the Extrude stage. Build it out in any direction:

• Add the Airpath Filament Cooler to stabilize filament diameter as it leaves the nozzle (strongly recommended for higher-temperature polymers).
• Add the Spooler to pull, traverse and wind finished filament onto 0.5 kg or 1 kg spools.
• Add the Filameasure to the Spooler to measure diameter live and log data with Filalogger.
• Add the Pelletizer to chop filament into pellets for re-extrusion, compounding or injection molding.
• Add the Reclaimer to shred failed prints and scrap into granulate the EX3 can extrude.
• Need more throughput or four-zone temperature control? Step up to the EX6 Standard Filament Extruder or EX6 Industrial Filament Extruder — all of your Filabot downstream equipment carries over.

Compatible materials

PLA, PETG, ABS*, HIPS*, PA (Nylon), PC, PO, PEI (ULTEM), PEEK, TPE, TPU, wax and other low-MFI polymers; virgin pellets, recycled regrind, powders, mild additives and fillers. *Ensure proper ventilation and filtration—some materials can emit harmful fumes. Final compatibility depends on screw, nozzle, processing conditions and formulation.

What's included

• EX3 Filament Extruder (110 VAC)
• Removable standard screw
• 1.75 mm and 2.85 mm nozzles
• Extruder cleaning kit
• User manual and power cord

Specifications

*Published output is PLA mass flow at the nozzle. Finished filament throughput depends on polymer, formulation, diameter, cooling and spooling.
