Key takeaways
- Filabot announced the EX3 Filament Maker System on September 25, 2026, as a complete benchtop platform that combines extrusion, cooling, diameter monitoring, and automatic spooling for custom 3D printing filament.
- According to Additive Manufacturing Media (citing Filabot), the system targets universities, labs, material developers, manufacturers, makerspaces, and recycling programs that want to turn virgin pellets, recycled plastic, regrind, or experimental formulations into filament in-house.
- Filabot says the EX3 can produce 1.75 mm and 2.85 mm filament plus custom diameters, and can process thermoplastics including PLA, PETG, nylon, polypropylene, TPU, and TPE, with results depending on formulation, moisture, particle size, and process settings.
- The lesson for working shops is not "buy a filament line tomorrow." It is treat material choice as a controlled input: name the duty cycle, prove the polymer, then print and ship the part.
Most additive news is about a bigger printer or a flashier lattice. Filabot just published something quieter and more practical for anyone who lives with materials: a complete benchtop filament maker that turns pellets, regrind, and experimental mixes into printable filament under one roof.
According to Additive Manufacturing Media (published September 25, 2026, sourcing Filabot), Vermont-based Filabot announced the EX3 Filament Maker System as a coordinated workflow: extrude, cool, pull, monitor diameter inline, and spool automatically. Frederik Klaarenbeek, CEO of Triex LLC (Filabot's parent), framed the need plainly: researchers and manufacturers want more control over the materials they use in additive manufacturing, and the EX3 is meant to move from raw or recycled feedstock to finished filament inside the user's own lab.
That is the whole story in one sentence: material control on the bench, then a print that matches the duty cycle you actually have.
What did Filabot actually announce?
A complete benchtop filament system that pairs extrusion with cooling, diameter control, and spooling so labs can make custom filament in-house.
Coverage says the EX3 package includes the Filabot EX3 Filament Extruder, Airpath cooling, Spooler, nozzles in two sizes, purge material, cleaning tools, accessories, and documentation. Target jobs listed by Filabot include polymer and additive research, recycled-plastic evaluation, custom formulation, materials-science education, colorant and additive testing, small-batch filament production, and closed-loop manufacturing research. Filabot manufactures and supports the system from Barre, Vermont, with North American and international electrical configurations and a three-year limited warranty, per the same announcement.
The company is clear that processing results depend on the material and the settings. That honesty matters. Filament diameter and moisture are not marketing bullets. They are process variables that decide whether a print succeeds.
My fixture needs a specific polymer blend. Do I need to make my own filament?
Usually no. Start with a proven engineering polymer and a trusted CAD model, then only invent feedstock when the job truly requires it.
Lab filament makers are for people who must change chemistry on purpose. Most plant fixtures, nests, adapters, and enclosures need a known material that already survives heat, chemicals, or continuous load. When the duty cycle is harsh, engineering polymers such as PEEK and ULTEM already do serious work today. That is why we run a PEEK and ULTEM high-temp parts path for buyers who need performance without standing up a materials lab first.
Steal Filabot's design question anyway. Can you name the polymer, moisture risk, and failure mode in one sentence? If you cannot, the bottleneck is specification, not a new extruder.
We have a worn OEM part and no material callout. What should we do first?
Capture the geometry and the mating interfaces, then choose material from duty cycle evidence, not from a guess about the old plastic.
Headlines about custom filament are exciting. The daily failure mode is quieter: a discontinued bracket, a cracked nest after a line change, a latch the OEM will only sell as a full assembly. That is a scan-to-CAD problem before it is a materials problem. Measure what is on the floor, rebuild design intent, mark what you know versus what you inferred, then pick the polymer.
If that is the hole you are in, our 3D scanning and reverse engineering service exists for that workflow. Ship the part or start from photos and measurements. You get a manufacturable model instead of another guess against a faded label.
What this means if you actually need parts this month
Filabot's announcement is a clean materials loop: control feedstock, measure diameter, spool, then evaluate prints. Your version of that loop is smaller and more practical.
- Write down the load, heat, chemical, and wear environment.
- Get a trusted CAD model (OEM file, or scan and rebuild).
- Choose a known polymer for that duty cycle before inventing a blend.
- Fit-check a prototype when the interface is unforgiving.
- Move to a short production run without a minimum-order trap.
When you want that last step handled in the USA with a $20 minimum order, our Build and Ship workflow takes a file or a concept through to finished parts. We are not claiming we run a Filabot EX3 on the floor. We are saying the same discipline (prove the material and the model, then ship) is how custom polymer parts should get made for makers and plant teams.
If you need a desk or lobby piece that is not a fixture at all, our raised city map page covers an 11 by 11 inch raised city map for office decor or a gift. Different job. Same rule: lead every project to a real page on the site.
Frequently asked questions
What is the Filabot EX3 Filament Maker System?
According to Additive Manufacturing Media's September 25, 2026 report citing Filabot, it is a complete benchtop platform that combines extrusion, controlled cooling, filament pulling, inline diameter monitoring, and automatic spooling so users can produce custom 3D printing filament in-house.
Which materials can the EX3 process?
Filabot lists thermoplastics including PLA, PETG, nylon, polypropylene, TPU, and TPE, and says results depend on formulation, moisture, particle size, melt flow, temperature, cooling, and downstream settings.
Do I need custom filament to get a heat-resistant fixture?
Usually no. Most shop fixtures start with a known engineering polymer matched to heat and chemicals, plus a trusted CAD model. Custom filament research is a different job than printing a nest that has to survive the line.
I need a replacement part and the OEM plastic is unmarked. Who do I email?
Email info@dcadditivepros.com with photos, rough dimensions, duty cycle, and quantity. We will tell you straight whether scan/RE, high-temp polymer, or Build and Ship is the right next step.
