Any extrusion-grade thermoplastic, blend or recycled stock. You decide what goes in the hopper.
About ASTER
Built for the People Who Make Materials
ASTER builds ASTER-C, a benchtop filament extruder that lets labs, print farms and material developers turn their own polymers and blends into 3D printing filament, in-house.

Why we built it
The Formulation Was Never the Hard Part
You already know what you want to run: a high-temperature grade with a specific filler, a recycled batch from your own workshop, an unusual diameter. Getting it as filament is where the work stalls.
- 01
Lead times
Research cycles measured in supplier lead times instead of bench hours.
- 02
Minimum orders
Money spent on minimum order quantities for material you will barely use.
- 03
Untested ideas
Formulations you never test, because testing them is not worth the wait.
- 04
Wasted scrap
Reclaimable scrap thrown away for want of a way to process it.

What we believe
How We Think About Filament
Small Batches Count
Run just enough to test an idea, without supplier minimum orders or long lead times.
Scrap Is Feedstock
Suitable failed prints and process scrap go back through the machine as usable filament.
Honest Numbers
Every figure on this site comes from the ASTER-C specification sheet and operating manual.
