Filament
Maker V2
PET bottles to 1.75mm filament.
The Filament Maker V2 is a benchtop machine designed and built in the UK by Sustainable Design Studio, for makers, classrooms, and product designers who want to print with their own recycled PET. Wind any PET bottle 1L or larger into 1.75mm filament, ready to spool and load into any 3D printer.
- UKCA and CE certified
- 12 month worldwide warranty
- Carbon neutral shipping
92g of filament an hour, made from the bottles already in your bin.
A 1L PET bottle that costs nothing becomes 1.75mm filament ready to spool. The Filament Maker V2 pulls one continuous strand through a heated nozzle in real time, no pellets to dry, no extruder to clean down. Faster than most desktop printers can lay it down.

Any PET bottle, 1L or larger
2L bottles produce the most filament per bottle. Larger bottles work too. Cut a clean strip, feed it in, and let the heated nozzle pull it through.
1.75mm consistent diameter
Output drops onto your spool ready to load into any 1.75mm 3D printer. Tested print profiles for rPET are included in the resources pack.
Worldwide voltage compatible
Runs from a 12V DC mains adapter at 4A (48W). 100-120V or 220-240V mains, with UK, EU, NA, or AU plug supplied for the country you ship to.
Watch the Filament Maker V2 pull a bottle into a spool
From cut bottle strip to filament on the spool, the whole cycle, uncut. Watch the cutter prep, the nozzle pull, and the auto-wind spool in real workshop conditions.
Technical specifications
Every figure below is published in the Filament Maker digital product passport and verified against the build guide.
Output and feed rates assume a steady supply of clean PET bottle strip. Print quality with the resulting filament depends on drying and printer profile (guidance on the resources page).

Five refinements, one redesigned machine
Faster throughput
Pull filament faster. V2 lifts the output rate from 84g/hr on V1 to roughly 92g/hr, around an hour saved on a full 1kg spool.
Sharper heating precision
A more accurate heater holds the nozzle inside a tighter window than V1, which means more consistent diameter and fewer surprises on long prints.
Stronger plastic parts
The plastic components inside the V2 are reworked for stiffness and lifespan, less play in the drive train and a longer service interval than V1.
Easier kit assembly
Fewer parts, a simpler build path. The V2 mechanical design strips out the fiddly steps from V1 so a first kit build is faster from unboxing to first spool.
Same price
Every upgrade above lands at the V1 price. From £190 as a kit, the FMV2 stays the cheapest plastic-bottle-to-filament machine we make.
