ReForm rPET is likely to be the most sustainable PETG-based filament on the market. This filament is completely made from renewed materials. There are no virgin fossil- or virgin natural resources used to make this PETG filament. This sustainable PETG filament combines strength and toughness with printability.

ReForm rPET profiles are available on the Ultimaker Marketplace. ReForm rPET is an approved and validated partner material.



ReForm = Sustainability ↑ + Prices ↓

ReForm by FormFutura offers sustainable filaments made from renewed materials only. We have packaged our ReForm filaments in our most sustainable packaging ever. It is our goal to reduce not only our footprint, but also the retail prices. Sustainability and affordability can go hand in hand.

  • Renewed materials only, no virgin fossil- or virgin natural resources used.
  • All FormFutura packaging is 100% recyclable.
  • Spooled on sturdy recycled and FSC certified cardboard spools.
  • Packaged in recycled and climate neutral cardboard boxes.
  • Reform is the first filament range that is available on industrial-sized cardboard spools.
  • Unbeatable retail prices for high-end and sustainable filaments.


Big spools with a small footprint

ReForm combines sustainability and affordability into top-notch filament. ReForm brings sustainability to both desktop- and large scale 3D printing. All ReForm filaments are available on five types of cardboard spools ranging up to 4.5 kg!

ReForm is the first filament range that is available on industrial-sized cardboard spools. FormFutura is changing the game for both desktop- and large scale 3D printing. It doesn’t matter if you print with 0.25kg sample spools or industrial-sized 4.5 kg spools. You are now assured that your filament comes on a cardboard spool. By that, we strive to keep our (and your) footprint as low as possible.
High-end, sustainable and affordable
ReForm filament is manufactured in the Netherlands according to ISO 9001:2015 standards.
This 3D printing filament is not only friendly for our ecosystem, but also for your budget. Sustainability does not have to come at a higher retail price. ReForm proofs to be high-end, sustainable and also very affordable. Let’s reform additive manufacturing with ReForm by FormFutura!

FormFutura rPET filament is made up entirely from recycled post-industrial PETG content sourced from the waste streams that arise during the extrusion or our HDglass filaments. Because of its high recycled content, rPET filament is not made from a virgin natural PETG compound, but from a homogeneous compound made from a wide variety of colors from collected filament extrusion waste. Homogeneous compound runs can vary in color intensity. This may result in lighter or darker 3D printing filament colors extruded from various homogeneous compound runs. On average two to three homogeneous compound runs are made per year.
rPET White and Black will always have the same color, as extrusion waste from black and white PETG filament is collected separately.


General printing guidelines*

Nozzle size: ≥ 0.15mm Layer height: ≥ 0.1mm Adhesive: EasyFix Nr. I
Print temp: ± 230 – 240° C Fan speed: 0 – 30% Experience level: Beginner
Heat bed: ± 75 – 85° C Enclosure: No / Recommended  

*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends and printer offsets that it is extremely difficult to give an overall one-size-fits-all setting.
