BioPETG is a professional grade PETG combined with our proprietary bio-additive technology that delivers a sustainable PETG filament, without compromising material performance.
How does BioPETG work?
Our bio-additive simply provides a food source for bacteria living in active landfill facilities and commercial composts, but 3d printed parts maintain the strength, pliability, heat resistance, chemical resistance, and post processing capabilities of PETG in every way, delivering a more sustainable 3d printing experience.
BioPETG meets both ASTM D5338 and ASTM D5511 standards for biodegradability.
ASTM D5338 determines the degree and rate of aerobic biodegradation of plastic materials by measuring a percentage of conversion of carbon in the sample to carbon dioxide. ASTM D5511 measures anerobic biodegradation.
(Average results of combined tests)
In independent tests 3d printed parts made with BioPETG provide a constant food source for the bacteria in each test vat, and measurements showed steady production of CO2 during the entire 45 day test period.
In multiple test vats containing 3d printed parts made from pure PETG, measurable CO2 production is primarily a result of the bacteria cannibalizing each other. Bacteria in these vats isn’t able to convert the carbon in plastics into CO2 very efficiently, but as the bacteria in an area attempts to feed they produce an electrical charge that attracts other bacteria in the vat. As bacteria discover the plastic is not a viable food source, they then begin feeding on each other. In every test CO2 production was steady initially, but fell significantly roughly halfway through testing as the bacteria itself was consumed.
Key Features on Performance & Sustainability:
- Physical properties of base material are unchanged
- Maintains the shelf life of base resin
- Degradation begins only at the time of disposal
- Degradation is not initiated by exposure to heat, light, oxygen, or external stresses during storage or use
- No special storage conditions required
- Bio-additive contains no heavy metals and is ecologially and environmentally safe
- Bio-additive returns to the environment as biomass
BioPETG combines many of the benefits of ABS with the ease of printing associated with PLA in one material:
- High impact resistance
- High strength and durability
- Excellent layer adhesion
- Excellent pliability
- Very low shrinkage, therefore little to no warping making it deal for large prints
- Smooth finish
- No heated bed required
- High temperature resistance
- Odorless printing
- Excellent chemical and water resistance
- Excellent geometric accuracy
- Can be sterilized
- Strong but flexible (ideal for drones, mechanical parts, & robotics)
- FDA compliant
As with all materials there is a settings "sweet spot" that will vary from one printer to another. BioPETG is no different, but once you're dialed in printing with BioPETG is a dream. Here are some general setting guidelines:
- Set your nozzle temperature between 230°C and 250°C.
- Print with cooling fan at 100%
- A heated bed is not required but start between 70°C - 80°C if available.
- Set print speed around 55mm/sec or less.
- Try starting with an additional .2mm gap in the Z axis to avoid skimming
Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.

1. What is an Active Landfill?
Active Landfills or Landfill to Energy facilites contain a high concenreation of leachate bacteria that promote decompostion and produce landfill gases like methane that is catpured, refined, and used to produce energy.
There are over 3,000 active landfills / landfill to energy facilities in the US, and hundreds of commercial composts.
2. How long will it take for my parts to degrade?
This is probably the question we're asked most often, and the answer depends a lot on the overall mass, infill percentage, size, and geometry of any given part. Also the conditions in an active landfill or compost will differ from one location to another. And bacteria concentrations will even vary within a single facility. BioPETG (or PLA's for that matter) certainly won't ever degrade the way a banana peel will, but when we extrapolate the ASTM tesing data BioPETG delivers a markedly more sustainable material than standard PETG.
3. Will my parts degrade under normal use conditions?
Great question and NO! The leachate bacteria concentration in active landfills needed to initiate the degradation process is extreme. Your BioPETG parts will stand the test of time until you decide they've reached end of life.

Made in the USA with 100% resins and precision manufacturing combined to deliver the ultimate in consistent 3d printing for hobbyists to Industry 4.0.
Every inch of BioPETG is measured to ensure that it is within the strictest standards for quality, diameter, and ovality. BioPETG is 750g of filament wound onto a heavy recycled cardboard spool that is biodegradable and bound with a recyclable tin end cap. In fact the entire spool can be tossed directly into your recycling bin!
The spool includes both a cutout for viewing filament and dual puncture slots to secure filament when not in use. The flange can even rotate to in either direction to aid in securing the filament wherever it has been cut. The spool was specifically designed for universal fit with most 3d printers in use worldwide and is compatible with Ultimaker printers.
Each spool of BioPETG is carefully wound to exacting standards to minimizing crossovers and loopbacks that can lead to snags and snaps. In addition, a portion of the proceeds from every spool of BioPETG will be donated to plant a tree. Every spool helps rejuvenate iconic forests in key locations throughout the United States.
