New Innofil3D EPR PET Filament as a Promising PLA Alternative

28 Jul

Innofil3D, a company specialized in making 3D printer filaments has released a newly developed filament called ERP PET that promised better results and features than traditional PLA filaments and the new ERP PET should come at a similar or slightly higher price point. PET (Polyethylene Terephthalate) is well known for its wide application in making plastic bottles and it has great characteristics to bring 3D-printing to the next level. Currently PLA and ABS are the most common used monofilaments for 3D-printing. PLA is nice for consumers, but printed objects have their limits. ABS gives great results but users can experience difficulties when using it on their printer and most people dislike the smell during printing and it is not healthy to breath the fumes.


So here comes EPR PET promising to be a a great alternative for both, a new PET-based filament specifically designed for 3D printing from Innofil3D. It is easy to use, doesn’t generate fumes, shows great detail and is recyclable. EPR PET has a larger operating window for printing (temperature vs. speed) so it can be used on every 3D-printer and there should be no need for a heated bed since EPR PET adheres very well on tape. According to Innofil3D their ERP PET filament should be as easy to print as PLA and the resulting print should be better in terms of Strength, Resolution and Appearance thus making it a great alternative to standard PLA and allowing users to use the new filament for things where PLA may not be good enough. The glass transition temperature of the ERP PET filament is listed at 62 degrees Celsius or with other words the thermal resistance is similar to that of standard PLA where normally that temperature is about 55-60 degrees Celsius. We have a spool of the new ERP PET filament from Innofil3D to try out the new material, so we are going to be sharing our feedback from using it and how it compares to PLA very soon.

Recommended printer settings for ERP PET:
– Nozzle temperature: 210-230 °C
– Heated bed temperature: 75-85 °C (when applicable)
– No heated bed: use tape for bed adhesion
– Printing speeds: 40-100 mm/s (depends on nozzle temperature)
– Layer height: 0.08-0.2 mm
– Layer thickness: 0.8-1.0 mm thickness makes it possible to print water tight objects
