To support everyone who produces 3D-printed PPE, such as face shields, we decided to make Prusament PETG Orange for PPE available with a heavy discount.

This Prusament PETG is primarily made for printing PPE (Personal protective equipment). The material composition matches Prusament PETG Prusa Orange, however, to speed up the production, the diameter tolerance is ±0.03mm and the winding is not as perfect as on the usual Prusaments. It's still a high-quality filament, which we've been using on our print farm for a long time.



In reaction to the acute shortage of protective wear for medical personnel in the current pandemic situation, we started producing Prusament PETG Orange for PPE. Our goal is to offer quality materials suitable for the current situation.


This Prusament is designed primarily for anyone printing personal protective equipment. We made an open-source face shield and provide all of the files, FAQ and assembly manual at


The manufacturing process is faster due to not so strict diameter tolerance ±0.03mm and faster winding. Unlike standard Prusament, spools do not have their unique ids and cannot be checked on our website.


Even though anyone can order it, this Prusament is mainly for those in need of material for printing PPE. Less pretty winding, lower diameter tolerance than standard Prusament, lower price, but still a quality material which is ideal to print PPE effectively and fast - we use it, too!

About PETG

PETG is a very tough material with good thermal resistance. Its use is universal but especially suitable for mechanical parts and both indoor and outdoor use. PETG has almost no warping, so printing large objects isn’t a problem. We use PETG to print parts for our printers!

PETG is one of our favorite materials for 3D printing. It’s almost as easy to print as PLA, but it can offer many mechanical properties that PLA prints just cannot achieve. The G in the acronym PETG stands for Glycol which is added during the manufacturing process. Glycol modifies the properties of PET, so that it’s easier to print, less brittle and clearer when printing with semi-transparent variants. PETG has low thermal expansion, so even when printing big objects, and without an enclosure, it rarely lifts from the bed and warps. In addition to that, PETG is ductile. It has a healthy amount of flex which can prevent parts from breaking under pressure.

Unlike PLA or ABS, PETG tends to ooze a bit and may leave strings of plastic on your print. You can fight this with increasing retraction and playing with hotend temperature, but if you use our filament presets in Prusa Slicer, we already did that for you and the amount of stringing is minimal. If you witness a tiny bit of stringing anyway, you can get rid of it by quickly blasting your finished prints with a heat gun.

If you can handle the oozing and strong adhesion, you’ll be left with a very durable print, that is considerably temperature resistant and usable for both indoor and outdoor use.
