Prusament PETG Jet Black 1kg

PETG is a very tough material with good thermal resistance. PETG has universal use, but is especially suitable for printing mechanical parts. It can be used both indoors and outdoors. PETG has very low thermal expansion, so it does not warp on the bed and therefore there is no problem with printing large models. Parts for our printers are printed from PETG! PETG is one of our favorite materials for 3D printing. Printing with it is almost as easy as with PLA, but unlike PLA it can offer many better mechanical properties. The letter G in the acronym PETG stands for glycol, which is added during the manufacturing process. Glycol modifies the properties of PET to make it less brittle, easier to print, and more transparent when printing with semi-transparent variants. PETG has low thermal expansion, so even when printing large models, it rarely warps and peels off the heated bed. In addition, PETG is tough, just flexible enough and, as a result, often only temporarily bends under stress, which prevents cracking. Unlike PLA or ABS, PETG tends to string a bit, i.e., pull thin strands of plastic during travel. You can combat this by increasing retraction and lowering the temperature, but if you are using our preset profiles in Prusa Slicer, we have already done that for you and the amount of stringing should be minimal. If you still encounter it, you can get rid of it by quickly (a few seconds) passing a heat gun over the finished prints. If you deal with stringing and filament oozing and strong filament adhesion, you will get very durable prints. Thanks to decent heat resistance, PETG prints are also suitable for outdoor use.
