PETG Carbon Fibre

About PETG – Carbon Fibre:

Our PETG – Carbon Fibre is essentially our PETG Pro infused with Carbon Fibres for added strength/rigidity and lighter weight parts, we recommend printing with a hardened nozzle.

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.

PETG is one of our favourite 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 ASA, 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, we find a retraction speed of 25mm/sec and 2mm of retraction for direct drive or 4 to 6mm for Bowden setups does the trick to keep the amount of stringing 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.
