What is PETG-HF, and when should I use it?

PETG-HF stands for a high-flow variant of PETG (Polyethylene Terephthalate Glycol), optimised for faster printing and robust results.

Advantages: High strength and durability; better temperature resistance than PLA; improved flexibility compared to brittle materials; good resistance to chemicals and wear.

Considerations: As with many stronger plastics, achieving clean prints might need more careful settings. PETG is more suitable for functional or load-bearing parts rather than purely decorative prints.

Ideal for: Functional components, mechanical parts, items needing durability or some heat/chemical resistance — e.g. practical objects, housings, tools, enclosures.
