Renkforce RF-6838904 filamento PETG 1,75 mm 1 kg preto

3D printing with standard PLA can leave you with brittle parts that crack under stress or deform in warm environments. This Renkforce PETG filament solves that by combining the ease of printing you expect with the durability of engineering-grade materials. It delivers strong, impact-resistant prints with excellent layer adhesion and low warping, making it ideal for functional prototypes, mechanical parts, and outdoor applications.

Who is it for

Makers, engineers, and hobbyists who need reliable, tough parts without the hassle of ABS. If you print brackets, enclosures, drone components, or anything that must withstand knocks and temperature swings, PETG is your go-to material. It is also food-contact safe and odourless, so it suits household items and workshop use.

Main features

• High impact resistance and flexibility – parts bend rather than snap
• Excellent layer adhesion for strong, void-free prints
• Low warping and shrinkage – prints large models without lifting
• Chemical resistance to many common solvents and oils
• Vacuum-sealed with desiccant to keep filament dry and print-ready
• Recycled plastic spool supports sustainable printing

Tips

Store PETG in a dry box or resealable bag with silica gel when not in use. For best results, print on a heated bed with a thin layer of glue stick or blue tape to protect the surface. If you experience stringing, reduce nozzle temperature slightly and increase retraction distance. PETG adheres strongly to PEI sheets – use a release agent to avoid damage.
