Filament spool Gembird PETG 1.75 mm Blue 1 kg

Gembird PETG 1.75 mm Blue 1 kg filament spool is a general-purpose 3D printing material made from Polyethylene Terephthalate Glycol (PETG). Designed for FDM/FFF printers that accept 1.75 mm filament, this single 1 kg spool provides a balance of strength, slight flexibility and chemical resistance appropriate for functional parts, prototypes and everyday prints. The blue filament is suited for faster printing workflows and is compatible with a wide range of machines, including high-speed and CoreXY systems.

Advantages

PETG combines clarity and toughness, offering higher impact resistance than acrylic and a cost-effective alternative to polycarbonate. The filament melts reliably for improved flow at high speeds, enabling printing in sport and ludicrous modes on supported machines. It exhibits very low shrinkage for better dimensional stability on large flat surfaces, good chemical resistance, and prints well on common build surfaces such as acrylic, glass and Kapton. The material is recyclable, supporting environmentally conscious printing choices.

Suitable for

• Functional prototypes and mechanical parts that require impact resistance
• Large flat prints where low shrinkage is important
• High-speed printing workflows on printers like Bambu Lab, Creality K1(max), FF 5M(PRO) and Voron
• General-purpose models, jigs and fixtures

How to use

Load the 1.75 mm PETG filament into any compatible FDM/FFF printer according to the printer manufacturer’s filament loading procedure. Recommended starting settings include a nozzle temperature and print speed adjusted for PETG and the specific printer: increase temperature and flow as needed to achieve reliable extrusion at higher speeds. Use a suitable build surface such as glass, acrylic or Kapton and ensure proper bed adhesion via adhesives or settings when required. Monitor first layers to confirm correct extrusion and adhesion before running long prints.

Usage recommendations

Start with manufacturer-recommended or community-tested temperature and speed profiles for PETG on your printer model. For high-speed printing, tune retraction, extrusion multiplier and cooling to reduce stringing and ensure dimensional accuracy. Store the spool in a dry environment or sealed bag with desiccant to maintain filament quality.
