PETG Filament.

Polyethylene Terephthalate Glycol-modified (PETG) provides an accessible middle ground between PLA and ABS. Belonging to the polyester family used in drink bottles and clothing fibres, its glycol modification makes the polymer forgiving to print on standard machines. You get tough, functional parts without the thermal warping and bed adhesion difficulties typical of ABS.

The material delivers high impact resistance and flexes under load rather than snapping under stress. Strong layer bonding keeps parts together under handling, while efficient cooling yields minimal warping and a smooth, glossy surface finish. Its raw material meets EU 10/2011 and FDA 21 CFR 177.1315(b) for food contact. That covers the material we buy, not the object you print, so verify suitability for your own application before you use it that way. It is a versatile choice for everyday and functional parts.

We manufacture this filament in Haarlem using a dry extrusion process with no water bath. We vacuum-seal every spool at the source so it arrives dry, keeping a consistent diameter and roundness across the entire spool.

This filament prints reliably on standard desktop and industrial machines. It resists warping far better than ABS while remaining almost as simple to print as PLA. You get dependable results without needing specialised high-temperature hardware.

Handling and storage.

The best results come from a stable printing environment with no drafts and no temperature fluctuations. Keep the printer out of direct sunlight, and do not place it in a room where people sleep. When you finish printing, seal the spool in a bag. Store it in a cool room between 15 and 25 °C, dry and out of UV light.
