Polymaker Releases New Fiberon PET-GF15 Filament for Durable, Easy Prints

The latest release from Polymaker adds to the company’s Fiberon line of technical materials and promises impressive performance across a range of rugged criteria.

Fiberon PET-GF15 starts at $32.99 for a regular 1kg spool, although introductory pricing appears to have it on offer at $28.04. It’s available in a variety of colors, and can be bought on larger 3kg spools, too.

Glass fiber composites typically offer similar boosts to mechanical strength and printability to carbon-fiber filled materials, making it a go-to low-cost alternative.

Printability is what Polymaker is pushing as the key to PET-GF15. Billed as a material to “bridge the gap between everyday usability and industrial performance”, you can use it in an AMS or other filament switching device without worrying about the filament snapping, making it effectively a drop-in replacement for regular PETG with the benefit of stiffness and stability at high temperatures. A nice bonus to glass-filled filaments like this is that the “rough” texture transfers to prints, hiding layer lines well.
