The KLM story




Reflow rPETG Recycled filament

Chemical name: Polyethylene Terephthalate – Glycol Modified
Source of plastic: The Netherlands
Description: Our flagship rPETG is sourced from leading local recyclers. Its durable and easy to use, with exceptional visual and mechanical performance.

Available colours: White ~ Black ~ Aqua ~ Mint ~ Honey ~ Coral

Diameter: 1.75 mm. °0.05mm / 2.85 mm. °0.07mm
Roundness: 98%
Net filament weight: 1 KG
Filament length: 357m / 137m

A versatile middle ground between PLA and ABS.

PET-G Is stronger than PLA but easier to print with than ABS. The glycol in this material makes the filament less brittle and resistant to water, chemicals, and solvents. It is naturally clear, making it the go-to filament for translucent prints. 
The strength and durability of a PET-G filament vary depending on the brand. An easy way to check if one PET-G is stronger than another is by comparing the tensile strength value of each filament. If printed in a sterile, FDA-approved environment, PET-G can be used to create food-safe prints.

Due to its strong and durable nature, PET-G can be difficult to finish with post-processing methods such as sanding. Prints may also be difficult to paint or glue together. Depending on printer and slicer settings, you may experience small hairs over the surface of prints caused by stringing. These can be removed with a heat gun or lighter.

Used for: Water Bottles, Plant Pots.
