CREAMELT® TPU-R
DESCRIPTION
CREAMELT® TPU-R is an elastic filament for 3D printers, 100% made from recycled ski boots. The material is based on thermoplastic polyurethan (TPU) witch is used for the main cover of ski boots. To reuse the material, old ski boots are collected and disassembled by people with disabilities at ARGO workplace in Davos. After chemical analysis and color sorting, the collected plastic is shredded, remelted and extruded to new 3D filaments.
Because TPU-R is made of 100% recycled material, some minimal differences in printing and color properties are possible between individual spools.
CREAMELT® TPU-R gives you the ability to design and print durable elastic objects made from recycled materials and is a sustainable alternative to virgin material.
Since the TPU is a very hygroscopic material that absorbs a lot of moisture from the environment, pre-drying before printing and storage in a dry storage box during printing is strongly recommended. This is the only way to prevent bubble formation on the printed component and maximize print quality.

TECHNICAL DATA SHEETSTART SHOPPING
This plastic recycled from old ski boots is yet another striking demonstration that sustainable, recycled goods are more than equal to new goods – technically, functionally and aesthetically.
