ROSA FILAMENTS for 3D printing

The PET-G+CF filament by Rosa3D was designed for printing structural elements and moving parts of machines, where higher durability and heat resistance are required.

PET-G+CF printouts are characterised by negligible moulding shrinkage, they are odourless and feature very strong bonding between layers. The material has a graphite, matte surface and a smooth, almost sateen, structure, and is relatively easy to print. Negligible moulding shrinkage allows for printing in an open device.

The PET-G+CF filament features a strong chemical resistance and the addition of carbon fibre enhances its mechanical and heat durability as well as its impact strength, which ensures universal application of this material.

For PET-G+CF printing it is recommended to use hardened steel nozzles (brass and aluminium nozzles can be subject to abrasion), suggested size > 0.3mm.

Recommended print temperature: 240- 270 °C

Recommended temperature of the table: 70-90 °C
