ROSA FILAMENTS for 3D printing

The PA + 15CF filament by Rosa3D is a combination of nylon and carbon fibres. Combining the advantages of both materials allows to obtain a new product of extraordinary durability.

The PA+15CF filament printouts are suitable for continuous work in temperatures exceeding 160°C.

PA+15CF printouts can easily be used as substitutes for steel elements in order to reduce the total mass of the device or the construction.

PA+15CF is characterised by its easy application in printing and, thanks to the carbon fibre filling, it features minor moulding shrinkage. Recommended especially for semi-professionals and advanced users. In printing with PA+15CF it is recommended to use hardened steel nozzles (brass and aluminium nozzles can be subject to abrasion), suggested size > 0.3mm.
