HI-Temp CF


SKU: N/A Category: Tags: , , ,

BigRep’s HI-TEMP Carbon Fiber (CF) is a high-strength and heat-resistant engineering-grade filament. Highly stiff and incredibly durable, the material effectively maintains its form under high heat conditions. Ideal for the thermoforming process, HI-TEMP CF is the perfect match for the production of patterns and moulds. With an excellent combination of heat and UV resistance – rivalling ASA – and durability, its also ideal for functional applications regularly exposed to heat – such as in automotive or automation.

A reliable and easy to use the material, BigRep HI-TEMP CF is optimized for large-format 3D printing and suitable for environments with limited control like factory floors.
