The industrial sectors are undoubtedly the ones that have the most advantages with the introduction of 3D printing into their production processes. During the first years emerging of this technology, there are certain technical essentials of the printed models which were not able to meet the required parameters.
These requirements could be classified mainly in: mechanical resistance, thermal resistance and resistance to chemical agents.
During the last year, many RD researches have proliferated concerning the manufacture of new materials applied to 3D printing using FDM technology (fused deposition modelling) which have led to the production of materials capable of covering the aforementioned spectrum of technical requirements.
In this post, we want to present one of these special materials, carbon fiber filament a filament which is consisted of carbon fibers. PRIMASELECT CARBON
This material is optimized to be printed on medium and high-range 3D printers given the thermal requirements of printing. Wrking with this filament is extremely easy given its composition: PETG (80%) + Carbon fibers (20%). These carbon fibers intertwined with each other and make possible to print very high mechanical resistant parts.
The range of printing temperature of carbon fiber is between 240-260ºC for the extruder and 60-80ºC for the hot bed. Typical temperatures of materials composed of PETG.
While it provides unparalleled features in the mechanical part, the impression of this material has a ‘negative feature’ which is solvable. It can cause a high degree of abrasion in the extruder nozzle. However, this “problem” ceases to be so with the use of specially treated or produced nozzles such as hardened steel nozzles or nozzles with coating treatment.
