Carbon Fiber 3d Printer Filament Strength

Several popular filaments can be bought with carbon fiber fill including pla petg nylon abs and polycarbonate.

Carbon fiber 3d printer filament strength. Carbon fiber makes the 3d printing material stronger and sturdier. Whereas carbon fiber consists of a continuous strand the filament is a combination of short carbon fiber strands and some printable material either pls abs petg or nylon depending on required properties and durability. If you are already printing with nylon its time to upgrade. Since the carbon fiber is not chopped up into smaller pieces it retains much more of its strength.

Carbonx cf abs is a high performance carbon fiber reinforced abs filament ideal for anyone that desires a structural component with high modulus excellent surface quality dimensional stability light weight and ease of printing. 3d printer manufacturers claim that it can replace metal 3d printing for some applications the main advantage being it is cheaper than metal. Its excellent strength and lightweight properties also translate to advantages in using carbon fiber filaments in 3d printing. In three point bending our 3d printed carbon fiber is 8x stronger than abs and 20 stronger than the yield strength of aluminum.

The fibers aid in preventing any parts from shrinking as the print cools down. The strength of the carbon fibers provides better dimensional stability to the filament reducing chances of warping or shrinkage. Carbon fiber filament is not the same as carbon fiber materials. These fibers are extremely strong and cause the filament to increase in strength and stiffness.

Nylonx is an engineering grade nylon filament which is blended with chopped carbon fibers approximately 20 by weight creating a high strength filament capable of printing tough shatter resistant functional parts. Nylonx is the perfect blend of strength and durability. Made using 15 high modulus carbon fiber not carbon powder or milled carbon fiber. In fact continuous carbon fiber 3d printing is strong enough to replace aluminium at half the weight.

The 3d printers from anisoprint use continuous carbon fiber reinforcements while giving the user maximum freedom in material choice and reinforcement positio. Even though we used the same 3d printer and the same settings for all the parts there was quite a bit of variance in load before failure.
