Continuous ﬁber 3D printing allows manufacturing composite parts of high strength and low weight. Using anisoprinting it’s possible to produce optimal composites — the structures that are optimized in the way the part can demonstrate the maximum strength whilst spending minimum material for it.
Anisoprinted composites are 30 times stronger than pure plastic; 7 times lighter than steel; 2 times stronger & lighter than aluminum. The approach is based on so-called Composite Fiber Co-extrusion technology.
Reinforcing material is made from dry continuous ﬁbers (carbon or basalt) preliminary impregnated with the special polymer mix. They’re called Composite Fibers since they are already composites. Pre-impregnation provides low porosity and gives a good adhesion of reinforcing material to thermoplastic during the further printing process. Learn more about reinforcing materials’ properties in CCF&CBF section.
During the printing thermoplastic is reinforced with Composite Fiber. Composite extruder has two inputs: one for reinforcing material and the other for thermoplastic. You can use any plastic with the processing temperature up to 270°C as a matrix material (e.g. PETG, ABS, PC, PLA, Nylon, etc).
Reinforcing ﬁber and plastic go separately in the same extruder so you can vary ﬁber volume ratio and lay it by complex curvilinear trajectories. In this way, it's possible to print composite parts of complex shapes with lattice inner structure that is the optimal form for composites due to their unidirectionality.
Strength and stiffness of the composite lay along the ﬁber that’s why the lattices which consist of one-dimensional ribs are the optimal shape for composites. With the composite inﬁlls, you can get maximum strength spending minimum material that means minimum weight, production time and price of the part.
As a result, you get a two-matrix composite part of any shape, without tools or molds, without machining and post-processing. Several times stronger and lighter than plastic, metal or non-optimal 3D printed composites:
