Transcript of Anisoprint - 3D printing of continuous fiber reinforced plastics
Anisoprint3D-prinitng of continuous fiber reinforced composites
ProblemModern 3D-prinitng technologies are divided into to major groups
Cheap, but not capable for func-tional parts production
Production of end-use parts, but expensive
• FDM• SLA
Equipment cost around $ 1000
Low material cost
Material – plastic with low mechanical properties
Materials – metals or ceramics with superior properties
• SLM
Average equipment cost around $ 500 000 High material prices
There are no affordable solutions on the market, capable for functional parts production
Comparison of 3D-printing with automated composite manufacturing technologies
WindingWell-known processHigh productivityRequires curingTooling is requiredOnly convex shapes

Reinforcing fiber
Composite FDM
Mechanical properties:Strength – from 20 to 120 MPa; Stiffness – from 2 to 6 GPaMaterials used: PLA, ABS, PA, PC, PEIBy adding continuous fibers to FDM 3D- printing process mechanical properties can be increased 10-20 times
Mechanical propertiesStrength – up to 1000 MPa; Stiffens – up to 60 GPaReinforcing fibers: Carbon, glass, aramidPlastics: PLA, ABS, PA, PCSpecial treatment of reinforcing fiber ensures impregnation quality and better adhesion to plastic material
Continuous fibers 3D-printing
Technology advantages
• Strong – Mechanical properties are close to aerospace com-posites
• Real 3D – allows to print in pure 3D (using 3D-printed sup-ports)
• Versatile – allows the use of different thermoplastics and reinforcing fibers
• Tailorable – allows the local variation of fiber path and fiber volume fraction for optimal parts production
• Easy – based on FDM technology• Feasible – uses specially pre-
pared carbon fiber tow, which guarantees good impregnation of fiber and adhesion of fibers to plastic

Complex shape parts
The technology allows to steer the fiber to produce complex shape tailored parts
End use
Space – lattice structures, reflectors, fittings, sandwich panels
Aircraft – interior parts, fittings, tubes
Health – individual insoles, prostheses, orthoses, exoskeletons. Automotive – sport cars, tuning
UAVs, Robotics: frames, casingsWearables: individual protection, buckles, acces-sories, fashionRotating parts: shafts, gears
