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

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
