FFF (fused filament fabrication) also known as FDM (fused deposition modeling) is an additive manufacturing technology, where an object is printed by extruding thermoplastic material layer by layer. Various materials are available for FFF. The best known representatives are Polylactic acid (PLA) and Acrylonitril Butadiene Styrene (ABS), but also other thermoplastics preferred with amorphous structure are available for printing. However, the industry demands for cost-effective materials possessing properties such as high chemical and corrosion resistance, higher impact strength and better temperature stability. In addition, the process stability and documented quality control are key issues to ensure an everyday deployment in industries.

PROFACTOR is interested in the development of methods for 3D-printing of polyolefins using the fused filament fabrication (FFF) technology. The goals are realized with analyses of commercially available filaments, development of tailored polyolefin compounds and adaptions to the printer, the printing-software and implementation of inline control systems.

  • Structure-property-relationship derived from the characterization of commercially available filaments enables the preparation of tailored materials with low shrinkage coefficients and good dimensional stabilities
  • Process-control system, based on near infrared sensors, heat-flow thermography, and optical size accuracy measurement technologies enables quality control of individual parts.
  • Hardware adaptions and process parameter optimization enables the production of parts using special materials

PROFACTOR enables interested companies and educational instituts the possibility to experience the 3D printing technologies in form of a mobile open lab. Please contact us for more information.
