Outline of Final Research Achievements

After improving the heat nozzle of the 3D printer of the Fused Deposition Modeling method, the modeling conditions were examined. Using an improved Fused Deposition Modeling 3D printer, we succeeded in producing a model of polyetheretherketone, which is one of the biomaterials. There is a difference in the mechanical properties, crystallinity and crystal orientation of polyetheretherketone depending on the scanning speed of the heat nozzle, which is one of the modeling conditions.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は，造形条件によって，生体材料の一種であるポリエーテルエーテルケトン造形体の結晶の配向性や結晶化度を制御できることおよびそれを利用してポリエーテルエーテルケトン造形体の機械的性質を制御できる可能性を示唆している．生体骨は，個々形状が異なり，機械的性質は異方性であるため，３D プリンタの得意とする形状コントロールと結晶の配向性を制御できる材質コントロールを同時にできることは社会的意義が大きい．
