Abstract

Polylactic acid (PLA) is a biodegradable material widely used in biomedical field. In order to improve the performance of pure PLA, 316 L stainless steel content of 10 vol% to 60 vol % was added to the PLA matrix. Powder physical characteristics tester was used to explore the angle of repose, the angle of collapse, the angle of flat plate and compressibility, the integrated thermal analyzer was for detecting thermal properties of PLA/316 L stainless steel composite. The results showed that the angle of repose and angle of collapse of the composite decreases first and then increases with the increase of 316 L stainless steel powder. The angle of flat plate and compressibility was reduced by the addition of steel powders. When the 316 L stainless steel powder content is 50 vol %, the fluidity of the composite is the best. The high melting point of 316 L stainless steel powder increases the melting point temperature of composites. The prepared PLA/316 L composites can be applied to 3D printing technology represented by fused deposition modeling (FDM).
