Abstract

Spherical carbon particles were prepared by using waste Guilin rice noodles as raw materials. By blending the rice noodles based carbon (RC) powders with polylactic acid (PLA), A series of black RC/PLA 3D printing composites were synthesized and characterized. The mechanical testing result shows that the RC/PLA 3D printing composites display better mechanical properties than that of pure PLA. Moreover, the composite with carbon treated with high temperature carbonization has better impact strength.
