研究目的
Investigating the remelting of FLM surfaces via laser beam polishing as an effective method for achieving a reduced roughness.
研究成果
Laser beam polishing is a feasible method for significantly reducing the surface roughness of FLM-printed parts, with certain polymers like PLA, PMMA, and SAN showing the most promising results. However, the process requires careful parameter optimization to avoid material decomposition and achieve the desired surface quality.
研究不足
The study is limited by the specific polymers tested and the laser parameters used. Further research is needed to explore a wider range of materials and optimize the polishing process for industrial applications.
