Finite Element Analysis and Manufacture of Porous Structure Based on SLM Technique

摘要

Selective laser melting (SLM) technique has been widely used in stomatology in recent years because of the advantages of its digitization and efficient. However, information about it is limited. What is more, studies have shown that porous structural dental implants based on SLM technique is beneficial to combination of implant and bone tissue. In this study, designing and manufacturing new types of porous implants based on SLM technique and performing simulation from the perspective of biomechanics are the main content. The results show that hollow structure has higher stress and strain in stress-concentration areas compared with solid structure. However, these differences would not form great influence. There are not obvious defects for the samples based on SLM technique on surface.
