摘要：

Six kinds of Ti-6A1-4V artificial bone scaffolds were designed and built with SLM (selective laser melting) technology. Universal material testing machine and high-speed camera were used to analyze the compression process of scaffolds, and Ansys was used to analyze the stress of scaffold. The results show that the vertical column diameter has a great influence on the mechanical property of scaffolds but the beam diameter has little influence on them; under the same height, the increasing of beam diameter and layer or support column diameter, result in structure length-diameter ratio decrease, so that structure is firm and load-carrying capacity improves. The mechanical property should match with the surrounding bone tissue. Through the analysis, mechanical property of three kinds of scaffolds are close to human femur, so they can be used as the artificial bone scaffolds of femur.
