Study on Properties of Polymer Materials Based on 3D Printing Technology

Abstract

3D printing is a new processing technology, which has developed rapidly in recent years. In addition to industrial production and civil fields, it is also widely used in aerospace, military, medical, and other fields. Material used for 3D printing usually needs to have a more prominent adhesion performance to ensure a strong bonding force between multi-layer materials, so as to support the three-dimensional forming of products. Generally speaking, polymer materials such as wire, photosensitive resin, and polymer powder can be used for 3D printing. The experimental results show that the engineering plastics printed by 3D will have obvious anisotropic characteristics. It is brittle in the transverse direction and has broken before reaching the plastic stage, but it shows obvious elastic–plastic characteristics in the vertical direction. It goes through the linear elastic stage first, and then goes through the plastic softening stage.
