    Abstract:

    In order to solve the problem of fused deposition modeling application in space, the forming process test of different materials was carried out on earth.PLA,PC,PEEK and carbon fiber reinforced PLA materials were selected as the research objects in the experiment.The standard samples were successfully printed with the self-developed space microgravity principle prototype, and the mechanical properties, fire resistance, gas concentration after combustion, total mass loss and condensable volatile properties of the samples were tested. The tensile properties of carbon fiber reinforced PLA samples with different fiber directions and the performance difference between FDM and injection samples were studied. The result shows that the material bonding ability is the main factor affecting the performance of FDM parts, and the bonding strength between different materials is the main factor affecting the properties of the composite samples. The higher bonding ability is, the higher the FDM forming quality of the material is. Meanwhile the forming quality of the crystalline material is also affected by the crystallinity. The higher crystallinity is, the better workpiece performances are.
