Bonding Quality of Materials Fastly Modeling by Fused Deposition

The bonding quality of materials fastly modeling by fused deposition directly determines the mechanical performance and service effect of the elements made of such material. In the light of technological tests and based on theoretical analysis,the authors probe into the bonding quality of several polymeric materials under different technological conditions.A summary is made on optimal temperature range at nozzle,temperature range in modeling room and reasonable slice thickness of different materials fastly modeling by fused deposition. The results provide a basis for optimized controlling technological parameters of different materials modeling by fused deposition.
