摘要
熔融沉积快速成型,是利用热塑性材料的热熔性、粘接性特点,在计算机控制下根据实体模型进行层层堆积后成型。基于熔融沉积快速成型过程中熔体对成型制品的质量影响,对成型过程中熔体的流动性及热平衡进行数值分析,优化熔融快速成型工艺熔体参数,为喷头装置的设计提供依据,保证成型制品的质量。
Fused deposition rapid prototyping means accumulating molding according to solid model by the characteristic of hot melt and adhesive of thermoplastic materials under the control of the computer.Based on the affection that the quality of mold-ing products on melt during the fused deposition modeling process, flow and heat balance in the process of forming are numeri-cally analyzed, the molten melt parameters of rapid prototyping technology are optimized,which provides the basis for the de-sign of the nozzle device, and can ensure the quality of forming product.
