熔融沉积成型工艺中构建时间的研究
Study on Build Time in Fused Deposition Modeling Process

为了解决熔融沉积成型制造中存在零件原型构建时间过长的问题，本文在研究了零件原型构建时间产生机理的基础上，给出了构建时间的理论计算方法并分析了影响构建时间的因素。以不同边长的实心立方体为例，通过理论计算得到的构建时间与实验所用构建时间相对比，分析了产生时间差值的影响因素，得出了零件原型体积与构建时间的数学关系式，进一步为缩短零件原型构建时间提供了研究方向。
In fused deposition modeling system, prototype parts are accumulated and formed with hot extrusion nozzle fuse. However, the problem is that the build time of prototype parts takes longer. Therefore, based on the mechanism of the build time of prototype parts, the calculation method of the build time is drawn in order to solve the above-mentioned problem. In this paper, through the solid cube with different lengths, the calculated build time is compared with the experimental, then the factors affecting the difference in the generated time is analyzed, and finally the relationship between the prototype parts volume and build time is presented so as to provide a reference for prototype parts for shortening the build time
