摘要

如今，3D打印熔丝制造(FFF)目前在实现高打印速度方面存在障碍，主要是由于无法足够快地处理长丝。本文介绍了热动力流动分析的结果进行了热动力的商业设计，目的是为了找出设计参数与较高的发生率的材料输出的质量流，因此，在印刷的速度和质量。通过有限元热分析来表征材料和几何设计元素对热管的影响。通过分析，得到了商品熔体的行为，商品熔体的行为以及几何形状和材料变化对商品熔体的影响。控制变量为每个模型的腔室体积和玻璃化过渡体积。这些结果将被用作新主机的设计标准。

Thermal Analysis by Finite Elements of Hotends for 3D Printing by Fused Filament Fabrication

Nowadays, 3D printing Fused Filament Fabrication (FFF) currently presents obstacles to achieve high printing speeds, mainly due to the inability of the hotend to process the filament fast enough. This article presents the results of the thermodynamic flow analysis carried out on commercial designs of hotends, in the aim intending to identify the design parameters with a higher incidence in the mass flow of material output, so therefore, in the speed and quality of printing. Finite elements thermal analysis was carried out performed in order to characterize the effect of the materials and geometric design elements of the hotends. In this analysis the behavior of the commercial, the commercial melters' behavior and the effects caused by the changes in geometry and materials were obtained. The control variables were the chamber volume and the glass transition volume of each model. These results will be used as the design criteria of a new hotend.
