Abstract

The application of fused filament fabrication (FFF) in vacuum changes the heat transfer of the process. This work investigates the influence of the working ambient pressure conditions in FFF-based 3D printing of polyetheretherketone (PEEK) specimens, and its impact on the resulting part strength. Layer adhesion drastically improves with decreasing pressure, maximum layer adhesion is reached for ambient pressure below mbar. We show that simple and low-cost vacuum equipment is sufficient to achieve such pressure conditions, making this process interesting for the general processing of high-temperature polymers using FFF.

摘要

在真空中应用熔融长丝制造（FFF）会改变该工艺的热传递。这项工作研究了基于FFF的聚醚醚酮（PEEK）试样3D打印中工作环境压力条件的影响及其对所得部件强度的影响。随着压力降低，层间附着力大幅提高，当环境压力低于毫巴时达到最大层间附着力。我们表明，简单且低成本的真空设备足以实现这种压力条件，这使得该工艺对于使用FFF进行高温聚合物的一般加工很有吸引力。
