Abstract

Fused deposition modeling (FDM) is a rapidly growing 3D printing technology. However, printing materials are restricted to acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) in most Fused deposition modeling (FDM) equipment. Here, we report on a new high-performance printing material, polyether-ether-ketone (PEEK), which could surmount these shortcomings. This paper is devoted to studying the influence of layer thickness and raster angle on the mechanical properties of 3D-printed PEEK. Samples with three different layer thicknesses (200, 300 and 400 μm) and raster angles (0°, 30° and 45°) were built using a polyether-ether-ketone (PEEK) 3D printing system and their tensile, compressive and bending strengths were tested. The optimal mechanical properties of polyether-ether-ketone (PEEK) samples were found at a layer thickness of 300 μm and a raster angle of 0°. To evaluate the printing performance of polyether-ether-ketone (PEEK) samples, a comparison was made between the mechanical properties of 3D-printed polyether-ether-ketone (PEEK) and acrylonitrile butadiene styrene (ABS) parts. The results suggest that the average tensile strengths of polyether-ether-ketone (PEEK) parts were 108% higher than those for acrylonitrile butadiene styrene (ABS), and compressive strengths were 114% and bending strengths were 115%. However, the modulus of elasticity for both materials was similar. These results indicate that the mechanical properties of 3D-printed polyether-ether-ketone (PEEK) are superior to 3D-printed ABS.

摘要

熔融沉积建模（FDM）是一种快速发展的3D打印技术。然而，在大多数熔融沉积建模（FDM）设备中，打印材料仅限于丙烯腈丁二烯苯乙烯（ABS）或聚乳酸（PLA）。在此，我们报告一种新型高性能打印材料——聚醚醚酮（PEEK），它可以克服这些缺点。本文致力于研究层厚和光栅角度对3D打印PEEK力学性能的影响。使用聚醚醚酮（PEEK）3D打印系统制作了具有三种不同层厚（200、300和400μm）和光栅角度（0°、30°和45°）的样品，并测试了它们的拉伸、压缩和弯曲强度。发现聚醚醚酮（PEEK）样品在层厚为300μm和光栅角度为0°时具有最佳力学性能。为了评估聚醚醚酮（PEEK）样品的打印性能，对3D打印的聚醚醚酮（PEEK）和丙烯腈丁二烯苯乙烯（ABS）零件的力学性能进行了比较。结果表明，聚醚醚酮（PEEK）零件的平均拉伸强度比丙烯腈丁二烯苯乙烯（ABS）高108%，压缩强度高114%，弯曲强度高115%。然而，两种材料的弹性模量相似。这些结果表明，3D打印聚醚醚酮（PEEK）的力学性能优于3D打印的ABS。
