Abstract

This article analyzes the influence of layer height on the tensile strength of PLA specimens printed in the Fused Deposition Modeling (FDM) technology. The maximum breaking force of specimens with 30% and 100% infill density was determined at layer height of 0.05 mm, 0.1 mm, 0.2 mm and 0.3 mm. In the case of 30% infill, the highest value of the force was obtained for a layer with a height of 0.05 mm (which corresponds to 22.7 MPa), and for a 100% infill for a layer of 0.2 (which corresponds to 40 MPa). Over this layer height of 0.2 mm is the most polyoptimal due to the time prints and strength (which corresponds to 19.7 MPa).

层高对FDM打印试样抗拉强度的影响
本文分析了层高对熔融沉积成型(FDM)技术打印PLA样品抗拉强度的影响。在层高分别为0.05 mm、0.1 mm、0.2 mm和0.3 mm时,测定了30%和100%填充密度试样的最大断裂力。当填充量为30%时,层高为0.05 mm时受力最大(对应22.7 MPa),当填充量为100%时,层高为0.2 mm时受力最大(对应40 MPa)。由于打印时间和强度(对应于19.7 MPa),该层高度为0.2 mm是最优的。
