“…This underperformance is also seen in comparisons of injection molded and ME manufactured ABS tensile, flexural samples where ME samples are 30 % to 70 % the strength of injection counterparts 58 , and in ULTEM 4 tensile samples where the z-axis tensile strength is 50 % of the injection molded counterpart. 59 We do not observe a plateau at short weld times, which might be expected somewhere below 0.1 s 0.5 , which we ascribe to our inability to print at or below 200 °C and so we cannot access short enough relative weld times.…”

“…In order to smoothen the threads of the modular parts, chloroform vapor was used to treat the 3D prints. It has been previously demonstrated that chloroform can not only reduce the roughness, but also increases the tensile strength of specimens in the upright build direction, increasing the overall material quality [30]. About 50 mL chloroform was poured in a glass beaker inside a fume cupboard, and heated to 250°C.…”

“…While Griffiths et al [36] studied the influence of FDM build parameters on processing efficiency and performance of build parts, Srivastava et al [37] employed response surface methodology for optimizing FDM process parameters such as (contour width, raster width, air gap, raster angle, slice height and orientation). From the foregoing and other similar studies [38]- [44], it has been reported in literature that FDM build parameters have enormous effects on cost optimization and performance properties of ABS and other polymeric based materials. Despite that mechanical properties of polymers material are critical for their structural applications, available studies on the influence of FDM build parameters on the mechanical properties of 3D-printed polymer materials are limited.…”
