...Valentina Furlan; Federico Insero; Hermes Giberti Purpose This study aims to investigate and compare three nonplanar (NP) slicing algorithms. The algorithms aim to control the layer thickness variation (LTV), which is a common issue in supportless fabrication of free-form parts. The comparison...

.... This change in parameters such as layer thickness and infill density impacts mechanical properties such as hardness and surface roughness, which will influence the contact mechanism with the counter body during any tribological test. The change in a single parameter during the sample fabrication...

... strength, pore morphology and distribution are investigated. Experimental samples were fabricated in two different layer thicknesses (50 and 100 µm). Findings While 15–45 µm samples demonstrated higher green density (53.10 ± 0.25%) than 5–25 µm samples (50.31 ± 1.06%), higher sintered densities were...

...-dimensional (3D) printed by SLA process is still limited. Therefore, this study aims to investigate the effect of different process parameters on the compressive properties. Design/methodology/approach In the present study, the influence of layer thickness, infill density and build orientation...

... technique, the most frequent defect is bleed wherever the jetted water drops are occupied by the adjacent powder bed. Bleed usually takes place in all three increase. Bleed can often differ due to the nature of the powder bed and the amount of water dropped. 3D printing Layer thickness Mechanical...

...) was preliminarily analyzed. The speed of the hopper for powder deposition was set at 2,000 mm/min under environmental conditions of 20°C and relative humidity of 50%. No pressure was applied on the powder in the hopper. The powder layer thickness was kept at 2 mm. The flowability was visually inspected upon...

... of PLA were evaluated by using variable process parameters. Findings The infill and the build orientation have a large influence on the elastic modulus and ultimate tensile stress, whereas the layer thickness and the infill pattern have a low influence on these properties. The elongation at break...

... part, such as tensile strength, should be optimized. In this process, there are many parameters that affect the tensile strength of parts. However, the “layer thickness”, “fabrication orientation” and “post curing time” are the most significant ones. Hence, the purpose of this study is to investigate...
