“…Compared to flat orientation and with the same raster angle, the specimens 3D printed in on-edge orientation typically has interlayer structure with better adhesion and compaction, as more layers need to be printed. This confirmed the results of Palanisamy et al 4 and Sadeghi et al 17 For the orientation 0°elsewhere when the tensile load is perpendicular to the filament the UTS remains constant for both orientations because it corresponds to the inter filaments adhesion. The load in this case tends to separate filaments.…”

In additive manufacturing, fused deposition modelling (FDM) is one of the most often-used technologies. Polylactic Acid (PLA) is the most frequently applied polymer for prototyping or for real uses. This study mainly focuses on the mechanical properties of PLA parts printed with filament exposed to UV light to mimic the effect of recycled filament. Three radiation periods were studied, respectively, 24 h, 48 h and 72 h. Tensile tests were carried out to characterize the influence of building orientation (On flat/on-edge) and raster angles (0°, 45°, 90°, 0°/90°, −45°/+45°). Failure modes were also discussed. Printed specimens were subjected to water absorption to assess the mechanical properties in real application. Generally with the same raster angle, the interlayer structure of specimens manufactured in on-edge orientation has greater adhesion than the specimens in flat orientation. The results show that mechanical properties are lower in case of flat building orientation and the raster angle has the same trend in both orientations. Elsewhere, edge orientation exhibited lower water absorption thanks to the inwall that protected the printed part. UV radiation enhances the interface between printed layers for the lower period. The mechanical properties were affected by the degradation of the bulk material in the direction of 90°.

“…However, studies mentioned in Table 1 use standard tensile test specimens that are much larger than individual elements of the hexagonal lattice structure. Furthermore, the properties of the polymer material are not fixed and depend on production settings, i.e., the layer thickness or the specimen building orientation [ 27 ] and likely the size of the specimen. The Stratasys reports Young’s modulus ranging from 1000 MPa to 2000 MPa.…”

The study aims to compare mechanical properties of polymer and metal honeycomb lattice structures between a computational model and an experiment. Specimens with regular honeycomb lattice structures made of Stratasys Vero PureWhite polymer were produced using PolyJet technology while identical specimens from stainless steel 316L and titanium alloy Ti6Al4V were produced by laser powder bed fusion. These structures were tested in tension at quasi-static rates of strain, and their effective Young’s modulus was determined. Analytical models and finite element models were used to predict effective Young’s modulus of the honeycomb structure from the properties of bulk materials. It was shown, that the stiffness of metal honeycomb lattice structure produced by laser powder bed fusion could be predicted with high accuracy by the finite element model. Analytical models slightly overestimate global stiffness but may be used as the first approximation. However, in the case of polymer material, both analytical and FEM modeling significantly overestimate material stiffness. The results indicate that computer modeling could be used with high accuracy to predict the mechanical properties of lattice structures produced from metal powder by laser melting.

“…For some printers with a high degree of autonomy, additional parameters include print speed, nozzle temperature, chamber temperature, plate temperature, cooling fan speed, and so on. Previous researchers have investigated the effect of some printing parameters on the mechanical properties of 3D-printed parts [ 6 , 7 , 8 ]. For the application of powered ankle-foot prostheses, the 3D-printed frame parts are mainly used to support the user’s weight.…”

Effect of Infill Parameters on the Compressive Strength of 3D-Printed Nylon-Based Material

3D printing is the most suitable method to manufacture the frame parts of powered ankle-foot prostheses but the compressive strength of the 3D-printed part needs to be ensured. According to the compression test standard ASTM D695, the effect of infill pattern and density, which is transferred to the mass of the standard specimen, on the compressive strength is investigated with a carbon fiber-reinforced nylon material. With the same infill pattern, specimens with more mass have a higher compressive strength. With the same mass, specimens with triangular fill have a higher compressive strength than those with rectangular and gyroid fills. Compared with specimens with a solid fill, specimens with a triangular fill can also provide more compressive strength in a unit mass. According to the results of standard specimens, following the requirement of strength and lightweight, 41% triangular fill is selected to manufacture the supporting part of a powered ankle-foot prosthesis. Under a compressive load of 1225 N, the strain of the assembly of the standard adaptor and the 3D-printed part is 1.32 ± 0.04%, which can meet the requirement of the design. This study can provide evidence for other 3D-printed applications with the requirement of compressive strength.
