Abstract
This study examines the Markforged simulation software's efficacy in predicting properties of Markforged 3D-printed parts. Material extrusion (MEX) is widely used across industries for its ability to create intricate shapes with diverse internal patterns. To evaluate mechanical properties, especially due to varying infill patterns, the Markforged simulation tool is employed. Tensile test specimens based on ASTM D-638 were 3D printed using a Markforged Mark Two printer and "Onyx" material, varying layer thickness, infill pattern, and density. Deformation is simulated under a 500 N tensile load and compares to physical tests on a tensile machine, considering different pulling speeds. Results show minimal variation between simulations of solid infill patterns and experiments, regardless of speed. However, porous infill patterns exhibited notable differences. Tensile testing also revealed the impact of pulling speed on deflection for "Onyx" specimens under a 500 N load.
