| description | This study aimed to optimize lattice structure design by changing the size of
unit cell at a constant volume. It
was observed that the changes in unit cell affected the
strength of lattice structure, posing a challenge for additive
manufacturing. To evaluate these effects, Finite Element Analysis
(FEA) was conducted by applying
static loading at one end of the surface from x, y, z-axis, and combination
of model, using Inconel 625 additive manufacturing. Furthermore,
the model was analyzed by plotting graphs of changes in
cell size to deformation and stress. The
addition of outer skin to deformation and stress behavior was
also investigated. Printed parts were manufactured
through additive manufacturing using PLA to
assess how changes in lattice size affected
overhang surface
quality. The results showed that
deformation and stress behavior were influenced by the smallest cross-sectional area and
shape of the unit cell, as shown by the relationships within lattice
structure models. The addition of
compression loads also increased deformation and stress behavior, while high outer
skin thickness reduced these parameters in lattice
model. The results from the printed part of model showed poor
surface quality, particularly on the
overhanging part. |
