The development of
additive manufacturing technology increased the use of scaffolds in various
industries. Porosity and material properties were greatly affected the
mechanical performance of scaffolds. This study was aimed to create different
options according to geometrical and mechanical properties to determine the scaffold’s
effective elastic modulus. For their geometric options, Beam-Mix,
Beam-Orthogonal, Beam-Square, Gyroid and Schwarz-P unit cell architectures were
modelled with porosities of 20-80%. The mechanical properties of AlSi10Mg,
CP-Ti, Ti6Al4V, 316L and CoCr materials were defined to these models and
compression tests were simulated. The effective elastic modulus values were
calculated according to Hooke’s law for each combination according to the
directional deformation obtained because of the analysis. According to the
effective elastic modulus data, it was determined by Analysis of Variance (ANOVA) that the unit
cell architectures, porosities and materials parameters had an effect of 0.91%,
81.78% and 16.93%, respectively. To correlate these parameters with each other,
the data were transferred to the MATLAB software, and equations were created
with the curve fitting method. 15 equations were obtained, and the R-square
value of these equations was greater than 0.97. By using these equations,
effective elastic modulus could be obtained without limitation according to the
two desired constant values. Owing to these ratios and equations, a production
planning with two parameters would have 5 different options for the third
parameter of the structure. These options were valid within the intermediate
values and the effective elastic modulus of the structures would be obtained
quickly and reliably.
