Effects of Steam Sterilization and Recycling on the Mechanical and Surface Properties of 3D-Printed Biodegradable PLA and Re-PLA Materials.

The application of this modeling framework to experimental datasets derived from PLA and its derivatives demonstrated that the interaction between material type and processing parameters is highly significant in determining deformation behavior.

When the data presented in the same tables and figures were analyzed according to Re-PLA specimens, it was found that there was an initial increase in surface roughness and then a decreasing trend as the infill rate and layer thickness increased ( Table 3 , Figure 7 ).

When the deformation (ε) data presented in Table 3 , Figure 5 and Figure 6 are evaluated based on layer thickness, a clear trend is observed in PLA specimens.
