Surface quality and absorption properties of Polymeric Composite (PLA-PCU) fabricated using 3D printing for articular cartilage application
The objective of this study is to investigate the impact of four 3D printing process parameters (i.e., layer thickness, PCU composition, nozzle speed and extruding temperature) on the surface roughness and absorption rate of the mixture of PolyLactic Acid (PLA) and PolyCarbonate Urethane (PCU)....

| Summary: | The objective of this study is to investigate the impact of
four 3D printing process parameters (i.e., layer thickness,
PCU composition, nozzle speed and extruding
temperature) on the surface roughness and absorption
rate of the mixture of PolyLactic Acid (PLA) and
PolyCarbonate Urethane (PCU). The specimen was
printed using a Fused Filament Fabrication (FFF)
technology. The response surface methodology was used
for analysing all the experimental data and developing an
effective empirical prediction model. The results of the
study indicated that the generated model was not much
significant with regards to absorption rate, while it was
very significant for the surface roughness response
parameter. A detailed analysis of the results indicated that
layer thickness was the most significant factor that
affected the surface roughness, while PCU composition
affected the absorption rate. The optimal surface
roughness (2.5400 µm) and absorption rate (0.0470%) of
the printing process parameters was obtained when PCU
concentration is 10 wt.%, layer thickness 0.1 mm, nozzle
speed 15 mm/s and extruding temperature 195℃. |
