3D Printed Parts with Honeycomb Internal Pattern by Fused Deposition Modelling; Experimental Characterization and Production Optimization

摘要: In the present study additive manufacturing of Polylactic acid by fused deposition modeling were investigated based on statistical analysis. The honeycomb internal pattern was employed to build inside specimens due its remarkable capability resist mechanical loads. Simplify 3D utilized slice model and adjust fixed parameters. Layer thickness, infill percentage, extruder temperature considered as controlled variables, while maximum failure load (N), elongation at break (mm), part weight (g), time (min) selected output responses analysed response surface method. Analysis variance results identified layer thickness major variable for all responses. Interaction percentage had a significant influence therefore, tough fracture printed parts. input parameters optimized materialize tow criteria; first one rise second attain lessen time. Optimal solutions examined experimental fabrication evaluate efficiency optimization There good agreement between empirical method predictions which confirmed reliability predictive models. optimal setting fulfill criterion could bring specimen with more than 1500 (N) less 9 (g) weight.
