Functionality Versus Sustainability for PLA in MEX 3D Printing: The Impact of Generic Process Control Factors on Flexural Response and Energy Efficiency

Polymers, Journal Year: 2023, Volume and Issue: 15(5), P. 1232 - 1232

Published: Feb. 28, 2023

Process sustainability vs. mechanical strength is a strong market-driven claim in Material Extrusion (MEX) Additive Manufacturing (AM). Especially for the most popular polymer, Polylactic Acid (PLA), concurrent achievement of these opposing goals may become puzzle, especially since MEX 3D-printing offers variety process parameters. Herein, multi-objective optimization material deployment, 3D printing flexural response, and energy consumption AM with PLA introduced. To evaluate impact important generic device-independent control parameters on responses, Robust Design theory was employed. Raster Deposition Angle (RDA), Layer Thickness (LT), Infill Density (ID), Nozzle Temperature (NT), Bed (BT), Printing Speed (PS) were selected to compile five-level orthogonal array. A total 25 experimental runs five specimen replicas each accumulated 135 experiments. Analysis variances reduced quadratic regression models (RQRM) used decompose parameter responses. The ID, RDA, LT ranked first time, weight, strength, consumption, respectively. RQRM predictive experimentally validated hold significant technological merit, proper adjustment per case.
