Abstract Scope |
Recent advancements in Additive Manufacturing, particularly in Material Extrusion (MEX), have focused on lightweight (LW) PLA filaments. This study explores the thermal and mechanical properties of LW-PLA filaments to optimize the strength-to-weight ratio. Foaming additives, activated thermally to induce expansion, have been introduced to PLA. Three LW-PLA filaments are tested to assess their lightweighting capabilities. Using Thermogravimetric Analysis and Differential Scanning Calorimetry, degradation and glass transition temperatures are determined. Taguchi design is employed to analyze tensile strength, considering parameters like print orientation, nozzle diameter, and printing temperature. Initial findings suggest expanded LW-PLA exhibits decreased strength. The type of LW-PLA and print orientation significantly influence tensile strength, whereas nozzle diameter and printing temperature have minimal impact. Various weight-reduction settings are explored to identify the optimal strength-to-weight ratio. This research enhances understanding of LW-PLA properties and advances applications of MEX through strength-to-weight ratio optimization. |
