Article Synopsis
- The paper focuses on optimizing FDM (Fused Deposition Modeling) parameters, specifically layer height (L) and infill density percentage (I), for creating tensile and compression samples from recycled PETG and ASA materials.
- The study employs value analysis to balance mechanical strength and production cost, revealing that layer height primarily affects tensile samples made from rPETG, while infill density is crucial for rASA samples.
- Ultimately, the research identifies optimal FDM settings (L = 0.20 mm and I = 100%) for producing parts from recycled materials, supporting circular economy practices in manufacturing.
The article presents the results of the technical-economical study regarding the optimization of fused deposition modeling (FDM) parameters (the height of the layer deposited in one pass-L and the filling percentage-I) for the manufacture of Polyethylene Terephthalate Glycol (PETG) and Acrylonitrile Styrene Acrylate (ASA) parts. To carry out this technical-economical study, was used the fundamental principle of value analysis, which consists of maximizing the ratio between and , where represents the mechanical characteristic, and represents the production cost. The results of the study show that for tensile specimens made of PETG, the parameter that significantly influences the results of the / ratios is the height of the layer deposited in one pass, (L), and in the case of the compression specimens made of PETG, the parameter that significantly influences the results of the / ratios is filling percentage (I).
