This study introduces novel PETG–ABS–Fe3O4 nanocomposites that offer impressive 3D- and 4D-printing capabilities. These can be remotely stimulated through the application of a temperature-induced magnetic field. A direct granule-based FDM printer equipped with pneumatic system to control output melt flow is utilized print composites. addresses challenges associated using high weight percentage nanoparticles lack over geometry when producing precise continuous filaments. SEM results showed interface matrix was smooth uniform, increase in weakened printed layers. The ultimate tensile strength (UTS) increased from 25.98 MPa for pure PETG–ABS sample 26.3 27.05 10% 15% Fe3O4 nanocomposites, respectively. accompanied by decrease elongation 15.15% 13.94% 12.78%. shape-memory performance reveal adding iron oxide not only enables indirect remote recovery but also improves effect. Improving heat transfer strengthening elastic component rate amount shape recovery. Nanocomposites containing 20% demonstrate superior subjected stimulation field, despite exhibiting low quality poor strength.

The article presents the results of technical-economical study regarding optimization fused deposition modeling (FDM) parameters (the height layer deposited in one pass-Lh and filling percentage-Id) for manufacture Polyethylene Terephthalate Glycol (PETG) Acrylonitrile Styrene Acrylate (ASA) parts. To carry out this study, was used fundamental principle value analysis, which consists maximizing ratio between Vi Cp, where represents mechanical characteristic, Cp production cost. show that tensile specimens made PETG, parameter significantly influences Vi/Cp ratios is pass, (Lh), case compression percentage (Id). In manufactured via FDM from ASA, decisively By performing process with multiple responses, we identified optimal manufacturing parts PETG ASA: Lh = 0.20 mm, percentage, Id 100%.

ABSTRACT Novel shape memory thermoplastic vulcanizates (TPVs) based on polylactic acid (PLA) and chloroprene rubber (CR) have been fabricated via a dicumyl peroxide (DCP)‐induced dynamic vulcanization process. In situ, melt reactive compatibilization was achieved by molecular grafting of PLA onto the CR chains. This evidenced ATR‐FT‐IR spectroscopy, swelling test, mechanical thermal analysis (DMTA) results. Field emission scanning electron microscopy revealed co‐continuous morphology for dynamically vulcanized PLA/CR blends even at 70/30 phase ratio compared to unvulcanized counterpart samples. novel microstructure surprisingly indicated network with excellent performance fixity close 100% high recovery ~90% pure PLA. Furthermore, vulcanizate displayed significantly improved tensile impact strength in comparison blends, which are attributed both blend chemically cross‐linked nature The DMTA results illustrated higher elastic modulus TPVs as result their unique microstructure.
