Evaluation of Mechanical Properties of ABS-like Resin for Stereolithography Versus ABS for Fused Deposition Modeling in Three-Dimensional Printing Applications for Odontology

Polymers, Год журнала: 2024, Номер 16(20), С. 2921 - 2921

Опубликована: Окт. 17, 2024

This study investigates the differences in mechanical properties between acrylonitrile butadiene styrene (ABS) samples produced using fused deposition modeling (FDM) and stereolithography (SLA) ABS filaments ABS-like resin, respectively. The central question is to determine how these distinct printing techniques affect of resin which method delivers superior performance for specific applications, particularly dental treatments. evaluation methods used this included Shore D hardness, accelerated aging, tensile testing, Izod impact flexural resistance measured by a 3-point bending test, compression testing. Poisson’s ratio was also assessed, along with microstructure characterization, density measurement, confocal microscopy, dilatometry, wettability, Fourier-transform infrared spectroscopy (FTIR), nanoindentation. It concluded that has same hardness both manufacturing methods; however, FDM process results significantly compared SLA. Microscopy demonstrates more accurate sample geometry when fabricated printable suitable applications dentistry fabricate models surgical guides SLA methods, as well facial protectors sports method.

Polymer Matrix Nanocomposites Fabricated with Copper Nanoparticles and Photopolymer Resin via Vat Photopolymerization Additive Manufacturing

Polymers, Год журнала: 2024, Номер 16(17), С. 2434 - 2434

Опубликована: Авг. 28, 2024

This investigation explores the fabrication of polymer matrix nanocomposites via additive manufacturing (AM), using a UV photopolymerization resin and copper nanoparticles (Cu-NPs) with vat 3D printing technology. The aim in this study is to investigate mentioned materials different formulations terms inexpensive processing, property related variability, targeting multifunctional applications. After AM process, samples were post-cured light order obtain better mechanical properties. particles mixed an ultrasonicator, particle contents used 0.0, 0.5, 1.0 wt %. process was simple inexpensive, as technologies are quite accessible, from printer curing device. These characterized scanning electron microscopy (SEM) observe materials’ microstructure tensile tests quantify stress–strain derived Results showed that, besides simplicity mixing effective, which observed microscope. Additionally, strength increased irradiation exposure, while strain properties did not change significantly.

Mechanical, Thermal and Morphological Study of Bio-Based PLA Composites Reinforced with Lignin-Rich Agri-Food Wastes for Their Valorization in Industry

Polymers, Год журнала: 2024, Номер 16(17), С. 2462 - 2462

Опубликована: Авг. 29, 2024

This study investigates the performance of different poly(lactic acid) (PLA) composites incorporating agri-food waste additives and commercial lignin, comparing their properties with those virgin PLA. The following were prepared using a single-screw extruder: PLA 20% rice husk, wheat straw olive pit. Additionally, was blended lignin at maximum feasible proportion same methodology. resulting injection-molded into specimens for analysis mechanical, thermal morphological behavior. primary objectives to assess dispersion within matrix evaluate mechanical composites. results indicate that addition high percentages agricultural residues does not significantly compromise Notably, in case husk composite, elastic modulus surpassed PLA, despite evident heterogeneity filler particle sizes. It incorporate higher percentage compared attributed larger volume occupied by latter.

Developing a stiffness-toughness balance, low-cost, and biodegradable PLA composite is an effective strategy for improving product market competitiveness, reducing dependence on petroleum-based resources protecting the environment. Rice husk (RH) extensively used as filler in polymers, but addition of too much rice into has damaged toughness composite. In this work, fully composites with balance low cost are successfully fabricated through melt blending PLA, RH acetyl tributyl citrate (ATBC). The results show that bio-based plasticizer ATBC can improve flowability composites, further enhancing their processability, which promotes dispersion PLA. impact strength elongation at break PLAC20 reach value 100 J/m 148%, achieving increase 4.3 60.1 times compared PLAC0, respectively. torque rheological test shows maximum equilibrium arrive 25.3 N/m 2.3 N/m, about 67.4% 63.5% lower than those PLAC0 after incorporation 18 phr ATBC, respectively, indicating significant improvement processing performance. As amount increases, water absorption rate progressively rises, while contact angle steadily diminishes, resulting hydrophilicity, thereby broadening its potential applications.
