Thermal, morphological, and mechanical properties of three-dimensional (3D) printed polylactic acid (PLA) composites reinforced with different amounts waste pine sawdust were investigated. To determine the obtained filaments, test samples produced using a 3D printer according to standards. The filaments that from blends contained wood at highest level (20%) could be via without any problems. Ac...

Abstract Additive manufacturing or 3D-Printing technology is being utilized heavily in recent times, especially a range of industries. Many types and sizes 3D-printers are producing ceramic, metal, plastic components. This serving society many aspects, such as minimizing environmental impact, reduction cost, even material consumption. Polylactic acid (PLA) thermoplastic filament type used Fused...

Plasticizers are commonly used plastic additives. Deep understanding of their effect on the migration other substances is essential, especially for food contact materials. The kinetics four stabilizer-type additives from polypropylene (PP) and polylactic acid (PLA) with different tributyl acetyl citrate plasticizer content were investigated. results confirm that presence in plastics enhances sw...

Abstract The aim of this study was to determine the rheological property and crystallization behavior polylactic acid (PLA) with improved heat resistance (Ingeo™ Biopolymer 4032D) through investigation melt viscosity kinetics PLA at different process temperatures. measured using a rotational rheometer under conditions shear rates 0.01, 0.1, 1/s. obtained data show that tended decrease slightly ...

Most widespread materials in Additive Manufacturing are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene), which dissimilar terms of printing abilities mechanical properties. material originates from renewable resources making it better solution for environment comparison with petroleum-based material. Addition second-phase particles to polymer matrix may have a substantial influe...

Luffa reinforced polylactic acid (PLA) bio-composites were prepared and examined. The luffa surface was treated using three chemicals, i.e., sodium hydroxide, 3-aminopropyltriethoxysilane, acetic anhydride, which enhanced compatibility with PLA. Mechanical testing done on the chemically modified PLA bio-composites, tensile, flexural, hardness, thermal. Infrared spectral functional group morphol...
