This work investigates the effects of ironing process on physical properties material extruded polylactic acid (PLA). Polylactic is an exceedingly popular biodegradable polymer commonly used in extrusion 3D printing. As a promising alternative to petroleum based polymers, PLA has found use medical, textile, and packaging industries due its biocompatibility, renewability, good mechanical propert...

Guided-bone regeneration (GBR) is increasingly using three-dimensional (3D) printing by fused deposition modeling (FDM) to build the filaments used for treatment. Polylactic acid (PLA) and beta-tricalcium phosphate (?-TCP) are widely as base materials in 3D printing, necessitating that they studied together context of GBR This study sought test compare properties efficacy different ratios ?-TCP...

Additive manufacturing offers a great potential for the production of objects with tailor-made inner structure especially in combination material development field polymer compounds. However, design possibilities depend on printing resolution, accuracy, and reproducibility. The quality small filigree printed by additive processes materials like fused filament fabrication (FFF) depends itself as...

Abstract This paper assesses the modifications in properties of rotomolded polyethylene (PE) and polylactic acid (PLA) composites obtained with 5 10% giant reed fibers, mainly focusing on alterations due to a bio-disintegration process. Thermal (melting temperature crystallinity degree), morphology (via optical scanning electron microscopy), chemical changes (by Fourier Transformed Infrared spe...

This study aims to determine the compression strength of Fused Deposition Material (FDM) additive manufacturing with parameters in different layer thicknesses between 0.10 – 0.35 mm. The specimen process refers ASTM D695 Standards ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid) materials. Based on test results, highest is found 0.15 mm thickness material a yield value 66.78 MPa....

Due to the lack of appropriate scaffolds, the in vitro engineering of cartilage tissue with a sophisticated structure, such as a human ear, remains a great challenge. Although polyglycolic acid (PGA) has become one of the most successful scaffolds for cartilage regeneration, how to overcome its limitations in achieving desirable mechanical strength and accurate control over shape remains an uns...

Polylactic acid (PLA) is expected to be widely used in green power equipment manufacturing due its good mechanical properties and biodegradability. In this paper, the effects of MgO with different particle sizes mass fractions on thermal electrical PLA composites were studied. The experiment found that increase fractions, conductivity MgO/PLA showed a rising trend, which was up 165.4% higher th...
