A fused deposition modeling method was used in this research to investigate the possibility of improving mechanical properties poly(lactic acid) by changing thermal conditions printing process. Sample models were prepared while varying a wide range parameters, including bed temperature, melt and raster angle. Certain samples also thermally treated annealing. The materials subjected detailed thermomechanical analysis (differential scanning calorimetry, dynamic analysis, heat deflection...
The research presented in this article discusses the subject of poly(lactic acid) (PLA) modification via reactive mixing with poly(butylene adipate-co-terephthalate) (PBAT) copolymer for 3D printing applications. Filaments suitable fused deposition modeling were prepared from blends PLA containing 10, 20, and 30% by weight PBAT. Mechanical testing clearly indicated that blending PBAT effectively increases impact strength PLA, an initial value approximately 30 J/m to more than 700 optimized...
The polymer foil industry is one of the leading producers plastic waste. development new recycling methods for packaging products biggest demands in today’s engineering. subject this research was melt processing multilayered PET-based waste with PETG copolymer. resulting blends were intended additive manufacturing using fused deposition modeling (FDM) method. In order to improve properties developed materials, compounding procedure conducted addition a reactive chain extender (CE) and...
Application of lignocellulosic fillers in the manufacturing wood polymer composites (WPCs) is a very popular trend research, however it still rarely observed case rotational molding. The present study aimed to analyze impact wheat bran content (from 2.5 wt.% 20 wt.%) on performance rotationally-molded based linear low-density polyethylene (LLDPE) matrix. Microscopic structure (scanning electron microscopy), as well physico-mechanical (density, porosity, tensile performance, hardness, rebound...
The research work carried out so far indicates the ever wider possibilities and demand for shaping composite products in rotational molding technology. This trend was main reason to use waste-based filler from metallurgical process as a manufacturing polylactide (PLA)-based remolded composites. Copper slag (CS) introduced single-step processing method PLA matrix at 5, 10, 20, 35 wt%. rotomolded composites with different content were subjected in-depth structural analysis discussed...
