Abstract

The application of selective laser sintering (SLS) across various industries is limited by the narrow range of available polymers. It is essential to develop new materials for SLS using sustainable methods. In this study, poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) composite powders with great flowability were prepared in different ratios using thermally induced phase separation (TIPS). The particle size, morphology, and wide sintering window of the PLA/PBAT composite powders demonstrated their suitability for SLS. Optimized process parameters enabled the successful manufacturing of various specimens via SLS. Tensile tests revealed that the addition of PBAT improved the mechanical properties of the composite, with 3.5 wt% PBAT yielding the best results. PLA/PBAT composite powders produced via this environmentally friendly method were shown to be viable for use in SLS.

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
