Less than half of e-waste plastics are sorted worldwide, and this rate is likely to decline as major processing countries have banned importation plastics. This forces the development decentralized facilities, also known microfactories. The present work investigates recyclability different grades acrylonitrile-butadiene-styrene (ABS) copolymer, polycarbonate, polypropylene, which were found be ...

Pellet additive manufacturing (PAM) is in terms of printing process very similar to the widely used fused deposition modelling (FDM) systems. The main difference use pellets instead filament. In this study, a pellet, single screw extruder developed. A design with variable pitch and depth modelled analytically predict melting behavior acrylonitrile butadiene styrene (ABS) during steady state ext...

Poly(lactic acid) (PLA) is a “green” alternative to petroleum-based plastics and desirable choice for many applications. However, low heat deflection temperature lack of toughness, together with the slow crystallization kinetic neat PLA hinder its widespread application. The weak properties can be improved improvement crystallinity, which depends on molecular weight, D-lactide content, presence...

This study aimed to construct three-dimensional (3D) anatomical models of the tongue domestic mammals veterinary interest. The tongues were obtained from didactic collection Laboratory Veterinary Macroscopic Anatomy in Surgery Department School Medicine and Animal Science, University Sao Paulo. Tongues a cow, dog, horse, pig selected for scanning creation 3D-printed models. printer used filamen...

This paper presents experimental values for the coefficient of restitution (en) millimeter-sized ice particles colliding with massive walls at different temperatures. Three wall materials are tested: hardened glass, and Acrylonitrile butadiene styrene (ABS) polymer. The results show a high sensitivity to impact velocity Vi, where en decreases rapidly increasing Vi. also decrease in temperature ...

<p>Acrylonitrile Butadiene Styrene (ABS) polymer is an example of a thermoplastic that requires heat in its production process. ABS also can be modified to increase strength against resistance, toughness, and resistance by adding MCC as reinforcement composites. Extrusion one the established methods processing with filler consequently disperses inside polymer. Different speed shows differ...

The most abundant e-waste plastic is acrylonitrile butadiene styrene (ABS), which not typically processed by municipal programs and equally one of the popular 3-D printing filaments. This makes ABS a prime candidate for distributed recycling additive manufacturing (DRAM) approach, has potential to increase rates providing economic incentive consumers recycle. For DRAM be globally applicable, th...

The production of conductive and organic devices from a 3D printer represents promising strategy for several areas. In particular, the synthesis polypyrrole-coated acrylonitrile butadiene styrene (ABS) composites can be considered an important step to produce supports printing. Herein, it is reported ABS samples through additive manufacturing process (3D printing) accordingly Fused Deposition M...

Three-dimensional printing can bring huge advantages when fabricating difficult structures and components in industry. This technology is also used commonly for threaded fasteners the engineering field. The main disadvantage of threated self-loosening. In this study, an International Organization Standardization (ISO) standard M12 × 1.75 bolt nut were printed by using a 3D printer three types m...
