Abstract Experiments and finite element (FE) calculations were performed to study the raster angle–dependent fracture behaviour of acrylonitrile butadiene styrene (ABS) thermoplastic processed via fused filament fabrication (FFF) additive manufacturing (AM). The properties 3D-printed ABS characterized based on concept essential work (EWF), utilizing double-edge-notched tension (DENT) specimens ...

The most common additive manufacturing technique fused filament fabrication (FFF) suffers from inter-bead porosity that reduces mechanical properties. Inter-bead pores follow the raster angle, which causes anisotropic Yet, effects of angle on behavior short-carbon-fiber-reinforced (SCFR) thermoplastics are unclear. In this study, we performed tensile, flexural, and fracture toughness tests SCFR...

Polymer materials produced by additive manufacturing undergo significant changes in their dimensions under continuous loading conditions. This situation affects the operation of polymer structures within safe limits. Therefore, it is crucial to determine creep behaviour polymers method. study investigates six different materials, acrylonitrile butadiene styrene (ABS), chlorinated polyethylene (...

Electroforming on additively manufactured templates has the potential to become a manufacturing process for making complex metal parts in flexible and economical way. However, main challenge of electroforming is high surface roughness when deposition thickness increases (thickness ​> ​100 ​μm), due current density edges co-deposition impurities while electroforming. In this work, hybrid electro...

The article attempts to determine the best working conditions for desktop 3D printers with printing chamber. For analysis, polymer materials acrylonitrile-butadiene-styrene (ABS) and polylactide (PLA) as two most commonly used copolymers in printing. work presents types of filaments compares them terms shrinkage, which is a disadvantageous phenomenon occurs especially prints made higher tempera...

Microbial contamination of plastic surfaces is a significant source hospital-acquired infections. To produce antimicrobial surfaces, chlorhexidine was attached to nitrided acrylonitrile butadiene styrene (ABS). The uniformity distribution on the revealed by time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging. Its efficacy established against model pathogenic Gram-positive and Gram...

This paper presents the design of a small size Unmanned Aerial Vehicle (UAV) using 3DEXPERIENCE software. The process designing frame parts involves many methods to ensure can meet requirements while conforming safety and industry standards. steps start with selection materials that be used for drone, which are polylactic acid (PLA), acrylonitrile styrene acrylate (ASA), butadiene (ABS). drone ...
