Ironing is a useful feature for parts made by fused filament fabrication (FFF), as it can smooth out surfaces using heat and extruding small amount of material. Like any other processing parameter FFF, ironing also requires optimisation to ensure surface be achieved with limited adverse effects on the features printed part. Even such beneficial use case, still considered experimental and, there...

Abstract Materials and articles made of acrylonitrile–butadiene–styrene (ABS) intended for contact with food must comply the requirements European Plastic Regulation (EU) 10/2011, which lays down simulants time/temperature conditions to be applied migration testing. Previous studies indicated that high concentrations ethanol at temperatures above ambient may lead swelling ABS polymers resulting...

Abstract Owing to the deposition mechanism, parts fabricated from material extrusion (ME) process have intrinsic air gaps that negatively impact their mechanical properties. Thus, amount of should be minimized. In this study, a warm isostatic press (WIP) was adopted decrease gaps, resulting in improved properties using acrylonitrile butadiene styrene (ABS). To identify changes properties, tensi...

In this work, the effect of mixing temperature (Tmix) on the mechanical, rheological, and morphological properties of rubber/cyclic butylene terephthalate (CBT) oligomer compounds was studied. Apolar (styrene butadiene rubber, SBR) and polar (acrylonitrile butadiene rubber, NBR) rubbers were modified by CBT (20 phr) for reinforcement and viscosity reduction. The mechanical properties were deter...

Morphology formation during compounding, as well as injection molding of blends containing 60 wt % polycarbonate (PC) and 40 wt % polybutadiene rubber-modified styrene-acrylonitrile copolymers (ABS), has been investigated by transmission electron microscopy (TEM). Profiles of the blend morphology have been recorded in injection-molded specimens and significant morphology gradients observed betw...

A series of drop weight tests were conducted to evaluate the dynamic flatwise compression strength and flexural strength of sandwich panels with a novel core structure. This sandwich core material, known as Norcore, consists of interconnected cells in a unique configuration of truncated pyramid with sloping cell walls. Core materials made of thermoplastic including virgin Lexan, polycarbonate, ...

Applying thin metallic coating layers on the surface of polymeric parts or structures (metallization) that is generally performed via electroplating process aims to improve both mechanical integrity and design aesthetics. The electroplated parts, which greatly controlled by strong interfacial adhesion between metal polymer, can be measured using standardized tests, such as tape test peel test, ...

This study is the first to demonstrate how mechanical and geometrical properties of polylactide (PLA) acrylonitrile butadiene styrene (ABS) additively manufactured with material extrusion can be selectively tailored using a newly devised treatment method chemical immersion in acetone. combination manufacturing results hybrid process capable modifying behaviour predictable time-controlled manner...

The aim of the present study was to investigate effects fiber content and then silane treatment on mechanical performance natural composites recycled acrylonitrile–butadiene–styrene (ABS) provided by automotive sector. Wood palmyra fibers were used as fillers in 10% 20% composites. treated with N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane improve interfacial adhesion between polymer matrices....
