This work evaluated the impact of PEF on the structure, properties, and functionality of wheat and cassava starches focusing on 3D printing application. Aqueous starch suspensions were PEF-treated using three different combinations of field strength and total specific energy input (T1:15 kV/cm;25 kJ/kg; T2:25 kV/cm;25 kJ/kg; and T3:25 kV/cm;50 kJ/k...

The elution of unpolymerized (co-)monomers and additives from methacrylic resin-based materials like polymethyl methacrylate (PMMA) can cause adverse side effects, such as mutagenicity, teratogenicity, genotoxicity, cytotoxicity and estrogenic activity. The aim of this study was to quantify the release and the cytotoxicity of residual (co-)monomers...

This study systematically investigates the hardened properties, durability and void distribution of large-scale 3D printed cement-based materials (3DPC). Experimental results indicate that 3DPC has higher compressive and flexural strengths, lower drying shrinkage, better resistance against sulfate attack and carbonation than mold-cast cement-based ...

COVID-19 disease caused by the SARS-CoV-2 virus has had serious adverse effects globally in 2020 which are foreseen to extend in 2021, as well. The most important of these effects was exceeding the capacity of the healthcare infrastructures, and the related inability to meet the need for various medical equipment especially within the first months ...

Porosity is a feature that can be designed into 3D printed parts, notably surgical implants, and porosity is associated with improved biocompatibility and osseointegration. It is imperative to evaluate the electrochemical behavior of 3D printed-porous Ti to identify the optimum porosity with low corrosion kinetics for biomedical applications. The o...

The aim of this paper is to determine the shape of a fixed-bed reactor which maxi- mizes the conversion rate under the constraints of process model equations (i.e. conti- nuity, Navier-Stokes, and mass balance equations), energy dissipation, iso-volume, and manufacturing. Incompressible fluid, laminar flow regime and steady-state conditions in the ...

The COVID-19 pandemic has disrupted the supply chain for personal protective equipment (PPE) for medical professionals, including N95-type respiratory protective masks. To address this shortage, many have looked to the agility and accessibility of additive manufacturing (AM) systems to provide a democratized, decentralized solution to producing res...

Developing new materials for additive manufacturing (AM) technologies is an important topic, usually targeting cost reduction or better physical properties, or both. This research aims to evaluate the mechanical properties and thermal stability of a non-commercial basic photosensitive acrylic material by the addition of organophilic clays. The orga...
