Received: 18 February 2024; Published: 22 August 2024; doi: 10.21926/rpm.2403020

Abstract

This study investigates the influence of thermal environmental conditions during printing and their effects on the mechanical properties of material extrusion (MEX) 3D-printed 17-4 PH stainless steel. Various ambient temperatures and cooling behaviors were used during the printing process of the tensile specimens. Following DIN EN ISO 50125 and DIN EN ISO 6892, the study analyzes tensile strength, elongation and yield strength. The results demonstrate that the thermal environmental conditions af [...]

Received: 15 April 2024; Published: 09 August 2024; doi: 10.21926/rpm.2403019

Abstract

This paper describes a method to use solely recycled and by-product materials as constituents to form concrete that can be used in buildings structural applications. As concrete is one of the most important materials in human civilization, where it is used widely in construction, cement and aggregate the main components of concrete cause an emission of large amounts of carbon dioxide, which is the main cause of global warming. The production of one tonne of cement, for example, cause [...]

Abstract

To develop a modular anthropomorphic phantom to evaluate the performance of radiological techniques for detecting pathologies in the temporal bone region. A phantom was constructed using a human skull, temporal bone specimen, and 3D-printed contour of a human skull. The human skull was embedded in tissue-equivalent plastic, with a cavity to hold the plastic jars containing the exchangeable freshly frozen human temporal bones. Subsequently, stepwise introduction and examination of different clini [...]
