“The fused deposition modeling (FDM) form of additive manufacturing provides a low-cost opportunity to quickly create unique parts with complex geometries using a high degree of precision. This is accomplished through a layer-by-layer extrusion of a metallic infused thermoplastic from a heated nozzle onto a build plate, until the 3D part is achieved. The ability […]

“In this study, a simple and low-cost approach to additively manufacture (3D print) Inconel 718 by using a desktop fused filament fabrication (FFF) 3D printer via a 3-step printing-debinding-sintering stage is presented. Inconel 718 filament containing high metal loading (86% by mass) was 3D printed by varying the nozzle temperatures from 210°C to 300°C. As-printed

“Despite the significant research being conducted on the mechanical reliability of additively manufactured parts, comparatively little focus has been paid to the property of thermal conductivity. Additively manufactured thermally conductive parts have the potential to benefit thermal management technologies that are currently a bottleneck of many classes of advanced electronic devices. Creating parts with high thermal conductivities remains

“As additive manufacturing gains widespread adoption across various industries, its application to traditional materials such as bronze remains relatively underexplored. Through a comprehensive assessment, this research investigates the extrusion-based additive manufacturing of bronze, utilizing a CuSn10/Polylactic Acid (PLA) composite filament for printing bronze green parts, followed by thermal debinding and sintering processes to produce metal parts. By systematically varying 3D printing, debinding,

“This work evaluates the radiation shielding capabilities of the PLA-W composite for MV energy photons emitted by a linear accelerator and the feasibility of manufacturing a clinically-used collimator grid in spatially fractionated radiotherapy (SFRT) using the material extrusion (MEX) 3D printing technique. The PLA-W filament used has a W concentration of 93% w/w and a green density

“To lower the cost of additive manufacturing of metallic components, the goal of this work is to investigate and optimize a multi-step process by material extrusion (MEX) of a polylactide filament loaded with bronze to remove the gas produced during the debinding and sintering steps. First, by adjusting the infill (10%, 50%, and 100%), and
