Optimization of selective laser sintering process conditions using stable sintering region approach
eXPRESS Polymer Letters, 2021 The optimization of process parameters represents one of the major drawbacks of selective laser sintering (SLS) technology since it is largely empirical and based on performing a series of trial-and-error builds.

Development of a radiopaque dental glass for endodontic laser applications
Journal of Materials Research and Technology, 2020 The aim of this study was to develop a laser-sinterable and radiopaque glass powder as a potential sealer in endodontic therapy. The hypothesis was that it is possible to dope a SiO2-Na2O-CaO-P2O5–based glass with barium (Ba) and tantalum (Ta) in such a ...

Study on densification of laser ignited reaction sintering of Ni-Al-Cu powder [PDF]
Science of Sintering, 2007 The mechanisms of densification during laser ignited reaction sintering of Ni-Al-Cu powder materials were studied. With the addition of Cu, densification of Ni-Al-Cu specimens made of big particles was realized under laser rapid ignition and sintering ...

Embedding Components During Laser Sintering
Additive Manufacturing Letters, 2022 We propose an approach for embedding electronic components during a Selective Laser Sintering (SLS) process. Common SLS processes are incompatible with component embedding because generating voids in the parts developed using this production method is logistically challenging.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions
Advanced Engineering Materials, EarlyView.This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.
