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.

Thin-Walled Part Properties in Powder Bed Fusion of Polymers—A Comparative Study on Temperature Development and Part Performance Depending on Part Thickness and Orientation

Journal of Manufacturing and Materials Processing, 2023
To develop new areas of application for laser-based powder bed fusion of polymers (PBF-LB/P), a deeper process understanding of the resulting mechanical properties, particularly for thin-walled and complex structures, is needed.

Optimizing directed energy deposition of polymers through melt pool temperature control: impact on physical properties of polyamide 12 parts

Progress in Additive Manufacturing
The method of Directed Energy Deposition of polymers (DED-LB/P) was extended to allow control over the melt pool temperature using a pyrometer. DED-LB/P was used to build test specimen of polyamide 12 (PA12), orthogonal and parallel to the long side ...

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Influence of the Origin of Polyamide 12 Powder on the Laser Sintering Process and Laser Sintered Parts

Applied Sciences, 2017
Different features of polymer powders influence the process of laser sintering (LS) and the properties of LS-parts to a great extent. This study investigates important aspects of the “powder/process/part”-property relationships by comparing two polyamide
