Laser Powder Bed Fusion of CuSn10 : A Review

Engineering Reports
ABSTRACT This review examines the current state of CuSn10 alloy manufacturing using Laser Powder Bed Fusion. Through a systematic literature search, 32 articles on LPBF‐processed CuSn10 are identified and evaluated. This provides an overview of processing parameters, microstructures, mechanical properties, corrosion behavior, the ...

The effect of inter- and intra-layer delay time on TPU parts fabricated by laser powder bed fusion

In polymer laser powder bed fusion (PBF-LB-P) techniques, such as laser sintering, the time between scanning a given point in one layer and the same x-y point in the next layer is known as the ‘inter-layer delay time’.

Mechanism of microstructure and mechanical properties improvement through ultrasonic rolling pressing layer-by-layer and adaptive ultrasonic rolling method research in AlSi10Mg laser powder bed fused

Journal of Materials Research and Technology
In the process of laser powder bed fusion (L-PBF), the high-speed movement of the laser heat source causes uneven temperature and stress fields, thus, it results in dendrites, pores, micro cracks and residual stresses.

Effect of Layer Thickness and Scanning Parameters on Melt Pool Geometry and Track Continuity in Powder-Bed Arc Additive Manufacturing

Metals
Powder-bed arc additive manufacturing (PBAAM) may reduce the cost of powder-bed metal additive manufacturing and enable thicker layers than laser powder bed fusion (LPBF), but melt-track stability limits are not well established.

Thermo‐Optical Analysis of Surface‐ and Volume‐Additivated Polymer Powders for Near‐Infrared Laser Powder Bed Fusion

Advanced Photonics Research
Near‐infrared laser sources have the potential to change the process dynamics in laser powder bed fusion of polymers. To take full advantage of the shorter processing laser wavelength, the addition of absorbing additives, such as carbon black ...

Local Remelting in Laser Powder Bed Fusion

Journal of Manufacturing and Materials Processing
In Laser Powder Bed Fusion, process material defects such as a lack of fusion, powder inclusions and cavities occur repeatedly by chance. These stochastically distributed defects can significantly reduce the mechanical performance of the components ...

Powder characterisation techniques and effects of powder characteristics on part properties in powder-bed fusion processes

Virtual and Physical Prototyping, 2017
Powder-bed fusion is a class of Additive Manufacturing (AM) processes that bond successive layers of powder to facilitate the creation of parts with complex geometries. As AM technology transitions from the fabrication of prototypes to end-use parts, the
