The Comprehensive Guide to Laser Powder Bed Fusion Additive
Understanding and optimizing process parameters are crucial for achieving high-quality parts in Laser Powder Bed Fusion (LPBF). This section will discuss the impact of laser characteristics, powder properties, layer thickness, and strategies for process optimization.
Laser Powder Bed Fusion
Laser Powder Bed Fusion (L-PBF) is a technique in which a layer of metal powder is deposited, melted, and solidified using a laser to create a solid layer of metal, with consecutive 2D layers being joined to preceding layers to build up fully solid 3D components.

Powder bed fusion (PBF) methods use either a laser or electron beam to melt and fuse material powder together. Electron beam melting (EBM), methods require a vacuum but can be used with metals and alloys in the creation of functional parts.
Laser Powder Bed Fusion—Principles, Challenges, and
Laser Powder Bed Fusion (L-PBF) is an additive manufacturing process which uses a scanning laser beam to selectively melt metal powder in a layer-wise manner to produce solid metal parts.
Powder Bed Fusion, How does it work? | Dassault Systèmes®
Powder Bed Fusion (PBF) 3D printing technology spawns products with precision. This 3D printing technique enables manufacturing a vast array of geometrically complex products using a heat source, mainly laser or electron beams, to fuse powder particles layer-by-layer, forming a solid part.
Laser powder bed fusion: a state-of-the-art review of the
LPBF is one of the powder bed fusion methods where a powder bed is spread, and pre-determined regions are exposed to high-intensity laser energy. That way, powders can be melted and fused layer-by-layer in compliance with the design prepared in the CAD software.
Laser Powder Bed Fusion
Laser powder bed fusion (LPBF) has gained the most attention from academia and industry among metal powder–based additive manufacturing techniques. This chapter focuses on the LPBF technique, regarding its history, fundamentals, printing process, metallurgical defects, powder materials, equipment, and the microstructures
Powder bed fusion processes: An overview
This chapter summarizes the recent research in the laser-based powder bed fusion process. It covers the characteristics of the process and melt pool; microstructural features including texture, residual stress and defects; and characteristics of mechanical properties of metallic parts processed by the laser-based powder bed
Powder Bed Fusion: The Working Process, Current Applications
Powder bed fusion (PBF) includes three main processes; (1) selective laser sintering, (2) direct metal laser sintering and (3) selective laser melting where a three-dimensional (3D) object can be printed in a layer-by-layer method from employing a powder bed and a laser (Fig. 5.1).
What is Powder Bed Fusion 3D Printing? | Additive Manufacturing
Powder bed fusion (PBF) is a 3D printing method that joins powdered material point by point using an energy source, typically a laser beam or an electron beam. Powder bed fusion is one of the most common 3D printing techniques used for industrial additive manufacturing (AM).
