3.3.3 Laser powder bed fusion. Laser powder bed fusion uses a laser to selectively melt metal powders in a powder bed (Fig. 5 (c)). This process involves spreading a thin layer of metal powders on the build platform and then melting it using a focused laser [109]. The non-melted powders of the powder bed serve as support for the manufactured parts.
Powder bed fusion process is one of the basic technique associated with additive manufacturing. It follows the basic principle of manufacturing the product layer by layer and their fusion. Similar to SLS, it is a layer by layer process with computer controlled laser technique. Basically, the machine produces the object on a movable

We utilize machine learning (ML) methods in a case study on laser powder bed fusion (LPBF) of a Zr-based glass-forming alloy. Our experiments show that processing parameters affect density and amorphicity opposingly, demonstrating the efficacy of our ML-based approach. We employ multi-objective optimization using Gaussian Process
A computer-aided design (CAD) model was developed from pictures and measurements of the machine. The computer model includes the geometry of the build chamber (best seen in Fig. 1(b)), the nozzles, the outlet, the recoater blade, the powder bed, the build area, and the tubing behind the build chamber (best seen in Fig. 1(c)).The
Powder bed fusion, like other 3D printing processes, "The QLS 230 printers give us the ability to use end-of-life powder from other SLS and MJF machines to produce high-quality parts while eliminating powder waste. On top of the operational sustainability, the smaller build volume of the QLS 230 allows for a much shorter build
Like FDM manufacturing technology, powder bed fusion (PBF) is a well-known manufacturing technique that is remarkably used in the aerospace, automobile, biomedical, construction, and composite industries (Chueh et al., 2020 ). This technology was first invented in 1971 by P. A. Ciraud and modified in 1994 by C. Deckard ( Chatham et al.,
Powder bed fusion is an additive manufacturing technology which creates a 3D part one layer at a time using a fine powder as the print medium. This powder is sintered or melted with either a laser or an electron beam as the heat source. Sintering and melting result in different outcomes but both are types of powder bed fusion metal printing.
