Laser powder bed fusion is also known as direct metal laser melting (DMLM), selective laser sintering (SLS) or direct metal laser sintering (DMLS). In the laser powder bed fusion (LPBF) process or selective laser melting (SLM) process, a thin powder layer is first applied on a building platform, usually metal, with a so called recoater, which consists of a blade or a roller Bei der Powder Bed Fusion (Pulverbettfusion) unterscheidet man zwischen der SLS- und der EBM-Technologie, sowie dem Selective Laser Melting-Verfahren. Hier werden Pulvermaterialien verarbeitet, so unter anderem Metallpulver verschiedener Zusammensetzungen. Zu den wichtigsten Arten der Powder Bed Fusion gehören die SLS- und die Selective Laser Melting-Technologie. Diese Verfahren werden für de Laser Powder Bed Fusion is an additive manufacturing process in which thermal energy (from a laser) selectively fuses regions of a powder bed layer by layer. The end part(s) can be extremely complex and contain features not possible with conventional subtractive manufacturing processes. Common terms used for this technology include: Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), Direct Metal Laser Melting (DMLM), Laser CUSING, and more

Selective laser melting, also known as direct metal laser melting or laser powder bed fusion, is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together. To many, SLM is considered to be a subcategory of selective laser sintering. The SLM process has the ability to fully melt the metal material into a solid three-dimensional part unlike SLS Powder bed fusion (PBF) is an additive manufacturing process and works on the same basic principle in that parts are formed through adding material rather than subtracting it through conventional forming operations such as milling The Powder Bed Fusion process includes the following commonly used printing techniques: Direct metal laser sintering (DMLS), Electron beam melting (EBM), Selective heat sintering (SHS), Selective laser melting (SLM) and Selective laser sintering (SLS). 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.

  2. Today, we will focus on Laser Powder Bed Fusion (LPBF), which, as its name suggests, uses a laser to additively manufacture a metal part. In 1994, EOS patented its process called Direct Metal Laser Sintering (DMLS), while in 1995 the Fraunhofer Institute introduced the term SLM for Selective Laser Melting
  3. Additive Manufacturing (AM) wie das Laser Powder Bed Fusion (L-PBF) kann dazu beitragen, individualisierte Bauteile zu annähernd den Kosten der Massenfertigung herzustellen. Das Fertigungsprinzip von generativen Fertigungsverfahren basiert auf dem schichtweisen Aufbau aus bspw. metallischen Pulvern

Laser Powder Bed Fusion . In laser powder bed fusion, a laser heats powdered material into parts and products. After a layer of powder has been indexed down, a new layer of powder is spread to continue the process. Ultimately, this type of powder bed fusion does not require support structures, which is what makes it unique. Without support structure, more materials are needed, which makes the. Powder bed fusion is an additive manufacturing (AM) process where an energy source, such as a laser or electron beam, is used to fuse particulate materials such as metals, ceramic or polymers together to form a three-dimensional object. Common techniques include selective laser sintering, selective laser melting, and electron beam melting. In powder bed processes, particularly for metals. Laser Powder-Bed Fusion (LPBF) is an additive manufacturing process capable of producing net and near-net shape parts directly from a digital drawing file with dimensional tolerances of less than 0.1 mm [1]. Like other AM processes, such as Directed Energy Deposition (DED) and Electron Beam Additive Manufacturing (EBAM), the thermal history of the part will determine if the component develops defects, if the resulting microstructure is uniform and acceptable, and if the residual stress.

Powder Bed Fusion (PBF) is the most mature and widely used metal additive manufacturing process. PBF, which prints metal using a laser or electron beam to melt lines in powder, is able to produce complex parts that can't be produced by conventional manufacturing. However, PBF has challenges, including high material costs; slow speeds; laborious post-processing requirements; and restrictions. Das Laser Powder Bed Fusion (LPBF) gehört zu den bekanntesten additiven Fertigungsverfahren. Bei dem Verfahren wird durch selektives Strahlschmelzen in einem Pulverbett die Querschnittfläche eines Bauteils aufgeschmolzen. Das geschieht durch ein Aneinanderreihen mehrerer Schmelzspuren in einem Mikroschweißprozess. Werden mehrere dieser Schichten miteinander verschmolzen, entsteht ein. Laser Powder Bed Fusion (LPBF) is one of the most well-known Additive Manufacturing processes. In LPBF, a laser beam selectively melts powder in a powder bed, thereby generating a cross-sectional area. A component is then built as several melting tracks are strung together in a micro-welding process. When several of these layers are fused together, a three-dimensional component is created. Overlap is the region two lasers can share on the powder bed area (Figure 1). More overlap tends to be useful in increasing productivity. Less overlap tends to be useful in making the same number of lasers cover a greater area; this is specifically useful for making larger parts

Laser powder-bed fusion additive manufacturing of metals employs high-power focused laser beams. Typically, the depth of the molten pool is controlled by conduction of heat in the underlying solid material. But, under certain conditions, the mechanism of melting can change from conduction to so-called keyhole-mode laser melting Khairallah SA, Anderson AT, Rubenchik A, King WE (2016) Laser powder-bed fusion additive manufacturing: physics of complex melt flow and formation mechanisms of pores, spatter, and denudation zones. Acta Mater 108:36-45. CAS Article Google Scholar 30. Ly S, Rubenchik AM, Khairallah SA et al (2017) Metal vapor micro-jet controls material redistribution in laser powder bed fusion additive. A two‐step machine learning approach to monitoring laser powder bed fusion (LPBF) additive manufacturing is demonstrated that enables on‐the‐fly assessments of laser track welds. First, in situ video melt pool data acquired during LPBF is labeled according to the (1) average and (2) standard deviation of individual track width and also (3) whether or not the track is continuous, measured. Laser powder bed fusion (LPBF), which applies a high-energy laser beam to melt pre-deposited metallic powder layer by layer according to the computer-aided design data, has been widely used in the preparation of many kinds of materials, such as steel, titanium, aluminum, and nickel [7]. To date, LPBF has shown great advantages and potential in the manufacture of complex parts [8,9]. In recent. 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

Metall Mater. Powder Bed Fusion technologies use a thermal source (e.g. a laser) to cause fusion between powder particles. Most Powder Bed Fusion technologies use mechanisms for applying and smoothing powder as a part is constructed, resulting in the final component being covered in powder Laser powder bed fusion of metals is a technology which makes use of a laser beam to selectively melt metal powder layer-by-layer in order to fabricate complex geometries in high performance materials. The technology is currently transforming aerospace and biomedical manufacturing and its adoption is widening into other industries as well including automotive, energy, and traditional.
