Selective laser melting is an additive manufacturing process used to build 3D metal objects using high-power laser beams. A thin layer of powder is applied to the build platform in the first construction process step with a squeegee (or a combination of several squeegees). A laser melts the metal powder with temperatures of up to 1,250 °C in

Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS) are two metal additive manufacturing processes that belong to the powder bed fusion 3D printing family. The two technologies have a lot of similarities: both use a laser to scan and selectively fuse (or melt) the metal powder particles, bonding them together and building a part layer-by
As illustrated in Fig. 1a, the 380 W sample shows a single-scan melt pool with a Gaussian laser profile, whereas the 950 W sample shows a multi-scan melt pool with a top-hat laser profile.
SLM is a 3D printing process in which metal powder is fused by laser, creating a new object layer by layer. SLM stands for (Selective Laser Melting), which means that the laser selectively melts
The newly developed selective laser melting (SLM) additive manufacturing/3D printing (AM/3DP) technology, due to the possibility to fabricate the geometrically complex components by user-defined computer aided design (CAD) data files without tools or molds9.,
Selective Laser Melting (SLM) is a metal 3D printing method that employs a high-powered laser beam to fuse metal particles together. Unlike Selective Laser Sintering (SLS), which sinters powder particles, SLM''s complete melting results in structures that boast enhanced strength and reduced porosity.
We use selective laser melting to produce objects using various metals. These objects have a high density. The selective laser melting process results in very

Abstract— Features of 3D printing, including laser melting of metal powders, were considered in this work. The effect of laser operation mode on the structure, residual stresses, and properties of manufactured metals was reviewed. A method for choosing process parameters using single tracks as universal for all types of metal laser
Selective laser melting (SLM)-assisted 3D printing was employed to directly fabricate Ni-Fe-based permalloy magnetic shields of fiber optic gyroscopes in spacecraft. Process optimization was conducted for the quantitative analyses of the influences of laser processing parameters on the bulk density and surface roughness of
Selective laser melting (SLM), also called direct metal laser melting (DMLM), is a type of metal additive manufacturing or 3D printing. Often, the terms SLM and direct metal laser sintering (DMLS) are used interchangeably. However, the two technologies differ slightly, in that SLM melts metals while DMLS fuses or sinters metals.
SLM is a 3D printing process in which metal powder is fused by laser, creating a new object layer by layer. SLM stands for (Selective Laser Melting), which means that the laser selectively melts the metal powder only where the solid material is needed. In the end, the finished object can be removed from the powder bed.
Another method of 3D metal printing is selective laser melting (SLM), in which a high-powered laser fully melts each layer of metal powder rather than just sintering it. Selective laser melting produces printed objects that are extremely dense and strong. Currently, selective laser melting can only be used with certain metals.
Selective laser melting (SLM), also called direct metal laser melting (DMLM), is a type of metal additive manufacturing or 3D printing. Often, the terms SLM and direct metal laser sintering (DMLS)
DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting) are additive manufacturing methods to create metal parts. They create parts additively by sintering fine metal powder particles, to fuse them together locally. Like in the Selective Laser Sintering process, your metal part will be created layer by layer, according to your 3D
Selective laser melting (SLM) is the premier metal 3D printing technology revolutionizing the additive manufacture of metal parts, but how does it work, and which 3D printers do it best?
Direct Metal Laser Sintering / SLM 3D Printing Process. Firstly, the roller within the metal 3D printer spreads out a thin layer of powder in the 3D printer''s empty tank. This powder layer is spread to be the same as the height of one layer (usually 20-100 microns). The print chamber of the 3D printer is then heated up.

Advances in 3D printing of thermoplastic polymer composites and nanocomposites Arnaldo D. Valino, Rigoberto C. Advincula, in Progress in Polymer Science, 20193.4 Selective laser melting (SLM) Selective laser melting (SLM) uses a high-power-density fiber laser (ytterbium fiber laser) to melt and fuse metallic powders to form a 3-dimensional part [65].
SLS 3D printers have an average build volume of 300 x 300 x 300 mm. Larger Laser Sintering 3D printers can print up to 750 x 550 x 550 mm however. Shrinkage of the part should also be expected with SLS. This can usually be estimated at around 3-3.5%, and is mostly random. Most SLS 3D printers are accurate to around 100 microns,
