Selective laser melting is one of the laser powder bed fusion technologies. It is a laser-based 3D printing technology in which metallic powder materials are selectively melted layer by layer to produce 3D objects. Since the build space is filled with an inert, i.e. inert, shielding gas such as nitrogen or argon, the metal runs little risk of
SLS vs. SLM: Print Volume Comparison. The print volumes for SLS and SLM are similar since the two AM methods are nearly identical. SLS printers can have print volumes up to 550 x 550 x 750 mm while SLM printers can have volumes up to 350 x 350 x 350 mm. There isn''t a substantial difference in print volume between the two.
What is SLM 3D printing? Selective laser melting is a powder bed fusion additive manufacturing method which uses a high power density laser to melt metal powders. The material is fused selectively according to a 3D CAD-model, and a three-dimensional homogeneous part is built layer by layer.

SLM (Selective Laser Melting) is in an additive manufacturing method specially developed for 3D Printing metal alloys. It creates parts additively by fusing metal powder particles together in a full melting process. Unlike DMLS, SLM fully melts the powder, and therefore it needs to reach a higher temperature than this other metal 3D printing

SLM (Selective Laser Melting) and EBM (Electron Beam Melting) are powder bed-fusion 3D printing technologies. A high-energy beam is used to fuse metal powder layer by layer to ultimately print a solid component. SLM has better accuracy and resolution than EBM. EBM, on the other hand, can print faster when compared to single

Metal powder is spread across the build plate in very thin layers by the coater blade. High power laser fuses a 2D slice of the part by melting the powder material via the 3D printer''s topology optimization algorithms. Build plat drops down to the next height of layer and repeats the process and spread another layer of powder material.
Selective Laser Melting (SLM) is an industrial 3D printing process that uses similar technology to SLS. But unlike SLS, it creates parts additively by sintering fine metal powder particles. A high-power laser melts and fuses the metal powder into solid surfaces. One major difference with SLM technology is the sintering temperature.
Selective Laser Melting for Serial Production. Increased productivity is crucial for production-oriented machines, and the SLM ® 500 is available with two or four lasers operating independently or in parallel.

Selective laser melting (SLM) is one of the most commonly used metallic component 3D printing techniques. In a previous investigation of multiple materials SLM reported by The University of Manchester, high porosities and cracks were found in the regions where the powder was deposited via an ultrasonic powder dispenser.

The types of applications most suited to the selective laser melting process are complex geometries and structures with thin walls and hidden voids or channels on the one hand or low lot sizes on the other hand. Advantage can be gained when producing hybrid forms where solid and partially formed or lattice type geometries can be produced together to create a single object, such as a hip stem or acetabular cup or other orthopedic implant where osseointegration is enha
