That's what this article is all about. Selective laser melting (SLM) is a relatively new technology that is used to form metal products through the use of applying a laser beam to a powder bed.

In this paper, the selective laser melting (SLM) forming method was combined with the requirement of boiling heat transfer for porous structure to study the forming process and boiling heat transfer characteristics of porous structure of G-surface lattice formed by SLM.

A schematic layout of a typical SLM setup is presented in Fig.

The SLM 125 selective laser melting machine offers a compact build envelope designed for cost-efficient process development and small to medium lot production of high-quality, fully dense metal parts. Selective laser melting (SLM) process is a powder bed fusion technology; it uses a focused laser beam to melt consecutive layers of fine metal powder particles according to the cross-sectional profiles of a 3D computer aided design to manufacture three-dimensional components.

Selective Laser Melting technology, or SLM as it is commonly referred to, is an innovative process used to produce metal parts.

To avoid problems related to Selective Laser Melting, titanium powder was consolidated using low intensity laser light (100-300 W/cm2) for a long period of time (5 s). In a one-step process, small rod-like parts, with graded porosity, of an appropriate size for dental implants can be prepared by selective laser melting. Unlike traditional machine tooling which involves removing shavings, SLM produces metal parts by the gradual addition of successive layers of laser-melted powder.

The SLM®125 Selective Laser Melting Machine is accurate, compact metal 3D printing with low powder volume Size : 125 x 125 x 125 mm (4.9 x 4.9 x 4.9 in) Laser : 1x 400W Thereby, SLM enables the production of nearly unlimited complex geometries with-out the need of part-specific tooling or pre-production costs [4].

Selective Laser Melting is an efficient process for producing metal parts with minimal subtractive post-processing required. Selective laser melting (SLM) is one of the premier technologies, but how does it work? Ti6Al4V lattices with graded and regular porosity form suitable structures for bone cell ingrowth, with mechanical properties comparable to cancellous bone.

Selective laser melting of hypereutectic Al-Si40-powder using ultra-short laser pulses 1 3 Page 3 of 6 798 with Al 2O 3 nano-powder to obtain deeper insight into the microstructure. 2.2 SLM process parameters In SLM, there are a number of input parameters that can be controlled and varied in order to get sintered parts with optimized quality. The 400W fiber laser is the highest laser power in its class and replicates production settings with up to 80% less metal powder than other systems.

Selective laser melting uses a laser to melt successive layers of metallic powder. This allows for various material crystalline structure arrangements to be possible that might otherwise be impossible with traditional manufacturing processes. 316L stainless steel powder was used to rasterize the G-surface structure. It is relatively mature and has been a research focus in manufacturing metallic parts [6].

Analysis of the parameters controlling the part quality has been performed focussing on the energy intensity during processing and the effect of the particle size distribution on factors such as ultimate tensile strength and surface finish. To many, SLM is considered to be a subcategory of selective laser sintering (). More .
