direct metal laser sintering process

Laser Sintering Technology. Laser sintering process was first introduced by Deckard and Beaman [].Laser sintering is also referred to as "3D printing" because it builds up framework in a series of successively thin layers (0.02–0.06 mm) [].A high powered laser beam is focused onto a bed of powdered metal and these areas fuse into a thin

1. Introduction. Direct Metal Laser Sintering is an additive manufacturing (AM) technique that uses a laser fired into a metal powder bed to create a solid structure through a layer-by-layer sintering process [1], [2], [3].DMLS allows the production of complex metallic structures with complex internal and external features.

Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that uses a high-power laser to fuse metal powder particles layer by layer to create a solid, three-dimensional object. The laser selectively melts the metal powder according to a digital design, and the build platform lowers incrementally to allow for the addition of new

CL50WS material has been mainly used in tooling industries for making die, tool insert, mould or casting die. As the manufacturing of the CL50WS material parts from the DMLS machine differs from the conventional machining process, it is very essential to understand of DMLS behaviour and determine the proper optimal process parameter.

The most popular way to 3D print metal parts is metal sintering, a powder bed fusion technology that''s more accessible than ever. Learn why!

The fuel source (electron shaft, laser, curve, etc.) for these frameworks is given. The powder bed framework can be beneficially arranged in specific laser sintering, particularly laser softening, direct metal laser sintering, and electron shaft liquefying. In this examination, a direct metal laser sintering measure was picked [7].

Nevertheless, the surface finishing of parts made of this material is rougher than other materials used by the DMLS process, making optimal part orientation and machine settings even more important to

Direct metal laser sintering process defects. Direct metal laser sintering (DMLS) process is a type of metal AM processes (ISO.ASTM 52900:2015), where high power laser is used to scan and melt the metal material in order to build parts in a layer-by-layer manner (Ning et al. 2019a).

Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material. In this process, laser automatically aims at points in space defined by a three-dimensional (3D) model, binding the material together through sintering process to create a solid structure.1 An important

Abstract. An iron based powder blend has been developed for rapid tooling using a direct laser sintering process. The powder consists of a mixture of different elements including Fe, C, Cu, Mo and Ni. High sintering activities were obtained by tailoring the powder characteristics and optimizing the chemical constituents.

The numerical method used in the simulation of Direct Metal Laser Sintering process is a thermo-mechanical transient phenomenon, which is a multi-physics coupled model. This is a weakly coupled model, which means the thermal history determines the mechanical response, while the mechanical response can be assumed to have little

Direct laser metal sintering (DMLS), which is classified among powder bed fusion additive manufacturing [], was introduced in 1995 [] and is also defined by several other proprietary names as selective laser sintering (SLS), selective laser melting (SLM), and direct metal laser melting (DMLM) stead of conventional subtractive

The direct metal laser sintering process involves six basic steps: Step 1 – The DMLS process begins by slicing the 3D design CAD file data into single extremely thin layers, generating a 2D model for each layer. Step 2 – The machine uses a high-powered optic laser, inside the build chamber area that contains inert gas.
