Selective laser melting (SLM) is a part of additive manufacturing where a high-power-density laser is used to melt and fuse metallic powders together. This is a fast developing process that is being implemented in both research and industry. Selective Laser Melting is also known as direct melt laser melting or laser bed fusion.

Laser Sintering process introduction and identification of its Feb 3, 2016 Selective Laser Sintering (SLS) is an additive manufacturing process that uses a laser to fuse powdered starting materials into solid 3D Dec 15, 2016 Working Process. SLM works on the principle of melting. The working is same as SLS where as the power is melted instead of sintering. Melting Sep 23, 2014 There are essentially two types of laser sintering processes: selective laser sintering (SLS) and direct metal laser sintering (DMLS) (note: these Nov 18, 2013 Additive manufacturing process creates highly complex metal parts for many industries DMLS systems work by directing a laser beam into May 5, 2015 Aerospace Materials, Direct Metal laser sintering (DMLS) Rapid prototyping, SLS. I. INTRODUCTION. Additive manufacturing processes have Feb 18, 2014 But what sets sintering apart from melting or "Cusing" is that the sintering processes do not fully melt the powder, but heat it to the point that the Feb 1, 2012 An Open Source Laser Sintering 3D Printer and limits the possible shapes of the model in ways that the additive SLS process does not.

Laser sintering process

Both Selective Laser Sintering and Direct Metal Laser Sintering is widely used within the industry today. Used for, among other reasons, rapid prototype casting, these alternative methods of sintering offer its own set of functionality and advantages. Selective Laser Sintering (SLS) is a form of additive manufacturing technology under the powder bed fusion technique category. SLS is primarily associated with printing plastic parts and components.

The Sintering Process: Initial Stage The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures.

[19] and Wauthle et al. [20] employed SLS/SLM to process implants for medical purposes while Vasquez et al. [21] recently developed new SLS materials for snowboarding applications. during the sintering process. In terms of the signature of acoustic signals, two phases can be roughly separated, i.e. internal laser sintering (0– 10.1 s) and boundary laser sintering (10.1–11s).

The manufacturing process is fully automated and computer controlled, following the computer-aided design (CAD) data of the processed geometry. Selective laser sintering is an additive manufacturing technique that uses a laser as the power source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to selective laser melting; the two are instantiations of the same concept but differ in technical details. SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume produ The Selective Laser Sintering process involves tiny particles of polymer powders material being fused together via heat from a high power laser. A thermal source is used to fuse the powder particles together at a specific location on the build platform to develop a solid, 3D printed part. The laser heats the powder either to just below its boiling point (sintering) or above its boiling point (melting), which fuses the particles in the powder together into a solid form.

But people continue to call this process DMLS (Direct Metal Laser Sintering). 25 years ago it was indeed sintering, as the founder of EOS invented it. The laser power wasn’t very high so the particles merely sintered together and then you had to run the parts through a Hot Isostatic Press (HIP) secondary process to try and reduce the voids. Direct metal laser sintering (DMLS) is an industrial metal 3D printing process that builds fully functional metal prototypes and production parts in 7 days or less. A range of metals produce final parts that can be used for end-use applications.

At first, discrete particles remain because complete compaction or melting does not occur.
