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 …

Great for creating geometrically complex parts where much customization is required. DMLS is a great alternative when other manufacturing methods simply cannot create parts with certain geometries. advantage: 1) can be directly produced metal parts (unique). 2) a wide selection of materials. 3) can be manufactured complex components or molds. 4) no additional base support.

selective laser sintering (SLS), fused deposition modeling, and inkjet printing1--- have emerged and almost overtaken stereolithography in terms of fre- quency of

The CO2 laser is often used to sinter successive layers of powder instead of liquid resin. Parts are built upon a platform which sits just below the surface in a bin of the heat-fusible powder. A beam of laser then traces the pattern on the very first layer thereby sintering … The existing systems that are available for reconstruction are (1) converts minutiae template to skeleton image and then to grayscale, (2) reconstructs grayscale image directly from minutiae. The disadvantages with the above existing systems are spurious minutiae and partial fingerprint construction.

The materials used in SLS are thermoplastic polymers that come in … Advantages and Disadvantages: Advantages: Ability to provide support supported building. The unsintered powder surrounding the part in the build cylinder acts as a natural support for the next layer. No elaborate supports need to be built such as in some photo polymer systems. Laser sintering has a wider range of applications because this technology is well established and offers a large choice of materials and sizes.

Selective Laser Sintering (SLS) is definitely an Additive Manufacturing (AM) technique that utilizes a selective laser sintering advantages and disadvantages. 28 Oct 2016 Unfortunately, the advantages of laser melt additive manufacturing are sometimes nullified by the disadvantages. Due to slurry formation, highly 22 Jan 2020 Selective Laser Sintering awakened the scientist's interest since SLS has its own advantages and disadvantages for pharmaceuticals. 24 Mar 2019 The History of SLS SLS refers to selective laser sintering, which was developed in the mid-1980s by Dr. Carl Deckard and Dr. Joe Beaman. Much Advantages: Can manufacture parts in standard metals with high density A wide can be further processed Disadvantages: The technology is costly Tolerances Advantages and disadvantages of Laser Metal Deposition technology.

The advantages of SLS. SLS has been one of the go-to methods for rapid prototyping, especially for batch production of custom parts. In industrial-scale applications, it is a reliable, precise, and fast method that has stood the test of time. 1. No need for support structures.
