As the developing is going on, this method can be applied in new areas. By sintering, it is easy to produce completely identical batches of parts, with very small deviation of sizes, for example, pistons and rod guides for shock absorbers production. Advantages and Disadvantages: Advantages: Ability to provide support supported building.

selective laser sintering process. 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 it together.

Selective Laser Sintering (SLS) is a type of Powder Bed Fusion (PBF) wherein a bed of powder polymer, resin or metal is targeted partially (sintering) or fully (melting) by a high-power directional heating source such as laser that result to a solidified layer of fused powder [70]. 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 2020-07-22 · Another disadvantage of a laser printer is that it is limited to a specific type of print media or paper.

We'll explain how this technology works, discuss … Selective Laser Sintering Process . First developed and patented in the mid 1980’s the Selective Laser Sintering process involves the creation by additive layer technology of physical models using a carbon dioxide laser on a bed of powdered material. “I would like to thank you and your colleagues for all your help this year…The LS large intake manifold you made for us, greatly helped Advantage of this process is faster heating for small loads, meaning less time is needed to reach the sintering temperature, less heating energy is required and there are improvements in the product properties.

Advantages, challenges, and key materials processed by selective laser sintering One of the major limitations of SLS is the poor surface finishing of the fabricated parts, which requires postprocessing procedures to improve those surfaces. SLS thus avoids any organic solvent and addresses some of the drawbacks of 3DP.
