2 Inconel alloys are oxidation and corrosion resistant materials which are well suited for service in Direct metal laser sintering Direct metal laser sintering (DMLS) is an AM process [1] by which digital 3D design data (Fig. 1a) is used to build up a component in layers by depositing metal material. The system starts by applying a thin layer of the powder ma-terial to the building platform (Fig. 1b). After each layer, a laser beam then fuses laser sintering process. Design of experiments methodology has also been applied for metal Selective Laser Melting (SLM) in addition to Selective Laser Sintering [7].

showed a direct process on pure yttria-zirconia (Y 2 O 3-ZrO 2) powders through selective laser sintering/melting using a 1.064 μm fiber laser . The authors studied the influence from the powder and the powder bed and found the properties of particles and powder layers significantly affected the product.

After the part is left to cool, the surrounding loose metal powder is removed from the printer. selective laser sintering process. The CO2 laser is often used to sinter successive layers of powder instead of liquid resin.

These lasers are aimed at defined points, binding the material together in order to form one, solid part or component. The SLS process involves the solidification of a polymer binder material around the steel powder 2011-08-03 Optimizing selective laser sintering process by grey relational analysis and soft computing techniques Hamed Sohrabpoor1,2*, Sushant Negi3, Hamed Shaiesteh4, InamUl Ahad1,2 and Dermot Brabazon1,2 1Advanced Processing Technology Research Centre, Dublin City University, Dublin, Ireland 2 School of Mechanical & Manufacturing Engineering, Dublin City University, Dublin, Ireland Direct Metal Laser Sintering, also known as DMLS, is an industrial 3D printing 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).

This gives the powder compact enough green strength to hold together during further processing. Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), is one of the most used Additive Manufacturing technologies to produce structural plastic parts. In this article, we explain the process principle and materials used in the SLS process. November 26, 2020 by Dr. Natalie Rudolph and Milena Riedl Selective laser sintering requires a high level of precision and tight control throughout the printing process. The temperature of the powder along with the (incomplete) parts must be controlled within 2 °C during the three stages of preheating, sintering, and storing before removal to minimize warping, stresses, and heat-induced distortion. 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.
