selective laser sintering - Swedish translation – Linguee

In laser sin- tering, a laser beam scans the ink structure with either the beam or the substrate platform moving. Two laser types, continuous-wave and pulsed lasers, have been success- fully used to sinter Ag nanoparticle ink. [13] The advan- tages of laser sintering over traditional oven sintering are DMLS means laser-sintering using a metal powder, in which metal parts are produced directly in the building process. The basic principle of the Direct Metal Laser Sintering (DMLS) Technology is to melt down thin layers (20 ÷ 60 µm) of Metal Powder with an electronically driven LASER beam (200W). The build begins with dispensing a thin layer of metal powder onto the build platform.

Therefore – unlike SLA or Polyjet, support structures are not needed. Laser sintering takes a comparatively long time. Direct metal laser sintering (DMLS) is an additive metal printing technology that builds metal parts from a CAD file by selectively fusing stainless steel or aluminum powder into thin layers. Direct metal laser sintering’s layer-by-layer printing allows multiple parts to be combined during the printing process. 2019-09-03 · Today, we will focus on Laser Powder Bed Fusion (LPBF), which, as its name suggests, uses a laser to additively manufacture a metal part. In 1994, EOS patented its process called Direct Metal Laser Sintering (DMLS), while in 1995 the Fraunhofer Institute introduced the term SLM for Selective Laser Melting.

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.

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. Suitable for metal prototypes and functional, end-use parts, and for reducing metal volume in the component.

The Printing Process of DMLS Explained. To create your 3D print, a laser in the printer melts the powder together. So  Aug 12, 2016 The process of selective laser sintering (SLS) involves selective heating and fusion of powdered material using a moving laser beam.

Indirect Fabrication of Lattice Metals with Thin Sections Using

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). Recently, Farsoon's Application team joined hands with industrial partners to begin developing an advanced process to produce pure copper additive components using Farsoon's metal laser sintering systems. One of the parts resulting from these collaborations was a pure copper heat exchanger with complex spiral geometry and a wall thickness of only 0.5 mm. The laser sintering (LS) process uses a laser source to provide thermal energy and selectively fuse together particles of a powder material into complex three- dimensional shapes in a layer-by-layer strategy.
