Towards a Process for Synthesising Affective Surface Textures

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 … 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. The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures. At first, discrete particles remain because complete compaction or melting does not occur.

Additiv tillverkning – från protoyp till produktion

Selective Laser Sintering Additive Manufacturing Technology is a unique and comprehensive guide to this emerging technology. It covers in detail the equipment, software algorithms and control systems, material preparations and process technology, precision control, simulation analysis, and provides examples of applications of selective laser Another method is indirect sintering or two-step sintering, where the laser treatment creates only a preliminary porous structure, which afterwards is sintered again with a heat treatment.

The process will be repeated until the desired part is created. Compared to other additive manufacturing processes such as stereolithography (SLA) and Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF), Selective Laser Sintering (SLS) does not require support structures since the powder acts as self supporting material. Selective laser sintering fabricates complex plastic parts and assemblies in a single process, one layer at a time. Step 1 The first step in the process is to upload the CAD (computer-aided design) model of the part to the selective laser sintering machine. The machine uses the CAD model to slice the design into thousands of horizontal layers. Laser Sintering Laser sintering was done on an in-house refurbished EOSINT M250 machine. The machine was equipped with a 60 W continuous wave CO 2 laser and a peristaltic pump for slurry deposition.

(Image credit: Materialgeeza/Creative Commons) Additive manufacturing, or 3D printing, is the process of turning digital designs into Selective laser sintering was one of the first additive manufacturing techniques, developed in the mid-1980s by Dr. Carl Deckard and Dr. Joe Beaman at the University of Texas at Austin. Their method has since been adapted to work with a range of materials, including plastics, metals, glass, ceramics, and various composite material powders. Selective laser sintering or melting. There are different ways to carry out additive manufacturing but one of the most popular is a method known as the selective laser sintering process or melting. In selective laser sintering (SLS), the process used by UTHSCSA/UTA, components are built by material addition rather than by material removal by using a directed laser beam that causes individual particles to fuse in selected regions of space. The process begins by ﬁrst depositing a thin layer of powder into a container. 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.
