What is selective laser sintering used for?
Selective laser sintering enables engineers to prototype parts early in the design cycle, then use the same machine and material to produce end-use parts.
What are the materials used in SLS?
Commercially-available materials used in SLS come in powder form and include, but are not limited to, polymers such as polyamides (PA), polystyrenes (PS), thermoplastic elastomers (TPE), and polyaryletherketones (PAEK).
What type of materials is used in SLM machine?
SLM Solutions’ IN939 is a highly alloyed material containing amounts of chromium, cobalt, titanium, tungsten, aluminum, tantalum, and niobium. Owing to IN939’s high temperature mechanical properties, the alloy is widely used in turbine component construction.
What material is used in Lom?
Laminated object manufacturing (LOM) is a rapid prototyping system originally developed by Helisys Inc. LOM technology uses adhesive-coated paper, plastic, or metal laminates as a 3D printing medium. These sheets of material are glued together layer-by-layer and cut into shape using a knife or with laser cutting.
What are the advantages of SLM?
5.5. 3 Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS)
| Advantages | Disadvantages |
|---|---|
| Very strong, very tough metal parts | Relatively new technology |
| Accurate | Very high cost of machine and materials |
| Materials can be sterilised easily (using autoclave) | Inert gas supply required |
| Wide range of metal materials |
What is SLS material?
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Which material is used in SLA process?
SLA 3D printers use light-reactive thermoset materials called “resin.” When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.
Which material is not used in LOM process?
| Q. | Which material is NOT available for LOM process? |
|---|---|
| B. | Plastic |
| C. | Metal |
| D. | Glass |
| Answer» d. Glass |
Which material is used in FDM technology?
FDM utilizes strong, engineering-grade materials like ABS, Polycarbonate and ULTEM™ 9085 Resin. FDM can create production parts and functional prototypes with outstanding thermal and chemical resistance and excellent strength-to-weight ratios.
What’s the difference between SLS and SLM?
What is the difference between SLS vs SLM? SLS atomically fuses powdered industrial materials together using a high-powered laser; SLM fuses powdered materials together by heating them until they reach a melting point. Sintering temperatures typically run at about 85% of a material’s melting point.
What are the advantages and disadvantages of selective laser sintering?
Advantages & Disadvantages of SLS In A Nutshell

Working Process. SLM works on the principle of melting. Process Variations. Some SLM industries are works with some other material like magnesium for light weight construction. Processing materials. The normal materials used in SLM are stainless steel, aluminium or titanium alloys. Design aspects. Quality aspects. Economical aspects.
How does selective laser sintering (SLS) work?
– high overhanging angles (0 to 45 degrees from the horizontal plane) – complex geometries embedded deep into parts, such as conformal cooling channels – batch production of multiple parts produced in 3D arrays, a process called nesting
What is selective laser?
Selective laser sintering is an additive manufacturing technology that sinters small particles of polymer powder into a 3D three-dimensional structure through high-power laser light; thus, this is also called selective laser sintering 3D printing, or SLS 3D printing.
What is selective laser melting?
Steel and iron-based alloys
