Selective Laser Sintering (SLS) is one of the most popular polymer 3D printing technologies for industrial applications. Since its emergence more than 30 years ago, SLS has been gradually maturing into a technology capable of functional prototyping and, more recently, also production.

What is SLA manufacturing?

Stereolithography (SLA) is an additive manufacturing process that can 3D print parts with small features, tight tolerance requirements, and smooth surface finishes.

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 is sintering in 3D printing?

Sintering is the process of applying heat and/or pressure to fuse bits of metal, ceramic, and other materials into a solid mass.

What powder is used in selective laser sintering?

Nylon 12 is the most popular general use powder for SLS 3D printing that offers versatility and enables a broad range of applications. Nylon 12 GF is a glass-filled composite material with enhanced stiffness and thermal stability for demanding industrial environments.

What materials are used for SLS and FDM parts?

SLS or Selective Laser Sintering is known to be the most common 3D printing technology that is used for industrial applications. Its main material is nylon/polyamide in powdered form. This is a process which uses high powered laser to fuse together small particles of the material.

What material can be used in a 3D printer?

Plastic is still the most popular material used for 3D printing. As the 3D-printing market value increases, the list of what materials can be used also grows. Raw materials such as metal, graphite, and carbon fiber are commonly used for 3D printing, though at-home use is mostly limited to PLA for now.

What materials can be used in an FDM printer?

  • Polylactic acid (PLA): Find PLA materials.
  • Acrylonitrile butadiene styrene (ABS): Find ABS materials.
  • Polyethylene terephthalate (PET): Find PET materials.
  • Thermoplastic polyurethane (TPU): Find TPU materials.
  • Poly-ether-ketone (PEEK): Find PEEK materials.

Which of the following materials can be printed in an FDM machine?

The most common printing material for FDM is acrylonitrile butadiene styrene (ABS), a common thermoplastic that’s used to make many consumer products, from LEGO bricks to whitewater canoes. Along with ABS, some FDM machines also print in other thermoplastics, like polycarbonate (PC) or polyetherimide (PEI).

Is SLS nylon strong?

SLS 3D printed nylon parts are strong, stiff, sturdy, and durable. The final parts are impact-resistant and can endure repeated wear and tear. Nylon is resistant to UV, light, heat, moisture, solvents, temperature, and water.

Does SLS use laser?

The SLS 3D printer uses a laser as a energy source which selectively melts powdered plastic material, fusing them together into a 3D printed part. This technology is part of Laser Powder Bed Fusion (LPBF), one of the most advanced and reliable technologies in the 3D printing field of additive manufacturing.

Titanium is 3D printed using the DMLS (Direct Metal Laser Sintering) or SLM process. A very fine metal powder is melted with a laser to produce your design layer by layer. Once your design is complete any support structures are removed and any finishing completed. Unused powder is recycled for use on the next model.
