  2. Selective laser melting - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_melting

    Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing , or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together.

    An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. 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.

  4. Rule-based DFM analysis for direct metal laser sintering

    en.wikipedia.org/wiki/Rule-based_DFM_analysis...

    Direct metal laser sintering (DMLS) is one type of additive manufacturing process that allows layer by layer printing of metal parts having complex geometries directly from 3D CAD data. It uses a high-energy laser to sinter powdered metal under computer control, binding the material together to create a solid structure.

    selective laser melting (SLM) or direct metal laser sintering (DMLS), selective laser sintering (SLS), fused deposition modeling (FDM), [5] [6] [7] or fused filament fabrication (FFF), while others cure liquid materials using different sophisticated technologies, such as stereolithography (SLA).

  6. 3D metal moulding - Wikipedia

    en.wikipedia.org/wiki/3D_Metal_Moulding

    Direct metal laser sintering, or DMLS, uses a laser to sinter powdered metal into a solid object in gradual layers built upon each other. Cooling channels can be printed to any shape in this process, which lessens time and waste and improves quality. [2] Selective laser melting, or SLM, completely melts the powder to form a homogeneous part ...

  7. Digital modeling and fabrication - Wikipedia

    en.wikipedia.org/wiki/Digital_modeling_and...

    Selective laser sintering uses a laser to trace out the shape of an object in a bed of finely powdered material that can be fused together by the application of heat from the laser. After one layer has been traced by a laser, the bed and partially finished part is moved out of the way, a thin layer of the powdered material is spread, and the ...
