2. Selective laser sintering - Wikipedia

   en.wikipedia.org/wiki/Selective_laser_sintering

   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.

3. Powder bed and inkjet head 3D printing - Wikipedia

   en.wikipedia.org/wiki/Powder_bed_and_inkjet_head...

   A 3D selfie in 1:20 scale printed by Shapeways using gypsum-based printing, created by Madurodam miniature park from 2D pictures taken at its Fantasitron photo booth. In the original implementations, starch and gypsum plaster fill the powder bed, the liquid "binder" being mostly water to activate the plaster.

4. 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.

5. 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.

6. 3D metal moulding - Wikipedia

   en.wikipedia.org/wiki/3D_Metal_Moulding

   There are multiple methods used in 3D metal printing. Selective laser sintering, or SLS, uses heat from a powerful laser to fuse tiny ceramic, glass or plastic particles together, forming a 3D part. Carl Deckard and Joe Beaman of the University of Texas developed and patented the process in the 1980s.

7. Sintering - Wikipedia

   en.wikipedia.org/wiki/Sintering

   A commonly used second external force is pressure. Sintering performed by only heating is generally termed "pressureless sintering", which is possible with graded metal-ceramic composites, utilising a nanoparticle sintering aid and bulk molding technology. A variant used for 3D shapes is called hot isostatic pressing.
