Metal Selective Laser Sintering

Considers efforts to date to produce parts by direct selective laser sintering sls of metals including post processing to improve structural integrity and or to induce a transformation.

Metal selective laser sintering.

Selective laser sintering also falls under powder bed fusion but only involves plastics whereas dmls and ebm only 3d print metals. The basics of selective laser sintering. Selective laser sintering sls is a powder bed 3d printing technology that produces highly accurate and durable parts capable of being used directly in end use low volume production. It is similar to selective laser melting.

The two are instantiations of the same concept but differ in technical details. The two are instantiations of the same concept but differ in technical details. Selective laser sintering is an additive manufacturing technique that uses a laser as the power source to sinter powdered material aiming the laser automatically at points in space defined by a 3d model binding the material together to create a solid structure. Selective laser sintering sls is a type of powder bed fusion pbf wherein a bed of powder polymer resin or metal is targeted partially sintering or fully melting by a high power directional heating source such as laser that result to a solidified layer of fused powder 70.

Direct metal laser sintering selective laser melting both dmls and ebm fall under the metal powder bed fusion umbrella but have one key difference. Sls is a newer 3d printing process that is often thought of as a cousin to the popular metal 3d printing technology direct metal laser sintering dmls. It is similar to direct metal laser sintering dmls. This laser pulses to heat up the metal powder either to just below melting point this is known as metal laser sintering or just above melting point which is known as selective laser melting.

Selective laser melting is also explained below. Provides a brief overview of the basic principles of sls machine operation and discusses materials issues affecting direct sls of metals and the resultant properties and microstructures of the parts. Selective laser sintering sls is an additive manufacturing am technique that uses a laser as the power source to sinter powdered material typically metal aiming the laser automatically at points in space defined by a 3d model binding the material together to create a solid structure. This metal sintering or melting process fuses the powder together and creates a solid form.

Sls is a relatively new technology that so far has mainly been used for rapid prototyping and for low volume produ. Selective laser sintering produce highly durable and complex geometries in production grade nylon sls methods are ideal for durable functional parts for low to mid volume production rapid prototyping and functional testing. Selective laser sintering sls is a way to build prototypes early in the design cycle or production parts in a wide variety of applications. Sls machines can print objects in a variety of materials such as plastics glass ceramics and even metal which is a related process known as direct metal laser sintering.
