Overview In SLS 3D Printing Service
In the realm of SLS 3D Printing, a laser is meticulously employed to melt minute particles of plastic powder, progressively crafting a part layer by layer. Typically, the materials utilized in SLS consist of diminutive plastic bits with the ability to undergo melting. Within the SLS 3D printing procedure, the machine initiates by warming the bulk powder in the powder bed, bringing it close to the melting point without reaching it entirely. This preliminary warming phase enhances the laser's efficiency, as it only needs to elevate the temperature of specific areas to the melting point.
Subsequently, a machine uniformly distributes a fine layer of plastic powder onto a platform. Following this, the laser, guided by instructions from a computer file, goes to work by heating and fusing the powder at designated spots. The platform descends slightly to introduce a new layer of powder, and this sequence repeats until the entire 3D part is fully formed.
In simpler terms, SLS serves as a 3D printing technique employing a laser to melt tiny plastic particles, systematically building intricate 3D objects through the assistance of a specialized SLS 3D Printing machine.
