Imagine a bed of fine powder, meticulously heated to just below its melting point. Now, picture a powerful laser, selectively tracing the contours of your design within this powder bed. As the laser passes, it fuses the powder particles together, solidifying a thin layer of your 3D object. This process, known as Selective Laser Sintering (SLS), repeats layer by layer, gradually building your design like a digital sculptor shaping a masterpiece from sand.

With each pass of the laser, the unfused powder remains in place, acting as a support structure and eliminating the need for additional supports. Hollow shapes and dense, three-dimensional grid patterns can be formed easily and with minimal post-processing. Once the printing is complete, the excess powder is brushed away, revealing a fully formed, highly durable product.
