Selective Laser Sintering or SLS 3d printing is a laser technology that fuses powder materials of plastic, glass, ceramic, and a range of different material powders by heating, rather than melting, to print a hardened three-dimensional object.

Unlike other printing technologies, SLS 3D printing service doesn't require any supports to hold the printed objects or protect from falling during printing. This also saves material costs as the parts stay in the bed of powder. It is most useful for engineers in product development because of cost-effective and faster functional prototyping and production. Besides cost, SLS rapid prototyping process also saves time required for sanding after the object is printed.

SLS technology is among the most popular 3D printing technologies for industrial and engineering applications. It is used to produce functional parts and prototypes from various materials, including metals, plastics, composites, and ceramics. Selective Laser Sintering printers use laser beams to selectively fuse powdered material, layer by layer, to create a three-dimensional object. The resulting component is solid and does not require any support structure.

Selective laser sintering is used for a wide range of products, including aerospace components, automotive parts, medical implants, consumer goods and sporting equipment. It is also being increasingly used for rapid prototyping in product development.

SLS 3D Printing Service
Selective Laser Sintering ( SLS )


SLS rapid prototyping is used for printing three-dimensional objects in different materials. It can print any complex designs, functional parts, living hinges, and interlocking parts. It is popularly used for creating prototypes and for final production. Industries that need high-quality parts in a small quantity such as airplane parts, hearing aids, prosthetics, and dental retainers usually prefer this process.

It is widely used in industries like:

  • Aerospace: SLS additive manufacturing printing is helpful in the aerospace industry because it can produce high-quality parts with complex designs. It can also print living hinges and interlocking parts necessary for aeroplanes and other aerospace vehicles.
  • Dental: In dentistry, SLS printing creates dental retainers and other orthodontic appliances. These parts need to be precise and durable, and SLS printing is the perfect process for making them.
  • Prosthetics: SLS printing is also used to create prosthetic devices. These devices need to be both strong and lightweight, and SLS printing can meet both of these requirements.
  • Hearing Aids: Hearing aids are another standard prosthetic device, and SLS printing is often used to create them. The small size and delicate components of hearing aids require a high level of precision, which SLS printing can provide.


SLS 3D Printing process starts by converting a CAD file into .STL format for easy interpretation and rendering by SLS machines.

1. A thin layer of powder is spread out on the top of a platform inside the build chamber of SLS machine

2. The laser is then directed to the platform tracing a cross-section of the 3D CAD model to heat the powder exactly at or below the melting point. This fuses the tiny particles together to form a solid object.

3.The platform in the build chamber is lowered by one layer and the printing material is dispersed by a recoater on it. Then, the next cross-section is traced by the laser to fuse the tiny particles.

4.When all the layers are completed, the final product is left for cooling inside the printer
