SLS 3D Printing Services in Chennai

SLS 3D Printing Services in Chennai & Coimbatore

Rapid 3D’s SLS 3D printing technique fuses plastic powder particles together with a laser to build parts layer by layer. This powder bed technology rivals injection moulding strength and mechanical properties for short production runs of parts. SLS technology in 3D Printing Services has hardly any printing limitations, giving freedom to design and print complex geometries.

SLS is a powder bed fusion 3D printing technology. It uses a CO2 laser to fuse tiny bits of nylon powder, tracing the geometry of digitally sliced CAD models layer by layer, after which a re-coater deposits a new layer of powder and the build platform moves down one layer in height. The process is then repeated until the parts are complete.

How does SLS 3D printing works

In Coimbatore and Chennai, a Rapid 3D service provider offers cost-effective SLS 3D printing, an additive manufacturing technology that utilizes a high-powered laser to fuse tiny polymer powder particles into a solid structure based on a 3D model. This process delivers high-quality results at an affordable price.



In SLS 3D Printing, a laser selectively sinters particles of a polymer powder, fusing them together and building a part layer by layer.  The materials used in SLS 3D printing are thermoplastic polymers that come in a granular form.

SLS Cooling


After printing, the build chambers need to slightly cool down inside the print enclosure and then outside the printer to ensure optimal mechanical properties and avoid warping in parts. This can take a significant amount of time.

Post processing

The finished parts need to be removed from the build chamber, separated, and cleaned of excess powder. The powder can be recycled, and the printed parts can be further post-processed by media blasting or media tumbling.


The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production.

Best SLS 3d Printing in Chennai

Nylon 12 (PA 12)(Polyamide )

Nylon 12 is a leading material for industrial 3D printing. This robust material has superb mechanical properties and can replace injection moulded alternatives.

  •  High strength and stiffness
  • Fully functional, high-quality plastic parts
  • Excellent mechanical properties, an ideal substitute for common injection moulding plastics
  • High abrasion resistance, ideal for use in the development of parts with movable components
  • Excellent long-term stability

Glass-filled Nylon(PA 12 GF)(Polyamide)

Glass-filled SLS nylon is reinforced with glass beads, creating parts with higher stiffness and thermal stability than standard nylon.

  • High strength and stiffness
  • Temperature tolerance of up to 180°C
  • High Chemical Resistance
  • Excellent long-term stability

Design guidelines for SLS

The table below summarizes the recommended and technically feasible values for the most common features encountered in 3D printed parts.

Feature Recommended size
Unsupported walls 1.0 – 2.0 mm
Supported walls 0.8 – 1.0 mm
Minimum feature size 1.0 mm (living hinges are possible at 0.7 mm)
Minimum hole diameter 1.0 mm

Thicker parts must be hollowed with and at least two escape holes for powder removal with a min. diameter of 8 mm

Why Choose SLS for your 3D Printing Project?

SLS is ideal for making functional parts that have greater toughness and higher impact strength than parts produced through other 3D Printing methods.

High Accuracy

On-demand SLS 3D printing enables you to prototype your product using industrial quality materials. Prototype matches the production, Form Fit & Functions can be easily realized

Functional Parts

Strong and durable, SLS Nylon produces best in class working properties that can either be flexible or rigid depending on the geometry of the design

Low Volume Production

SLS is a viable production method for manufacturing parts in volume. This technology can be used as an alternative to injection moulding. Key benefits include no costs for tooling or alterations.

Applications of SLS (Selective Laser Sintering) 3D printing

  • Prototypes with good mechanical properties similar to injection-moulded parts

  • Small parts in limited volume

  • Functional prototyping or large production parts in taxing environments

  • Light weight designs
