SLS 3D Printing Services in Chennai & Coimbatore

Rapid 3D’s SLS 3D printing technique fuses plastic powder particles 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 3D printing is a powder bed fusion 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 each layer, a re-coater deposits fresh powder, and the build platform moves down by one layer height. This SLS 3D printing process repeats until the parts are fully complete.

How does SLS 3D printing works

In Coimbatore and Chennai, a Rapid 3D service provider offers cost-effective SLS 3D printing services . This additive manufacturing technology 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.

Printing

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

Cooling

After printing, the build chambers need to cool down inside the print enclosure slightly 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.

SLS 3D Printing Materials

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

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

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
Maximum wall thickness	20 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 printing is ideal for making functional parts that have greater toughness and higher impact strength than parts produced through other 3D Printing methods.
