SLS 3D Printing Services in Chennai & Coimbatore

SLS 3D Printing in Rapid 3D Technologies uses a laser to fuse particles of plastic powder together building parts layer by layer. This powder bed technology rival’s 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 (Selective Laser Sintering) 3D printing works

In Coimbatore and Chennai , Rapid 3d  Technologies Service provider  provides you a cheap SLS (Selective   Laser Sintering) 3D printing   is an additive manufacturing technology that uses a high power laser to sinter small particles of polymer powder into solid  structure based on a 3D model  at low cost with high standard quality in Rapid 3D Technologies.

Printing

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 came in a granular form.

Cooling

Cooling

After printing the build chambers needs 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.

Pre-Processing

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.

Why Choose SLS for your 3D Printing Project?

SLS is ideal to make 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 at 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

SLS capabilities

Requirement Specification
Maximum build Volume (Single Build) 340 x 340 x 600 mm
(Parts shall be split, Print separately and fused together to form much larger volumes)
Standard lead time 4-5 business days
Dimensional accuracy ± 0.2 mm
Layer height 100 μm
Finish As printed SLS parts are typically white or stone grey in color with a smooth surface and a powder texture and without visible layers

Nylon 12 (PA 12)(Polyamide )

The industry 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, 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 resistance up to 180°C

  • High Chemical Resistance

  • Excellent long-term stability

Materials

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