SLS Printing

Selective Laser Sintering (SLS)  is a  powder  based  technique wherein each layer is  accurately fused together by a laser. 

It  is a highly precise 3D printing process that cost-effectively produces industrial strength parts, complicated geometry, detailed visual and robust functional prototypes.

Low Volume Production

Versatile

How SLS Production  Works  

Selective Laser Sintering  (SLS) builds a part layer-by-layer via a laser fusing nylon-based powder together.  

  1. 3D CAD file is reviewed by the AME-3D production team  
  2. CAD file is set-up in the SLS  system  
  3. A laser binds the powder particles together based  on the file specifications  layer by layer until the build is complete.   
  4. The loose  powder is removed,  and the part is processed according to the chosen finish

Cost-effective

Robust

SLS Production Application and Uses  

  • Functional  and durable  prototypes for  mechanical  testing 
  • Complex geometries  and precision parts 
  • Cost-efficient production of unique and personalised products 
  • Lightweight designs with lattice structures  
  • On  demand part manufacturing  that rivals  injection moulded parts  
  • Suitable for low volume production  
  • Increased  recyclability  compared to alternative 3D printing technique

Benefits

 SLS  is  the most  versatile 3D printing technique that bridges the gap  of low volume production  and  precision  part manufacturing. Its main benefits include:  

  •  End-use functionality  and materials 
  • Durable products suitable for mechanical testing  
  • Chemical resistance  
  • Repeatability 
  • Able to tackle complex designs  due to no
    support structures being required 
  • Cost-effectiveness 
  • Can be painted or pigmented any colour
