  1. SLS - Selective Laser Sintering Rapid Prototyping Carnegie Mellon Andy Sadhwani

  2. Selective Laser Sintering (SLS) • Manufacturing Technique • Made with Plastic/Elastomer Powder • Sample built layer by layer • Horizontal Slide with Fixed Vertical Movement • Powder stays on table • Filetype ‘.stl’ used - structural triangle language • Finished sample cools for 12-24 hrs then pulled out of Powder

  3. SLS Machine

  4. SLS Powder

  5. SLS con’t • Powder • Nylon-11 • For High Strength and Elasticity • Nylon-11 with 50% Glass Reinforcement • Nylon-12 • Finer Surface Quality but lower elasticity • Elastomer • Simulate Rubber-Like Products • Strain and Tolerances Available on Website

  6. SLS con’t • No Limitation to Maximum Size • Sintered Parts can be Glued Together Easily Providing High Strength • Single Part can be 30cm x 30cm x 60cm • Minimum Wall Thickness • 0.85 [mm] for PA11 • 1.00 [mm] for PA11-GF50 • 0.65 [mm] for PA12 • 0.60 [mm] for Elastomer

  7. Example of SLS Part (Drill)

  8. Contact Information • Mareco bv Rijnaakkade • www.marco.nl • Quotes Available through Email • Price Dependent on: • Height, Finishing, File Type • Quote Available in One Day • 1 Week to Manufacture Part
