Selective Laser Sintering (SLS)
Process Description:-
SLS is a direct production technique whereby the prototype is created directly from 3D CAD data. The model is built layer at a time, by scanning / sintering the surface of a plastic powder, with a computer controlled CO2 heat laser. A fresh film of powder is deposited on top of each layer, and subsequently sintered to the layer below.
Product Overview:-
• Very short lead-times
• Good physical properties (PA & PA/GF)
• Good long term stability
• Textured finish with heavy Z axis layering
• Can be finished to a high standard
(for full list of finishing options see Product Finishing & Painting )
• Non-hygroscopic
Applications:-
• Form, fit & functionality testing - incl. living hinges
• Non-aesthetic pre-production runs
• Design evaluation & feasibility studies
• High durability Presentation models
• Patterns for Investment Casting (Castform)
• Low Volume / Pre-Production Manufacture
