Digital Fabrication Methods

SLS (Selective Laser Sintering) Additive Method Layers of plastic powder are melted by a laser to create complex 3dimensional forms. + High grade of detail + rather rigid models + multiple materials possible - rather expensive promovideo of shapeways - a 3d printing service Fabrication Technologies CNC Milling Subtractive Method A computer controlled milling machine that works on most hard materials, including metals. + high quality modells + wide range of materials possible - not trivial to program the machine > numerical control (Wiki) Example: FDM (Fused Deposition Modeling) Additive Method  http://www.youtube.com/watch?v=WGIFujG0vzc [/youtube] LOM (Laminated Object Manufacturing) Additive Method http://www.youtube.com/watch?v=ZBgmKQL1--4 [/youtube] Alternatives: Stone spray project: http://vimeo.com/48009695 Sugar printer: http://www.3dsystems.com/blog/2013/09/sugar-based-3d-printers
