    •  
    • Omax Waterjet http://www.youtube.com/watch?v=wJK-PZt6lEQ
    • -No heat damage -Width of cut (1.016 to 1.27 mm)-(0.508 mm) -Green technology/water-losed loop system/abrasive-recycled -Materiales: ubber, foam, plastics, composites, stone, tile, metals, food, paper - (45 cm) thick
    • After generating the cut path from a PNG file within the OMAX software I was also able to view the cut away in red and tool path with lead-ins in green. EXAMPLES: IN THE WORLD
    •  
    • XACT Wire EDM http://www.youtube.com/watch?v=pBueWfzb7P0
    • -High zinc content wires -Stable tensile strenght - Wire diameter >= 20 micrometres -Electric discharge machining ( EDM ) -Material removed by current discharges between 2 electrodes, separated by a dielectric liquid, and subject to electric voltage -Materials: Aluminium, Stainless Steel, Copper, Steel, itanium, Bronze, Alloys -Thick as 300mm -Power consumption is very high -For machining electrically conductive materials
    • CAMWorks WireEDM http://www.youtube.com/watch?v=8wkfT9vifPQ
    •  
    • FoamLinx Hot Wire http://www.foamlinx.com/fc2913.html
    • -Thin metal wire of nichrome or stainless steel heated via electrical resistance to 200ºC aprox. -Heat vaporises metal -Expanded Polystyrene (EPS, XPS), Expanded Polypropylene (EPP), Expanded Polyethylene (EPE), and Semi-rigid polyethylene foam (XPE) -When cutting foam, beware of the hazardous fumes

    • MultiCam Knife Cutter -Materials: Felt, Foam, Rubber, Cork, Corrugated Cardboard, Fabric, Vinyl Veneers, Leather, etc -Different kind of knives http://www.youtube.com/watch?v=cgGqjrraGVI
    •  
    •  
    • Epilog Laser Cutter
      • The beam is reflected internally (mirror) ->to lens (working zone= 0.1mm)
      • -Directing the output of a high-power laser, by computer, at the material to be cut
      • -Narrowest part - less than 0.3175 mm
      • -Precision may be better
      • -High energy required

    • Shopbot CNC Milling Machine
    • -Plywood, MDF, Aluminium, Polycarbonate -Different bits for different purposes http://www.youtube.com/watch?v=g_NB5xedD28
    • Make something 'BIG' from something very 'SMALL' Cropped and Zoomed In Gaussian Blur and Highlight Sampling (blur added to reduce noise in original image) Grasshopper Approximation of Milling Pattern (automatically generates Shop Bot g-code in real-time) EXAMPLES: FAB LAB IN THE WORLD
    • CAD/CAM Preview of Tool Path from Shop Bot Controller (simulation of final cut) The Final Installed Piece (72"x30"x1/2") The image becomes more pronounced on the oblique
