    • What is 3D printer? • Additive processes vs. substrative processes • 3D printing adds material instead of milling it awayThursday, March 24, 2011
    • How does 3D printer work? Y X 2D + 2D + 2D + 2D + 2D = ?????Thursday, March 24, 2011
    • How does 3D printer work? Z X YThursday, March 24, 2011
    • Simplified principle Cartesian robot + Extruder Z + X Y = 3D printerThursday, March 24, 2011

    • 2009 Mendel • Smaller • Faster • Faster to replicateThursday, March 24, 2011
    • 2010 Huxley • Even smaller • Still PITA to assemble • Smaller build area photo by Erik De BruijnThursday, March 24, 2011
    • 2010 Prusa • Almost no bearings, using PRINTED alternatives • Build time reduced to few days for newbies • Half replication timeThursday, March 24, 2011
    • Number of printers • nobody really knows, most of the printers are crowd-sourced • Erik de Bruijn estimated in his thesis between 3872 and 4840 people in the community (October 2010) • But what we know for sure, community grows exponentially!!Thursday, March 24, 2011
    • Materials • mostly thermoplastics in 3mm or 1.75mm rod form • ABS (LEGO) • PLA (compostable plastic, throw away cups) • paste consistence materials • clay (ceramics) • silicone • chocolate • exotic materials • metals • chemicals for electronics printingThursday, March 24, 2011
