Transcript of "RepRap Presentation VSE Prague 24.3."

  1. 1. Open Source self-replicating 3D printer Josef Průša josefprusa.cz @prusajrThursday, March 24, 2011
  2. 2. What is 3D printer? • Additive processes vs. substrative processes • 3D printing adds material instead of milling it awayThursday, March 24, 2011
  3. 3. How does 3D printer work? Y X 2D + 2D + 2D + 2D + 2D = ?????Thursday, March 24, 2011
  4. 4. How does 3D printer work? Z X YThursday, March 24, 2011
  5. 5. Simplified principle Cartesian robot + Extruder Z + X Y = 3D printerThursday, March 24, 2011

  10. 10. “History” • 2005 - Founded by Dr Adrian Bowyer at the University of Bath • 2006 - First part printed • 2008 - RepRap Darwin • 2009 - RepRap Mendel • 2010 - Huxley, Prusa MendelThursday, March 24, 2011
  11. 11. 2006 first printed part • Chicken and egg problem photo by Vik OliverThursday, March 24, 2011
  12. 12. 2008 Darwin • First printer released • Big, bulky, hard to assemble • But it worked!! photo by Adrian BowyerThursday, March 24, 2011
  13. 13. 2009 Mendel • Smaller • Faster • Faster to replicateThursday, March 24, 2011
  14. 14. 2010 Huxley • Even smaller • Still PITA to assemble • Smaller build area photo by Erik De BruijnThursday, March 24, 2011
  15. 15. 2010 Prusa • Almost no bearings, using PRINTED alternatives • Build time reduced to few days for newbies • Half replication timeThursday, March 24, 2011
  16. 16. 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
  17. 17. 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

  25. 25. 3D printer in every home • First in hackerspaces, which will work as 3D copy centers. Basically happens now. • Nobody can guesstimate when 3D printer will be in every homeThursday, March 24, 2011
  26. 26. http://brmlab.czThursday, March 24, 2011
  27. 27. Why Open Source • You can’t sell more then one self replicating machine. Its bad business model. • Much faster development • No worries with patents, more time for developments • Free open source educationThursday, March 24, 2011
  28. 28. RepRap project structure • 22 “admins” • mostly administration • everyone contributes, doesnt matter if hes admin or notThursday, March 24, 2011

  30. 30. Build party MaastrichtThursday, March 24, 2011
  31. 31. Build parties • People forget how awesome is it to create something with their own hands!!!Thursday, March 24, 2011
