  • 2. Open Source self-replicating 3D printer Josef Průša RepRap core dev josefprusa.cz flickr.com/prusajr/ @prusajr http://slidesha.re/eurobot-ohwWednesday, June 15, 2011
  • 3. • has to provide source how to make it • must allow derivatives • ... • http://freedomdefined.org/OSHWWednesday, June 15, 2011
  • 4. Advantages • provides resources to learn stuff • faster to develop - no patent hassles • your thing is improved by others • you can repair bought OHW by yourselfWednesday, June 15, 2011
  • 5. Arduino • http://arduino.cc • GPL and LGPL license • 120 000 sold (Feb 2010) (c) Arduino TeamWednesday, June 15, 2011
  • 6. Derivatives brmduino seeeduino boarduinoWednesday, June 15, 2011
  • 7. Arduino crushed all the commercial DEV boards! And helped many people to start with electronic.Wednesday, June 15, 2011
  • 8. Wednesday, June 15, 2011
  • 9. Global Village Construction Set LifeTrac Marcin @ OpenSourceEcology WIKIWednesday, June 15, 2011
  • 10. Global Village Construction Set • goal to have 50 open source industrial machines • http://opensourceecology.org/ • founder Marcin JakubowskiWednesday, June 15, 2011
  • 11. Open Source self-replicating 3D printer http://reprap.orgWednesday, June 15, 2011
  • 12. What is 3D printer? • Additive processes vs. substrative processes • 3D printing adds material instead of milling it away • Technology is 30yrs oldWednesday, June 15, 2011
  • 13. How does 3D printer work? Y X 2D + 2D + 2D + 2D + 2D = ?????Wednesday, June 15, 2011
  • 14. How does 3D printer work? Z X YWednesday, June 15, 2011
  • 15. Simplified principle Cartesian robot + Extruder Z + X Y = 3D printerWednesday, June 15, 2011
  • 16. My experience on RepRap project Mendel Prusa Mendel I started in 2009 having no clue about HW and electronics!Wednesday, June 15, 2011
  • 17. Free stress-less education You can learn what you want, when you want, how you want. In my case: No HW and electronics experience 18 months Successful printer redesign 6 months Book published by O’reillyWednesday, June 15, 2011
  • 18. 2009 Mendel • Smaller • Faster • Faster to replicateWednesday, June 15, 2011
  • 19. 2010 Prusa • Almost no bearings, using PRINTED alternatives • Build time reduced to few days for newbies • Half replication timeWednesday, June 15, 2011
  • 20. In 3 years almost the quality of commercial printersWednesday, June 15, 2011
  • 21. New printersWednesday, June 15, 2011
  • 22. 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!!Wednesday, June 15, 2011
  • 23. Printable objects are easy to be open sourcedWednesday, June 15, 2011
  • 24. First ever working open source glasses?! GPL v2 photo by root.cz cost to print - 2€ http://bit.ly/prusa-glassesWednesday, June 15, 2011
  • 25. Upgrade in few hoursWednesday, June 15, 2011
  • 26. Printable lathe by sublime http://www.thingiverse.com/thing:9242Wednesday, June 15, 2011
  • 27. Infinite modularity, thanks to openness printed pottery by UnfoldWednesday, June 15, 2011
  • 28. Documenting OHW http://thingdoc.orgWednesday, June 15, 2011
  • 29. Printable parts We are living in the Lasercut internet of things parts That means, we can share real Hardware online! Simple PCBs How-tosWednesday, June 15, 2011
  • 30. We just don’t know how to organize it ...yet! http://thingiverse.com - mess http://instructables.com - even more mess ...Wednesday, June 15, 2011
  • 31. You can publish only completed projects. With hand tailored documentation. Software has better solutions! They can make documentation automagically! JavaDoc, PHPDoc, ...Wednesday, June 15, 2011
  • 32. ThingDOC solves that! It can generate your HW project documentation. Works on simple text comments. Printed parts, lasercut parts, ... ThingDOC is being developed on Prusa Mendel RepRap parts.Wednesday, June 15, 2011
  • 33. Generator isn’t lazy! Normally you have to change documentation with every update of the design! Thats hard if documentation is long as small book and you update the design twice a day! 1) Errors 2) Out of date documentation It causes: 3) Demotivates to update design often 4) If you use wiki, its hard to find older documentationWednesday, June 15, 2011
  • 34. Forking is hard!Wednesday, June 15, 2011
  • 35. With ThingDOC every thing in project has it’s own info about properties and relationships!Wednesday, June 15, 2011
  • 36. So when you update or switch one file, you still can get full featured documentation! Means: Easy forking! Easy updating!Wednesday, June 15, 2011
  • 37. Documentation is hyperlocal! Informations about the object are embedded in the same file!Wednesday, June 15, 2011
  • 38. What ThingDOC can do? • Bill of materials • Info about things • Assembly instruction • Structured data of your project All in many formats! HTML, TXT, PDF, WIKI ...Wednesday, June 15, 2011
  • 39. Interactive bill of materialsWednesday, June 15, 2011
  • 40. Interactive bill of materialsWednesday, June 15, 2011
  • 41. Things overviewWednesday, June 15, 2011
  • 42. Assembly instructions! BEST!Wednesday, June 15, 2011
  • 43. Works on mobile devices!Wednesday, June 15, 2011
  • 44. From what it generates this awesomness? Small comments like these!Wednesday, June 15, 2011
  • 45. Monetizing OHW • selling kits - Sparkfun, Ladyada • selling consulting • selling supportWednesday, June 15, 2011
  • 46. Thank you http://josefprusa.cz @prusajr OHW and 3D printing consultingWednesday, June 15, 2011
