DESCRIPTION:One last time: Patents are good. And Patents are bad.\nAnd usin
 g the example of an ancient commercial 3D printer\, we can finally prove i
 t.\n\nAfter getting hold of a defective 15 year old 3D printer\, manufactu
 red by the inventor of filament based 3D printing\, we knew right away tha
 t we were not going to bring it back to its original working state. \n\nTh
 e reason is simple: the control board made sure that the printer would onl
 y accept filament from the manufacturer. A little chip inside the cartridg
 es in which the filament can be obtained\, made sure you would not by acci
 dent fill the cartridge with an unworthy material that might end you up in
  a bad printing experience. The only worthy filament is priced at around 1
 0 times the price of regular (so called!) premium filament on the market. 
 Which again was the only reason the manufacturer was able to sell the very
  solid machine at a laughable 40.000 € back in 2009.\n\nSo\, we decided 
 to replace all of the electronics. And the print head. And while we were a
 t it\, the print bed had to go too. And the bed leveling sensor.\nWe ended
  up with a printer that has current 3D printing features like: Klipper fir
 mware\, BL Touch\, a heated print bed\, an integrated OBC and an 8" touch 
 display.\n\nBut why was this possible at all (and how can we get back on t
 opic from this point of the story)? Well - easy! Being the inventor of the
  technology the manufacturer had their inventions patented. Which does not
  only result in the - obvious - protection of their IP but also means that
  there is plenty of detailed documentation available that allowed someone 
 some 20 years later to start an open source project that basically gave bi
 rth to the "prime father" of all modern filament based 3D printers we know
  today: the RepRap printer.\n\nMost of the components we used to upgrade t
 he ancient printer only exist because they were\, in the first place: pate
 nted (boo!)\, documented\, and then rebuilt and published (yay!) as open s
 ource hardware.\n\nTherefore patents were the tool to give the inventor a 
 chance to make money from its invention for years and thus refinancing the
  development of the technology. And those same patents made the open sourc
 e project possible\, giving all of us high-tech affordable 3D printing!\n\
 nThe talk will mainly focus on the changes we made to the printer to bring
  it to current technology in terms of hardware and software. It will also 
 discuss the role the patents play in this whole picture and draw a beautif
 ul circle from the original printer to all of the printers we know today.\
 nIf all goes well we might even bring the printer to the GPN. The distance
  won't be the problem - it's more the weight which is around 128 kg...
