Notice: Broad and/or obvious patent claims for 3-D printing technology may hamper the open-source 3-D printing community's ability to innovate. Previous work on an algorithm protected 3-D printing materials. This page is part of a Open Source 3-D Printing class project to investigate 3-D printing concepts using TRIZ and is presented here as a defensive publication of prior art to help identify obvious 'inventions' for 3-D printing.

Examiners: The ideas on this page dated April 2017 were developed by university students with less than a semester of formal 3-D printing experience (or by an instructor in class) and thus should be considered unpatentable because of obviousness to any person skilled in the art of additive manufacturing.
Appropedians: This page is open edit. Please fee free to add ideas and sign them below with ~~~~ or to use any of the ideas to built better open-source 3-D printers.


  1. improve resolution (atomic)
  2. improve print speed (instantaneous)
  3. enhance material availability (all)
  4. reduce parts of the printer (1?)
  5. reduce costs of printer (free)
  6. reduce costs of materials (free)
  7. make it easier to use (McDonald's screen)
  8. make it easier to assemble (self)
  9. make it easier to maintain (none, unbreakable, self healing)
  10. make fully assembled products (anything - computer, car, smartphone, dinner)
  11. use functional printing materials (e.g. electronics)
  12. reduce waste (zero)
  13. use less energy (zero or ambient)
  14. quieter printing (soundless)
  15. ubiquitous printing (everywhere)
  16. print smaller (nanoscale)
  17. print bigger (apartment complex, Great Wall of China, planet?)
  18. enable auto calibration
  19. enable auto leveling
  20. enable auto monitoring
  21. enable quality control
  22. enable real-time feedback
  23. make it safer (infant approved)
  24. make is smell good (designer imposters?)
  25. make it from current waste products (CO2, flyash, spent fuel rods?)
