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 MTU 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 Dec 3, 2015 and Nov 29, 2016 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.


Invert the action(s) used to solve the problem (e.g. instead of cooling an object, heat it). • To loosen stuck parts, cool the inner part instead of heating the outer part. • Bring the mountain to Mohammed, instead of bringing Mohammed to the mountain.

Make movable parts (or the external environment) fixed, and fixed parts movable. • Rotate the part instead of the tool. • Moving sidewalk with standing people. • Treadmill (for walking or running in place.)

Turn the object (or process) 'upside down'. • Turn an assembly upside down to insert fasteners (especially screws). • Empty grain from containers (ship or railroad) by inverting them.

  11. or multiple materialsMatthew Olson (talk) 07:07, 4 December 2018 (PST)
  12. Have the entire frame on wheels and can use a larger print bed that it drives around on, increasing the print volumeMatthew Olson (talk) 07:07, 4 December 2018 (PST)
  13. Have both the platform and bed moving to increase printing speed and keep jerk reduced on print headMatthew Olson (talk) 07:07, 4 December 2018 (PST)
  14. Design rotation printer, prints on a central axis using pole or stick and the part rotates around the axis while being printedMatthew Olson (talk) 07:07, 4 December 2018 (PST)
  15. Print head is built on the side of a printer instead to make vases and such quicker, again rotating printMatthew Olson (talk) 07:07, 4 December 2018 (PST)
  16. Using extending rods vs ball joints to increase print sizeMatthew Olson (talk) 07:07, 4 December 2018 (PST)

  1. Motors on Extruder rather than base
  2. Use pellets or liquid instead of filament
  3. Motors on moving parts instead of base(on the pieces that connect to rods)
  4. bed moves instead of extruder
  5. ball bearings on extruder and magnets on poles
  6. Non-fixed bed instead of fixed for better leveling
  7. Only use recycled materials instead of filament
  8. Use Quick Cooling filament that is extremely sturdy
  9. Print upside down
  10. Instead of printing, mill it
  11. Make base move instead of bed (X and Y)
  12. Use a combination of printing and milling for better precision
  13. Reuse milled filament
  14. Combine and Delta and XYZ
  15. Use a moving print surface for multiple colors (one on each side of base)
  16. Base is top and bottom is print surface encased in foam for sound isolation
  17. Power for head through connection rods.
  18. power for resistor through connection rods
  19. power for fan through connection rods
  20. recycle power from extruder for other uses in printer
  21. Use power from environment to heat extruder (sun, ect)
  22. Use tears of students as lubricant for print rods to make it quieter.
  23. Use camera to get feedback on print into system
  24. Use ir sensor to get feedback into system
  25. allow print surface to tilt for additional leveling features
