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.

  1. Change nozzle geometry for tighter corners/ better edges
  2. make drive gear geometry asymmetric to allow faster speeds with the same motor. Align geometry with part to be printed.
  3. additional infill on edges, leave middle hollow
  4. add flats to shaft for drive gear
  5. mix filaments in print head for color combination
  6. mix filaments in print head for combination of material properties
  7. make printer asymmetric to allow better access to print bed
  8. Change firmware to allow tolerances for asymmetric construction, then vastly increase assembly tolerances
  9. Texture print bed for better adhesion
  10. change control rods to linear actuators to allow for additional motion control
  11. add cutout to nozzle to allow other materials to be injected into print stream
  12. shiftable transmission on drive belts
  13. make drive gear geometry asymmetric to allow the extruder motor's force to be better used. Align geometry with part to be printed.
  14. adjust symmetry of drive pulses to motor
  15. specifically shape print bed for object being printed (mass production?)
  16. bring nozzle to a point on one side, orient that side inward to allow better detail, shave off the additional plastic on the outside
  17. flip nozzle in previous point
  18. mount bed on cams, drive them until bed is a set distance from nozzle
  19. mount bed on cams, drive them until bed is level
  20. novel print head shape to increase range of movement
  21. overfill inside of part for increased strength (preloading part)
  22. different length control rods for printing on an angle
  23. flip print bed sideways and add rotational axis
  24. swap nozzle sizes during print to increase strength
  25. change firmware to not care about nozzle geometry, make nozzle from random trash

  1. swappable axis drives to easily change print area
  2. oval filament to get wider layer lines at the same layer height
  3. alter fan configurations to change cooling effects
  4. adjust axis positioning to allow easier print bed access on delta printers
  5. puzzle-like snap fits for some connections rather than nuts/bolts
  6. add slightly curled tab to slicer options for easier print removal from bed
  7. create spacers and code to allow for an angled bed
  8. add automated arm to be able to place an item inside the print mid-print
  9. Allow printer to become inverted mid print to enhance build volume.
  10. Asymmetric drive gears for more precise when you need it
  11. Asymmetric hotend to lay down material more precisely
  12. Mix filaments for better material properties
  13. Mix filament colors to make new colors
  14. Multiple hotends that print materials that react with each other to form a stronger bond
  15. Asymmetric bed that adjusts until it is level
  16. Liquid bed so that it is always level
  17. Cam driven motors
  18. Asymmetric print bed to increase build volume
  19. Tilted print bed to print overhangs vertical
