MOST Delta filament as guide.JPG This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the discussion tab. The course runs in the Fall semester. It is not open edit.


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.

Ideas to improve 3d printer (Counterweight):

  1. Use Mesh design for end effector to reduce weight while maintaining structural integrity
  2. Enhance material availability: Make structures out of particle board to reduce weight and use any available wood
  3. Reduce Parts: End effector has helicopter style top to suspend instead of metal bars
  4. Reduce cost-printer: Mesh design for all 3d printed parts and structures to use less material
  5. Reduce cost-material: Inject with gas to expand volume(more surface area for less plastic)
  6. Easier to assemble : attach helium balloons to top so cannot drop and easier to maneuver to fix/build
  7. Use carbon fiber frame to decrease weight.
  8. Use lighter motors to decrease weight.
  9. Add flat steel plate to base to decrease vibration somewhat.
  10. Modify end effector to only mount the hot end (alternative material to take care of heat)
  11. Add vibration reducers (similar to hunting bows) to lower rod vibration and thus the rod can be made of a lighter material.
  12. Use smaller motors to decrease weight.
  13. Use less robust board to decrease weight slightly.
  14. Use a combination stepper driver and computer to decrease overall weight (combine melzi and BBBlack)
  15. Use microphones to detect mechanical click to reduce wiring to leveling switches.
  16. Combine heated bed with the frame to reduce weight.
  17. Add heating to the whole frame to omit heated bed somehow (circuitry needs to be modified).
  18. Combine frame with vertical beams to reduce weight - or omit vertical columns entirely like on some cartesian printers.
  19. Extrude with a through-the-center stepper to decrease parts used in extrusion.
  20. Omit top doughnut entirely - vibration introduced but weight decreased.
  21. Use carbon fiber rods instead of aluminum to decrease weight.
  22. Combine extruder and hot end into a plastic pushing monster to decrease metal and mechanical parts - momentum is increased and accuracy falls.
  23. Use more snap-together parts to decrease bolts and nuts - less metal, less weight (slightly).
  24. Print with a smaller extruder motor to decrease weight.
  25. Use shorter linear bearings to slightly decrease weight.

  1. Less infill for parts that don't need it
  2. Different infill: lighter, stronger infill material
  3. Use different material for structure of printer: some sort of light, hollow, plastic tubing
  4. Change guide rods to carbon fiber
  5. Printed parts of printer with less infill
  6. Make everything out of carbon fiber
  7. Drill holes in support material
  8. Print with lighter material
  9. Plastic hardware
  10. Build a smaller printer
  11. Print a smaller part, sections if needed
  12. Use less bed adhesion (glue) or use blue painters tape
  13. Make part hollow and put hydrogen or helium into part
  14. Make inside of part a vacuum
  15. Move printer to moon
  16. Attach helium balloons to top of printer
