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. A printer that will constantly monitor and send live updates.

-Camera for live updates

-Messages sent to user- 'print done', 'print failed', etc.

-Before print, check conditions & inform user of probability of success

  1. A sensor that checks for filament
    • A little laser tripwire would go above the extruder
    • This tripwire would constantly be checking for filament, as long as the laser is tripped, it will know that the printer is still getting filament
    • If the extruder is no longer getting filament, the laser would connect, and this would make the Arduino print a message to the screen saying, "Low filament, pausing print" and make a beeping sound to alert the user.
    • To continue the print, insert more filament and hit the "Resume Print" button

camera or 3D sensor apparatus connected to a computer which will monitor the progress of the print. If a tolerance is exceeded during the print the print will be shut down and the user will be notified that it failed
