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.




  1. Thermal expansion print bed that heats up when print is complete for easier removal of part - Sklunsfo (talk) 07:05, 3 December 2015 (PST)

  1. Enclose printer so it is surrounded by high temperature air. A certain temperature could melt the layers together after they are done printing to get rid of layer lines and increase resolutionKrcipriano (talk) 07:45, 1 December 2016 (PST)
  2. Increase temperature of filament so it is almost liquid but print on a cooled bed (colder than room temperature)Krcipriano (talk) 07:45, 1 December 2016 (PST)
  3. Print with frozen objects that melt as they go through "cold" end instead of hot endKrcipriano (talk) 07:45, 1 December 2016 (PST)
