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.


Thermal Expansion- currently, materials expanding/contracting while & after printing can be a serious problem for precision prints. If thermal expansions weren't so much of an issue, precision prints would be better and easier.

Examples of solutions include

  1. Improving materials so they do not expand/contract as much while printing
  2. Improving software so it better accounts for expansion/contraction while designing prints, so WYSIWYG can apply to 3D printers
  3. Improving hardware so it will automatically account for expansion. Probably not as good as improving software.
