[[image:noedpatent.jpg|left|200px]] '''Notice:''' Broad and/or obvious patent claims for 3-D printing technology may hamper the [[RepRap|open-source 3-D printing]] community's ability to innovate. Previous work on an [[A novel approach to obviousness: An algorithm for identifying prior art concerning 3-D printing materials|algorithm]] protected 3-D printing materials. This page is part of a [[:category:MY4777|MTU Open Source 3-D Printing]] class [[:Category:4777_TRIZ_3D_printers |project]] to investigate 3-D printing concepts using [https://en.wikipedia.org/wiki/TRIZ TRIZ] and is presented here as a defensive publication of prior art to help identify obvious 'inventions' for 3-D printing. <br>
'''Examiners:''' All ideas on this page dated Dec 3, 2015 or earlier 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. <br>
'''Appropedians:''' This page is [[open edit]]. Please fee free to add ideas and sign them below with <nowiki>~~~~</nowiki> or to use any of the ideas to built better open-source 3-D printers.<br>
