Obvious 3D printer technology based on 37. Thermal expansion

This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printingPlease leave comments using the talk page. The course runs in the Fall semester. It is not open edit.Read more...

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.

#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. Have an extruder head with different thermal coefficients, so the heat can be radically changed throughout the print for different elements of the part Sklunsfo (talk) 07:05, 3 December 2015 (PST)
2. Use belts which can contract with thermal expansion to create greater tension Sklunsfo (talk) 07:05, 3 December 2015 (PST)
3. print bed made of strips of two materials with different coef of thermal expansion so the bed moves under the part to pop it off Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
4. inner and outer print nozzles with different dT materials to provide thermal activation of prints Joshua Pearce (talk) 07:21, 4 December 2018 (PST)

7. use thermal energy from printer to push steppers to reduce energy use Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
8. use thermally expanding earplugs that get bigger in ear to cut out printer sound Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
9. use thermal contraction at end of print to run generator to push energy back to battery to feed printer Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
10. use thermal energy from hot end placed over bed to help bed leveling Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
11. use thermal system to determine if hot end failure occurred Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
12. 4D printing using exposure of printed object to dT Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
13. 4D of components exposure of printed object to dT in specific places Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
14. use thermal expansion to open up pores to allow dip 3D printed part in material 3 to allow for composite formation Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
15. use thermal expansion to put handles on tools Joshua Pearce (talk) 07:21, 4 December 2018 (PST)
16. thermal expansion to get better fit to gripping surface on wheels Joshua Pearce (talk) 07:22, 4 December 2018 (PST)
17. 3 material printing - 1 to expand, 1 to stay the same and the third to melt fill holes for composites Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
18. 3d printing of structures that can be used as switches using thermal expansion Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
19. 3d printing of structures that can be used as motors using thermal expansion Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
20. 3d printing of structures that can be used as pumps using thermal expansion Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
21. 3d printing of structures that can be used as controls for mechanical monitoring systems using thermal expansion Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
22. use thermal expansion to push filament or material extrusion Joshua Pearce (talk) 07:24, 4 December 2018 (PST)
23. use thermal expansion to warn when electronics are getting to hot Joshua Pearce (talk) 07:25, 4 December 2018 (PST)
24. use thermal expansion as cut off switch to heating power on hotend Joshua Pearce (talk) 07:25, 4 December 2018 (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)
