Obvious 3D printer technology based on 03. Local Quality: Difference between revisions

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.

1. adjust print settings for specified areas of object for tighter tolerances
2. increase variance on some print parameters (temperature) to allow some areas to be printed faster than others.
3. use lower quality materials in don't care areas of parts
4. change control parameter to pressure instead of temperature for different extrusion materials in different parts of object
5. include only high quality parts where precision is important, else use crap quality
6. map print bed to account for non uniformity in print surface.
7. add guards around some mechanical areas of printer to prevent entanglement, leave others exposed to allow open movement.
8. change frame material from high quality wood to low quality trash as it isn't mechanically important
9. multiple print heads that are automatically changeable for quality where its needed
10. use multiple print heads of varying quality in parallel
11. alert user when printing difficult sections so it can be closely monitored
12. use feedback to alter print speed based on head resistance
13. control environment quality around print head but leave print enclosure at ambient
14. allow for localization of thermal control for print bed to conserve energy and allow for better release
15. include high precision components for bed leveling, cut costs in other locations
16. change infill for unimportant areas of print to cut material usage
17. cool filament before it enters extruder
18. bigger, sharper teeth on drive gear to allow more filament force
19. self cleaning drive gear
20. control environment filament is stored in when it is in use
21. flash cool filament after it is extruded
22. add sacrificial edge to aid in print removal
23. use subtractive manufacturing where tight tolerances needed.
24. auto switch filaments to use waste or recycled plastic for infill and new plastic for outer shells
25. reversable print bed for multiple materials
