Obvious 3D printer technology based on 7. Nesting
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.

Nesting to Improve 3D Printing
- Print using filament directly from filament extruder.
- Gear reduction to do finer resolution parts.
- Introduces slack but can be limited with ball screws.
- Extruder hidden within the frame.
- Heated bed hidden within the frame.
- Half the printed bed captures the heat pad, and the top half conceals it.
- Reduces possible damage to the print bed; the printed surface can be printed again.
- Probably needs some sort of metal printed and ground surface for accuracy.
- Delta rods shorten and lengthen to change movement speed for accuracy.
- Telescoping rods with servos controlling them with a rod threaded through the center.
- Frame uses extendable vertical columns.
- Belts use straps that can easily extend the belt's usable length.
- Hide belt within frame to reduce exterior moving parts.
- (Obvious) Use traps on ALL bolts to improve looks (countersinking).
- Use sheathed bowden sheath with an interlock so that the sheath can be extended at will (for use with extending rods).
- Adds to expandability.
- Use a filament extruder directly in place of the extruder head - directly print with recycled stuff.
- Use a combined stepper driver and computer (Omit Melzi somehow).
- This is probably critical for continuing the development of our specific printer.
- Add lights inside the end effector during print to conceal lighting (aesthetic).
- Use extendable parts on the entire frame (like a step ladder or something).
- This is the basis for modular printers, so not anything new really.
- Have a segmented bed that can expand with inserts (like a table leaf).
- Use thicker vertical rods to omit exterior frame without introducing vibrations.
- Use frame as part of wireways. Just add a vertical slot in the frame for the wires to be pushed into.
- Decreases the risk of snagging and ripping out wires.
- Makes the machine more portable.
- Make the vertical parts of the frame interlock with the horizontal to improve ease of assembly.
- Use snap-together locks in place of bolts to make the frame hold itself together (can't be done with wood probably).
- Mount extruder on end effector (increase weight and momentum but decrease jams/clogs).
- Add filter to extruder to filter and extrude in the same motion.
- Add a slot to push a chunk of foam into that the filament pierces through. This can easily be replaced and adds very little plastic to the overall build.
- Builds exist for this but it can be incorporated into the extruder assembly to reduce size.
- Add vibration segments in the rods to reduce momentum vibration.
- Add 3D-printed U-joints to the end effector and omit purchase parts.
- Purchase U-joints are expensive but are more precise, so some precision is lost.
- Add cooling head next to hot end to simultaneously cool and extrude to decrease deflection.
- Add wi-fi capability to the board to make machine wirelessly accessible.
- Combine frame with beams to decrease segmentation.
- Print objects as close as possible on one print bedT.Billman (talk) 07:13, 4 December 2018 (PST)
