Obvious 3D printer technology based on 21. Rushing through

From Appropedia



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 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.

The following contributions were made by Srschroc (talk) 20:03, 3 December 2019 (UTC)

  1. Vary speed of infill extrusion so that it is faster at the center of the part where tolerance is less important, but slower within x mm of walls.
  2. Preheating element for prepping filament for extrusion.
  3. Make filament adhere to itself better so there is no need for support material.
  4. Develop better adhesive to remove the need for rafts or brims.
  5. Automated spatula to remove parts when completed so parts are cycled more quickly.
  6. Allow printer to print multiple layers in one section before catching up in the next section. Remove the need to jump back and forth.
  7. Print only exterior walls, then pour in filler material for inside density.
  8. Multiple extruder nozzles pressed together to make wider flows.
  9. Oven-like enclosure to decrease warp of part and increase extrusion speed.

Round two, without real-life constraints Srschroc (talk) 20:54, 3 December 2019 (UTC)

  1. Have a block of powder, then light shines from specific angles and where it intersects the powder solidifies.
  2. Filament is liquified as a blob, then a balloon inflates in the center to make spherical parts.
  3. Describe a part to your printer with your voice, and it prints the object you describe
  4. ^This but you only need to think it.
  5. Print in strands so fine that you can make fur-like insulation.
  6. Make your printer assemble or dismantle instantly for quick use.
