Open-source your face and 3D print your own pirate invisaligns – Boing Boing

Amos Dudley, a broke undergrad, casted a mold of his teeth via “cheap alginate powder, Permastone, and a 3d printed impression tray,” and so 3D printed and vacuformed a series of alingment trays for a fraction of what it may have cost to get name-brand invisaligns.

Obviously, this just works if you have eager access to “knowledge of orthodontic movement, a 3D scanner, a mold of the teeth, CAD software, a hi-res 3D printing device, retainer material, and a vacuum forming machine.”
But if you do, it does not appear all that challenging to roll your own alignment trays.
Interestingly adequate, a fight over exactly this kind of thing may destroy the Internet.
So what does one require to do this themselves? Knowledge of orthodontic movement, a 3D scanner, a mold of the teeth, CAD software, a hi-res 3D printing device, retainer material, and a vacuum forming machine. I accomplished, I had – or may gain – all of these things. I have my own 3D printing device, but the dimensional accuracy is not great adequate. NJIT has a digital fabrication lab with a Stratasys Dimension 1200es. That may do the trick. I tested the machine, and discovered it may donate me X,Y accuracy under .1mm, that was close adequate. I ponder a stereolithography printing device like a Formlabs Form2 may have been actually advantageous, since they have vast X,Y resolution and accuracy. Vertical print resolution didn’t matter much- the way of motion was in X and Y, not Z. The same lab in addition has a vacuum forming machine, and a few NextEngine laser scanners.
