I recently did Invisalign, and when I got my set of aligner trays I noticed that they clearly had been produced on a 3D printer (you could see the layers made as the laser scanned across the piece).
On looking into it, I learned that the impressions my dentist took are sent off to be CT scanned and then put through Invisalign's software to generate models to be 3D printed for every iteration of the treatment. This just seemed pretty awesome to me that this was possible.
- evan_ 15y agosurely the impressions were 3D scanned, not CT scanned.
- nickpinkston 15y agoYea, totally. CT is still too expensive for nearly everything, and the data is unwieldy.
- nickpinkston 15y agoYes, it's true Invisalign are made on a large bank of SLA machines. It's actually such a large application, that every graph on "Parts Produced" for 3D printing has a adjustment for them.
