I wish they would have gone into more technical detail about the scanning and printing processes, materials used etc. I’m imagining plastic teeth with the layers separating
Resin 3D printing. It's how they make invisaligns, the shape is one piece of plastic.
Dental 3D printing is a different beast from consumer printers. The dental printers are already certified to actually create regulator approved devices that can go in a patient's mouth.
It might be also potentially dangerous for bacteria build up because of space in between layers. 3D printed stuff is certainly not safe for food.
Neither are ceramic dishes if you don't wash them with soap.
The printers in the video do not look like extrusion printers, but on the other hand, the resin used in other type is carcinogenic as hell as far as I remember.
Pick your poison, eh
I imagine it’d make more sense to print a mould and cast the teeth.
they probably also need to account for patients differences in individuals mouth, teeth, jaws.
he starts by 3D scanning the mouth of the patient, or an imprint.
