Upper teeth

[keokolo]

Full size upper set of human teeth with Polymax, 50% infill, 0.2mm layer, print time less than 1 hour.

Very nice job!

From the title i thought this was going to be a post about replacing the top belt idler with something like 30 tooth gears, was very surprised to see teeth, they came out nice btw xD

Makes me wonder if a full set of dentures can be 3d printed and carved to fit the human mouth, interesting!

They already use sinter based printers to make molds and models for permanent replacements. I don't think you can use an extrusion based printer to make food safe products. Crap is going to grow in the voids.

Good point that I didn't think about, I would not want all those nasties growing in my dentures.
Thanks for making me see the light!

Not to mention strength issues - there are some incredible forces generated on the teeth which I suspect would destroy any kind of filament we print with in days or less.

You are right again Captain. Even modern dentures are subjected to incredible forces by the human jaws. I bit into a hard nut not so long ago and my upper denture cracked down the middle!
I learned that the jaw muscles exert tremendous forces and that nuts should not eat nuts!

They're easier on your teeth if you take the nuts out of the shell first...

also, 55 to 200 psi depending on where you measure the force in your jaw, strongest toward the back.

You have the printer... set it to print a new every morning.

No more brushing and you can eat nuts all day long provided you have a couple of spares

[Captain Starfish]

Lol perfect solution teoman!

Makes halloween so much more fun too!

So that's what caused it! I forgot to take the shell off the nut first! I am ever grateful for telling me that!
64 and still learning! And those almond shells are tough!

It's the 5/16" Zinc ones that always get me.

You always make me laugh.

3D systems and Stratsys have a line of dental 3D printers. They are mainly for making molds from dental scans. The pipeline is still being worked out but the dental labs are going to shrink. The print was mainly a test of PolyMax, not intended for final use although it would be just fine for costume teeth. It was inspired after reading about this Chinese FFM SLA viscous material printer being able to 3D print porcelain, very fast, hundreds of times faster than FDM.

Chinese researchers make breakthrough in SLA 3D printing, soon be able to 3D print porcelain teeth in minutes

Very good information. I like to be kept up to date on what is happening on the manufacturing being done with 3d Printers.
Thanks for the update.

Yep, 3D printed dentures is already a thing. One of the guys at The Hive has done some work on resins for that kind of printing.

Jim, those pictures are outstanding! After seeing those there is a definite use for the 3d printer in the dental labs.

Ah, there's your problem.

Try metric - much better for you.

[geneb]

I've got 5/16 problems, but metric ain't one.

Did you intentionally place the teeth under the eyes, or is that a coincidence?
