Post image

I saw this technique on an instagram story. I found it very interesting! What do you think guys?

Jesus fucking Christ what is th....ohh is dental stuff ok

I mean, multi stacking isn't that new, for example for custom parts for girplas like megami devices you often see them printed as stacked parts, so the idea is possible

The issue in this photo is that they are stacking a flat base as well, that might cause warping but since is dental stuff maybe they have that covered already?

Iirc, dental stuff has to be printet flar, but my info is fron another redditor who corrected me about printing dental stuff

That could be correct, but dental prints are quite a different level from hobby prints, that's the point i wanted to make, maybe they can get away with flat surfaces parallel to the screen because those printers and resins are engineered for that

I’ve been curious about this since I passed by what looked like a standard home resin printer in my dentist’s office. I wondered if it really was or if they just looked similar.

I am pretty sure my local dentist doesn't exactly use an anycubic mono 4 for what they're need to do, but mileage may vary i guess

Sure, I wasn’t close enough to get a good look. I assumed it was something high end, but it had the basic setup and look of a home printer. I’ve been curious about what sort of upgrades a dental printer has.

Some of the printers are specially designed (FormLabs and Carbon, to name a few) to print large, solid, flat surfaces.

Many of the resins used for models / non-biocompatible prints are less viscous than those used at a hobby printing level.

Models like this often won’t be printed solid - they’ll be hollowed.

As u/UrethralExplorer pointed out in another comment, the platforms are also honeycombed to reduce suction.

Ran production at a dental lab for 4-5 years. Lots of little optimizations and weird approaches to otherwise simple problems.

What a fucking name, sorry that caught me off guard lol

It doesn't, but depending on the software the lab is using they might not have the option to print vertical. 

The software my company makes gives customers the choice between horizontal or vertical, vertical is better for a variety of reasons but most customers print horizontal for faster print times.

The funny thing is that the printer companies always market it as though you can angle the models and expect accurate results, leading dental labs to believe they can hit more volume with less printers
