    Hello dear colleagues,

    Printing the models is a no brainer but do any of you have experience with 3D printing the aligners? I'm talking about the Dental SG (Surgical guide) resin from Formlabs (which is from NextDent anyway) or also the OrthoClear from NextDent running in the Form 2? In which thicknesses would you print them?

    Pro vs Cons to sheets like Zendura? Maybe @Almine can answer any of those questions?

    It would be a real labor saver, but I am skeptical about the materials. I think if they worked as well as Zendura or Duran we would be seeing people post here and other places about it.

    envisiontec new printer and material looks pretty good to me?

    It is SLA Laser. Not projected light.

    FDA materials for this.

    Maestro 3D software already allows users to export STL's of aligners for direct printing, but as far as I know there are no material neither proper machinery exist to print non-toxic, flexible, rigid and transparent aligners which can be worn for 22 hours a day. But I know at least two companies actively working on such tecnhology. One of them claim to make a completely new type of aligners which will be able to move any teeth to any directions without any limitations. And if everything goes well, it will be realised within a year.

    Actually I mentioned another ones, which are not that famous and they are working not only on the material but also on special-designed machinery.

    Yes that is, but those guys have alredy got 60+ patents for that technology in the US and now making clinical trials. So let's wait and see the results.

    We have SLA, SLM, Digital light projector 3d printers, multi-jet printers, extruder printer, CNC mills.....all can make the aligner.

    Why do we need a new machine? :wacky:

    Looks like some inventors are not happy with the existing ones and it's easier for them to modify the printing technology. Or maybe they just want to create some closed system and start selling it for making more money then on selling a material only.

    Thanks for the info!
    Please share more when ready.

    What about the Dental LT Transparent resin made for aligners? It's not out yet I think?

    Why not just use a vacuum former to make them? Clear correct does that not sure about Align. Sounds quicker, faster and cheaper to me.

    I'm using a thermoformer now, but the finishing time.:arghh:

    We machine bite splints very fast and cheap.

    I would just CNC machine all of them. Zero labor.

    I know I send a ton of them to you.

    So what is the issue with finishing them? My thought would be they are not much different then finishing a bleaching tray. Please correct me if I am wrong beause I am interested in offering clear aligners and want feedback from those in the know. Also bite splints are a different animal than an aligner so I agree with the milling of them.

    Time is the issue. Using rotary tools to cut and polish the edges. Experimenting with a lot of different tools
    and techniques, but still a lot of time. Not really a profit maker for me. I just offer them to a few clients mainly to make room where needed or straighten out teeth involved in full arch cases. Would rather polish bite splints, way faster and more money.

    Have you tried the scotch brite wheels for cleaning up the edges?

    Yes and some other types from Germany. They save a lot of time, but other things are still more profitable.
    If I had a minimum wage employee that did those all day then maybe I would quit whining.

    Yeah if you did enoigh of them that would be wise to hire a low skill low wage person

    With what cnc machine you use to cut the aligner?
    A special software is needed?
