Doctor, hypothetically say you did not use the hollow function. Then you add a base and essentially have a model made like an egg shell. What would happen if you tried to print the STL file? Would the printer print it as a solid? Or would you get an error because you essentially have a shell with no thickness?
Would not print as expected, if at all. Most printers software have the ability to make repairs to models. Any hole in a model that leaves it not watertight is considered an error. It's an open mesh. So, the printing software will try to close the whole. With a very large hole like you describe, it will take a while for it to try and repair a. And that is a very complex repair that if it's even capable of accomplishing, will likely be very irregular. I would not risk it. There are too many free software options out there to close your model.
@@bgrutterdds sorry I should have clarified. Let's say you have the eggshell and add a base by extrduing as you show. So there are no holes. Can you now just print it and expect a solid, or do you need to go to Edit --> make solid. Thanks for your reply and all your useful videos.
@@bgrutterdds thanks doc. If I DO want to print hollow, and use Blueskybio, should I base and hollow in meshmixer first, and then bring that file into blue sky?
I think I have it right but when I put them on the print bed in rayware I still get a message that its not printable and it wants me to add supports. Do you still get that message before you print this way?
I just remembered that this comment was from the meshmixer video. I'm reading it on my phone, so it shows up as just a comment. Anyway, if you are making these in meshmixer, I can't promise they will print. I just know that files we export from blue sky plan have a tendency to cause that same error warning in rayware and it always prints just fine.
Baron I have followed these instructions on two separate models and when I do the plane cut after hollowing I get an open space around the rim instead of a 3mm closed space. Did the smoothing too. Also when I don't hollow it and get a model ready to print, I export and open in Sprint Ray and the model is missing the base and platform and looks like I have done no work to it.
+Scott Bruggeman prior to extruding, press the B button to smooth the boundary. This will alert you to any flaws in the edge and make everything quite smooth. Moving forward from there, you should be good to go.
+Scott Bruggeman I see that you did follow the video with the smooth boundary direction. If you did that and are still having that same issue, it is one of the rare occasions where it does not notify you of the issue. The big idea is that you need to make sure the entire perimeter of your model is smooth. If you have a model with a rough border, it will have issues when playing cutting it. As for your other issue, I'd be willing to bet that when you export it, you had the original model highlighted still. You need to hit escape or clear selection so that nothing is selected prior to the export. You are basically just exporting that top surface as it has a separate surface color or as the software calls it service group. Does that make sense?
Baron, do you always recommend hollowing the models prior to printing to save resin and print faster? Or is that primarily for aligners models, since you’re probably printing a bunch of them?
Honestly, I don't really do it anymore. That's why my most current videos don't teach it. I will again, soon. Perhaps when I don't have to do it in MM 😉
Ok, that's cool. Less work. :-D That's the kind of thing that does confuse me, because sometimes I forget to look at the dates the videos were taken, and I don't know if something knewer has been posted. I can't wait for your course, but that's not until May. :-(
Baron, I'm having issues creating a hollow model. Everytime I try I end up with two shells. One, the original external shell and another internal to that that appears to be 2 mm (thickness) smaller than the original. What am I doing wrong?
At 2 minutes and 40 seconds in, I discussed using the smooth boundary tool to prevent that are. That said, if you have wrinkles or folds in the model, that still will not be enough. At the end of the video, I have other videos that pop up that are suggested viewing. The two on the left side of the video are ones that you should watch. They will help you avoid that's in the future. Also, as a side note, I now use blue sky plan for all of my model basing, Halloween, and labeling. I still love meshmixer and use it a lot for more advanced things, but these simple tasks and now we done more efficiently and for free in blue sky plan.
+rigo cano yeah, you could. But, it wouldn't correlate the c t data, so I don't know there would be much purpose. It would be like the old days of making a surgical guide based purely on a stone model in your lab.
+Ernest Mccallum good deal. Reality is, this is ever evolving. I've refined my approach MANY times. You might consider subscribing so you'll be notified of future videos/updates 😉
Baron, wonderful video. Just received my printer last week and using your videos, which are a tremendous help. Thank you!!
Hi Baron, very useful video ! only a question, why the posterior cut plan needs to be not parallel to the incisors ?
thank you very much for this updated video man! u rock!
can i ask why you add a 5-10 degree tilt when printing vertically please? thank you in advance
I don't anymore unless I have missing Posterior teeth or severely retroclined incisors. And then it's 10-20°.
@@bgrutterdds thank you!

@@thomaslim4608 ahhhhhh. Yeah. You can definitely print like that. I almost never use the "Make Solid" tool
@@bgrutterdds thanks doc. If I DO want to print hollow, and use Blueskybio, should I base and hollow in meshmixer first, and then bring that file into blue sky?
@@thomaslim4608 no. Bring the original into BSP. Then follow my videos to trim and such for BSP Ortho
Baron, in my case I’ve noticed that RayWare wants to put supports in place. How do you avoid that?
I just ignore it. Lol
I think I have it right but when I put them on the print bed in rayware I still get a message that its not printable and it wants me to add supports. Do you still get that message before you print this way?
Yep, just go ahead and print.
Baron Grutter DDS thanks!
