I’ve been attempting to print a fairly large model (fills very close to all of the buildspace diagonally on my Form2) of a WW2 Minesweeper. It’s a highly detailed model which I had to convert from non -print type STL. This was a lot of work but eventually, I got it loaded into PreForm, fit it into the build space and generated support for it. In the end there were only two (small) unsupported minima detected which I wasn’t able to sort out.
One would expect from this a mostly good print possibly with a few rough areas, particularly as PreForm was showing it with little to no issues, however two print attempts failed fairly catastrophically - with the model just not printing on a diagonal about halfway through and the usual resin stuck to the tank bottom etc.
That’s the background.
Now - in general PreForm is brilliant. I just think in this case there is something seriously wrong with the file that it’s not picking up. So that’s an issue that might be looked at.
The feature request is related. I would LOVE to be able to pull the repaired model out of PreForm as an STL or similar file and work on it. The PreForm repair feature is amazing at sorting out otherwise weak files which would never print but, after a pre-form repair, will. I think that if this were an option I might be able to find the problem with the file, fix it and get a successful print. As it is I’m going to have to go back to the drawing board with my raw file and see if I can find some way to make it work - a process that is likely to take many hours with no guarantee of success.
So yeah - being able to export an STL or OBJ file out of PreForm after repair would be terrific for those of us working to get files ready to print on our Formlabs machines. Also, if someone could take a look at PreForm and maybe have a look why it says this file should print when it doesn’t have a hope, that would also be super useful.
