Small gaps printing mostly filled

Hi all, I am new to 3D printing and trying to figure out how to use this printer properly. I am trying to print this: Phone/Tablet Stand - Flat fold - Print in place! by jonnig - Thingiverse
It clearly has a lot of successful prints on FDM printers, but when I tried to print one the gaps which you are supposed to break apart to allow the hinged pieces to work, are almost completely filled in and will not simply break away.

I was able to cut away a little bit with an x-acto knife, and got part of it to separate, but the rest will require a lot more force and I assume the hinge will not work. I printed in Standard Grey resin, I initially tried it in 100 micron resolution, then tried 25 when that failed. Same issue either way and it doesn’t seem to have made much difference.

I printed it relatively flat to the platform, probably about a 10 degree angle to it, using supports and a raft. I have no idea if that is appropriate for this model?

I appreciate any advice!

Try printing this part almost vertical(so when flat on the bed, rotate by 60 degree up) and 45 around it’s Z axis. But this does not solve your issue.

You can’t print something with hinges very easily on an SLA printer unfortunately. Gaps need to be something around 1mm to work.

this is called printing a “live” hinge. SLA printers are not suitable for printing most objects like this they are purposely designed to take advantage of the characteristics of a filament printer.

To print something like this on the Form 2- you are going to want to print the parts that are articulated as SEPARATE objects… this means importing the model into a modeling app and modifying it so that its hinges have the clearance needed for the resolution of the form 2 and will snap together after printing- or allow you to insert separate wire rods thru the hinges.

This is not a “live hinge.” It is intended to be some pin joints that are printed in situ saving a very difficult (or impossible) assembly.

The issue here is that the gap in between parts is pretty small for the Form 2. I have found that you need a gap of around 0.025" or your parts will fuse together. You may need a little more (possibly 0.03" or 0.04") - depending on the orientation of your part and your luck.

Unless Thingiverse has the solid model in a format that you can easily edit, this maybe isn’t an ideal project. What they are trying to do is easily done on a Form 2 - but only with the right clearance between the parts.
