I'm a marine biologist and I'm currently working on a project to 3D print a 1m^3 replica of mangrove trees for the use of ex situ (offsite/in the laboratory) observation of fish behavior.
I've recently posted a question on Reddit (https://www.reddit.com/r/3DScanning/comments/gebzg2/help_with_scanning_a_tree/) and got an advice to try out Blender to process my 3D scanned trees. I have some questions and was hoping I could get some help getting a better understanding on how this software works.
Can I fix holes on my .STL files manually on Sculpt mode (like how I can on images on Photoshop using eraser or brush)? So far I’ve been using the Edit mode, filling with Alt+F, but this mode lags so much on my computer due to the high number of verts, and manual delete is such a pain.
I’ve removed some noise using the edit mode, CTRL+L, CTRL+I and delete. However, I can’t figure out how to get rid of linked junk inside the outer layer of my object. Pic: https://drive.google.com/open?id=14cqgzwI-_OGFdGyU2AI2JvygBbWX7GQA
- When trying to solidify, I get blobs coming out of my scanned object (https://drive.google.com/open?id=1BKWV1KmYeLQR5bnJ3lA_h9FLcLLrxlsw) and I don’t know how to fix it. I do have some non manifold edges and intersect faces (checked using the 3D printing toolkit). I saw this post from a few years back but it doesn't seem to work on me. https://www.reddit.com/r/blender/comments/25jxst/easy_way_to_delete_internal_geometry/

Thanks! I'm a newbie so please go easy on me. I definitely have more questions but these should do for now.
