Make a hollow model solid again with Blender

Would it be possible to give the actual name of a function being used rather than just saying to press L then H etc? My use case is I use the industry compatible key map so I need to find the function myself. But even for someone using the default keymap it could be good for them to be told what’s happening rather than rote keypresses. Thanks for taking the time to make these!

Thankyou.

Hi! In my case the hollow is connected to the outside, it is not just a separated object inside with inverted faces. Also the outside is very textured making it a lot harder to select. By using L it selects everything including the "hollow". Any insights will be appreciated, thx

My use case was I downloaded a file I bought on cults3d and the creator had created it hollowed which makes it nearly impossible to print.
After making it solid, I was about to hollow it myself but with infill to support the insides.
Thanks for the video!

What does the action L do? Hitting L doesn't seem to select anything for me. When I just select the model by clicking on it, it all disappears when I hit H to hide. It's hiding the entire model and I'm not left with anything to delete. I can see shapes inside the model when I turn on X ray and when I slice it there are weird gaps inside that show up as solid on some layers that print but not others so I'm sure there's something odd going on inside this model.

How would one make a model solid, that has been hollowed for printing in several parts? Those models are usually made hollow, but with holes, that connect the inside surface with the outside surface, leaving you essentially with just one surface. This method seems to not work in that case... Any other methods for that known?

The reason this is helpful for people like me is for 3D printing!

your volume is so low I can barely hear your voice. 😞

hi good guy What is the name of the plugin or software that displays your mouse and keyboard operations on the screen? It is beautiful and concise

im have a model thats already made and im trying to delete the connection points on the inside of the model as i cant hollow it out in my slicer correctly without having a buggy mess, this did not work for me, is there something im missing or am i looking for the wrong solution?

Thanks! I made a low-poly torso that appears to be missing a bottom vertex and on closer inspection my extrudes were done on vertices rather than faces, so I got some hollows instead of faces because I didn't select all the vertices when extruding. I found this video immensely helpful!

This is helpful as i have purchase models that are oddly sculpted or assembled with hollows that cause printing issues.

Hi, I have a Terminator Endoskeleton head.

I need to kake a hole into the eye and holow the head so i can put leds into it.

When I try the bohemien method, i get an error message,

Could you help me out and make a hole into the eye of the headsculpt?

Would be awesome!

Thanks!

Ive been looking for this for a months, was using 3d builder but it always make my model mess up. Thank you!

pressing h hides both inside and out of model. What am I doing wrong?

pressing "L" does not work to highlight anything when i hover over my model it instead only highlights one vertice :/ is there anything i can do?

This video is great unfortunately it hasn't fixed my problem. I sculpted some crystal formations and made each crystal using a circle plane with 5 sides extruded and filled the top and bottom (which I thought would make it a solid object I was wrong haha) all I have is planes technically but trying to make it solid this method isn't working it has however fixed my mech I was making

Thank You!!! I have just taken up 3D printing again but now with a resin printer. One of the things I have been trying to print is a 12 scale doll using MakeHuman. The problem I had is that the exported file has cavities for eyes and mouth and when I hollow out the model in my slicer it just adds walls around them with no way to drain the resin trapped inside. I'm not very savvy when it comes to Blender and you wouldn't believe the number of different terms I have done searches for trying to find the answer to my problem or the amount of time I've spent searching - I have learnt a few things I didn't know, so the searches were not entirely fruitless :-) So again thank you.

This is helpful! thank you.

You are doing a great job. This will help lots of people 👍🏻

Thanks! The use case I have here is to fill a hollow model that's too big, so that when it's all printed and assembled there is no chance of liquid uncured resin on the inside. I found that some models with a lot of volume internally can have liquid stay inside there and eventually cause problems.

ive been looking for this info for years. thank you. now i have some 3d printing to do again

Thank you :)

Now that's an unusual technique!
