Breaking up models into fitted parts for 3D printing - The Edge Split Tool

- Ive tried tinkering with the sound so please let me know if this is at a better volume.
I see people trying to do some mad things with booleans to split apart their models for 3D printing. It really doesn't have to be that hard and hopefully this video shows how to go about it in what is a vastly easier method in many instances.

Some points:
* around 2:15 When you have a region selected, don't duplicate it, just go straight to P to separate it.
* around 2:40 - you delete by vertex, but you have it selected by face. Delete by face instead.
All good points. It's just not really the point of showing how the modifier works.
I'm glad you fixed the audio issues. Awesome video btw. :)
Thanks so much 😁
Never knew what Select loop Inner-Region does. The Devil is in the details as they say... So many devilishly awesome functionalities in Blender that are hiding in plain sight! Thanks for the tip!
Glad the videos are showing some new things for people to use 😁
Great video. I wonder what would be best way to add some mounting features like dovetails.
The casual wizardry of Select inner loop region. 😅
Hehe. Well I like to throw in a range of tips 😅😉
You can literally just select the outer edges you want to separate and press V, this will separate all the selected vertices, then when you hover over the separated part and press L you will select linked vertices. After that you can press P to separate selection.
That's fair. I just prefer this way as I can model with it as one whole but put in the separating "sharp" edges to split it apart later. But both methods work.
you have got magic mate, magic
😁 Thanks so much Keith 😁😁
Smart stuff dude
Thanks man 😁
Wouldn't you want to move those faces back 0.15 to 0.20 mm in order to ensure fitment of the printed parts? Or, is the miniatures community accustomed to post-processing (i.e., sanding) anyway in preparation for painting, which would eliminate the need to design a gap into the model? Thank you for this content, btw, your channel is solid gold.
You definitely would, it just wasn't the focus of the video. I have some comments on that in the relevant part in this video:

The issue is that this can vary from printer to printer based on how dialed in the exposure settings are, so I don't like to make statements on it in passing without being able to explain properly.
Thanks so much!
@@ArtisansofVaul Perfect, that video is an excellent treatment of the topic. Missed it on my first circuit of binge-watching your channel 🙂. Thanks!
@@grandwaz0o Cheers man.
Another way to do this would be to design it for printing in the first place. I deal with lots of large models and I always design with the intention that a piece is the right size for my printer. Which then I always include the tabs and slots for putting it all together. I think of this on the lines of what a model would look like if it was a plastic model where you get it and each piece is on a sprue.
Oh of course. This is more a premise for the tutorial. For example this piece is much easier to design as part of the whole and then remove one piece as it will be used to cover joins.
Not 3D printing but cutting from sheets of material. Is there a way for splitting into parts whitch are look like extrusions. I found how to slice objects and then cutting from sheets of given thickness. But the steepness of the latter stacked parts shoud be somehow addaptive to save smouthing. I am speaking of paper, cardstock. Not a block of metall or any massive millable stock material. So halfway of additive to subtractive "production".
Sorry I'm trying to visualise way you mean by parts that look like extrusions...
@@ArtisansofVaul Ok I meant sections extending in vertical direction until there is a change in profile. As when there is a need for support if it would get 3D printed. But also when a slope gets upwards. Or like rouhging in on CNC, and then polishing.
I was madly doing things with booleans to split apart a model for 3D printing yesterday 🤣
I mean in some instances it works well. It just depends what you're doing.
@@ArtisansofVaul I'm still in the early stages of learning, and doing lots of things inefficiently! But maybe the way I did it was good for what I was doing!
@@EcoHamletsUK Understandable. There's almost always ways to make things a bit more efficient. 👍🏻
In the first example why did you make it appear much harder than needed? You duplicated the part before splitting instead of just splitting it directly (duplicating first was unnecessary), hence why you then had to go back again to remove the part from the original model. Then when deleting the selected faces you were deleting verts, which as you know removes more than you needed instead of just deleting faces which would have given you the correct result (though this entire step was unnecessary had you just split the selected part without duplicating it).
That's a good point. I hadn't really considered it. I don't really work using that method much as I find it a pain regardless as ( I'd rather put in the sharps and then use the modifier later when working on a big project so I can work ad I go but keep everything together as one object until I want to break it down). But as you say that would be a more efficient way of splitting/deleting it.
I feel like this was more complicated than it needs to be. Select the loop to isolate, split by edges.
I hadn't seen the split by edge function.... where is that?
So you're saying carefully inserting a plane, applying a loop cut to it, and then increasing its thickness, to do a Boolean division, isn't the most efficient way to achieve this? LOL
@surfimp I think it depends on the surface. If it was flat a boolean is good but specifically for non-flat edges I find this easiest/quickest.
Tried to watch this, but was seasick within the first 30 seconds. Slow down and stop jumping around,.
😅 Thats just the way I work Im afraid. If it bothers you that much you may need to find another content creator to watch. There's loads of them out there so Im sure you'll find something you're stomach/head is happier with.
Press the gear in the RUclips u.i., select playback speed, and choose your preferred (slower) pace. Easy.
