How to Design 3D Printed Bores Without Supports

- Bores/offsets/recesses are a common feature in design and can be used to make your parts more aesthetically pleasing by allowing nuts and bolts to fit flush with the surface of your part. In this video, I show you how to do this without supports!

This will save print time and material for sure. Usually I model supports right in the cad program, slicers sort of fail there. Great video thanks.
Nice! Glad you liked it!
I respect you for giving credit.
Oh yeah! Definitely not my idea, but maybe I explained it so others can try it out!
I saw the original video and thought it was a good technique, but this video really slows it down for us rookies. Thank you.
Nice! It’s helped me remember how to do it by making this video haha
There were some really nice techniques in this. I'm always looking for tricks in Fusion to improve my modelling, and there were a lot of approaches in this that I could apply to workflows other than supportless bores (though I'll likely use those too).
Thank you! Glad someone got something useful out of it!
Thanks for the demo. I was intrigued with Angus's video but he left me wondering the details. Appreciate the time and effort 👍
Glad you found this one! Thanks!
thanks for the thorough tutorial!
- QUICK TIP (in PrusaSlicer): Arrow keys to step up/down one layer at a time :)
Thanks Swami!
I stumbled onto something similar just recently. I created a two layer net like support structure that bridges across the gap supporting the overhang. This is quite a bit simpler than my method. Chamfers in the bore work pretty well in small holes. you can also get away with 90 degree overhangs about the size of the nozzle.
once the overhang gets larger than 1.5mm or you need that sharp corner, something like this is pretty much the only solution. Digging support out of holes is miserable work.
Appreciate it!
- Good job :)
Thanks!
i just leave a 1 layer section in the middle so the circle prints ontop of a bridge then cut it out after with a deburing tool
Nice yeah that works as well but might get old if there are a lot of holes or a lot of products
anyone know if something similar is possible in cura?
This is mainly at the CAD level, but it might be possible by cutting away from layers using Cura. It would be a lot more straightforward to do it during the design steps rather than in the slicer though. Maybe eventually they can make an option to do this in the slicer, but I’m unaware of one that currently does this
just arc hallway construction, from the early ages, curve upwards
Then you have an arc, not an offset for a bolt head or nut
@@madebyjwillis um print it upside down? so that its naturally self-supporting? always have it designed such to be printable without supports, ie the narrow part sits on the bed
@@madebyjwillis what so impossible about this
@@madebyjwillis how about minimal support cut-out arcs, if you need to print a hanging bar, no need to build supports from the bed up to the bar, just minimal side-support with removable arcs
@@Jkauppa that’s not the point. There are plenty of instances where you want to print with an offset facing down towards the build plate. This was for demonstration purposes only. Feel free to use your way since it’s better anyway 👍🏼
Did you try printing it upside down?
That’s not the point of the video - I am fully aware you can easily print it in the opposite orientation. I just used a basic shape as a demonstration.
