angle in 3D printing without support?

[neone 40]

Hi all,

I was wandering what angle can be used in 3D printing so you don't need support at all?

Thanks a lot for the feedback.

If you are on a stock UM2, this will depend on which way the angle is facing as one side cools better then the other. Also layer height can have an effect on the outcome. Typically 45deg angles turn out pretty good.

but you can get away will quite a bit more.

You might find This quite a good read if you haven't read it already.

thanks for the info @Labern.

45 it is then, I'll try to experiment with it.

Thank you!

will do, I made a little study with 45 degrees and it looks pretty good, way better then using supports.

thanks for the help!

[Labern 774]

That's great

There is also an angle test Here that can help find the maximum angle you can print at. If you print it at different angles like your test will help show the best way to orientate your designs. But you need to do this one at a time as printing more then one adds heaps more cooling time.

You also now need to focus on getting rid of that Stringing.

Thanks @Labern for the tip,

I put the angle test up to the test and it came out pretty neat! At 70 degrees the buttom side of the piece is not that great, but it's good to know.

Wall thickness and layer heights play a role too, so you might want to experiment with that as well.

[neone 40]

I did just that @danilius

I tried a thin vertical print with some angles in it and it survived the whole ride, barely but it did

45 degrees is the general rule for good looking surfaces. If you don't care how it looks you can go almost horizontal - certainly up to 80 degrees from vertical no problem. But it will be ugly.

[neone 40]

yeah, that angle test showed a pretty nasty surface underneath on 70 degrees. 45 and even 60 was still pretty decent.

Meanwhile i tried testing vertical printing some more without supports, this time with a thicker model (2mm) ...it came out almost perfectly without a scratch!
