Hello everyone. I have a question about 90deg overhangs. What are some good methods to support 90deg overhangs?

I’m currently using Slic3r 1.2.9. I did a first print with 90deg overhangs and I don’t like how its coming out. It’s doable but it’s not coming out how I want it, and I think this is because Slic3r will not allow me to get close enough to the support material.

You have two options in Slic3r, 0.2 (detachable) or 0(soluble). I’m not working with soluble material so I’m forced to use 0.2 as the spacing used between the model and the support material.

I currently have my fan set to 100% output so I’m figuring the print is getting enough cooling.

Any suggestions?

add supports using meshmixer

Thanks I’ll try it. However after looking at the YouTube video you posted it doesn’t seem like the right tool to generate support for overhangs similar to a dining room table, but I’ll see and provide updates. Thanks again.

there are many videos on it. one of them is autodesk themselves called meshmixer 101 best tool for adding supports

You can not only.choose between 0.2 and 0. Just type in 0.1 or what you want. (if your using that layerheight at least)

There are only two options in the drop down menu. If you try to change it it defaults to 0.2(detachable)

get a free trail of simplify3d and have a test of there support structure. By far the best i have used personally.

Yes, there are only two options in the dropdown, but it is also an edit box and you can type values that are not in the dropdown.

The other option is to use mesh mixer to find the optional orientation. This will minimize the required support.

Try it before you judge, mesh mixer places the object in crazy orientations but they typically print really well.
