Fence/Support railing, how to get it off properly

Postby TObiasFP » 2014-Mar-Wed-03-Mar

Hi all.
I have searched a bit on the forum for an answer to this, but it may be my lack of English knowledge which stops my progress.
Anyways, I have built some stuff, which needs support railing/fence to build properly, and i dont know how to get it off to make the print look good.

What would all of you suggest?

How do you "snap" it off, and afterwards, if some remains, would you sandpaper it down, or what is your approach?

Sorry if this is a repost, i could not find anything on it.

All the best,
Toby

Hi, before using support material you need to play around with the settings. The support should just be enough to allow the object to bridge properly, but leave enough air so the support material just crumbles off. It is a bit hit and miss and changes for each object. If you use the defaults, you will get solid support which is impossible to get off. That setting works fine if you are using soluble support material on a dual extruder printer.

The couple of prints I've done with support I had the settings set to a 45 degree cutoff, rectilinear support material at 2mm (although I'm sure that the settings are print subject dependent). When complete the support material easily pulled off the piece with a pair of needle nosed pliers and needed minimal "touchup" with a #11 xacto blade to remove any flashing left behind.

I was actually rather impressed at how easily the material was removed.
