Nothing new really but it can be a handy technique if you need support and the one offered by your slicing software isnÃÂ´t good enough.
A cylinder is quite a good example i think, iÃÂ´ve tried many different ways (ok, standing it up doesnÃÂ´t count in this case) but it always come out rather useless.
Of course you can add this technique to lotÃÂ´s of other shapes aswell, itÃÂ´s just an example.

Open up your CAD software, draw your shape (in this case a cylinder), add support like in the pictures, BUT leave a gap between the two pieces, in this case itÃÂ´s 0,2mm but you might have to change this to play well with your printer
Print and remove the support carefully with a knife. If there is a need for excessive force thereÃÂ´s not enough gap between the parts or the shape is to complex. Of course you canÃÂ´t have to much of a gap either...
