surely that’s not extrusion 3D printing?
@Helena It’s printed on a MakerBot Replicator…
@Helena Here’s how to do it: http://www.thingiverse.com/thing:135716
This technique can be used on a variety of different shapes.
when i print spherical bodies their bottom dont look nice,why
@yaron_atia how do you print them? With slicer generated support?
Here´s a comparison between “slicer generated support” and “block support”: https://twitter.com/d3print/status/369729304407453696/photo/1
@Paolo_Amboni download test object, print, remove support. No need to do anything else. Might have to tune printer settings though…
@Paolo_Amboni no support! In theorie this works just like printing on a raft. That means ju print a little higher so that the filament will just stick enough not to come off during printing, get it? So you might need to adjust the gap to get it just perfect. However, the distance can’t be too small (parts won’t separate) and not to big (parts will be crappy and/or come loose during printing). In this case the gap is 0,2mm.
i use up printer with the original software 90% support
no,the bottom side is not nice
