If your layer height is 0.2m, in your modeling software you can make a 2mm thick shell around your object, offset by 0.2mm, then trimmed down to only cover the lower portion of the object. It works well. The details of how you do so will depend in your modeling software. Then the support will hold up the shell, and the shell will hold up the object.somepunk22 wrote:And how do you add a raft to the top of support in S3D? Trying out a designed support now. Does the auto part alignment feature ever work? Figure something that was imported with the same coordinate system would be easy to align...3Dprintergear wrote:You don't have to make it so complicated. Both the Zortrax and UP/Afinia printers use a raft on top of support before the object and both of these printers are class leaders in this department. Zortrax having copied the UP. Works fine on all sorts of irregular shaped prints.
Leave support the way it is and simply add a raft on top. The interface layer (raft) should follow the contour of the object.
The result looks great! But it's a fair amount of work. So it'd be great if the support generator were smart enough to do this instead.
