Support generation - how to move object in z direction
Dear all,
I'd like to print a structure similar to the one attached .You see an extruded rectangle which has a border which is slightly higher than the rectangle itself. The border exists on both sides of the rectangle and is less than 1 mm in height. If I print this structure, support is not created between the rectangle surface and the print bed, as there would be only 2 support layers. However, without support, the area on the print bed basically is flat. Is there a possibility to move my object in z direction so the first - let's say - 3-4 layers are "support only"-layers so I have a proper border on this side of the object?
Thank you and best,
Christian

Please attach your project file (save project as to save a .3mf file) , zip it up or the forum wont accept the file type. a Proect 3mf files stores not only the model but all the settings you are using to slice it. It makes debugging issues vastly easier.
Slicer doesnt allow you to move a part in the z axis off the bed normally. There are ways to achieve that though, which is why if you post your 3mf we can modify it and post it back as an example showing how that can be done.
Also you may not be getting support generated as by default it wont support bridges and that area is likely to be treated as a bridge. Once again with the project file we could tell what settings you are using.
One thing you can do is turn on raft, which will print a layer(s) below the model so that the model is off the bed. Surfaces printed on top of support though generally dont look good no matter what method you use.
For that part personally I would print it standing up on either the short or long side edges, or tilt it back at 45 degrees and then add some support enforcers strategically to give some initial support to the bottom few centimetres as the rest would pretty much print ok. Once again with the project file an example could be posted back.
