Posted · How to print features that are "in space"

I am trying to figure out how to print features that are not touching the base platform. I essentially have a model similar to a car where the only features on the base platform are the wheels. What do I have to do in order to make the rest of the model print. I am new to using the replicator G. Any help would be appreciated.

Thanks,

    You need what we call "support structures".

    Simply put, it support prints a bunch of thin lines under you model to support higher parts, later you break off the support structure and you'll end up with an "impossible" model.

    Example with support:

    After support removal:

    Not sure where it is located in RepG, but in Cura it's a simple checkbox in simple mode, and you need to select "exterior only" support in normal mode.

    Wow that is impressive. So I don't need to go back into my cad program and model these "support structures"? What I am hearing is that there should be an checkbox or option in Rep G that will take care of this for me? Is this correct?

    Thanks

    I don't know how to enable it in RepG. But the recommended software for printing is Cura.

    And yes, no need to model it. You can if you wish, and sometimes modelled support is better then automated. But that's something to try out yourself.

    Well I found the location of the support structures, however after I select full support and generate go code, the Skeinlayer screen pops up, and if I close that the model doesn't show these structures? Is the model supposed to show the support structures or not?

    Nope, the support structures are only in the GCode, and RepG doesn't show the GCode (Cura does however)

    What am I supposed to do when this Skeinlayer screen pops up. If I close it, it appears that it quits generating the G code. I have looked through the menus and I can't find what it wants me to do? Any help is appreciated.
