Is this object actually printable?

Hello to everyone, I am an architecture student and for a project I'd like to print the bearing structure of some spiral staircase, I have carefully prepared a file in Fusion 360 and I now ask myself will this geometry actually be prinatable? and also in some place I have a surface of 0.3 mm, is this maybe too small?  body45.stl


It is probably doable depending on the printer and settings.  It will need supports also just looking at the picture.


It would be a challenge but should be possible with the right printer.  I'd recommend looking at SLA to print it.
