trying to print a 3d grid - space truss - lots of bridging etc

[naft 0]

Hi all,

 

am trying to print a 3d grid - its actually a 3d space truss , with slim elements connected at node, struggling to mesh it (rhino7) and slice it (cura) to anything that will actually  print!

 

i modelled it using multipipe command , to create the elements from the curves ,and then meshed it in one go (rhino7)

 

any advice will be appreciated!

 

thanks

That's not really printable with FDM.  It would require a lot of support and then you would likely destroy the model trying to remove the support.  Those cross members at 45° would be particularly difficult if not impossible.

I think you would need to break it up into pieces that could be printed flat and then assemble them.  I would think a jig would be required for the assembly.  There's lots of pieces there.

 

Does it need to be "exact scale" and exactly identical to the end design?  If a "stylized version" would be acceptable then that would be the way to go.
