Does anyone know if there is a way to honeycomb (I'll use that as a verb here) the interior of a solid body? I'd like to do this to reduce weight and cost of a 3D printed part.
The print setup software with Dimension 3D printer has an option to print "Sparse" (interior is honeycomb) vs "Solid", Maybe you have that option?
Thanks for the advice Steve. I don't have a printer myself but am using a 3rd party; I'll check to see if they have that option.
Seems like a feature that Solidworks should consider adding tho. It would let you specify a 'sparse' pattern rather then having to rely on the printer software. You could also calculate accurate mass properties and run FEA analysis.
You'll want the 3d printer software to do this for you. If you try to do this yourself, and do it incorrectly, you could end up having the interior solid. If the 3d printer can't do the honeycomb you design, it will fill the gaps itself.
There is a plugin for Rhino called Grasshopper that that do this, and a lot more. Also, Netfabb has Selective Space Structures that can handle this type of work.
I think you'll find that most FDM printers have software which allows for some kind of internal fill patterning.
Some SLA/3Dprinting prototype vendors offer this as part of their service. Check around. Solid Concepts does this.
Like most of the others said, the "Slicing" program will let you determine the infill percentage the parts are printed at. Some higher end slicers (ie not the software that comes with most printers) allow you specify shape of infill and a few other settings. I use Simplify3D and it works great.
