Make an empty object for 3d printer

Hi guys!

I’ve got a small problem. I’d like to printing my object in 3d printer. The model is full inside and I need to prepare the body model to a suitable thickness (4-5 mm).

Does anyone know any tricks to do this? Can I do that in Zbrush or other program/soft which is special for this task?

I’ll be grateful for the help!

Extract. Look in subtools panel.

Yes, I tried but it distorted the outer layer. Either I’m doing something wrong.

I use Zbrush for 3D printing and i do with creating shell. But may be you can find this other free app very usefull for that purpose.
Hereyou can read and watch some videos about it and download

Couple of questions:

  1. What 3D printer are you using?
  2. How accurate do you need the shell out to be?

I use Makerbot’s Makerware for my prints and the slicing software will automatically create hollow fills to a given specification.

You could try duplicating your model. Go to deformation and select a negative value from the Inflate slider. Where the mesh gets messy use the selection lasso to hide broken areas. Once hidden go to Geometry > Modify Topology > Delete Hidden > Close Holes. Add a connection to the outside surface and then it is a matter of using the DynaMesh functions to boolean subtract the parts together. All a lot of work, you may be able to achieve what is require from a freely available slicing engine (depending on 3D printer).
