Good afternoon everyone!

I have a quick question.

I am looking for some clarification on the modeling techniques used to print.

Does is matter how your different meshes interact?

For example, I have two cubes modeled and I want the two cubes printed together.

Does the mesh have to be a single mesh, or can it simply be two cubes intersecting in the 3D space? Will this print? (the meshes are both watertight and non-manifold)

Thanks!

Your model will print the way it is. Shapeways just takes the surface of what you see to print. Get a copy of http://www.netfabb.com/basic.php open your stl file in this WYSIWYG. Depending on the size of your model, you may want to think about making it hollow to keep the price down. This link will be useful http://www.shapeways.com/tutorials/

Joshua it will work. Select 1 cube, then the other then export. SW will apply a boolean union modifier to any two separate objects whose volumes intersect in a uploaded file. Results create a single mesh, a well defined volume and a unified surface. Make sure all face normals are facing in the correct direction, besides the meshes being manifold


Have any questions regarding Blender, and need fast answers, you are always welcome at the IRC Server Freenode, channel #blender. As a bonus, several there have experience in modelling for 3D prints.
