ive used ac3d a lot but this is my first 3D printing project, how do make sure the parts will be printed as one piece, for example if i highlight wings and fuselage and click on merge does that mean the printer will print the fuselage and wings together as one piece? or is there more i have to do to make sure the wings are not seen as a separate part and fall off the fuselage?
thanks |

Preparing a model for 3D printing, that was not built to be printed, is not a simple task. With some exceptions, the entire model needs to be a continuous mesh. Further, there needs to be an inside and an outside.
I know Shapeways.com charges per cubic centimeter of material used, so non-hollow shapes cost way more than hollowed shapes. They also have a tutorial section at http://www.shapeways.com/tutorials The tool chain in AC3D for 3d printing is pretty much in its infancy. -There is a new plug-in for 7.2.17 that detects edges that do not have exactly two surfaces attached. It does not detect other problems like flipped normals and intersecting planes. -The extrude by normal tool doesn't always generate parallel surfaces so its hard to make an "inside" surface in some cases. |

You don't really need to worry about making hollows inside the model. Any half way decent software is going to have infill settings that auto-generate the correct hollow spaces and scaffoldings inside the "solid" object.
