![]() ![]() If we imagine printing the object, we have to imagine it as if its volumes are solid, connected to each other. Closed means to "tight seal" ( watertight). ![]() To give a volume to the surfaces it is sufficient to extrude them, so as to obtain solids Often drawing for renderings or animations we create surfaces without any thickness: with 3D printing we will create a solid object, real, which must therefore have a thickness, even minimal. In particular, these simple precautions must be taken into account:Īll objects must have a volume. One of the causes can be the use of operations Boolean between two or more spherical objects, sometimes simply for the use of inappropriate modeling methods. Many of the most used software have been designed to create renderings, not for 3D printing: they can therefore generate objects at first sight perfect, but whose geometries contain errors. There are some basic rules that must be respected so that the model can be produced. Drawing for 3D printing is different than creating templates for renderings or animations. ![]()
