What kind of software can I use to create 3D CAD models?
There are many professional options you can choose such as Solidworks, Inventor, Rhinoceros. There are also some free software like SketchUp or Blender. Always export the file in .stl before going to printing.
We also organize training courses on different 3D modelling software at our headquarters in Montebelluna (TV).
