There are different types, and each one works differently: the solid modeling software are most suitable for mechanical parts, including free ones like Google SketchUp, Autodesk 123D, Tinkercad, Blender the sculptural modeling software are useful to achieve figures, faces, human parts, natural objects because they allow to sculpt the basic three-dimensional shapes, for example with the free software Sculptrisvirtual sculptures can be realized through the concept of clay modeling clay finally, we have the parametric modeling software, which allow to combine different forms between them, defining in a very precise way each minimum variation due to the setting of the parameters (among open source we mention OpenSCADand Grasshopper). You can find many, and open source 3d printers software are quite common.ĬAD are software used to design and create digital 3d objects. Let’s start from the beginning: 3d printing is makers kingdom, and it’s often used in do-it-yourself, but obviously, before actually creating the object shape, you have to start with a pc design software in order to create digital 3d objects. For 3d models you need three kind of software: 3d modeling/CAD software, slicing and Client software.
