think3D top10: Free CAD softwares for 3D Printing

3D Printing process starts with 3d designs, which can be either available from different online repositaries or can be created using 3d CAD softwares. For creation of basic shapes and designs, you do not need to be an expert in CAd design. In fact, a lot of free softwares and corresponding online tutorials can get you started with CAD design till certain level. You need not be an expert for creating basic designs for initial prototyping.

We are trying to a list of good softwares which are intuitive, free and can let you create decent output for 3D printing. Of course, for any complex designs or specific requirements, our in-house team can always help you.


TinkerCad is a browser-based 3D design and modeling software that you can access through your browser. The best thing about Tinkercad is that it does not require any kind of previous experience, but you can just go and start designing by selecting pre-designed objects. They can then be modified by changing the positions, dimensions and can be finally combined together in to a single shape to be downloaded as a 3D Printable STL file.

OPENSCAD is a free 3D CAD software for creating solid CAD objects for programming enthusiasts. It is not an interactive modeler, but rather a 3D compiler based on a textual description language.It relies more on what you defined in the parameters through the script files, than on the interacrtive modeling, and hence is more appealing for engineers and die hard modeling enthusiasts, who relish in seeing in their code come to life in the 3D printer.
