While there are many free CAD software tools on the market, not all of them have the features that are important for 3D printing.

The most important is ease of interaction with and integration into the 3D printing process. Essentially this is the ability to generate 3D models that can be transformed into instructions for 3D printing. The most common way to accomplish this is to save the model in what’s known as an STL file.

Another important aspect is the creation of machine instructions for creating 3D objects using additive manufacturing. This is achieved with CAM technology.

Model printability is also an important feature, especially when manufacturing or customizing parts. Some platforms create models that will need to be repaired after printing.

Lastly, CAD software for 3D printing should also be easy to use when modeling and creating objects.

Having seen what makes CAD software ideal for 3D printing, let’s take a look at the best options.

Level: Intermediate

FreeCAD is a free, open source parametric CAD software modeler. It’s considered to be a great entry point for designers and mechanical engineers new to the modeling world. Parametric modeling means that one can modify a 3D model by browsing the model history and adjust or change individual elements.

FreeCAD is ideal for precision design, which is good for technical and replacement parts.
