What Are the Free CAD Software Solutions on the Market?

Before you can 3D print a part, you have to create a model. This stage of conception is essential and can be completed using several tools, notably CAD (computer-aided design) software. They allow you to imagine any shape, whether you start from scratch or an existing model. Most of these software solutions also offer functionalities for modifying a 3D model, visualization and even simulation before printing. Each CAD software has its specificities and will meet the needs of everyone from beginners up through experts. So, faced with the multiplicity of tools available on the market today, how do you choose? We’ve put together a selection of free CAD software which will allow you to test different options without costing you a dime. However, a few offer a premium version, meaning some features will be free but if you want to go further, you will have to pay a subscription. We have therefore divided our selection into two, the 100% free software and those with premium options. Note that there are also free CAD software for certain profiles (Fusion 360 for individuals, CATIA for students) but we have deliberately left them aside.

Free CAD Software

BlocksCAD

This free CAD software was primarily designed for beginners and the education sector. Easier to use than OpenSCad, it recommended to begin with BlocksCAD. The platform functions somewhat similarly to LEGO, in that you must add take away building blocks of various shapes to obtain the final part. You are then left with the simple task of exporting the file in STL format in order to be able to 3D print it. Subsequently, if you want to design more technical and complex models, you will have to change the platform and go to OpenSCAD, a platform which is considered to be the advanced version of BlocksCAD.
