Solvespace runs on Mac, Windows, and Linux, and the source code is freely available. Solvespace can export STL or STEP files for a third-party CAM program. The user interface is quirky but more simple than FreeCAD. It allows you to create 3D parts like FreeCAD but, because it’s got a somewhat limited custom CAD kernel, it is better suited to mechanical-looking parts that don’t have highly sculpted, organic surfaces. Solvespace is another freeware 3D CAD program that’s got an almost cult-like following. In addition to it being freeware, if you really want to nerd out on CAD then the source code for FreeCAD is freely available.įreeCAD runs on Mac, Windows, and Linux.

The output from FreeCAD, STL, STEP, SVG, or DXF, can be sent to any of the CAM programs listed below. It’s not necessarily what we’d recommend for a beginner, but it is free, so there’s no cost to try it. Like Alibre, it’s capable of creating very complicated designs with very high precision, but the user interface is much more complicated, and the learning curve will be much more difficult. FreeCADįreeCAD is a completely free 3D CAD parametric program that’s become increasingly popular as 3D printers have become more popular. Luckily there have been significant improvements in the free options over the past few years as 3D printing, which uses the same CAD program, has taken off. There are many CAD software packages out there, but unfortunately, most of them are not free. Free CAD softwareĬAD, which stands for Computer-Aided Design, is the CNC software that lets you draw your designs. We’ll limit our listing to software for a CNC router or CNC milling machine and avoid other machine types, like plasma cutters and laser cutters. You may spend more time with the software than your CNC mill, so it’s worth spending a few dollars if the paid software makes CNC machining easier. We’ll cover a few paid products in addition to free options. CNC control software (Makes your machine follow the g code tool path).CAM Software (Lets you turn the drawing into a tool path in g code format).Starting from your design to the g code for your CNC machine, you’re going to need several CNC software applications:
