Navigating the world of 3D design for 3D printing can feel overwhelming, especially when transitioning from simpler 2D software. The jump to 3D introduces complexities, but selecting the right CAD software is crucial for a smoother experience. The good news is that there are excellent free options available to get you started and designing effectively.
When it comes to robust Computer-Aided Design (CAD) software for 3D printing, Fusion 360, OnShape, and SolidWorks are often cited as industry leaders. SolidWorks, once considered too expensive for hobbyists, now offers more accessible licensing. Fusion 360 is a popular choice, though some users have noted performance dips on certain hardware over time. These programs generally follow a similar workflow: begin with a 2D sketch and then extrude it into a 3D shape. Sketches can be created on various planes, including faces of already extruded forms, offering flexibility in design.
While Google’s SketchUp enjoys broad popularity, it is less frequently recommended for precise 3D design intended for 3D printing. The reasons aren’t always clear, but it may lack some of the parametric control and features favored for engineering-focused 3D printing tasks.
For beginners, TinkerCAD presents itself as a very accessible entry point. FreeCAD and OpenSCAD are also free options, appealing to those seeking open-source solutions. However, these beginner-friendly programs often come with limitations that you might quickly encounter as your projects become more ambitious. Starting with software you plan to use long-term is often more efficient. Redesigning projects from scratch in new software due to the limitations of beginner tools can be a significant source of frustration.
For many, OnShape and Fusion 360 stand out as top contenders in the free CAD software space. While other capable programs might exist, often they are less established or lack the same level of community support and long-term reliability. For cloud-based solutions especially, the stability and longevity of the software provider are important considerations. SolidWorks, a long-standing industry standard, offers the advantage of desktop operation, potentially appealing to users who prefer to avoid cloud-dependent software, though it is Windows-based.
Ultimately, both OnShape and Fusion 360 boast extensive online learning resources, vibrant user communities, and are actively developed. This wealth of support is invaluable when learning and troubleshooting. Choosing software with strong community backing ensures you have access to help and inspiration as you progress in your 3D printing journey.
