Need recommendations for best free CAD software for 3D printing

I’ve just bought my first 3D printer and I’m excited to start making things, but I’m a bit overwhelmed by the options for CAD software. I’m looking for something that’s free, easy to use for a beginner, and works well for 3D printing. Any suggestions?

For beginners diving into the world of 3D printing, I’d recommend checking out Tinkercad. Super intuitive, completely free, and web-based, so you won’t need to install anything big. It’s perfect for newbies to jump in and start creating simple to moderately complex objects. Once you get the hang of it, you can always graduate to more advanced options.

Also, Fusion 360 is solid. It’s free for personal use if you fall into the hobbyist category. Offers a ton more when you’re ready for it—powerful modeling tools, simulations, and more. The learning curve is steeper than Tinkercad, though.

Onshape is another one that’s worth mentioning. Free for individuals with the public plan. Cloud-based, so you can access your designs anywhere. More sophisticated than Tinkercad, not as heavy-duty as Fusion 360.

Can’t forget Blender, a bit trickier for beginners but it’s free and incredibly versatile. Not just limited to CAD; you can use it for animations and other cool stuff if you’re into that. There’s a steep learning curve though, so might not be the very first tool you’d want to start with unless you’re up for the challenge.

If you’re specifically aiming for 3D printing, keep in mind that the software should allow you to export STL files, which is the standard format for 3D printing. All the mentioned software supports this.

Don’t dive too deep into the software rabbit hole just yet. Start simple, focus on getting a few projects done. Experience will guide you to what you need next.

Hope this helps! Happy printing.

It’s fantastic that you’re getting into 3D printing! I can’t agree more with @sognonotturno about Tinkercad for beginners—it’s super user-friendly and doesn’t require a download, which makes it a smooth entry point.

However, if you’re looking for something that gets you used to a professional workflow without feeling overwhelmed, FreeCAD could be a solid choice. It’s open-source, free, and despite having more features than Tinkercad, it’s tailored for 3D designing, parametric modeling, and more. It might seem a tad technical initially, but you get a more realistic taste of what the professionals use.

On the other hand, if you need a complete CAD and slicing suite, consider looking at PrusaSlicer. While primarily a slicer used for 3D printing, it also has basic CAD features and supports a wide range of 3D printers, making it a versatile tool once you get the hang of simple designing.

And hey, I slightly disagree about Blender. It’s super powerful, but for the absolute newbie, it can feel like jumping in the deep end—especially if you’ve never used 3D software before. It’s great for learning the ropes of complex modeling, but perhaps not the best initial dive.

Another handy option to try is SketchUp Free. Not traditionally targeted for 3D printing specifically, but its intuitive interface makes creating basic models straightforward. Plus, it runs in the browser, no installs necessary. A caveat: you’ll need to make sure to export your designs in STL format for printing. SketchUp’s simplicity, though, can be restrictive for complex designs down the line.

Don’t forget about the importance of exporting STL or OBJ files for 3D printing. Whatever you choose should comfortably support these formats to make your life easier. Start with simpler projects, focus on learning the device-specific slicing settings (which can be a challenge in itself), and gradually you’ll get a better sense of what software best suits your growing needs.

Lastly, an often-overlooked gem is Librecad for 2D CAD needs that could complement your 3D endeavors. Though not a direct CAD tool, its use as a side tool for details can be invaluable.

Explore, experiment, and you’ll naturally gravitate towards what clicks for you. Enjoy the exhilarating world of 3D printing!

For someone dabbling into 3D printing, Tinkercad is indeed a neat entry-point. It’s free, intuitive, and web-based, making it perfect for beginners—you can easily get started without the hassle of installations. Being web-based is an underrated benefit, especially on devices with limited storage. Pros: simplicity, accessibility. Cons: it can feel restricting for more complex designs.

Fusion 360 and Onshape are excellent recommendations. Fusion 360 is a powerhouse with robust features, ideal when you’re ready for more advanced modeling. Similarly, Onshape, being cloud-based, provides flexibility and a professional feel. These tools have a learning curve, but the depth they offer is worth it for serious hobbyists. FreeCAD is another viable option here; it’s open-source and versatile, though maybe a tad technical starting out.

However, I think you might also want to consider SketchUp Free. This tool is browser-based like Tinkercad, and while not specifically designed for 3D printing, it’s intuitive and great for creating simpler models. One caveat: you’ll need to export to STL for printing. Pros: user-friendly, web-based. Cons: limited for intricate designs.

On Blender, while powerful and versatile, it’s a steep climb for a newbie. Definitely avoid as a first tool unless you’re really up for a challenge and okay with a slow ramp-up. Pros: versatility, free. Cons: huge learning curve for newcomers.

Interestingly, PrusaSlicer has basic CAD features you might find helpful. Primarily a slicer, it’s handy for someone just beginning, allowing you to combine CAD and slicing needs in one tool. Pros: slicing and basic CAD in one. Cons: limited CAD functions compared to standalone CAD software.

Someone mentioned Librecad, which can complement your work with 2D CAD needs, though it’s not directly a 3D tool. Useful, but perhaps not essential right off the bat.

In summary, Tinkercad is solid for starting out. As you get more comfortable, Fusion 360, FreeCAD, and Onshape are great next steps. SketchUp Free and PrusaSlicer offer unique perks worthy of consideration. Definitely experiment to see what clicks for you. Happy creating!
