Mar 9, 2016 | By Kira
We've already covered the best sites to download free STL files to 3D print, but if you want to create a unique or purpose-built 3D printed object, there's no better option than modeling it yourself. Whether you are an absolute beginner or a 3D design pro, you can easily create your own custom 3D printable models using 3D modeling software—and best of all, some of the most popular ones out there are absolutely free.
To help sort through them by type, accessibility, and technique, we've assembled a list of some of the best and most popular free 3D modeling programs for 3D printing:
Free 3D modeling software #1: TinkerCAD
- Free CAD 3D modeling tool
- Best for Beginners
- Browser-based online app
- Geometric 3D modeling
- Made by Autodesk
For absolute 3D modeling beginners, Autodesk's TinkerCAD is a great place to start. The browser-based 3D modeling software lets you create geometrical 3D shapes, save and share them online, and export them to .STL files when ready to 3D print. Though obviously a bit limited in terms of features (you won't be 3D modeling a Michelangelo statue with this), TinkerCAD is excellent for, well, tinkering. And since shapes are the building blocks, users can gradually build up from simple to more complex or detailed forms. For inspiration, TinkerCAD offers some existing 3D shapes to start modeling with, as well as a gallery of finished 3D printable models.
Free 3D modeling software #2: 3DSlash
- Free CAD 3D modeling software
- Best for Beginners
- Browser-based or available for Windows, Mac, Linux and Raspberry Pi
- Geometric 3D modeling
- Made by 3DSlash
Another great and free option for beginner 3D modelers is 3DSlash. Released just last year, 3DSlash was designed specifically for non-designers of all ages—including kids—to introduce 3D modeling concepts in a fun and game-like platform (in fact, 3DSlash is actually based on Minecraft.)
In 3DSlash, users use common tools, like hammers or chisels, to shape three-dimensional blocks. The three-step process is intuitive, colorful, and fun, and in the end, the 3D model can be shared online, or exported to .STL for 3D printing. 3DSlash V2.0 has recently been released, and the website features extensive 3D modeling video tutorials that are definitely worth checking out.
Free 3D modeling software #3: 123D Design
- Free CAD 3D modeling app
- Best for Beginners
- Free download for PC, Mac and iPad
- Geometric 3D modeling
- Made by Autodesk
123D Design is another free 3D modeling software option by Autodesk. Though slightly more advanced than TinkerCAD, 123D Design is still a very simple and intuitive 3D modeling and editing tool. There is a pretty extensive library of pre-made 3D models that can be edited, as well as tools to create geometric 3D components from scratch. Like with TinkerCAD, finished 3D models in 123D Design can be exported to .STL for 3D printing, or uploaded directly Shapeways' 3D printing service.
Free 3D modeling software #4: Sketchup
- Free CAD 3D modeling software
- Best for Intermediate 3D Designers
- Free download for PC, Mac, or Linux
- Line and curve-based 3D modeling
- Made by Trimble
Moving into slightly more advanced free 3D modeling tools is Sketchup. Originally owned by Google, Trimble's hugely popular Sketchup markets itself as the 'friendly and forgiving' 3D modeling software. It starts with a simple interface yet integrates a huge range of functional add-ons and tools. Users start by drawing lines and shapes, which can then be pushed and pulled into a range of complex geometric 3D forms. Because of this line-based 3D modeling set up, Sketchup (and particularly its $695 Pro version) is popular amongst architects and engineers.
Just because Sketchup is used by professionals and even educators, doesn't mean it's not a safe place to start for beginners, too. After all, it's totally free to experiment with, and the website offers 3D modeling video tutorials to get you started. While Sketchup is a 3D modeling favorite, an important note for makers is that you can only export 3D printable .STL files using in the paid version.
Free 3D modeling software #5: Blender
- Free CAD 3D modeling software
- Best for Advanced or Professional 3D Designers
- Free download for PC, Mac, or Linux
- 3D Digital sculpting tool
- Open Source
Blender currently holds the title for being the most powerful and the most popular free 3D modeling software—but be warned, it's not for beginners. Unlike geometric 3D modelers, Blender is a digital sculpting tool, making it ideal for creating more organic 3D shapes. The program also offers a dizzying array of tools, giving its users complete design freedom: beyond creating models for 3D printing, Blender can be used to create photorealistic video game graphics, animated films, visual effects and more. Basically, if you're willing to put in the time to learn it (which is made easier by the vast amount of forum discussions and tutorials created by the open source community), Blender could be your 3D modeling choice for life.
Free 3D modeling software #6: 3DTin
3D model by Germán
- Free CAD 3D modeling software
- Best for Beginners
- Browser-based online app
- Geometric 3D modeling
- Made by Lagoa
Getting back to basics, 3DTin is a free, browser-based 3D modeling tool that, like TinkerCAD and 3DSlash, was created for beginners and those with no previous 3D modeling experience. Users choose from a selection of geometric shapes and add or remove as needed to create their design. Once finished, they can add their 3D model to 3DTin's extensive library of Creative Commons 3D models, a valuable resource for students and beginners. 3DTin also allows direct exporting of .STL files to i.Materialise, Thingiverse, or Sculpteo for easy 3D printing. Note that 3DTin requires the JavaScript API WebGL to run at its best.
Free 3D modeling software #7: Sculptris
- Free CAD 3D modeling software
- Best for Beginner to Intermediate 3D designers
- Free download for Windows or Mac
- 3D Digital sculpting tool
- Made by Pixologic
Like Blender, Sculptris is a digital sculpting tool, which makes it ideal for 3D modeling organic shapes and textures just as you would with a physical chunk of clay. In ‘sculpt' mode, users edit the mesh geometry of their 3D shape, and in ‘paint' mode, they can use various brushes to create realistic textures on the surface. Sculptris was designed to offer beginners the chance to experiment, get their bearings, and grow into their newfound 3D modeling skills. While a great option as a standalone product, advanced users can also upgrade to ZBrush, Pixologic's award-winning, professional 3D modeling software, which comes at the price of $795.
Free 3D modeling software #8: Meshmixer
- Free CAD 3D modeling software
- Best for Beginner to Intermediate 3D Designers
- Free download for Windows, Mac or Linux
- 3D triangle mesh modeling
- Made by Autodesk
While all of the CAD modeling tools on this list support 3D modeling for 3D printing applications, Meshmixer is perhaps the most powerful in this regard, as it has features created specifically to facilitate the digital-to-physical experience. In particular, Meshmixer is extremely useful for correcting files created in other 3D modeling programs or imported from Autodesk's 123D Gallery, allowing users to 3D print with confidence. Along with previewing, refining and correcting existing 3D models, Meshmixer is a powerful tool for creating organic 3D models from scratch using triangle meshes.
To further facilitate the 3D printing process, Meshmixer supports many desktop 3D printer models, or, users can choose to import their designs directly to Shapeways, Sculpteo, or i.materialise to be professionally 3D printed and delivered. Its latest iteration even has optimized tools for multimaterial 3D printing. In short, Meshmixer is a powerful and free 3D modeling tool for beginners and intermediate designers who want to successfully bring their creations into the real world via 3D printing.
Free 3D modeling software #9: FreeCAD
- Free CAD 3D modeling software
- Best for Intermediate to Advanced 3D Designers
- Free download for Windows, Mac or Linux
- Parametric modeling
- Open Source
FreeCAD's parametric modeling interface is ideal for engineers or more advanced product designers looking to make complex, functional, and real-life 3D printed objects. Unlike standard mesh modeling, parametric (or procedural) modeling is a more algorithmic method that allows the object to be quickly and efficiently edited by accessing the model history and changing its parameters. FreeCAD's extensive range of professional-grade features also gives users nearly unlimited design freedom—albeit, it does come at the cost of a much steeper learning curve than most free 3D modeling tools. That being said, FreeCAD's large community is quite welcoming to new or inexperienced designers looking for a powerful point of entry to functional 3D design.
Free 3D modeling software #10: OpenSCAD
- Free CAD 3D modeling software
- Best for Programmers
- Free download for Windows, Mac or Linux
- Parametric modeling
Like all of the 3D modeling software tools on this list, OpenSCAD is a reliable, free program for creating solid, 3D printable models. Unlike most others, however, OpenSCAD is a non-visual 3D modeling tool, making it ideal for coders rather than purely artistic types. Instead of visually molding, sculpting, pushing, and pulling 3D shapes on-screen, OpenSCAD works 'like a 3D-compiler,' reading a script file written in programming language, and then rendering a 3D model from that script.
OpenSCAD's parametric modeling allows for easy editing and precise control over the 3D model's properties. The program also allows 3D models to be exported to .STL format for easy 3D printing. OpenSCAD may not be for everyone, but as one of the only non-visual 3D modeling tools, it fulfils an important role in the market.
Bonus: Onshape
- (Limited) Free CAD 3D modeling software
- Best for Beginner to Professional 3D designers
- Browser-based online application; also available for iOS and Android
- Parametric modeling
Onshape is still a relatively new 3D modeling program, and the free account does come with a few limitations. However, Onshape offers some very unique and professional-grade 3D modeling features, including real-time, team-based 3D design, making it a unique option for professional engineers to classroom students.
Onshape is a parasolid-based mechanical CAD 3D modeling program for creating complex parts and assemblies. The fully cloud-based platform can be accessed from a variety of devices, including iOS and Android smartphones, and allows multiple team members to simultaneously collaborate on the 3D design. Additional features include full CAD functionality, version control, and unlimited import and export for 3D printing. Additionally, both Materialise and Pinshape have joined Onshape as 3D printing partners via their respective apps.
The only limitations of the free account are that users are limited to 10 private documents and 5GB of storage. If that's not enough, professionals can choose to upgrade for just $100/month.
These are just some of the most popular and reliable 3D modeling software tools available completely for free, however there are plenty of other free and paid options for all levels of 3D designers. It's just a question of getting started, and finding which one works best for you.
Mac dual boot software. Note that 3D modeling software is just the beginning: In order to successfully 3D print your design, you will also need STL viewing software, slicing software (to prepare the 3D model) and 3D printer host software. A few free options to get you started are Netfabb Basic, View STL, Cura, and Slic3r.

I have to agree with the other comments, Designspark Mechanical is a very nice tool, with some strange limitations for the free version, but still very usable. I do like the Spaceclaim direct modelling approach and would love to get a full license at some point (used the trial version once) but it's too expensive for my hobby use. And if you mention OnShape, you should have written something about Fusion 360. VERY powerful tool you can use for free, with the bonus that it has a CAM module included to plan milling paths for your desktop CNC.. (And i prefer the interface of F360 over OnShape)

DesignSpark Mechanical: fantastic package, we've used it extensively to prepare models. Solid modeler..a few limitations, one bizarre, one understandable. The bizarre: no mirroring in 3D! Workaround is to export to an STL, mirror elsewhere, then reimport. That's clunky, I know. Understandable: to IGES or STEP export unless you pay for an expensive plugin. Highly, highly recommend this program. Another option: Autodesk Fusion360. No idea why either of those were overlooked here.

Any thoughts about the free version of DesignSpark Mechanical?
I bet Nike ZoomX Vaporfly Next%, the 3D printed marathon shoes, must've motivated you to build something cool. It's only wise that you would want to try a 3D printing software before investing in a 3D printer. However, choosing a good free 3D printing software can prove to be a hassle. There are too many options where each caters to a diverse range of applications.
To make things a bit simpler, we've compiled a list of the best 3D printing software for beginners. But before we take a look at the list, there's one thing you should know. If you're already using Photoshop, then you can get started right away. Photoshop also lets you create 3D models from scratch and print them using services like Shapeways 3D.
Also on Guiding Tech How to Use Netfabb to Measure STL Files on Windows Read More1. TinkerCAD
Kicking off the list is TinkerCAD, an online 3D design application which is perfect for beginners. It makes use of a simple block building concept, which essentially gives you access to basic shapes using which you can make your 3D models. That makes it an excellent tool for creating geometric designs.
TinkerCAD is fairly simple to get familiar with, and it also offers a bunch of amazing tutorials to speed up the learning process. Once you're done making a model, it lets you share or export the file easily.
And if you don't own a 3D printer, you can also make use of its third-party printing service integration to get your model delivered to your doorstep in no time.
Try TinkerCAD2. Cura
Design 3d Llc
Next up is Cura, another great 3D printing application for beginners from Ultimaker, a leading manufacturer of 3D printers. Unlike TinkerCAD, Cura is a slicing software for 3D printers which you can use to create a 3D model and slice it into layers as G-Code for the printer.
On top of that, you can also use Cura as a failsafe measure for your models. It can let you know if there are any problems with your model's structure that might cause issues with the printing.
That feature is a blessing for beginners since it ensures that you don't waste any printing material or time on creating models with structural issues.
Try Cura3. Sculptris
While TinkerCAD is great for creating geometric designs, you should give Sculptris a shot if you want to create something a bit more organic. It's quite simple to use and offers a few key features that will help you create stunning 3D sculptures.
Working on Sculptris feels a lot like working with modeling clay, which makes it one of the best options if you're looking to create 3D models of things like cartoon characters; something that you can't do with TinkerCAD.
However, you'll only be able to create very basic 3D sculptures with Sculptris. You'll need to rely on other premium software like ZBrush to refine your designs later.
Try Sculptris4. SketchUp
If 3D sculpting isn't really your cup of tea and you'd much prefer software that relies on line drawings to help you create a 3D model, then you should try using SketchUp. The software is suitable for most skill levels as it has a natural learning curve. And once you get going, the software offers a couple of advanced features as well in the paid version.
Much like TinkerCAD, SketchUp is useful for creating geometric designs. The software is most commonly used for designing architectural projects. So if that's what you're aiming for, then you just can't go wrong with it.
The best part about using SketchUP is that it's also available as a web app. You can work on your design on any system as long as you have it saved on your account.
Try SketchUp5. Meshmixer
Meshmixer is another viable option if you're going to be sculpting organic models in 3D as it makes use of a triangular mesh to help you create smooth, even surfaces.
Just like Cura, the software also includes a feature which will help you check your model for holes and fix them in real-time.
Along with that, Meshmixer is also great for preparing your designs for 3D printing. It includes tools to slice the sculpture for the 3D printer, generate supports for structural integrity and even analyzes the design's fragility before you send it over for printing.
Try MeshMixer6. 3D Slash
Now if you're aiming for a retro, blocky aesthetic for your 3D models, then you should check out 3D Slash. The software allows you to upload your 3D model which it then breaks down into 3D building blocks.
You can then make any changes to the model using a variety of different tools. However, you will face some limitations in terms of functions in the free version of the software.
Along with the ability to pixelate just about any model, 3D Slash also offers a VR mode. You can use that mode to get a clear view of how your model will turn out using a VR headset. 3D Slash comes with one of the simplest user interfaces out of all the software on this list. That's what makes it a fantastic option for people of all ages.
Try 3D Slash7. FreeCAD
Rounding things off is FreeCAD, a parametric 3D modeling tool which will help you create precise geometric designs like replacement parts for your gadgets. The software isn't as good for creating new designs as it is for altering existing ones because of its parametric component.
Editing existing designs is fairly simple; you just need to head to your model history and change the parameters. It's that simple.
So if you're not hell-bent on creating your 3D models from scratch, then you should try FreeCAD. However, if you'd much rather create your custom model, then you'd be better off with either of the other options.

Create Amazing 3D Models
I hope you've got a fair idea of what you can achieve with these 3D printing software. How about you give them a shot and create your first 3D model? If you've tried your hand at 3D modeling, then I'd recommend to check out some tutorials these software have to offer to get started.
Just keep in mind that 3D printing can prove to be a pretty expensive hobby, so make sure you've inspected your designs thoroughly before you hit that print button. Why stop a shoe, when you can 3D print a dream home?
