The 4 Best Websites for Free 3D Printing Files
By Amir M. Bohlooli
Explore these 3D printing websites to find the best 3D models to download for free.
Having access to a 3D printer is a rather exciting privilege. Whether you've only just got your hands on one or a 3D printing veteran, free 3D printing models are always welcome. Designing a 3D model from scratch requires time and skill that you might not have.
There are lots of websites and libraries where you can download free 3D models, but not every 3D model is 3D printable. Below, you will find the four best websites for downloading free 3D printer files.
https://www.thingiverse.com/thing:5234703/comments Thingiverse is the ultimate 3D printing library. This website is entirely dedicated to 3D printers, and most 3D models are uploaded as STL files that can be easily 3D printed. Each model comes with a 3D preview, pictures of the printed product, and print settings.
Thingiverse allows users to post photos of their makes, and creators can remix other 3D files and create new designs. You can look through the different user-published makes to find the best print settings for a file, or to get some inspiration.
One major point which makes Thingiverse the most popular 3D printing library among makers is that it is entirely free. Every file that you see on Thingiverse, you can download and use for free. On the other hand, if you're a creator, you cannot monetize your models on Thingiverse.
Though you don't need to pay any money to use the free 3D models on these websites, it doesn't mean that they're not copyright protected. Do your research before using these files in commercial projects!
MyMiniFactory is a 3D printing community and library where you can find thousands of free and paid 3D models for download. MyMiniFactory has a strong emphasis on role-playing games, such as D&D.
Most of the models you'll find here are structures and characters designed for tabletop games.
If you're into printing tabletop figures, then you must have noticed by now that they look drastically better when printed in more than one color. Learn to bring more life to your prints by creating duotone prints.
MyMiniFactory has many community elements. Makers can write their stories in Community Stories, and they can partake in designing and printing competitions to win prizes. The site also hosts an ambitious project called Scan The World, whose goal is to offer art and heritage sculptures in the form of 3D printable files for free. So far, this project has cataloged 17,000 objects which you can download for free.
Cults is another 3D repository and community where you can download 3D models and print them. The site contains both free and paid models, and if you're a maker you can monetize your 3D model on Cults.
If you take a quick look at Cults, you'll realize that it's more oriented towards aesthetic and decorative models, rather than functional ones.
Cults has a wide array of jewelry, art, and fashion models. If you're looking to make your own 3D printed jewelry, it's a good place to browse and download models.
Cults also hosts 3D printing contests where you can design a model according to the given guidelines to win a prize.
TurboSquid is a massive marketplace for 3D models. While some of these models are designed to be 3D printed, most are not. However, that doesn't mean that you can't print them with a little tweak.
TurboSquid contains paid and free professional 3D models. You can find some extremely detailed and realistic models available on the site, such as vehicle models, people, and animals.
You can find 3D printable models by searching for STL models. There are roughly 80,000 STL models available on TurboSquid, which was acquired by Shutterstock in 2021.
From Bytes to the Real World
3D printing is an awesome technology that lets you bring 3D creations out of your computer and into the real world.
With a 3D printer, you can print any STL model, and you can get these STL models from the websites mentioned in this article.
Though you have to pay to download some models on these websites, there's still a good variety and quantity of free 3D models available. Now all you need to do is to find the model you like most, and get to printing!

Top 20 Free 3D Printing & 3D Printing Software
Looking for 3D printing software? We've rounded up the top 20 software tools for beginners and professionals alike.
Most slicers are free.
What is a slicer? This is a program for preparing a digital model for printing. Models for 3D printing are usually distributed in STL files. To turn an STL file into G-code (a language that a 3D printer understands), a slicer program is required. It is called a slicer because it cuts (to slice - English) a 3D model into many flat two-dimensional layers, from which a 3D printer will add a physical object.
Which slicer should I choose? In this article, we will tell you which slicer is best for 3D printing for each stage of your work. Which one is better for preparing a 3D model for printing? But what if you need to create a 3D model from scratch? And if you are only taking the first steps in 3D?
Don't be afraid: we've answered all of these questions, including the required skill level for each program and where you can download it. The great thing is that most of these programs are completely free and open source.

#1: Cura
For beginners who need a slicer to prepare STL files for 3D printing
Cura is the default slicer software for all Ultimaker 3D printers, but can be used with most others , including RepRap, Makerbot, Printrbot, Lulzbot and Witbox. The program is completely open source, its capabilities can be extended using plugins.
This program is very easy to use and allows you to manage the most important 3D printing settings through a clear interface. Start in Basic mode to quickly get up to speed and change print quality settings.
If finer control is required, switch to Expert mode.
Cura can also be used to directly control the printer, but then the printer and computer must be connected to each other.
Download: Cura
Price: Free
Systems: PC, Mac, Linux
#2: CraftWare
3D printers by the Hungarian startup CraftUnique to support their CraftBot crowdfunding machine. However, the program works with other printers.
Like Cura, CraftWare allows you to switch from "Easy" to "Expert" mode, depending on how confident you feel. It's a colorful app that features a visual G-code visualization with each function represented by a different color. But the most outstanding feature is the individual support service. As far as we know, only the paid program Simplify3D has this.
Please note, however, that this program is still in beta, so bugs may occur.
Download: CraftWare
Price: Free
Systems: PC, Mac
#3: 123D Catch
-systems, smartphones and tablets, which allows you to convert images of objects into a 3D model.
Pictures can be taken with a smartphone/tablet or digital camera.
You need many photos of an object from different angles - the more the better - after which they will be compiled into a 3D model.
123D Catch is more of a fun app than a professional 3D printing tool, but after some tambourine dancing, you can get good results, especially when paired with an STL editor like MeshLab or Meshmixer.
Price: Free
Systems: PC, Android, iOS, Windows Phone
#4: 3D Slash
and surprisingly simple, and refreshingly new. With 3D Slash, you can design 3D models using your dice skills.
You can start with a large block and, like a virtual sculptor, remove small cups from it with tools such as a hammer or drill, or start from empty space and build a model from cubes and other shapes. You can paint with flowers or use template pictures.
Other features worth mentioning are tools for creating logos and 3D text. The Logo Wizard imports an image and creates a 3D model, while the Text Wizard allows you to enter and format text, and then turn it into 3D.
Recommended!
Download: 3dslash.net
Price: Free
Systems: PC, Mac, Linux, browser
#5: TinkerCAD
- A computer-aided design (CAD) system for 3D printing, which is a good starting point for beginners. Since its capabilities are limited compared to Blender, FreeCAD and SketchUp, many users switch to more powerful tools after some time.
As in 3D Slash, here you can build models from basic shapes. At the same time, unlike 3D Slash, TinkerCAD allows you to create vector shapes in 2D and convert them into three-dimensional models.
Come in: Autodesk TinkerCAD
Price: Free
Systems: Browser
#6: 3DTin
For beginners who want to create 3D printable models
another easy and intuitive online tool choice for beginners in 3D modeling. All you need is a Chrome or Firefox browser with WebGL enabled.

Enter: 3DTin
Price: Free
Systems: Browser
#7: Sculptris
For beginners who want to create 3D printable models
clay. This is a fantastic 3D modeling program if figurines are your main task. For example, you can make a bust of your favorite video game or comic book character. Sculptris is completely free and bills itself as a stepping stone to the more complex (and expensive) ZBrush tool.
Download: Pixologic Sculptris
Price: Free
Systems: PC, Mac
#8: ViewSTL
For beginners who want to view STL files
ViewSTL is the easiest way to view STL files . Simply open a web page and drag the STL onto the dotted box.
The STL online viewer allows you to display the model in one of three views: flat shading (for a quick view), smooth shading (for a high-quality image), and wireframe.
Enter: ViewSTL
Price: Free
Systems: Browser
#9: Netfabb Basic
some nice features that allow you to analyze, "repair" and edit STL files before moving on to the model cutting stage.
A good choice if you need more than just a slicer and want to be able to quickly fix STL files without having to learn programs like MeshLab or Meshmixer.
Don't let the 'Basic' in the title fool you, Netfabb Basic is actually a very powerful 3D printing tool. It's "basic" only in the sense that it doesn't cost €1,500 like Netfabb Professional!
Download: netfabb.de
Price: Free
Systems: PC, Mac, Linux
No. 10: Repetier
For advanced to prepare STL files for 3D printing
9002 the next level of 3D printer slicer software, but if you want to stay open source, you should look into Repetier. It is the great grandfather of 3D printing software and a favorite of the RepRap community. To date, the program is moving by leaps and bounds from the level for beginners to advanced users.
Packaged in an all-in-one configuration, it supports up to 16 extruders, multi-slicing via plug-ins, and virtually every fusing 3D printer on the market. Get ready to tinker!
What's more, Repetier Host works remotely via Repetier Server, so that the 3D printer can be controlled via a browser, tablet or smartphone.
Download: Repetier
Price: Free
Systems: PC, Mac, Linux
#11: FreeCAD
The program is a great option for developing your design skills. More technically, this parametric 3D modeling program allows you to easily change the project by rolling back through the history of the model and editing the parameters.
Download: freecadweb.org
Price: Free
Systems: PC, Mac, Linux
#12: SketchUp
For beginners who want to create 3D printable models
SketchUp is the perfect combination of simplicity and the perfect combination functionality, with a user-friendly interface and a relatively flat learning curve (i.
e., as experience grows with the time spent), the ideal program for developing three-dimensional models.
The Make SketchUp version is free and will include everything you need for 3D modeling if you also download and install the free STL exporter. There is also a professional edition for architects, interior designers and engineers.

#15: Simplify3D
For professionals to prepare STL files for 3D printing print. A flexible algorithm checks the model for problems, fixes them, shows a preview of the printing process (ideal for identifying potential problems), and then slices it.
This slicer offers the best infill pattern options in the competition. For models that require supports, Simplify3D will create the appropriate structures on its own and give you full control over their placement. For printers with a dual extruder, when printing with different materials, the Dual Extrusion wizard will help, as a result of which, for example, it will be easier to remove the dissolving filament.
Simplify3D supports 90% of today's commercially available desktop 3D printers and is compatible with Marlin, Sprinter, Repetier, XYZprinting, FlashForge, Sailfish and MakerBot firmware. Simplify3D can also be used to directly control the printer, but then the printer and computer must be connected to each other.

#16: Slic3r
source code, which has a reputation as a carrier of super new functionality, which you will not find anywhere else. The current version of the program is able to show the model from multiple angles, so that the user gets a better preview experience.
There's also an incredible 3D honeycomb infill, the first of its kind that can extend over multiple layers rather than repeating itself like a stamp. This significantly increases the strength of the internal filling of the model and the final printout.
Another option is direct integration with Octoprint. Once the files on the user's desktop are sliced, they can be directly uploaded to Octoprint with one click.
Download: Slic3r
Price: Free
Systems: PC, Mac, Linux
#17: Blender
For professionals who want to create 3D printable models
Blender is a popular computer-aided design (CAD) system with a steep learning curve.
Not at all the best choice for beginners, but what you need if you are quite experienced and need something more complex for modeling and printing.
In short, Blender is one of the most powerful tools out there. Its community is always ready to help, there are a lot of educational materials. It's also open source, so enthusiasts often write extensions to make it even better and more powerful.
Download: blender.org
Price: Free
Systems: PC, Mac, Linux
#18: MeshLab
For professionals to prepare STL files for 3D printing
MeshLab - advanced editor. It allows you to remove parts of a 3D model, merge two models into one, patch holes. If you need a program to modify models for 3D printing or some kind of "repair" work, MeshLab is the right choice.
Price: Free
Systems: PC, Mac, Linux
#19: Meshmixer
For professionals to prepare STL files for 3D printing files. It's especially good for identifying potential problems and fixing them automatically.
For example, it will show paper-thin walls that can lead to problems with 3D printing. Meshmixer is part of the Autodesk family of 3D printer software, so it should work well with tools like TinkerCAD.
Price: Free
Systems: PC, Mac
#20: OctoPrint
start, pause or interrupt 3D print jobs. Combined with Wi-Fi capable devices, it makes for an excellent monitor for remotely monitoring the 3D printing process.
