In the previous article, we’ve talked about the basics you need to know about 3D printing. Next we will discuss where you can get 3D models and download STL files for free. While many models are available to purchase, there are plenty of free models and STL files you can get for free. It’s an easy, time-saving way to get started on your 3D model adventures.





All3DP is a website that provides information and resources on 3D printing. The site includes articles, tutorials, and a reviews section where they review 3D printers and 3D modeling software. The website has a "Basics" section where you can learn the fundamentals of 3D printing and a "Pro" section where you can dive into more advanced topics.
All3DP also includes its own online 3D printing service, CraftCloud. Whether you are designing complex 3D models or just simple ones, or you want to 3D print but don't have a 3D printer, you can simply use CraftCloud.


2, Thingiverse



Thingiverse is a popular website for 3D printing models and it’s completely free. It is a place where users are able to not only share their own individual pieces of work but also both acquire and mix other users’ work too.
Thingiverse also strives to ensure that all the 3D models presented here are licensed under their own creative commons license. In fact, this is the guiding spirit behind maintaining this open platform. This means that just about anyone can either use or alter the models, designs and free STL files present here.


3, YouMagine



On YouMagine, designs are gathered into collections, which is another way that you can search for new projects. It contains over 19,000 free and open models, free STL files, and designs for 3D printing. YouMagine is a great way to start your search for your very first 3D printing project. Even if you are an expert in the art and science of 3D printing, you can still learn a lot from the community here.


4, Thangs



On Thangs you can search for models based on similar geometric shapes, so it’s like a searching engine. You can upload a prepared STL file to the search box, or simply type a shape into the search engine. On each model page, neat viewing options can be changed to display the model from different angles, and with render modes and colors, before downloading the files. This website also allows you to limit your search for models only to the Thangs website, or else open the search to other sites on the internet.
