Recommended reading: How to find free STL files Overall, contemporary design software offers a huge variety of features that help users create stunningly detailed 3D models. Typically, users can choose between 2D or 3D design views. Some users make their own 3D designs by drawing and modifying geometric shapes on-screen, but models can also be algorithmically generated. CAD applications are powerful tools that allow for the creation of very complex 3D designs. But 3D printers can only work with digital instructions.ģD models for printing are made using computer-aided design (CAD) software. Compare 3D printing to machining, for instance: machines like mills or lathes can either use computer numerical control (with a 3D model providing the instructions) or be operated manually, without any digital foundation at all. This isn’t the case with all manufacturing processes. Knowing how to make a 3D model for printing is very important, since there is no other way to create printed objects. The outcome of the print is a physical representation of the digital 3D model. Every print begins with a digital model designed using CAD software, which is then converted or “sliced” into instructions that can be understood by the 3D printer. These websites offer a one-stop solution and take away the hassle of individually searching for the model on different websites.3D models are the foundation of 3D printing. Last, we have included search engines that let you search for a specific model across many sites at once. Usually, these websites are great places to get premium models and you can even directly request the creator to create a specific model for your needs. You get access to premium models that you can purchase for a particular fee. Marketplaces are websites that let you buy and sell STL files or 3D models. Most of the websites mentioned in this list are repositories. Depending upon the particular website, you might need to create an account to download these files. These files are free to download for anyone.

We’ve sorted out all the websites in three different categories: Repositories, Marketplaces, and Search Engines.Ī repository is a place where you can get a large collection of free STL files. To get the full benefit of this list, it helps to understand the differences between the various websites.
