In order to print something on a 3D printer, you must have a 3D model. A 3D model is a digital file of an object created using software or 3D scanning. In simple words, this is a file in which all the “3D-shape” geometry of an object is specified, which must be printed by a 3D printer.

Typically, a 3D model is displayed as a 2D image using 3D rendering or rendering with the ability to rotate around a given point in the coordinate system.

It is not possible to launch a 3D printer without a 3D model. As it is, it is not possible to calculate the cost of 3D printing. This is very important to understand, because one of the most frequently asked questions is, “How much will it cost?” Dear customers, please understand that it is impossible to provide a calculation without a 3D model! If you would like to receive a quote, send or upload your 3D model to us. Where can you get it? We describe in this article.

Consider 4 methods for obtaining a 3D model:

  1. Creation of 3D models
  2. 3D scanning
  3. 3D modeling order
  4. Downloading 3D models on special resources.

Let’s take a closer look at the last point and take a look at a few of the main resources that I most often use to download 3D models for 3D printing:

  1. – a 3D printing marketplace where you can also buy a 3D model.
  2. – the main and largest resource of free models.
  3. – aggregator for searching 3D models from all over the Internet.
  4. – young but rapidly developing platform.
  5. – interesting resource with good user experience. They are excellent on Instagram.
  6. – good solution for engineers and designers. Analogue of ThingiVerse, just less popular, but no less functional.
  7. – an analogue of the second point, however, I found several necessary models for myself only here.
  8. – collection of 3D models from the manufacturer of 3D printers XZY.
  9. – for those who need solid CAD models.
  10. – very simple and convenient search by STL models.
  11. – if you need toys or dolls.
  12. – guys are developing interesting things. Many customers send models for printing from here.
  13. – models of space bodies and aircraft.
  14. – functional product models.
  15. – a library of models from the manufacturer of 3D printers Zortrax.
  16. – an excellent portal for selling 3D models with a convenient viewer.
  17. – 3D models for the pros. A large number of models for real projects.
  18. – a large number of 3D models of an individual format. This site is unlike any other.
  19. – resembles a search engine for 3D models. Essentially, it is a CAD catalog.
  20. – on this resource I found a lot of 3D models for the advertising industry. Many interesting things for microelectronics, working with light, etc.
  21. – marketplace of 3D models for household use.
  22. – 3D models for a wide range of applications.
  23. – 3D models at incredibly high prices. However, it also came in handy at work.
  24. – the most basic feature of this resource is free of charge.
  25. – 3D models from chemistry, medicine and education.
  26. – a selection of models from the leading manufacturer of 3D printers in Europe.
  27. – a selection of 3D models from the Russian portal of 3D printing.

As you can see, there are a lot of portals for searching 3D models. Which means how quickly and rapidly the technology is evolving.
