3D Printing

3D printing refers to the process of turning a digital design into a physical object. It allows you to "print" a 3D object layer by layer out of materials like plastic, metals or organic materials. In the past, 3D printing was primarily used by engineers for prototyping. Now with lowered cost and more advanced techniques, you can print out almost everything, including clothing, food and even replicas of human organs. To print in 3D, you first need to create a 3D model design. This can be done using either a 3D modelling software or through a 3D scanning tools.

Below are some additional resources for you to know more about 3D printing and 3D model design. 

3D Modelling Software

 •  Create a new model

To print something in 3D, we start by creating a 3D model design, usually in STL or OBJ format. Here are some tools that will help you build up your 3D model quickly. For beginners, we suggest starting with Tinkercad, a free and web-based tool that allows you to import vector graphics and turn them into 3D models.

 •  Check model before printing

Make sure your 3D model is seamless before print! Below are some tools that will help you check and repair the file to ensure your model is ready for printing.
