3D printing is a new technology that can be used across several subjects in school including creativity, math, art, science and ICT. The potential benefits of 3D printing outweigh the risks, and there are risks to not becoming involved with the technology. The document provides instructions for designing a 3D model using software, converting it to an STL file, slicing it, and then printing the model using a 3D printer. It also lists some free 3D modeling programs and websites where 3D models can be found.
