What is 3D Printing?


Known in industrial circles as rapid prototyping, 3D printing refers to technologies that construct physical objects from three-dimensional (3D) digital content such as 3D modeling software, computer-aided design (CAD) tools, computer-aided tomography (CAT), and X-ray crystallography. A 3D printer builds a tangible model or prototype from the electronic file, one layer at a time, through an extrusion-like process using plastics and other flexible materials, or an inkjet-like process to spray a bonding agent onto a very thin layer of fixable powder. The deposits created by the machine can be applied very accurately to build an object from the bottom up, layer by layer, with resolutions that, even in the least expensive machines, are more than sufficient to express a large amount of detail. The process even accommodates moving parts within the object. Using different materials and bonding agents, color can be applied, and parts can be rendered in plastic, resin, or metal. This technology is commonly used in manufacturing to build prototypes of almost any object (scaled to fit the printer, of course) that can be conveyed in three dimensions.

(1) How might this technology be relevant to the educational sector you know best?

  • with the makers movement technology like 3D printers will be an important part in the teaching skills like critical thinking, innovation, math, scienc, ICT and more.

  • I think 3D could be a good support for the blind and other people who need a cognitive support to better understand their environment. For example, by printing a 3d over the place, designs and drawings.

  • When 3D printing is an ordinary part of a classroom i think it will bee a wery powerfool toll for innovatian, learning, modelling and exploration. One element is the form you are printing, with what material you are printing with may bee whats gonna change the future. - stefan.reppe stefan.reppe Nov 12, 2016- helle.mathiasen helle.mathiasen Nov 13, 2016

(3) What do you see as the potential impact of this technology on teaching, learning, or creative inquiry?

  • in Norway the entrepreneur class is very popular. 3D printing can add value here. It is an important skill for stu to be able to create. First with new ideas, trials and experiment. - Ann.Sorum.Michaelsen Ann.Sorum.Michaelsen Oct 24, 2016
