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?

  • This technology is brand new in my educational sector, but in the yars to coma i expect that it has a potential to becoma a great tool for education and ICT in the school. It is difficult to anticipate the ramifications, but when we have 3D printers and software at schools in a couple of years, ALOT of different uses will emerge. ¨- stefan.reppe stefan.reppe Sep 10, 2013- per.hetland per.hetland Sep 17, 2013This is especially relevant within STEM
  • This is probably one of the greatest inventions and could have geopolitical consequences, but in education I see obvious reasons to use this in natural science and technology and design. The pupils will be motivated by seeing and useing brand new technology and there are so many interesting ethical and political discussions you can have based on this technology. To make and produce something will be good for some pupils who like to work more practical. - nina.fjeldheim2 nina.fjeldheim2 Sep 11, 2013 - Liv.Dahlin Liv.Dahlin Sep 14, 2013- per.hetland per.hetland Sep 17, 2013Gives a possibilty to link practical and theoretical issues- vibeke.klovstad vibeke.klovstad Sep 23, 2013
  • The obvious use is in upper secondary where CAD is already used, but prototyping is difficult and costly. However, it'll be interesting to see how 3D-printing will bee used in elementary school in arts and crafts and maybe other areas. - snorre.lovas snorre.lovas Sep 16, 2013
  • I think this ties in nicely with the Maker Movement that is in some way about changing they way we work in schools. The mission of the Maker Education Initiative is to create more opportunities for young people to make, and, by making, build confidence, foster creativity, and spark interest in science, technology, engineering, math, the arts—and learning as a whole. Source: http://makered.org/about/ it has inspired educators to bring more hands-on learning into the classrooms. 3D printing will make it possible for students to produce something useful they might even sell. - Ann.Sorum.Michaelsen Ann.Sorum.Michaelsen Sep 16, 2013- vibeke.klovstad vibeke.klovstad Sep 23, 2013 I agree, 3D printing is a very nice bridge between the physical and the virtual/digital world. The Maker Movement should possibly be a topic in its own right? - morten.dahl morten.dahl Sep 23, 2013
  • Cheaper and better printers will innovate and inspire new ways of learning --- especially design and production. - morten.soby morten.soby Sep 17, 2013
  • Using 3D modeling software will probably take up most of the production time. Although programs like SketchUp are available for everyone, and used in elementary schools, the way we use these programs may change when the goal is to create real 3d models. Before the printers become more available teachers and pupils need sufficient training in a variety of relevant 3D software. SketchUp is being used in this video: How to design a model for 3D printing: http://youtube.com/watch?v=E-5bxZRmxgo&list=PLMXBH8t7SuGK_WcBMOnUjmY04cEjUdqJm&index=3 - Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • Qualitative assessment of pupils and teachers make up of the product, and its shape is important. Evaluation of 3D drawing is also relevant. > Relevance in several subjects: Science, art and craft, technology and design, mathematics etc.- Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • 3D printing will be relevant in a large number of subjects, especiallyin fields where there is a need to visualize and build to make students understanding stronger. 3D priting can also be used in multidisciplinary settings.- vibeke.klovstad vibeke.klovstad Sep 23, 2013 > 3D printing provide new possibilities for the materiality and creative processes of learning. Its materiality imply that teachers and students can experiment with material objects in new ways. It will also provide new possibilities to stimulate creative processes among students.- ola.erstad ola.erstad Sep 28, 2013
  • Very interesting technology that could contribute to the creative creation, and understanding in most subjects. Here, students can really create! As 3D printers are evolving rapidly, it is now possible to envisage such technology in schools shortly. - heidi heidi Sep 30, 2013

(2) What themes are missing from the above description that you think are important?

  • Ten years ago we didnt have tablets. Now all have them. Where will 3D printing technology be in ten years? Can we then print food? - stefan.reppe stefan.reppe Sep 10, 2013
  • Geopolitics; China has low labor cost - will that matter now that we can print it?- nina.fjeldheim2 nina.fjeldheim2 Sep 11, 2013
  • The possibility to promote and understand Universal Design- per.hetland per.hetland Sep 17, 2013
  • Using 3D modeling software as an important part of the work with 3D printing. - Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • The process of design / design and 3D print, namely "recognition programs" which checks that it is physically possible to carry out printing and fix any errors with 3D drawing: www.netfabb.com/education.php - Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • Currently, this is to expensive, and the individual school don't need to buy their own printer as long as they can order prints from elsewhere.- Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • I would very much like to read about/see more concrete examples of use of 3D printers into subject areas, otherwise the phenomena is difficult to explain. - vibeke.klovstad vibeke.klovstad Sep 23, 2013

(3) What do you see as the potential impact of this technology on Norwegian K-12 education?

  • It will be a "new" way for students to make physical objects, with much larger complicity than thay can now. What will happen when big groups of youth has acsess to this technology? We just cant know. - stefan.reppe stefan.reppe Sep 10, 2013
  • - sven.o.brekke sven.o.brekke Sep 11, 2013 In Bergen at the Vilvite senter they have a project called digital sløyd. See included link. this is not 3d printing, but it is 3d drawing in Sketcup and then a lasercutter that cut out the pieces that you can assemble afterwards. I think that is a great task for students. I do no think 3d printers will be a big issue in schools in the near future. It might take of industrially and challenge the production of products like shoes for instance, but I am not convinced that it will become a big thing in schools.
  • It's a new format for pupils to express themselves resulting in physical objects. Pupils have been restricted to sowing, woodworking and other physical materials. Not all pupils are good with their hands, either it is because of natural abilities, disabilities or something else. 3d-printing is another path where the pupil is more in control of the design and can refine it digitally before making the physical object. - snorre.lovas snorre.lovas Sep 16, 2013
  • I see a huge potential in making the work the students do in school more relevant and authentic. I think we need to answer the questions why do we need to learn this, and that we need to rethink a lot that is going on in the classrooms to make school more relevant for students. - Ann.Sorum.Michaelsen Ann.Sorum.Michaelsen Sep 16, 2013
  • A better understanding of design- per.hetland per.hetland Sep 17, 2013
  • To get exercise to develop accurate model sketching, and experience where you have to be in model development before the idea actually can be produced. Students can work in groups to create something more complex, consisting of several components that can be put together in the end.- Liv.Dahlin Liv.Dahlin Sep 22, 2013
  • 3D will help to visualize abstract learning content and phenomena to increase understandingof subject areas.- vibeke.klovstad vibeke.klovstad Sep 23, 2013

(4) Do you have or know of a project working in this area?

  • Last semester, in may 2013, i did an ITEC pilot with digital reconstructiion of holy bulidings in Sketchup and Minecraft, and the buildings the student created is beeing printed now. I am not avare that any other has done something with 3D printing in secondary schools in Norway. - stefan.reppe stefan.reppe Sep 10, 2013
