This is a cool topic!! But honestly, I don’t really understand it, because I have never really seen it. The following video by Armand Valdes gives a good explanation on what it is and how it has and can be used.
3-D printing in school is not a bad idea. Leapfrog 3D Printers are an affordable and useful tool for schools that can be incorporated into several subjects. I can see it being used in science, math, and even literacy. The authors of On a mission to help schools uncover the benefits of 3D printing for teaching state it can be used for:
- Capturing interest of students
- Stimulating interaction during class
- Creating tangible aids
- Hands on learning through 3D models
Linda Federico-O’Murchu (2014) has the same views with some drawbacks. She states that beyond the elementary classroom 3D printers are creating body parts, useful items, and even food. On the down side it is also being used to create weapons, and the international implications of copy right infringement are on the bubble.
However in the classroom, I see a use for the tool, and it might not be directly in the classroom but in the school. A 3D printer can ignite the imagination of students by creating the object they man not be able to hold and feel (Airwolf 3D, 2013). Engineering students can draw and use CAD designs to create something on a computer, but until a mold was designed, and the product was produced, the student could not see if it was a relevant idea or not. Now they can print it, work out the bugs, and create a prototype without a third party to wait on. High school students can now print samples of their work to include in an application to universities for engineering degrees. Science students can print 3D molecular models and fine art students can 3D print real life examples of their designs (2013).
3D models can teach students about production techniques and cost effective models for use in the real world.
On the elementary side, I can see this being more valuable in science and creation. If you have a maker space and you need a specific gear or part to make something work and it is not available, you can print it. For science projects, students can print the necessary items for a robot that may not be purchasable on the market yet. But in the long run, the printer could be used for thought provoking uses and spatial reasoning capabilities. There are students that do not understand the working of a small machine, how gears work in conjunction to size and shape, and a printer could be used to blow that model up so they can see the why of the operation.
In the report by Linda Frederico-O’Murchu she makes a lot of pros and cons for the use of 3D printers, but I feel the pros outweigh the cons by a landslide. No matter what the invention, there will always be a seedy side to it. Crooks and thieves will always try to manipulate the good for bad, and that is just the society we live in. The benefits of 3D printing are still in its infancy as far as I am concerned. The printers will no doubt be a thing of the future and not a fad. As prices fall and units become more affordable, the use in the classroom will grow. A student that can print the bones of an animal will no longer need to kill that animal for experiments. A student that can print a robot base for a rover will no longer have to find materials, and build something that may or may not work.
We know that 3D printers will never be able to create precious metals from plastic and that it will not replace all production in the world. However, in the classroom I think it might be the difference between knowing and understanding what something is and how it works.
