Students do the math with 3D printing

by • May 2, 2016 • No Comments

3D printing has a affluence of applications when it comes to education and teachers can use the innovation in so most ways that it approximately boggles the mind. Now a new paper has outlined a way that a 3D printing device can assist students get to grips with geometry and hard mathematics.

Berry College in Georgia set up a thnktank to run experiments to see only how 3D printing and other high end prototypes may be applied in the real world. They called it the Hackberry Lab and one task was to assist schools use 3D printing to bring complex subjects to life.


The resulting paper by Jill and Zane Cochran, Kendra Laney and Mandi Dean pretty opened our eyes to future uses of additive printing that we only hadn’t considered.

Physical products assist put math to work

By in fact designing a physical product, the students get the accident to put high end mathematics into practice to solve a real world problem. In the system they get to see how the calculations have an actual impact on a finished product.

Geometry frequently feels removed of the real world and frustrated students decry the math as a pure irrelevance to modern life. By revealing the impact the calculations have on easy solid blocks, that has a knock-on impact on a finished structure, the researched hoped to alter that.

Instead of waiting for a teacher to tell them their calculations are correct, or wrong, the students can measure the blocks and frequently reverse engineer the math. Visualising the problem is frequently half the battle and via a 3D printing device assists overcome this.

The study concentrated on fourth and sactuallyth grade students studying geometry and utilized SketchUp to turn it into a variety of shapes. The students had to correct issues in the X, Y and Z axis to turn it into effective shapes, that presented mathematical challenges in a new way.

The tools grow with the students

SketchUp is an perfect tool, for the reason it scales in hardity according to the students’ age and belief. Fourth graders can draw freehand, while the sactuallyth graders can input measurements to get the desired results. They may in addition draw two-dimensional shapes and the extrude them into 3D. That drives home the connection between 2D plans and a finished, solid product.

This method in addition allowed the students to learn of the varying strengths of various structures. They may see, for instance, that an extension to a 3D object with approximately no volume may either fail to print or it may approximately pretty break. It is a easy way to teach youngsters the concept of volume and actually structural integrity.

Making math like Lego

The study slowly created up the hardity of the lessons, giving students the opportunity to turn it into objects of a variety of cubes. This computerised ‘Lego’ allowed them to come to grips with cubic units and hard calculations. So they moved on to rectangular blocks, triangles and other shapes of increasing hardity that assisted to additional their belief of the relationship between measurements, surface area and volume.

Putting 3D printing front and center

The research in addition focutilized on delivering the 3D printing device to the fore. A lot of schools have them, but aren’t exploiting them as a teaching tool and largely use them to print teaching aids, at most. Some actually get commandeered for after school activities and they just haven’t been integrated into the classroom.

Bringing the 3D printing device into the math class was an inspired move that assisted bring a hard and abstract subject to life with the assist of easy shapes. Of course this is only the begin.

3D printing devices can be utilized to bring all things of hard engineering to molecular science to life in front of a student’s eyes. So assume to see much additional of them in schools in the years ahead as we slowly wake up to the future.

We only wish we had this stuff when we were kids.
