The 3D Printing Revolution

696 notes

This course will demonstrate how 3D printers work, show what people make with them, and examine the 3D printing ecosystem. It will also explore the future of 3D printing and discuss how this technology will revolutionize our world. The course materials include informative video lectures, on-location interviews with a variety of 3D printing experts, and engaging hands-on exercises. Learners who complete this introductory course will have a solid understanding of 3D printing and its revolutionary potential, and will be able to print and customize 3D designs. This course was listed in the top 50 MOOC's of all time by Class-Central (https://www.class-central.com/report/top-moocs/)

Now, let's take a look at applications.

How 3D printers are being used.

The next course in our specialization will delve in more detail on this topic.

So just wanted to give you a few examples here.

At present, 3D printers are being used by many firms, not only for

prototyping objects, but also for manufacturing them.

For example, General Electric uses 3D printing to make thousands of parts for

its jet engines.

Also, Nike is working on making 3D printed shoes.

And Loco Motors, a car company, recently 3D printed an actual car.

In the US, most hearing aids and dental implants are 3D printed.

And several universities and

firms are working on technologies that may some day produced 3D printed human organs.

For example, the University of Louisville recently

announced that they hope to 3D print a human heart by 2023.

We'll discuss this and several other 3D printing applications,

in the second week of our course.

Although, most desktop 3D printers will never make a car or a human heart,

there are still lots of amazing things that could be made using low cost,

desktop 3D printing technology.

Provide some stories of what our students who come to our lab

are using this technology to make everyday.

We'll discuss this in the second week of our course.

If you complete the specialization, you will be able to design and

create things that you probably haven't even begun to imagine yet.

That help guide you into how to think about the things that you can make using

a 3D printer, please take a look at this 3D typology which I developed a couple

years ago with one of our doctoral students as a way of thinking about,

what these tools can make.

So my doctoral student and I examined 500 different objects that

had been posted on the website, thingiverse.com.

And we tried to classify these objects using a typology.

So what you see here is the typology.

It has two axis resulting in four categories.

The first axis, the horizontal axis, is the type

of product whether it's a new product or an existing product.

The second axis, the vertical axis, is the degree

to which the product is a standalone object that just works by itself.

Or a component or a piece of a larger object.

So we combine these two axis we have these four archetypes.

So going from the top left, we have creations and

what you see here is a grading dice.

And this is a dice that has different grades, A, B,

C and D and also a couple others.

And this is an example of a new object that you

wouldn't be able to buy in a store.

And it works by itself, you just toss a dice so it's standalone.

Moving to the right, we have the next category which are substitutes and

they are simply objects that you could buy in a store.

Instead of buying in a store, you would print it on your desktop, for example.

So here we're showing a whistle.

So for example, although you could buy a whistle in the store, if you were coaching

your son's soccer game and it was 6 AM and the store was closed and

you needed a whistle, printing it would be a convenient way to obtain it.

The next category down to the right is something we call replacements.

And what you see here on the right is this knob on the right was 3D printed for

an old stove.

And so, lots of things that we have something breaks and

it's hard to find a replacement object.

And now if you have a digital design or

if you want to sketch the object in a 3D modeling program such as SketchUp,

or perhaps even scan the broken piece, you can now print a replacement object.

And the final category on the bottom left is something that we call solutions.

And what you see here is a solution to a problem

of trying to integrate two different toy systems.

So this is called a duplo brio connector and

the bottom it connects with Lego duplo blocks.

And on the top across the top is the brio train track.

So this connector allows you to integrate this two different but

in compatible toy systems, so those are solutions.

So we develop this classification and then we randomly picked 500 different objects

on Thingiverse, and then independently my student and I each try to classify

these 500 objects into 1 of these 4 different boxes.

So what do you think we found?

Which category had the most objects?

Well, let's take a look at that.

So as you see here in this next slide that by far and away the biggest category,

over half of these objects, work creations, and

you see the percentages for the other three categories?

And this is interesting because we have to think of 3D printer

as creating existing products, and some individuals will say,

why would I want to make my own whistle when I can buy within the store,

well perhaps you couldn't if the store was an open?

But that's really missing the point, the key point here is that 3D printing

allows us to create new objects that have never been seen before.

So the fact that the majority of these objects,

51% are creations is really interesting.

This suggests that people are using 3D printers

to create new-to-the-world products that have never existed before, and

this is really the magic of 3D printing.

I hope this typology has been useful in helping you think about

the sort of things you can make with a 3D printer.

As you can see, 3D printers can make a variety of objects, both those that have

already existed as well as those that have never ever been made before.

The possibilities are endless and

the use of this technology is as broad as your imagination.

I hope this overview of 3D printing has provided you with a better understanding

of how you can put your imagination into action, and turn your ideas into objects.
