[MUSIC] Hi, I'm here in Youngstown, Ohio at the National Additive | |
Manufacturing Innovation Institute, also known as America Makes, | |
which is a lot easier to say. America Makes is a really | |
interesting operation. It began in 2012, started by the Obama | |
Administration as way to reinvigorate American manufacturing using 3D printing | |
and atom manufacturing technology. Now America used to be a country | |
that made lots of things. I grew up in a factory town. My grandfather made ball bearings for | |
45 years. My grandmother worked in | |
a clothespin factory. But over the past 15, 20, 25 years, | |
you see increasingly less and less made by American companies. So America Makes is designed to | |
reinvigorate this manufacturing ethos. It's a unique public and private | |
partnership, again, founded by the U.S. Government. But you'll see filmed | |
machines donated by large and small 3D printing companies, such as | |
MakerBot, Stratysys, and 3D Systems. I'm here today to talk to | |
you about Mark Cotteleer. Mark is a consultant for Deloitte. In fact, he's their specialist on | |
3D printing item manufacturing. He's going to talk about | |
the difference between the two and how what you're learning here in this | |
course, about desktop 3D printing, can be applied to much broader manufacturing | |
techniques at a factory scale. Let's go find Mark, and | |
learn about additive manufacturing. Come on. Well Mark, thank you for | |
taking the time to be with us today. >> It's good to be here Eric. >> Can you start off by telling us | |
a bit about your 3D printing story? How you became interested | |
in this technology? >> So I've been involved in 3D printing or | |
additive manufacturing, you'll hear me call it | |
additive manufacturing, at an industrial scale for | |
about three years now. And Deloitte is one of the largest | |
professional services firms in the world. We have a very advanced technology | |
practice where we help our clients understand how to take both manufacturing | |
and information technologies and deploy them in pursuit of | |
value inside their businesses. And when we looked around and said what | |
are the critical technologies that we're going to need to be able to help | |
our clients understand for the future. Additive manufacturing, | |
3D printing was clearly one of them. Additive manufacturing | |
is not a new technology. The original process, stereolithography, | |
was invented over 30 years ago. The technology used to be | |
referred to as rapid prototyping. What we're seeing now | |
is a bit of a breakout. The technologies have advanced to | |
a point where the economics and the quality is sufficient to actually | |
move into final part production. We have done quite a bit | |
of work in aerospace and defense and in military applications. Trying to understand how additive | |
manufacturing can be used to either enhance sustainment, | |
that is the ability of planes to fly, of equipment to run very rapidly. We're looking at supply | |
chain applications, so how do we manage what we call | |
long tail inventory applications? So maybe I have parts that | |
I have to serve clients for products that might be decades old. And if someone orders that part, | |
maybe the toolings not available, maybe the supplier's gone out of business, | |
maybe I don't even have a design for it, and I need a way to manufacture it. So we're working with clients to | |
understand how can I rapidly produce parts in a lot size of one in order | |
to service that customer. We're working with clients to help them | |
conceptualize how they can create entirely new products. By using the design capabilities | |
that are enabled by additive manufacturing to either simplify | |
the number of components that go in. So I can produce all as one piece instead | |
of having to assemble multiple individual subcomponents. Or maybe I can redesign to take | |
weight out using lattices, or taking nonessential material out of | |
different parts of the component in order to reduce weight, or increase performance. Or we're seeing applications where we're | |
enabling entirely new business models. Lots of really new exciting application | |
areas for this particular technology. We're just getting started. Deloitte has its history in | |
things like auditing and tax. But we are in fact one of the largest | |
consulting firms in the world, and one of the most respected. We have leading practices in analytics, | |
in supply chain and manufacturing operations, in lots of | |
different areas, it might surprise you. So people should check | |
out what all we're doing. We are interested in this space, both from | |
the perspective of the technology itself, so how is it that we | |
deploy these machines? But it's also important to | |
recognize that these machines exist within what we refer to | |
as the digital thread. That is, | |
in order to allow this machine to work, we need an entire technology | |
infrastructure built around it. We'll help a company design its | |
additive manufacturing strategy. We'll help a company figure out | |
what components are appropriate for being manufactured using | |
additive manufacturing. We'll help them choose the equipment. We'll help them identify other | |
partners they want to work with, what is the software, how does that | |
digital thread all go together. And we'll help them secure it | |
by using our cyber security services to actually make sure | |
that nobody can hack into it. Which, if you think about it, | |
can be a pretty big deal. And then we'll also help with | |
the workforce transformation. So we have a big human capital practice that does all the change management | |
around helping people understand how the change of this technology | |
is going to impact their business. When we talk about the digital revolution, we have to extend even beyond | |
additive manufacturing into, you could call it industry 4.0, | |
you could call it smart manufacturing. You could call it the future | |
of manufacturing. It goes back to this notion of the digital | |
thread and to what we like to talk about as the physical to digital | |
to physical transition. So we all live in a physical world, | |
we interact with physical objects. But so much of the enablement of | |
that world has become digital. That is, we use information technology in | |
order to make ourselves more effective, more efficient, | |
in order to improve our quality of life. And so, as manufacturers, | |
as service providers, companies need to understand how to draw | |
off information from the physical world. That could be about the state of | |
the products that they produce. It could be about the demands that | |
customers have for those products. And that maybe the individual | |
customizations that they are looking for to make it personable to them, | |
as individuals. The manufacturers need to be able to draw | |
off all that information using sensors or other technologies. They need to be able to apply advanced | |
analytics and other computing systems in order to make better decisions about | |
what and where they want to produce. And then they need to actually | |
transition back into the physical world. This is where additive manufacturing comes | |
in, to produce the products that have the fit and form and performance that | |
are required by customers today. And so all of these information and | |
operations technologies have to work together in this overarching | |
digital thread in order for a company to be successful | |
in the 21st century. With additive manufacturing, | |
that may include the ability to, eventually at least, mix materials, embed | |
sensors so that we continue that virtuous cycle of going from the physical | |
world to the digital world. To the physical world, to the digital | |
world, to the physical world, to the digital world, on and on, always | |
improving and serving our customer better. The difference very often is one | |
of scale and precision when you look at the difference between say | |
a desktop and industrial scale. So we have some of the models that you | |
produce, and you've been working with this airplane model that you're | |
producing using a desktop printer. That is a fused filament process | |
that we often refer to as FDM, fused deposition modeling. This is a similar object made through | |
a fused filament process as well, they look very similar. And the main distinction that you're | |
going to find here between the desktop and the industrial scale is one of size. You can produce a much bigger part and | |
one of precision. So you're going to see a much finer | |
gradations depending on which of the machines you're using. Now these fused filament processes | |
are getting better and better everyday. We also have other technologies. So you've talked about SLS in your class, | |
selective laser sintering. That's another process of | |
additive manufacturing that is available at the industrial scale. This is the same object, same file, | |
we just sent it to a different machine, that is produced out of another polymer or | |
plastic material. In SLS, we're aiming a laser into a powder | |
bed, again manufacturing layer by layer. And what you'll notice here, the obvious difference in the color, | |
different materials. And so you've got different | |
material capabilities, different mechanical | |
characteristics between them. You'll also see some | |
differences in precision. So this process, you can get to | |
an even finer surface level. It's a powder-based system. That surface finish is determined by | |
literally the grain size of the powder. We've also got one here. This is a selective laser | |
melting process where we're actually producing | |
out of stainless steel. Again, it's a powder bed process. Again, we're going layer by layer. And so the big differences are between | |
what you are seeing on your desktop and what you are seeing in the industrial | |
application is really one of the size of the process. The precision of the process, the variety | |
of materials that you're able to use. Certainly the design principle. So, your students will perhaps be | |
learning to design objects using a fused filament process. The learning of those design principles, | |
of how to design for additive manufacturing, will be applicable | |
in a variety of different spaces. Now it's important to recognize | |
that different additive processes will yield different capabilities, and different opportunities to | |
expand the design envelope. So what they're really learning here is | |
that baseline, that foundation that's going to allow them to get a head | |
start on the rest of the world. They're also going to | |
learn to conceptualize the capabilities of | |
additive manufacturing. So that when they get to that company or | |
when they turn to their business and say hey, here's how additive manufacturing | |
can really play a role in our broader manufacturing context. They're going to be much better prepared | |
to have ideas about how to move that company forward using these technologies. The additive manufacturing space | |
compared to conventional manufacturing, is still relatively small. But the important thing is | |
that it's growing very fast. Additive manufacturing is not a panacea. It's not going to change everything. But it's going to change some things | |
in really, very important ways. Additive manufacturing technologies offer | |
the promise of addressing some really troubling, really challenging product | |
design and supply chain issues. The market is growing at | |
almost 30% per year and that's been sustained | |
over quite a long time. So we're looking at a market that is | |
growing by billions of dollars every year. There are academic studies | |
that show that there can in fact be a return on investment for | |
a home printer today. More likely than that, I think, | |
is we are going to see a dipole model emerge sometime | |
in the next five to ten years. Where your local big box retailer, | |
or maybe your local hardware store, will begin to deploy these | |
kinds of technologies. So when something goes wrong in your home, | |
or when you have a product | |
that you want to download. Perhaps you download and buy it, | |
purchase a design from a service. You will send that over to your local | |
shop and they will manufacture it for you, very much as America Makes did for | |
these objects for us today. And then sometime, | |
maybe not in the next five to ten years, we'll see that actually penetrate | |
the home in a significant way. At Deloitte we have produced | |
an online course, a MOOC. Go to www.dupress.com/3d-opportunity. We've got many perspectives that we'll | |
look at individual dimensions of the additive manufacturing questions. And then we also have our online course, which is very similar to | |
the course you're doing here. It's about three hours, | |
a certificate credit. That they can walk through each | |
of the seven ASTM processes for additive manufacturing. As well as a framework for understanding how additive | |
manufacturing applies to the business. It's won awards, we've had lots of users. And we'd invite everybody to participate. Additive manufacturing, the universe | |
of possibility is very broad and it's easy to get intimidated trying to | |
figure out, what am I going to do first? Just get started, particularly again | |
if you're a business that manufactures things, because your competitors | |
are getting started. And this is an area where you want to | |
learn and build capabilities over time. So, that you skill | |
yourself as an individual. And so that you deliver those | |
capabilities to your business, so that it can succeed in the long term. >> Don't be afraid to fail. >> Don't be afraid to fail. No. >> Well great job Marc, thank you so much. >> Thank you, | |
it was a pleasure being here. >> Thank you. [MUSIC] |
