The coming decade will likely change the economics of 3D
printing and additive manufacturing (AM). Ric Fulop, CEO and co-founder of
Desktop Metal offers a number of predictions for the future of 3D printing and
additive manufacturing in the 2020s. For one, he believes 3D printing is
sufficiently mature for production. Over the next 10 years, mass production using
AM may become a reality and not just a promise. The general belief has been
that AM was too expensive to compete with traditional manufacturing methods.
Fulop believes those days are over. For
example if we look custom

then under mens clothing
section we can see advanced
clothing manufacturing makes easy to fulfillments in short time. Moreover newly mens t shirt

best part in fashion industry.
What’s changed? Fulop points to the cost of 3D printing
technology coming down in price, 3D materials becoming less expensive and more
varied, and improvements in 3D printing equipment. We caught up with Fulop and
asked him about his predictions for 3D printing and additive manufacturing over
the coming decade.
AM’s New Frontier
Design News: Explain your prediction that the next frontier
for additive will be in functional end-use applications and mass production
Ric Fulop: There is a long arc in the evolution of the
additive manufacturing industry and I’m excited that we are able to do things
now that people haven’t been able to do before. The 3D printing industry has
been around for more than 20 years and it’s come into the prototyping and jigs
and fixtures space with strong penetration. But, we haven’t even scratched the
surface.
I’m particularly excited about the next frontier of additive
manufacturing. Over the next year and into the coming decade, I’m expecting to
see growth from this sub-segment of jigs and fixtures and early use cases to
mass production, spare parts and functional end-use applications for components
that were traditionally made with other manufacturing techniques. The industry
is now mature enough that we can design machines that actually leverage these
technologies into the products that people use every day.
AM Competing With Traditional Mass Production
DN: How will advances in 3D printing help AM compete with
traditional manufacturing?
Fulop: Manufacturing is value at scale. You’ve seen the
first wave of 3D printing technology adoption primarily in the design
validation, prototyping, jigs and fixtures, making the factory more productive
and some tooling applications. And if you look at the total manufacturing spend
today, less than 5% is in prototyping, product development, or in tooling, and
so that’s where AM has played to-date.
In this next decade for 3D printing, we are entering an
exponential curve because the technology is more affordable, there are more use
cases and more supply of raw materials, and that opens up the application
space. This enables this new market, which is going from that early component
now to end-use parts and spare parts. Now, 95-99% of the 3D printing spend will
go into making the parts you want to make.
Scientifically artwork niches impacted seriously over

Changing Product Design
DN: Is AM changing the nature of product design?
Fulop: Absolutely. One of the things that’s unique about
additive manufacturing is that it frees you from the tyranny of tooling.
Tooling has been great because it lowers your per piece part cost, but it gives
you a big upfront cost and limits what your product can do in terms of freedom
of design. The great thing about AM is that we are now starting to do design
that is physics- or math-driven.
Now you can actually achieve the shape that you wanted,
lightweight it to get the performance you need, and, with the latest design
tools like generative design, you can really do incredible things. When people
look back on the 4th Industrial Revolution 50 years from now, they are going to
be talking less about the Internet of Things (IoT) and more about how we
removed 30-50% of material that we had in automobiles and how everything has
become more efficient.
