Materials
While high-strength 3D-printed polymers
can match or exceed the mechanical
properties of certain metals, it's
essential to assess factors like temperature
resistance, chemical compatibility,
and long-term durability to ensure the
material can withstand the intended
operating conditions.
The design and manufacturing process
is another consideration. Designing
for AM may require a different
approach compared to traditional manufacturing
methods. Leveraging the
design freedom provided by 3D printing
can optimize part performance,
but it necessitates expertise in additive
manufacturing principles. Designing
for Additive Manufacturing (DFAM)
knowledge allows for even lighter and
more functional parts that can last longer
just like the traditional parts. Collaborating
with experienced partners
specializing in high-strength 3D-printed
polymers can mitigate these challenges.
Such partners should offer comprehensive
support, including material
selection guidance, design optimization,
and expertise in additive manufacturing
processes. They can ensure
a smooth transition and successfully
implement 3D-printed plastics as metal
alternatives.
A Path to the Future
As we look ahead, it's evident that the
aerospace and defense industries are at
the forefront of leveraging the potential
of additive manufacturing. They are the
main reason for the advent of high-performance
polymers in AM. The progress
in high-strength 3D-printed polymers,
advanced materials, and innovative processes
has paved the way for a promising
future. High-strength 3D-printed plastics
are emerging as robust alternatives
to traditional metals, offering performance,
reliability, and design freedom.
In this exciting transformation journey,
the aerospace and defense sectors
set a precedent for other industries.
From automotive to electronics, consumer
goods, and biomedical applications,
additive manufacturing offers a
unique opportunity to rapidly produce
parts on demand, reduce costs, minimize
waste, and streamline supply
chains. Well-informed and prepared,
Aerospace & Defense Technology, December 2023
the best organizations will print their
way to success in the digital age, seizing
the full potential of high-strength
3D-printed plastics in an ever-evolving
landscape of possibilities.
