NanoSteel Launches 3D Printable Tool Steel

New Case-Hardening Steel Designed for Laser Powder Bed Fusion

Printed Industrial Die Demonstrates Performance of the BLDRmetal™
L-40 Powder

PROVIDENCE, R.I.–(BUSINESS WIRE)–NanoSteel®,
the leader in nanostructured steel materials, today announced the launch
of its first product for the laser powder bed fusion additive
manufacturing process. BLDRmetal™ L-40 is a case-hardening steel powder
that provides high hardness and ductility (case hardness >70HRC, 10%+
core elongation) and prints easily on standard commercial equipment.
This alloy provides superior performance to M300 maraging steel and is
an alternative to difficult-to-print tool steels such as H13. Expanding
the potential use of 3D printing in a wide variety of hard materials
markets, BLDRmetal™ L-40 is designed to be used for parts including
tools, dies, bearings and gears.


The capabilities of BLDRmetal™
L-40
were demonstrated by printing an 8-inch roll thread die set,
which outperformed dies machined from D2 and M2 tool steels. “We tried
nearly every combination of material and conventional CNC machining
process to create our dual-thread die sets, none of which could cut or
grind the complicated dual-thread geometry,” said Mark Doll, President
and CEO of Perfect Lock Bolt America Inc., the only manufacturer of
dual-thread fasteners in North America that are resistant to
self-loosening. “The NanoSteel solution delivers exactly what we are
looking for, including excellent surface finish, flexibility, as well as
strength and hardness for maximum die life. This is a welcomed
technological innovation to the fastener industry. We have been pleased
with our testing and are slated to start production this year.”

NanoSteel developed this high hardness alloy through rapid iterative
development at CFK GmbH, an industry-leading 3D printing service
provider, whose expertise was instrumental in developing the die from
concept to finished part. “For us, the most important attributes of
NanoSteel’s BLDRmetal™ L-40 are that it is easily implemented and
creates crack-free high hardness components, which sets it apart from
the many other tool steels we have tested” said Dr-Ing. Christoph Over,
CEO at CFK. “We are proud to be a preferred printing service provider
for NanoSteel, which will allow us to continue to offer the most
valuable products to our customers.”

“Launching BLDRmetal™ L-40 after successfully producing the roll thread
dies ensures the commercial viability of the new alloy for customers
investigating the use of additive manufacturing,” said Harald Lemke,
Vice President and General Manager of NanoSteel Engineered Powders. “We
don’t stop at material design, but create joint solutions with our
customers, facilitating the process from material selection and
prototyping to fully qualified production parts.” Building off earlier
products for binder jet printing, NanoSteel continues to expand its
product family for additive manufacturing.
