the printing process to improve on
the CAD drawing. By using Eiger, engineers have the ability to organize the
fiber material in different geometries
to give the product extra stiffness or
alter its weight ratio. "The software
makes it easy to go from default settings to giving you as much control as
you want over the fiber that is being
laid down," Gumbert says.
The foundation of Markforged's
technology is its material. Printers use
a tough nylon filament that provides
flexibility while remaining impact-resistant, allowing for the strength manufacturers need for end-use components. All of Markforged's materials
meet those expectations for strength.
Onyx is a micro-carbon-reinforced nylon and the company's higher-end machines can also print using fiberglass,
carbon fiber and Kevlar.
Having innovative materials doesn't
mean much if the machine doesn't
work as advertised. Markforged

"things that will make
a big impact on businesses, we're going to
try to print it. we're
aiming to change manufacturing,
supply
chain and inventory
managing all for the
better." - Rebecca Dilthey
matches the ease of its printing process with quality that promises to limit downtime and avoid disruptions in
the production line. "A lot of our customers will buy our printer because
they bought another desktop printer
and it just did not work for them,"
Dilthey says. "We've brought the reliability and robustness of the high-end
printer down into the desktop world."
Reliability encompasses more than
just producing machines that stay in
service. Markforged machines must

also deliver on the company's promise to create 3-D printed parts that
meet or exceed the quality of traditional manufacturing methods. Unlike many competitors, Markforged
printers lack a heated chamber for
plastic printing. The heat can help
the printing process, but as parts cool
down the plastic may shrink and alter
dimensions. Markforged machines,
however, print at slightly above room
temperature, avoiding the warping issue found in competing equipment.
The new Mark X printer takes another
step forward in ensuring high quality
standards are met with in-process inspection capability. A laser displacement sensor on the machine's print
head can measure the accuracy of the
component to 1 micron. If the part is
off, the customer can stop the print
job and resolve the issue.
Measuring the accuracy in real
time gives better transparency into
the part, Gumbert says. High-end
