CalRAM Inc.

working with CalRAM to optimize
a system. Reducing the weight of anything that flies carries with it substantial
benefits for customers ranging from increased payload, lower launch costs and
improved fuel efficiency," adds Treacy.
CalRAM also can reproduce customers' obsolete spare parts by scanning
them, converting the 3-D scanned image
to a CAD file and printing them. "The
benefits of additive technology in the
production of spare parts for defense
and commercial aircraft is immense
given the long service life, high cost and
lead-time of spare parts," says Treacy.

Looking Ahead
Because PBF is still a relatively new
manufacturing method, CalRAM faces
the challenge of ensuring its staff is up-

86

to-date with the technology. "Because
we're on the cutting-edge, one problem
we run into as an industry is finding a
workforce with the skillset needed to do
this work," Collins says.
To create a pipeline of skilled professionals, CalRAM is involved with
America Makes, a national organization
dedicated to advancing additive manufacturing and 3-D printing efforts.
CalRAM, in collaboration with others
participating in America Makes, Robert
Byrd College in northern Virginia, is developing a national curriculum that can
be used to train technicians in the use of
the method.
"We are helping create the next generation of engineers and technicians in
additive manufacturing in the United
States," Collins adds.

Pekar predicts big things for additive manufacturing, particularly when
it comes to large, complex parts. "This
will soon be a billion-dollar industry," he
says, noting that the method is already
gaining traction in satellite production.
"In the coming years, we will see a transformation in the aerospace industry as
metallic additive parts are qualified on
higher volume aircraft." mt
SLM Solutions NA, Inc. offers additive manufactur-

ing systems for fast and cost-efficient metal part production. To meet an increased demand for complex aluminum
parts, CalRAM employs the Selective Laser MeltingĀ® System: SLMĀ®280HL. By applying the option for twin (400W)
lasers, the SLM 280HL's bi-directional powder recoating
and closed-loop powder handling achieve the increased
build speed and safety necessary to support production
runs associated to CalRAM's growth. Additionally, the SLM
280HL provides a 280 x 280 x 350 mm build envelope and
open software architecture that offers the freedom of
controlling system parameters to optimize and meet strict
production needs.
