REPORT: The future lies in joint replacements and … and maybe 3-D printing
BY NATE HENDLEY
Want to see what the future of medical manufacturing might look like? Check
out the Hip cup. Made of titanium, this new
product was designed and manufactured by
Precision ADM (PADM), a fledgling Winnipeg
firm primarily devoted to making medical
and aerospace parts.
The Hip cup is a hybrid part, according to
Derek VanDenDriessche, director of sales
and marketing at PADM.
The company used a Nakamura NTRX-
300 multiaxis machining centre to machine
the inner surface of the Hip cup to ensure
extreme smoothness. Much of the product,
however, was 3-D printed on an EOS M 290
metal additive manufacturing machine.
At present, part production at the company
is split roughly 50/50 between traditional
machining and additive manufacturing,
said VanDenDriessche. Other traditional
equipment used at PADM includes Matsuura
VX-1000 3-axis and MX-520 5-axis vertical
machining centres and a GFMS CUT 30 P
submerged wire EDM.
Precision ADM is a small, 12-employee
company that was incorporated in May 2015
as a for-profit spinoff of the not-for-profit
Orthopaedic Innovation Centre (OIC), also in
Among other activities, the OIC tests medical devices, including hip and knee replacements. The centre generated headlines a few
years ago by using 3-D printing technology
to create a kneecap replacement for a dog.
The Hip cup isn’t exactly a medical standard
yet. In fact, it hasn’t actually been implanted
in a human body (the company just received
its ISO 13485 additive manufacturing
certification for medical parts—the only
AM company in Canada with such status,
according to PADM).
The Hip cup was designed and made
in-house to show the company’s man-
ufacturing capabilities, explained
Traditional machine tools will still be
