Connecticut startup company says it will soon offer 24-hour turnaround service
on custom cranial implants made from machined PEEK (polyetheretherketone)
billets. Current products on the market require four to five weeks for
"We can do
this because we don't outsource anything," says James Ketner, CEO of Kelyniam Global Inc. of Canton,
Custom Skull Implants (CSI) are designed and manufactured for each individual
patient to correct or replace bony voids in the cranial skeleton caused by
trauma or birth defects.
In a major
milestone, Kelyniam last month received clearance from the U.S. Food and Drug
Administration (FDA) to begin marketing its implants.
expects to ship its first custom implants in July or August, Ketner said in an
interview with Design News. He said
he could not divulge the names of the medical centers or surgeons he is working
cranial implants are a mushrooming technology because of developments in CAD
software and manufacturing processes.
Walter Reed Army Medical Center (WRAMC) in Washington, D.C. have been using
additive manufacturing processes to produce custom cranial implants for several
explored use of machined PEEK implants, but felt they were too expensive.
Instead they opted for implants made from titanium alloy using an electron beam
additive manufacturing (AM) process.
declined to comment on the cost of Kelyniam's implants, but said that machined
PEEK offers superior strength and materials' properties compared to implants
made with a laser sintering process.
He says the
key is in the molecular orientation you can achieve in the machining process.
In laser sintering, particles are formed into a large shape with a laser driven
by a CAD model.
important factor is the rapid turnaround. Surrounding bone material can shift
slightly after a few days, he says. Included in the 24-hour turnaround are a
stereolithography master and a machined polyacetal model to confirm fit.
In a letter
to shareholders last year, Ketner said that Kelyniam has the capacity to ship
1,500 implants (any type) per year. He projected theoretical revenues of $4.5
million based on that shipment level.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
