With ever-advancing technologies and artificial intelligence creeping into the workforce, job security for current and future generations has never been more worrying. Economic instabilities have shown just how quickly some industries can boom and others perish. So how is British Columbia’s job market going to evolve and what do we do to help workers get the best possible employment opportunities in the future?Story continues belowThe future is here. A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the structure, mechanical properties, look and feel of real organs. How close are we to being able to print the organs we need?Michael McAlpine, an associate professor of mechanical engineering at the University of Minnesota, joined CKNW’s Lynda Steele on Monday to discuss the Human X project.He says the cutting edge work they’re doing could allow health care workers to repair, restore and regenerate ailments in humans, but also potentially give the average person augmented capabilities above what biology normally provides.LISTEN: The future of 3D printing in medicine

My students are from a very multi-cultural neighborhood in Northeast Philadelphia. We are representing students from over 40 countries, many religions and even more languages. Our school is overcrowded, and we have an addition being built to house everyone. Many of my students come from places where they had no access to technology, good schools, or even religious freedom.
My students deserve the best education that we can give them!
So many of them come to us with no educational background from their countries of origin. We have an active ESOL population who are trying to learn English and assimilate into our culture. We have female students who didn’t have access to schools in their past. My kids need a lot of support!
We are requesting a 3D printer and the filament that goes with it to make a difference in my students’ lives. Most of my students come from places where due to poverty, war and other issues, they have not been exposed to technology. Showing them how technology can be used not only in a classroom, but in real world applications can help them to make decisions about exciting careers in the technology field as they make decisions about what high schools to go to and what careers they want to have in the future. I want to be able to teach kids about sophisticated concepts such as tolerance and coaxial movement with examples that not only stick with them, but that they create for themselves and can hold and explain. We live in an instant gratification society. Eventually, I want my students to create a 3D tolerance piece that uses and incorporates their technology skills with meaningful,thought-provoking art. I want my students to take the time to design something and then create it in a format they can hold and use. One easy and fun project that I would like to start with is for each of them to design and print a 3D keychain of their first names. It would be concrete and meaningful to them. We will then work on more advanced projects. We plan to use the printer in classes during the day, and perhaps an after school club.
3D printing can tie in technology, science, math and the arts.
It can incorporate every other subject that the students use in school, and can put them on the road to success in the future. Technology is the future and my students must be prepared.

The Maryland-based Naval Air Systems Command (NAVAIR) recognizes the many benefits that 3D printing can offer our nation’s fighting forces, and has been working to educate its workforce on the technology, most recently with 3D printing courses by the Naval Air Warfare Center Aircraft Division (NAWCAD). Three years ago, the organization, which provides the US Navy with life-cycle support for the naval aviation aircraft, systems, and weapons operated by the country’s Marines and Sailors, made its intentions for additive manufacturing clear.
In 2015, NAVAIR announced at the Sea-Air-Space exposition that it planned to introduce a 3D printed flight-critical metal component in a flight-ready aircraft within three years. A little over a year later, that component – a 3D printed titanium link and fitting assembly – was successfully tested for the first time on an MV-22B Osprey military aircraft at the Naval Air Station (NAS) Patuxent River. According to Inside Defense, after that successful test flight, the implementation plan called for the part to be certified to the full performance life of the original.
Now, NAVAIR is estimating that by the end of this year, it will have approved almost 1,000 3D printed parts for use across the fleet. According to a NAVAIR logistics officer, that number is nearly a tenfold increase from what’s currently available.
NAVAIR’s assistant commander for logistics and industrial operations, Brig. Gen. Greg Masiello, said at this year’s Sea-Air-Space conference, which ended yesterday, that the command has 135 parts right now that the fleet is authorized to 3D print and put into use.
Masiello explained that by the end of “2018, we’ll probably be in the neighborhood of a thousand parts . . . some of those will be metal.”
According to Masiello, those 1,000 parts will vary from small helmet modifications to major flight-critical aircraft parts. He also explained that NAVAIR has set up a sort of triage system, which uses color categories to classify different parts depending on their airworthiness. For example, parts which don’t need airworthiness are classified in such a way that a request to 3D print them is able to be processed much more quickly.

“All that aside, there’s preconditions: you have to have the right material to go in [the printer], you have to have the right process, and then you have to have the right printer. And for some of those complex metal parts or even the cast parts, that’s not a standard printer,” said Masiello.

However, when asked how NAVAIR will manage to process and authorize flight critical parts at a faster rate of speed, Masiello said that it’s easier to print some parts than others, and that it’s not the mission of the Navy to get every flight-critical part operational. He explained that the parts aren’t “necessarily, economically or even technically optimized for that.”
Over the last few years, 3D printing has continued to be integrated into the Navy’s supply strategy. Two years ago, it was predicted that Navy fleets would soon be impacted by on-demand 3D printing, and it’s clear that they’re still working toward that goal.
More and more now, we’re seeing the Navy and Marine Corps work to increase the adoption of additive manufacturing, whether it’s by 3D printing munitions, drones, barracks, and other components or working to decrease the logistical footprint and increase sustainability.
But, according to NAVAIR’s additive manufacturing team lead Elizabeth McMichael, who also spoke at the Sea-Air-Space conference this week, there’s still a long way to go in terms of 3D printing flight-critical parts.
“I think what’s standing in our way is standards,” McMichael explained. “It’s having enough data and understanding on our side to be able to put a standard in place to say . . . here [are] the elements you have to consider.”
McMichael stated that those standards are currently being created. But, an additional challenge comes in having the data that’s associated with the standards.
McMichael said, “If an industry partner makes a part, we need to be able to tell them what data we need to see.”

The Commonwealth Scientific and Industrial Research Organisation’s (CSIRO) Data61 is on the hunt for a 3D printer to assist with research and support its growing robotics capability.
According to the request for tender (RFT) published overnight, Data61 is seeking the high-end, multi-material 3D printer to assist with research and to support the organisation with soft robotics emerging capabilities, as well as aid the development of complex robotic systems.
The printer will support Data61 with the development of sensors for integration into marine wildlife, and in printing multi-material granular materials, as some examples.
The printer is required to print non-standard materials, such as heat-resistant polymer skins and sensorised/composite soft body materials, the RFT explains.
Specifically, Data61 has asked the printer be capable of handling a significant volume of work, creating production-quality parts, printing a variety of hard and soft materials, as well as be integrated into existing 3D printing-related initiatives in use by the Robotics and Autonomous Systems group (RASG) within Data61.
The RASG focuses on building and deploying robotic systems that perform in environments labelled as challenging, such as outdoors, in remote regions, or in difficult terrains.
“RASG has identified this printer as a key piece of infrastructure for continuing to develop our robotics capability,” the tender explains. “The range of parts that could be created on such a printer would bestow our robots with enhanced abilities beyond those currently attainable, and allow us to use our robots in more challenging scenarios. It will be a crucial tool for our engineering team as they continue to push the state of the art in applying 3D printing for custom, high-performance robots.”
The tender closes April 23, and it is expected the contract will begin by April 30, 2018.
