As you may know we are big fans of 3D printing. Whether it’s helping a horse, supporting sleep suffers or producing a personalised pen, we have a lot of time for a disruptive technology that might be the biggest tech innovation we’ve seen in decades. So we were pretty chuffed to spend some time with a 3D printing guru.
The guru in question is Chad Henry, a research scientist from our manufacturing team. Hailing from the United States, Chad brings a unique charisma and enthusiasm to our labs in Clayton, Victoria.
In order to find out a more about the man behind the printer, we put a few questions to Chad about his work and his life outside the lab.
What do you enjoy most about your job?
I enjoy that there is such a breadth of applications for metallic 3D printed components. Learning about the details of new potential uses, in order to best utilise the technology is interesting.
What does your job entail on a week to week basis?
Lots of interaction with companies interested in metallic 3D printing to explain the technical details and costs of it, all in order to search for successful applications for them. The other part is running projects, where we are always learning new things.
What would you say has been the highlight of your career so far?
Because I helped design and make it, when the JSF F-35 went full speed down the runway and took off for its first-flight, that was quite a career highlight. But you could argue that the successful landing was more important.
What is the biggest challenge you’re grappling with in your role at the moment?
Large OEMs (original equipment manufacturers) that manufacture metallic components and integrate them into systems that result in high value products are few and far between in Australia. It’s these kinds of companies that are putting money into metallic 3D printing over in the US and Europe. Plus, the Australian industry is risk averse. All of this is makes the uptake of expensive new technologies challenging.
If you were at a casual dinner party, how would you respond if someone asked what you do/research?
I deliver metallic 3D printing technologies to companies to ultimately help the country, as I am partially government funded. Sometimes that takes a little R&D to get things just right, so then we can develop and execute projects that have a positive return on investment for the company.
What are some common misconceptions about 3D printing?
It’s easy to do. It’s inexpensive and good business cases are abundant. Design optimisation doesn’t really matter.
What is the coolest thing you’ve ever printed in 3D?
Noting that cool is different from useful, I would say minimal surfaces (do an internet search if you need to – it is an interesting one) and mathematical based art.
What is the next big step for this technology? Good question. I’ll state two: 1) CAD software that makes taking advantage of the design freedoms inherent with 3D printing, and 2) driving down the cost. Both are important, already underway, and will continue to improve with time.
What was your first job?
Metallurgical Engineer at Bell Helicopter. This was in the late 90’s and we were 3D printing lost wax for investment castings then.
What profession other than your own would you like to attempt?
Sports Equipment Tester, analyser and designer. I am an OK athlete and I have an engineering mindset. I think I’d be good at it.
What hobbies do you have outside of your work?
I am a dad first and foremost. My kids are at a very fun age. I’d rather have dinner with them than anybody. The conversations are certainly candid and all over the place. Additionally, I try to find time for ice hockey, on- and off- road motorcycle track days, home brewing, table tennis, golf, and I have recently gone surfing a few times.
What advice would you give to somebody looking to follow your career path?
Have load-case and stress analysis capability and the knowledge to apply it to component design, along with the necessary CAD skills to then make it electronically.
What is the most funny/unique/odd situation you have experienced in your time at the CSIRO?
I have a 3D printed fish anchor (used to affix GPS devices) on my desk that was in a shark for some time before being removed. It has remnant organic tissue on it. Thank you CMAR (CSIRO Marine and Atmospheric Research). They learned a lot about sharks.
If you had infinite resources, what research/experiment/project would you like to work on?
Two things: 1) Getting real-time non-destructive evaluation capability into metallic 3D printers. There are multiple benefits that would result from this, and 2) Further developing large scale metallic 3D printing. Let’s just print the whole airframe.
Which song or band best captures your job and why?
I don’t know… let’s see… the vast majority of people seem to love 3D printing, but they don’t necessarily know the technical details or science behind it, so it just seems like magic. Maybe the magic is partly why they love it. Surely there are songs along that topic line. OK, I got it… how about, “You sexy thing (Do You Believe in Miracles?)” I mean, 3D printing is pretty sexy, right?
One final thought from our 3D guru – a piece of pub trivia, or a nice fact to unleash upon unsuspecting dinner guests
People should know that 3D printing isn’t an overnight sensation. It has been in development for well over two decades.
And finally, just because it is a little pet peeve of mine, I’ll share a quick piece of advice. First though, let me say that by itself, it won’t make you sound like you know what you are talking about, but it will certainly help you “not” sound like you “don’t” know what you are talking about. Got it? OK … here it is … Regarding 3D printing of metals, the process is fusion (i.e. melting).
He has founded six successful companies, holds 20 patents and began his career as an engineer with a PhD in physics. And, a month ago, he took the reins as Chief Executive of CSIRO. We sat down with Dr Larry Marshall to hear how he’s settling in.
You’ve been in the job for a month now. What are your first impressions of CSIRO?
Well, I know it’s only been a month, but I already feel like there’s so much research happening here that I’ll need another lifetime to discover it all.
It’s clear to me that people who work here want to make a difference. They really care about science and the opportunities it can offer to the community, the environment and to the economy. They’re supportive of each other and really want us to be the best we can be.
Is there any research you’ve heard about at CSIRO that particularly stands out to you?
I could inundate you with examples. Just off the top of my head, we recently helped someone walk again by 3D printing a titanium heel bone that his surgeon was able to implant.
We’ve developed a technology that helps remotely control longwall mining equipment so miners are safer and productivity is boosted by 10%.
We’ve used our maths and informatics skills to develop a tool to predict the number of people who will go to hospital emergency departments and by helping the hospitals better plan, we’ve saved them tens of millions of dollars and reduced the time people wait for a bed.
Right through to other examples like the work we’ve done to breed the perfect prawn that by 2020 will add more than $120 million to the value of the industry.
I could keep going, but I should probably stop there.
There’s been some conjecture around your views on water divining recently. Is there anything you’d like to say on that subject?
My grandfather was friends with a tribal elder who would walk our land trying to feel where the river had gone – he explained to me as a kid that the river was still there just hidden beneath the ground. He was very successful in figuring out where Granddad should drill. Drilling is very expensive so you need all the help you can get.
Now clearly, that wasn’t a scientific experiment and I was wrong to quote figures for success – I said it right the first time – “have you seen farmers find water?” – but later realised I shouldn’t have used the word “dowsing” which to me means find water, but apparently there are more narrow interpretations.
I was surprised by the reaction but also by the number of letters of support I received from people who clearly got what I was trying to say, which was: Entrepreneurship is about seeing a problem and imagining a solution, then inventing the technology to solve it. The inventor of the flip phone at Motorola was doubtless inspired by Star Trek.
A couple of years back, CSIRO’s Materials Science and Engineering team came up with a way to miniaturise atomic clocks and do what the Grace satellites do to detect water via gravitational anomalies. Entrepreneurship, like science, isn’t about playing it safe – if we aren’t failing we aren’t trying hard enough.
For me there is no such thing as failure, there is only learning – we can always do better (especially me with the media).
CSIRO has been through a lot of changes in the past year. Is that all over now?
That’s true. We are emerging from some rapid structural changes and I can’t promise that change is now over – that would be unrealistic in a world moving as fast as ours.
What I want to do is help our organisation focus on how we can contribute to the innovation, discovery and growth that Australia has come to expect from its premier research organisation.
So how do you do that?
We’ve got to focus our efforts and continually measure and demonstrate our impact. We’ve got to be more entrepreneurial and agile. We’ve got to get our overheads down and create value for our customers, and we’ve got to create some more headroom for exploration.
The first step is to get the framework right and that comes down to our strategy. That’s my big priority and something we’ll be locking down before June.
I have learned a lot about lean innovation and focussing on where we are unique. You’ll hear more about this, but let’s just say we’re learning from the lean innovation movement. Each and every person in our organisation will have a voice in this…
The genius and the power of CSIRO is distributed – it’s in our people, our partners and our community. We know a diversity of views is critical to innovation performance.
The more I learn about this place, the more conversations I have, the more amazing things I discover about CSIRO. I will be endeavouring this year to meet as many staff as possible, to hear about their work, and to learn from our customers and stakeholders about what we need to do to make CSIRO even stronger and more successful.
And do you think we’ll be starting our dragon research anytime soon?
I guess we’ll have to wait to see what comes out in the strategy. We should check in with Sophie about it.
Jesse Hawley: Hey Rob, is this okay? I have around 15 questions, when are you free till?
Rob Bell: I’m free until whenever really. I mean I have stuff to do, but no set times.
My favorite part of working on Scope, but working for CSIRO, is that I get the best of both worlds. I really like jumping into a different area of science each week, because the shows are all themed (sometimes very specifically, sometimes quite loosely). I have learnt an awful lot researching for the show, some of which I am sure I have now forgotten.
Number two. If you were at a casual dinner party, how would you respond if someone asked what you do? AND, what you do for research (whenever you get/got the chance)?
It’s funny I am never quite sure how to describe my job without sounding like I am blowing my own trumpet. I used to say that I was in Science Education, I think because people wouldn’t ask too much more about it, and that is what I did with CSIRO. But these days, now that at least a few more people seem to have heard of the show, I say I work on a kids science show. Overwhelmingly people think it is a great thing to be doing. If they don’t know the show they often assume we are on the ABC.
Cognitive failings aside, question 3: What does your job entail on a week to week basis?
Given that we pretty much make one half hour (well, 24 minute) show each week of the year, the weekly routine has to be pretty much constant. Monday and Tuesday are spent researching and writing all my bits (the stuff in between the stories that links it all together) for the episode we are due to film on Wednesday. Wednesday is filming. Thursdays I have off (kids etc.) and Friday we watch a completed episode (not the Wed. one) and make changes, fix ups etc. then begin to plan for the following week. In between that I help find stories, suggest ideas, themes, trips and read over other people’s story scripts to see how the science sounds. I am currently the only Scope team member with a science background.
It’s surprising to know there’s just one scientist on the team…
I think a career highlight in terms of Scope would have been winning the Japan Prize in 2008. Long time gone now I suppose, but it was an international award for educational television, and I was even flown to Japan for the ceremony and met the crown prince and princess. But I have been on many amazing trips with the show, digging dinosaur fossil in nth west qld last year was a great experience.
I didn’t know there was a crown prince and princess in Japan.
Which fossil deposit were you digging at?
We were about 45 minutes out Winton (2hrs from longreach), the dig was run by Qld Museum and the Age of Dinosaurs (set up after they discovered fossils out there a few years back).
They were working on getting out vertebrae and pelvis of a big sauropod. Very encased in rock, but the real work was back in the fossil lab, they have a backlog of many years there still to clean up and prep. Digging them up is the quick part it seems.
What is the most funny/unique/odd situation you have experienced in your time at SCOPE?
There have been a few of those. The show has always been a little quirky, and I have ended up in a few odd spots with my lab coat on. Perhaps the strangest was swimming with dolphins at SeaWorld (which was the good part), but then competing with them for the fish the trainers throw. Quite hard to catch a fish with our shaped mouths it turns out, but I got one once, and I took a while to get that taste out..
Were you in your lab coat too?
Next question: What was your first job?
My first paid job was picking strawberries. I grew up on a pineapple farm so had to help out a bit around the place, but they also grew strawberries in the district and during picking season would take all sorts and ages on. Tough on the knees that job. And I don’t like strawberries, but I think that was the case before picking them. I still like pineapple.
That’s a very Queenslandery first job
Aside from berry pickin’, what profession other than your own would you like to attempt?
I don’t really know what they entail, but I remember liking the idea of being a tech stock analyst at one point or working in an ad agency (even though I dislike most advertising, maybe it isn’t clever enough?).
What hobbies do you have outside of your work?
I play football (soccer) and have done most of my life. Getting older and slower of course, but I refuse to acknowledge that on the field. I ride my bike a bit, but not enough to own lycra, and I am pretty avid about brewing beer.
What advice would you give to somebody looking to follow your career path? Either a scientist, a TV person, or a science communicator (or all of the above).
That is a tough one. I lucked into what I do really. Even getting my job with CSIRO Education without any real Education or communication study or background was probably a bit fortunate. From there, I was in the right place at the right time, as Totally Wild used to come and film segments, and I was the new guy. Getting into TV presenting is hard I think, there seems to be not really a very defined path. But Science, follow the area that interests you the most, and if it is all of them, get into Science Communications (I didn’t know such a thing existed when I left Uni). We have had several ex-ANU Science Comms/Science Circus people work on Scope.
If you were at a dinner party, how much would science influence your conversation? This is an interview question. Not my own curiosity. (That too).
I guess it depend upon the topics, but invariably something comes up to which i can inject some level of “did you know”, or a gross fact or even just clarify (politely) someone’s misconception. Often the science comes in because people have been storing up questions to ask me though. I do wonder why they just don’t google, but hey, happy to try and help.
If you had infinite resources, is there a special topic or field that you’d like to base an episode on?
Penultimate question: Which song or band best captures your job and why?
They Might Be Giants. A band I grew up and listened to before my life in science. Now my kids like some of their songs too. But they are geeks who write the occasional science tune amongst all the others.
And finally – Did you have anything you wanted to add about working with CSIRO or Scope?
Oh, and what did you research before you got full-time into TV?
Nothing really to add. I really enjoy working for CSIRO. It is an organisation that so many Australians seem to respect, and they have always been so helpful and flexible with me off playing in TV land. Network Ten doesn’t always enjoy the same kudos.
Before TV, was CSIRO Education, and before that was my PhD and traveling the world for a year. But my PhD was in the area of ceramic fuel cells. So materials science was my thing I guess.
I love my job. As a CSIRO communication advisor I get to work with amazing scientists, hear fantastic stories of discovery and innovation, learn new things… and get paid to do it.
I began my CSIRO adventure in 2009 as a summer student working at the Parkes Radio Telescope. At the final seminar I asked ‘how do I get a job here?’ and four months later I was a communication advisor supporting agricultural scientists working across the country.
That physics degree didn’t help me understand the work they were doing, but then the job isn’t about becoming an expert in the science. Being a communicator is all about listening, asking those silly questions and helping the scientist tell their story. The only trouble is there aren’t enough hours in the day to tell them all.
I love my job, last week more than most, because last week I got to go on the new Investigator marine research vessel. I’ve never been to Tassie before so it was a week of firsts; first time visiting Hobart, first time on a research vessel and first time throwing my guts up on a piddling four metre swell.
Don’t ask me how I managed it but I scored a berth on one of Investigator’s sea trials. I have to admit my heart went badaboom when I first saw her sitting across the bay as I drove over the Tasman Bridge. Investigator is one fine lookin’ Sheila, even her aft-side looks good.
Once on board, the first thing I noticed was how quiet the ship is once you’re off the main deck. There was only a quiet hum from the engines and the occasional lapping of waves against the hull to disturb the peace.
I was lucky enough to score a cabin on the first platform deck (one below the main deck) with a porthole. It was bliss waking up to the reflection of the sun shimmering off the surface of the Derwent.
I’ve cruised before, but nothing is quite like the Investigator. I’m pretty sure it’s the biggest cabin I’ve ever had on a ship, although I had to make my bed. Oh, the horror.
You have to be really conscious of sound too; the crew works to 12 hour shifts which means your neighbour might be just getting to bed when you get up in the morning and you don’t want to disturb your neighbour. They might be responsible for steering the ship, or feeding you.
Yes, there are chefs on board, and what joy they bring to the voyage. Food is available 24 hours a day and I can personally vouch for how darn good it is. That’s a feat considering no one can pop in to the local supermarket.The ship’s pantries and cool rooms are substantial in size and sturdiness. Not only do they store enough food to feed up to 60 people (most of them burly men working long hours) for up to 60 days, they also have to keep the food stuff safe during rough seas.
While the food was delicious going down it was not so lovely coming back up. Turns out my guts of steel were not so steely. As we sailed over the continental shelf Investigator was tracking back and forth, mapping the sea floor. This meant changing the angle of the ship to the swell, from calm to rough and all that choppiness in between. Hello, lovely new bathroom.
I wasn’t much better the next day when the team were practicing deploying the big Southern Ocean Flux System (SOFS) mooring. These moorings have to survive the southern ocean for over a year at a time so they’re big and sturdy. The big float sits on the surface bobbing up and down with a long chain of instruments hanging beneath it. The four metre swell was perfect conditions to test deploying the mooring before the real thing in the southern ocean next year.
It was not so perfect (or mild) on my stomach. I’ve been in worse conditions and been fine but then in the past I’ve had the advantage of being on holiday; sitting on deck, eyeballing the horizon, drinking ginger tea. Investigator is not a holiday destination; it’s a research vessel and there’s work to be done .
The third day of the voyage dawned clear and calm (sigh). I ate a wonderful full breakfast to make up for what I had missed. Hat’s off to those who can do this for months at a time. Although, the views really aren’t so bad.
CSIRO has been darn good to me over the years. I thought it might be difficult to top starting off at the most beautiful radio telescope in the world, but CSIRO is just one of those places where no matter which way you turn, you can’t help but trip over an amazing story.
Meet Yogi Kanagasingam. Yogi works at our Australian e-Health Research Centre and his vision is to change the way eye care is delivered around the world to prevent needless blindness.
A ‘serial inventor’, Yogi has developed a number of low-cost diagnostic technologies that are used to take images of our eyes. These devices are helping in the early detection of serious conditions, ranging from those that directly threaten sight, through to stroke and Alzheimer’s Disease.
By focusing on affordable, mobile solutions, he is bringing quality eye care to thousands of patients who might otherwise have gone without.
Recognising this passion and dedication, Yogi has been named as a WA finalist in the 2015 Australian of the Year Awards. Here are just some of the sight-saving (and often life-saving) projects he’s working on:
Saving sight in remote communities
However due to the remoteness of some Australian communities, it can be very difficult for people to access this type of specialist care.
That’s why we’ve been working with our partners in Western Australia (Gold Fields and Great Southern) and Queensland (Torres Strait Islands) to set up remote eye screening – giving hundreds of people access to eye testing services.
This is possible thanks to technology Yogi has developed called Remote-I.
Using Remote-I, local clinicians are able to conduct routine retinal screenings, often as part of scheduled health clinic visits. The system then sends hi-res retinal images to a city-based specialist ophthalmologist via satellite broadband – allowing them to accurately diagnose and refer patients who need immediate treatment.
A global vision for eye care
Now Yogi and his team are taking Remote-I to the world. For the past year, they’ve been working with the Zhongshan Ophthalmic Centre in China’s Guangdong Province to introduce the technology throughout a network of ten hospitals.
With a population of over 100 million people in Guangdong, local health professionals are now using the technology to screen up to 1000 patients per week. That’s a lot of eye tests.
As well as giving patients access to specialist care, this project is also providing the research team with valuable data about blood vessel patterns in retinas. This will allow them to design algorithms that could be used to automatically detect particular eye diseases, aiding diagnosis in routine screenings.
Early detection of Alzheimer’s
Using curcumin (a compound in the spice turmeric), Yogi and his team have also developed a spice-infused eye test for Alzheimer’s disease.
Patients ingest the curcumin which binds to beta-amyloid plaques (the sticky proteins that indicate Alzheimer’s) showing up in retinal scans as bright spots which can be counted and measured.
Early results show the amount of plaque in the retina closely mirrors the amount in the brain. If confirmed, this could be the beginnings of an easy, non-invasive test for early detection of Alzheimer’s – maybe up to 20 years before cognitive symptoms appear.
We’re proud as punch of Yogi. As well as the groundbreaking work he is doing with us here at CSIRO, he is also giving back to the community in his personal time. Yogi is actively involved with local Rotary Clubs, including Freshwater Bay Rotary in WA where he helps promote regular eye screening for primary school children. This can make a big difference to students, as early detection of vision abnormalities can improve both academic and sports performances.
We wish Yogi all the best this Saturday when the WA Australian of the Year will be announced at Government House. WA’s winner will then join recipients from other States and Territories as finalists for the National Awards, to be announced on Australia Day 2015.

In Australia we generate 75% of our electricity from coal. This creates a lot of CO2 emissions, with increasing concerns about global warming and climate change.
Dr Paul Feron wants to be able to use the coal without releasing carbon dioxide. He leads a multi-disciplinary team developing cost-effective methods to capture and store CO2.
Paul’s team has built and operated capture pilot plants illustrating that the technology can be retrofitted to coal-fired power plants as well as smelters, kilns and steel works.
He is focused on reducing the cost of the capture process, so that the technology can be taken up widely – not just in Australia, but also in developing countries which depend on coal for their energy supply . So that we can meet the world’s need for energy without adding to CO2 emissions. Hear Paul talk about his work.
Next week the National Carbon Capture and Storage conference is happening at Cockle Bay in Sydney from August 31 to September 3 – visit the website for more information.

Dr Iain Collings decided early in his career that wireless communications was hot. Fascinated by the prospect of transferring information without wires or optic cables, he saw its huge potential to change our daily lives – and wanted to be a part of it.
The whole world is into cool electronic devices. Our growing appetite for smartphones, iPads, GoPros and FitBits has produced a huge new market – and wireless data transfer is essential for these devices.
What’s more, the more we use them, the faster our demand for higher rates of data transmission grows. Iain has focused his work on the use of multiple antennae to vastly improve the rate of transmission of data wirelessly. As he points out, this is fundamental to meeting the ever-growing global consumer demand. Watch this video to find out more.
