As 3D printing has become more and more mainstream, the traditional resource and skills barriers for manufacturing companies are evolving. This trend is changing the very face of education and manufacturing employment programs across the globe.
Today’s manufacturing economy has evolved into a customer-centered model that stresses speed of delivery, product value and a positive customer experience and 3D printing—with its capability to produce customized products quickly—perfectly addresses that model, but where many manufacturers struggle to meet these new market demands is in hiring and workforce planning. The availably of a well-qualified labor force to implement and oversee these new process dynamics is critical to the factory of the future.
SME and Skills USA, two organizations we’ve partnered with, are committed to developing, supporting and advocating for a new manufacturing workforce. To meet this challenge, Stratasys has partnered with SME to get additive manufacturing added to the coveted SkillsUSA national competition. SkillsUSA, Stratasys and SME are driven by similar missions – all are both dedicated to providing skills gap solutions and filling talent pipelines. Timothy Lawrence, executive director of SkillsUSA added “By partnering, we can truly make an impact on the manufacturing industry by engaging educators and students, to drive interest in career options and high-tech possibilities.”
The SkillsUSA Additive Manufacturing Contest, developed by Stratasys with the help of SME to support the growth of design centered experiences at both the secondary and post-secondary levels, kicked off this week with a uniquely additive manufacturing challenge that stresses the importance of both finding a solution and the approach the design and redesign process. Stratasys has been on the ground throughout the entire contest to provide engineering support in addition to the seven onsite printers. The importance of failing fast and moving forward once issues are identified will be a valuable and honed skill for future additive manufacturing professionals.
3D printing has opened the door to a new huge space of design and manufacturing possibilities and this space is only growing with the introduction of new printing materials, finer printing resolution, and the ability to print with multiple materials simultaneously. The combination of new geometric representations, new design paradigms, and new possibilities leads to challenges and opportunities for employers and the global workforce like never before.

A ground breaking investigative trial called 3D Hearts Enabling a Randomized Trial (3DHEART) recently began enrollment. This initiative is a clinical study to better understand the impact of 3D printed heart models for pre-operative planning for pediatric heart surgery We recently conducted an interview with Alistair Phillips, MD, who is the Co-Chair for the American College of Cardiology, Surgeons Section, around some of the impacts he has personally experienced using 3D printing in surgical settings, as well as his participation in the 3DHEART program.
Q: What has been your first-hand experience using 3D printed models for surgical planning? What information or advancement does using a 3D printed model offer over CT/MRI renderings on a computer screen?
A: I have utilized 3D-printed models for dozens of complex surgeries. We have pioneered a novel method for replacing a pulmonary valve that does not require open-heart surgery. While I was in Columbus, prior to 3D printing, we performed minimally invasive pulmonary valve replacement via a per-ventricular approach; however, we were severely limited by not being able to truly understand the anatomy of right ventricular outflow tract (location for placement of the stented valve). After coming to Cedars-Sinai we refined the per-ventricular approach by utilizing a 3D printed models of patients’ hearts. We were able to simulate the implant into the right ventricular outflow tract. Using 3D printing gave a better understanding of the Hybrid procedure, and allowed us to perform pulmonary valve replacement with a minimally invasive approach avoiding conventional method that required open-heart surgery.
Q: Please describe the 3DHearts Enabling A Randomized Trial (3DHEART) clinical trial. Why did you choose the patient population you chose for the trial?
A: The clinical trial is particularly exciting as it targets specific cases in which understanding of the anatomy will greatly enhance the surgical approach. A 3D printed replica of a patient’s heart will be created as part of the inclusion criteria to be in the study. While I am not a Principal Investigator in the study, I believe that the PIs have done a good job of targeting pediatric subjects undergoing primary complex two-ventricle repair of congenital heart defects to illustrate the tremendous effect 3D printing can have on our particular practice of medicine.
Q: What capabilities/technical features are needed for a 3D printer to be clinically useful in surgical planning?
A: This is a great question, but a very complex one and it unfortunately doesn’t lend itself to a simple answer. Every surgeon is different. The education, experience, aptitudes, and attitude we bring to each equally nuanced and varied patient span an almost limitless spectrum and inform how we may utilize 3D printing for the benefit of our patients. The elegance of 3D printing is that it can create the individualized tools spanning this spectrum.
That said however, what is not negotiable is the veracity of the models that we are receiving. Various materials and their corresponding coloring or rigidity may serve different functions in the hands of different surgeons, but ultimately we must have the utmost confidence in the fidelity of the models we are utilizing for pre-surgical planning. The more realistic the model is both in anatomical and textural preciousness will greatly enhance the application.
Q: What advice would you give to a hospital considering adopting 3D printing?
A: In all honesty, I would advise each hospital to start by really understanding the value proposition 3D printing offers across all specialties, and the culture of their institution. The best way to get answers to these very nebulous, complicated, nuanced directives is by retaining an outside vendor to provide as much of the services as possible, from proverbial soup to nuts.
While the MRI and/or CT data will necessarily be gathered on site, until an institution understands how 3D printing would influence their delivery of healthcare, I would recommend that, unless there is a stakeholder who can take ownership of it from the beginning, with the requisite amount of time available that it will necessarily require, I would reach out to an organization like OpHeart, a non-profit organization that can advise an institution as to how to get started.
Q: How do you see future adoption of 3D printed models for surgical planning?
A: While I do believe that the proverbial train has left the station with regards to the integration of 3D printing in the standard of care for certain types of pediatric cardiac surgeries, the speed at which it is traveling will be and the stations that it visits- that is to say, the rate of adoption and the number and stature of the centers adopting it- I believe, largely dependent on the issue of reimbursement, and the cost both in terms of financial and time. Surgeons will want these models readily available.
While I, as an individual surgeon, may embrace this technology and want to add it as a tool to my toolbox, and while the cost is relatively low in comparison to the potential costs that 3D printing may save institutions and third-party payers, I do not have the ability to pay from my own pocket for all the models which I believe offer utility.
The excitement around the 3DHEART clinical trial is so great because it is the first organized, large-scale attempt to collect evidence of the efficacies of 3D printing in the practice of medicine and delivery of healthcare, not only in terms of optimized patient outcomes, but also with respect to lower costs. If we can get reimbursement for 3D models, it is without a doubt a game-changer in terms of the practice of medicine, and a life-changer for many of our patients.
The first real heart model that will be used for 3DHEARTS pre-surgical study.
Founded in 1909, during the birth of aviation, the Paris Air Show is one of the oldest and most prestigious aerospace exhibitions in the world. Held every odd year at the Le Bourget Airport outside of Paris, hundreds of thousands of people from all over the world congregate for a week long exhibition on the latest and greatest innovations from industry titans such as Boeing and Airbus as well as over 2,300 exhibitors representing all facets of aerospace.A view from the interior of our Paris Air Show exhibition booth.

Autodesk’s Tinkercad app is probably the easiest, most accessible and most fun 3D modeling application for creating your first 3D print. No previous 3D modeling experience needed, and best of all: this 3D design app is totally free. So let’s create our first 3D print in less than 30 minutes with this beginner-friendly Tinkercad tutorial!
To get started, hop over to Tinkercad’s website. After creating an account you can directly access the browser-based app. Tinkercad will automatically start with its first tutorial. It’s recommended to follow these instructions – but you can always skip them by clicking on the ‘exit lesson’ button at the top. Choose ‘start a new project’ to get to your empty workplane.
From here, Tinkercad follows a ‘LEGO’ approach. You will mostly work with pre-defined shapes and geometric structures. You will end up adding these together or subtracting them in order to create holes or hollow objects.
The best way to get started is to click on ‘Geometric’ on the right-hand side.
Using the toolbar on the right-hand side, you can create basic geometric shapes such as boxes, pyramids, spheres, etc.. To start with, we select a box. Simply drag and drop the box from the menu to the workplane.
Once placed on your workplace, you can see a number of arrows and dots on and around your box (if your box is selected: if not, click on it now). To get a better view of the box we will zoom in with our mouse wheel. You can then turn the angle of your view with the right mouse button, and navigate around your workplane by holding down the mouse wheel (not zooming in or out, but simply keeping it pressed).
By default, our box is 20mm high. For this tutorial, we want to create a basic suitcase label with a height of 3mm. Click on the little white box on the top surface and pull it down to 3mm.
Did something not work as planned? Simply click on the ‘Undo’ button at the top of the screen to get back to the previous stage.
Next, we want our label to be more rectangular. To do this, we click on one of the black little dots at the sides of the red box. Pulling and pushing on these dots changes the size of the object. Let’s pull our object to a length of 35mm.
Next, we will add some rounded ends to this box. Therefore, we will drag and drop a ‘round roof’ on the workplane. You can find the round roof at the right-hand side next to the other geometric shapes.
Since the rounded roof is upside down, we first need to turn it. So we select the right turning arrows next to the object and turn it 90 degrees. Can’t see any arrows to turn your object? Then you need to select it first (simply click on the object).
Since the rounded roof is still not pointing in the right direction, we need to turn it again for 90 degrees on another axis.
That’s more like it! However, you will see that a part of the rounded roof is below the workplane. In order to connect the roof with our original red box perfectly, we need to pull it up first. Click on the little cone icon above the rounded roof and get it up until its bottom surface hits the workplane (the value will be 0mm).
Of course, the object is still too high. Just as we did with the box before, we can click on the little white cube on the top of the rounded roof and decrease its height to 3mm.
Now that looks much better, doesn’t it? But we still need to move the objects into the right position. Drag and drop the rounded corner right next to the box for a perfect fit.
And now we need to do the same thing for the other side of the box. In order to make things easier, we can simply copy & paste our existing rounded roof. Select the rounded roof, press CTRL+C and then press CTRL+V. A copy will appear right next to it.
So, let’s turn this copy by 180 degrees…
… and move it into the right spot.
Voila! The basic shape of the label is ready. Time to group these three items together. Select them all with your mouse and click on the ‘Group’ item on the top right corner. Your three elements will now be shown as one object. When you decide to change the size or height of the object, you don’t have to do this for each and every element separately anymore. You can always ungroup the object into several elements again by clicking the ‘Ungroup’ button.
Tinkercad is not only about adding different shapes together – it’s also about subtracting them from each other. Perfect for us, since our label still needs a hole. So let’s drag and drop the cylinder shape onto our workplane.
It’s still far too big. Let’s change its size to 5mm x 5mm x 5mm (pro tip: you can hold down the Shift key when changing the size of one dimension and Tinkercad will automatically change the size of the other two dimensions as well).
Now the cylinder has got a perfect size. Time to move it to the right location!
The cylinder is in the right place, but it’s not a hole yet. Click on the cylinder and select ‘Hole’ from the little pop-up window at the top right.
That’s exactly what we’re looking for. Let’s group the elements together by selecting both the hole and the label and by clicking on ‘Group’.
Now let’s personalize the label by writing our initials on there. First let’s tell Tinkercad that from now on, we don’t want to place new elements on the workplane, but on our label. For doing so, we need to press the W key and click on top of the label.
Voila, the new workplane will be on top of the label (it also changed its color from blue to orange). To get back to the original workplane, simply press W and click anywhere in the empty space on your screen. But for now, let’s leave it as it is.
Leave the ‘Geometric’ section on the right-hand side and change to ‘Letters’. Place your initials on the label and adjust the size.
Once again, let’s select all elements and group them together. Then we set the workplane back to its original position (press W and click anywhere in the empty space).
That’s it! And it just took a few minutes! So let’s send it to the printers. Click on the Tinkercad logo and the top left corner (no worries, your object is automatically saved).
Your new object will appear on your dashboard. You can either continue to edit it (by clicking on ‘Tinker This’), download a 3D printable file (.STL, .OBJ for instance), or send it to our 3D printing service by selecting ‘Order 3D Print’ and ‘i.materialise’. You will then be transferred to i.materialise’s 3D printing service where you can select your material (I think this would work great in rubber-like) and adjust the size of your 3D print.
This wasn’t all that difficult, was it? So go tinkering and create a 3D printable model – Tinkercad is definitely a great app to start with. And it’s more powerful than many people think. Take a look at this blog post in order to see some stunning examples of 3D printed objects created in Tinkercad. Did you already create a 3D file? Upload it here and order your print in any of 100+ materials and finishes!

Having been born in Belfast, Northern Ireland, I thought I knew a lot about all things Irish. However, having joined Terry and Diane Wohlers on a trip to the southwest of Ireland this week, I have learned a lot more. Ireland is sometimes called “the Emerald Isle,” and here in County Kerry, the landscape is so incredibly green. There is an Irish song named “Forty Shades of Green” and I am sure we have seen most of them.
There is, of course, good reason for all the beautiful green vegetation. It rains. We met a waiter who told us that from October through March, it rained every day. Every single day! Amazingly, we are enjoying day after day of blues skies, bright sunshine, and near perfect temperatures. Today is our fourth day of it. The locals say we must have the luck of the Irish. The contrast between blue sky and green landscape makes everything even more spectacular.
It is sometimes said that America and Britain are two countries divided by a common language. Here in Kerry, they may write in English but we are not sure if they are speaking it. I can nearly manage to understand the local dialect, but Terry and Diane often look bemused. However, the Irish are so friendly and helpful, and they work hard to make visitors feel welcome. They are also very proud of their country’s history, from medieval walls dating back over 900 years, to a parade of 300 vintage cars and tractors, celebrating the 100-year anniversary of Henry Ford setting up a factory in Cork, Ireland, where we spent the first nearly 24 hours.
Perhaps the most interesting (or frightening) experience we have had was kissing the Blarney Stone at Blarney Castle. It involved climbing more than 100 steps and hanging over backwards from the castle parapet to kiss a stone that supposedly endows the “gift of the gab,” that is, the ability to speak with eloquence. I am not sure Terry really needed to do this as he is already an eloquent speaker. However, we all had a go and survived the experience.
Another Irish song asks “Have you ever been across the sea to Ireland?” We now have, and I would encourage everyone to do likewise. It’s a fascinating country with brilliant green landscape and an intriguing history.
Introduction To Arduino
Everything thinks nowadays: Your car, your phone, your watch and, for the self-loathing, perhaps your toaster, too. But what is doing the thinking?
When most people imagine a computer, they might picture their trusty laptop or maybe a massive cluster of servers whirring and blinking away in a datacenter. The reality is that most of the hardware in the world isn’t being run with bulky CPUs in motherboards that have sticks of memory you can hold in your hand.
As the adoption of additive manufacturing processes continues to take hold in aviation, with leaders like Airbus incorporating hundreds of printed parts on their new generation aircraft , and Boeing production lines, we’re starting to recognize a next level of maturity in how regulations are being implemented to accommodate for these changes.
Airline carriers are beginning to use additive manufacturing to reduce inventory and alleviate supply chain constraints, but there is no better example of 3D printing’s robust and flexible usage than on the design of aircraft interiors. Many airlines understand that the accommodating comfort and offering a differentiated passenger experience are central to their customer’s loyalty and provide a lasting impression for their brand. This is one area that many carriers spare no expense or effort in order to create the refined and distinct cabin experiences that their customers demand. And while every part on an aircraft must meet strict airworthiness standards, the lower criticality of interior components allows for the effective introduction of additive manufacturing to enable customization of interior components cost effectively for the first time.
As manufacturers look to the future to define how 3D printing and connected processes can better meet their business demands and reduce supply chain complexities, the task of certifying a part within this changing environment can be overwhelming given the lengthy process and the many steps that are required to meet airworthiness regulations. Understanding the process can greatly enhance the outcome and reduce unnecessary delays or frustrations. The FAA is working with aviation and business leaders to help remove some of this friction by tailoring certification tracks that meet the needs and demands of the fast changing industry. In the case of additive manufacturing, we have leveraged decades of process development in the composites manufacturing space, to chart a very similar course for the certification of 3D printed parts.
In conjunction with America Makes, industry partners, and the National Institute for Aviation Research, and under the oversight of the FAA, we have launched the qualification of the Fused Deposition Modeling technology on a new configuration of the Fortus 900mc. The result is a highly repeatable process, with full documentation and traceability, and a B-Basis Allowables database that will speed certification of FDM parts for aircraft interiors around the world.
