The 3D Printed Shelby Cobra at NPE 2015

The 3D Printed Shelby Cobra at NPE 2015

The National Plastics Exhibition, or NPE, happens every three years in Orlando, Florida.  The fact that it is dubbed National is besides the point, there were companies from around the world showcasing their new technologies.

I was graced with the opportunity to attend as part of my PhD studies for 3 days and I have to say it was overwhelming.  According to their website, NPE 2015 was to be attended by over 2,000 companies and 60,000 plus industry professionals. 

NPE's focus for the show included 3D printing, recycling, bioplastics, nanotechnology, and business startups.  Every single topic I am very passionate about. 

There was even a giant mobile of 3D filament spools as we went down the escalators to the show floor.


For those who do not know my Bachelors degree is in Nanotechnology Engineering and I studied Nano-Bio-Composite Plastics for my Masters thesis; 3D printing is now the focus of both my PhD and Structur3D. Go figure!  

Because of the 3D printing focus, I was given another opportunity to see the worlds first full-size 3D printed electric car, a 50th anniversary Ford Shelby Cobra.  The rebirth of the 3D Shelby was thanks to a collaboration between TechmerPM and Oak Ridge National Labs (ORNL) as a part of Obama's $259 million dollar investment into additive manufacturing.  Obama even got to take the first peek inside.

The 20% carbon reinforced ABS was formulated by TechmerPS and printed on the ORNL Big Area Additive Manufacturing (BAAM) printer.  Motivation for the project comes as part of a US Department of Energy project attempting to print components 10 times larger and 200-500 times faster (in volume) than previously capable with FDM technologies.


Taking a closer look at the 3D printed car, it has a much more complete finish than the Local Motors Strati printed on the same machine.  That is to be expected, as the Shelby Cobra project is demonstrating a high end application, whereas the Strati wants to embrace the 3D printing process.  The surface finish is considered Class A. That being said, upon closer inspection you can see the artifacts of 3D printing (maybe on purpose).  

Have a look at the gallery below to see the 3D printed Shelby Cobra up close. There even appears to be some additively manufactured metal pieces hidden in the design.


Overall, I love the design! Now I just need to see it run to prove it is more than a super-golfcart.

The Shelby Cobra wasn't the only 3D printed car at NPE, my old friend the Local Motors Strati was on display.

Read what I had to say about the process of 3D printing the Strati (it was made on the same Oak Ridges National Laboratory printer) and my chance to take a test ride HERE.

 

I would love to hear what you think of 3D printed cars. Are they here to stay? Or just a fad? Perhaps there is a special use we haven't thought of yet.  Feel free to comment below.

Structur3D does Midwest RepRap Fest 2015

Structur3D does Midwest RepRap Fest 2015

Last weekend, March 20-22, my brother and I attended MRRF 2015, which I now know is pronounced 'MERF 2015,' not M-R-R-F. Boy did we have a great time with fellow RepRappers and 3D printing companies.

The turnout over the 2 days was over 600 people and most of them decided to set up a demonstration of their passion for the 3D print world. There was everything from graphene nanomaterial suppliers to the famous 15' SeeMeCNC PartDaddy pumping out 4' garbage containers.  Exciting!

Instead of trying to describe the event to you, we have put together a couple videos showing some cool technology and the excitement of the event as well as an album of over 100 photos from MRRF. I hope you enjoy even a fraction of the amount I did.

Here is Spiderman being drawn on a delta style 3D printer at the RiverCityLabs.org table, built by member Jay B.

Here are some photos taken by Adam and I of things around the show we loved.  Turns out we took pictures of pretty much everything.

To give an idea of the crowd at MRRF, here is a brief timelapse at our table.

Printing, Making, and Driving the Local Motors Strati 3D Printed Car

I had the opportunity to attend the North American International Auto Show this past Friday in Detroit, and boy was I in for an awesome surprise.  One of the vehicles catching all of the headlines was the Local Motors Strati - an electric car with a fully 3D printed body.

They were actually manufacturing cars right on the show floor! I will now share with you some of the manufacturing magic I was presented with.

How to 3D Print a Car 101

The 3 stage process was well displayed including 1) 3D Printing, 2) Part Finishing, and 3) Car Assembly.  The material used in the FDM style 3D printer is ABS plastic reinforced with carbon fibre - a very stiff and durable material great for automotive parts.

Take a look at the images below to follow the process from start to finish.

The Finishing Touches on the 3D Parts

The cars on display show both finished and unfinished parts to pay homage to the fabrication technique, but this is not required.  LM has optimized the parts finishing to make them look uber-shiny.  First the 3D printed parts are CNC milled into the proper tolerances, then they are sanded smooth.  Finally, paint or just some plain old elbow grease will make the parts road ready.  See below for some up close photos.

My First 3D Printed Ride!

One thing I did not expect from my trip was that I would actually get to take a ride in the 3D printed car.  I managed to get the last spot in line for a spin around the track in the first ever production Strati, boy was I lucky (and a little giddy).  I managed to get a great selfie and a couple videos racing around the track, make sure to check them out.

10. Conductive Inks (like the Bare Conductive we 3D printed)

9. Polyurethane (its great for gasket applications)

8. Wood Filler 

7. Ceramics

6. Nutella (we printed at Maker Faire Bay Area in 2014)

5. Clays

4. Sugar (our May the Fourth Cake Toppers)

3. Chocolate

2. Silicone...

Adventures in Paste Extrusion: Printing Playdough at Maker Club

Playing around with molten plastic isn't a particularly popular past time for children. Play dough on the other hand, is something almost every child experiences in their early maker projects.  

So, if you want to introduce kids to 3D printing, it makes sense to do it with materials that they already know and love. 

Last week we were invited to take part in the monthly meeting of the Kitchener-Waterloo MakerClub, a group of kids (and their adults) who get together once a month to explore the joys of making.

We decided to try out printing with play dough for the first time, and we made this video of it.

4 Reasons We Created an Add-on Extruder Instead of Yet-Another-3D-Printer

A bit of background on why we chose to create an add-on paste extruder, instead of creating a whole new 3D Printer.

In case you're not familiar with Structur3d and what we do: We're just days away from launching our first product, the Discov3ry. It's a universal add-on paste extruder for 3D printers, which can be easily integrated with virtually any filament desktop 3D printer out there.

The 17 Most Exciting Startups at the 2014 Maker Faire

The Bay Area Maker Faire is ground zero for the cutting edge in DIY and maker technology. It's the place to go to see the future of democratizing technologies, that distribute the means of production.

We're super thrilled to be unveiling our new Discov3ry Universal Paste Extruder at the event, but we're almost as excited about all the other awesome startups we'll be sharing the experience with.

One thing we noticed, was that there wasn't much detail given about the startups that were chosen to exhibit and what they've been working on. So we put together a list our selves.

A Manifesto for the Maker Dads and Maker Moms

UPDATE: Charles' Maker Manifesto was picked up by CTV News Kitchener on Saturday, May 10th, 2014.  Check out the story here.

 

Structur3d's president and co-founder Charles Mire, is both a passionate maker, and the proud father of two young daughter's.

"My girls aren't fans of Miley Cyrus or Justin Bieber... they play with Tonka trucks ... "  

Charles and his wife Michelle want their two young daughters to grow up with interests in Science, Technology and Curious George. 

If you believe in empowering children to realize their own creations by teaching them the tools of making... If you're a Maker Mom or a Maker Dad, watch enjoy and share Charles impassioned call to action:

I Am A Maker Dad
