Standard Roof Rack Fairing Mount Getting In Your Way?! Engineer it better and 3D Print it!

It is no mystery that I love my Subaru. I bought it with the intention of using it and I have continually made modifications with a focus on functionality.

When I bought my roof crossbars in order to mount ski and/or bike racks, I quickly realized I needed to get a fairing in order to reduce drag and wind noise. The fairing functions as designed, and looks great as well. However, when I went to install my bike rack, I noticed that the fairing mount was in the way of mounting at the tower. As a result, I had to mount the rack inboard of the tower by a few inches. This mounting position had a few negative results:

  • The bike was slightly harder to load/unload
  • The additional distance from the tower resulted in additional crossbar flex and bike movement
  • Additional interference between bikes when two racks are installed

These issues could all be solved if the fairing mount was simply inboard a few more inches. If only I had access to the resources to make such a concept a reality…. oh wait, PADT has all the capabilities needed to take this from concept to reality, what a happy coincidence!

First, we used our in-house ZEISS Comet L3D scanner to get a digital version of the standard left fairing mount bracket. The original bracket is coated with Talcum powder to aid in the scanning process.

The output from the scanning software is a faceted model in *.STL format. I imported this faceted CAD into ANSYS SpaceClaim in order to use it as a template to create editable CAD geometry to use as a basis to create my revised design. The standard mounting bracket is an injection molded part and is hollow with the exception of a couple of ribs. I made sure to capture all this geometry to carry forward into my redesigned parts, which would make the move to scaled manufacturing of this design easy.

Continuing in ANSYS SpaceClaim, as it is a direct modeling software instead of traditional feature-based modeling, I was able to split the bracket’s two function ends, the crossbar end and fairing end, and offset them by 4.5 inches, in order to allow the bike rack to mount right at the crossbar tower. I used the geometry from the center section CAD to create my offset structure. A mirrored version allows both the driver and passenger side fairing mount to be moved inboard to enable mounting of two bike racks in optimal positions. The next step is to turn my CAD geometry back into faceted *.STL format for printing, which can be done directly within ANSYS SpaceClaim.

 

After the design has been completed, I spoke with our 3D printing group to discuss what technology and material would be good for these brackets, as the parts will be installed on the car during the Colorado summer and winter. For this application, we decided on our in-house Selective Laser Sintering (SLS) SINTERSTATION 2500 PLUS and glass filled nylon material. As this process uses a powder bed when building the parts, no support is needed for overhanging geometry, so the part can be built fully featured. Find out more about the 3D printing technologies available at PADT here.

Finally, it was time to see the results. The new fairing mount offset brackets installed just like the factory pieces, but allowed the installation of the bike rack right at the tower, reducing the movement that was present when mounted inboard, as well as making it easier to load and unload bikes!!

I am very happy with the end result. The new parts assembled perfectly, just as the factory pieces did, and I have increased the functionality of my vehicle yet again. Stay tuned for some additional work featuring these brackets, and I’m sure the next thing I find that can be engineered better! You can find the files on GrabCAD here.

 

Metal 3D Printed Shift Knob: Is It Cool(er)?

I had a really great time designing the Metal 3D printed shift knob from my previous blog post. I was curious what the other benefits of the knob may be besides being cool to look at and show off. What better way than to use the simulation software that we use here at PADT every day!

One of the clear differences between my solid spherical knob and the Metal 3D printed version is surface area. Being that PADT is based in Tempe, AZ, some may say that we have “warm” summers down here. Couple the 120F days with a black car, and the interior can get very hot, at some points feeling like the sun itself has taken up residence inside the back seat. With modern A/C, this heat can be mitigated fairly quickly, only to attempt to shift into gear to be scalded by the shift knob!

I wanted to see what the rate of cooling for the two knobs would be in a basic situation with some basic assumptions. Using ANSYS transient thermal, I initialized the knobs to 150F, temperatures that can be quickly reached in parked cars here in AZ. I added a convection heat transfer boundary condition on the outer surface of each shift knob, assuming a film coefficient of 50 W/m^2C, and that the ambient temp in the car is at a cool 70F.

 

I ran the simulations for 5 minutes, and the results were in line with what I expected. As the 3D printed knob has more surface area for cooling, it’s final temperature was ~84F, compared to the solid spherical knob at a final temperature of 115F!

Reveling in Speed and Technology – Tesla Test Drive Day at PADT

We have great customers.  The kind of cusomers that call up and ask “Hey, what do you think about having a Tesla test drive event for PADt employees”  Duh.  Yes.  Please provide contact information.

Then we thought this was an event better shared with other techno-speed-nerds. The Tempe Tesla show room people liked the idea so we put together an event for our ANSYS and Stratasys customers. (Just another reason to buy from us)

The basic idea was simple, stop on by the PADT parking lot in Tempe and drive a Tesla Model S or Model X, or both.  The Tesla people brought along their technical person and the test drive people were also very knowledgable about all the features in the three vehicles they let us drive. The course left the PADT parking lot, drove up to Elliot, then entred to 101, and then get off at Warner or Rey and head back, while the brave Tesla employee tried to keep cool. Especially when Oren was driving.

For many of us, this was the first time we had driven one.  Let me just say that the common factor across employees and cusotmers is that everyone had an ear-to-ear grin on their face when they got back from their test drive.  These cars are not just fast (large numbers of electrons pushed through big motors equals lots of torque right away) but they are brilliantly engineered. From the user interface, to the seats to, to the suspension. Everything is done right.  As a group of engineers that was almost as exciting as the raw power and impecable styling of the cars.

It was a true nerdfest.  We spent 10 minutes discussing regenerative breaking schemes and the idea of using regeneration all the time when you lift off the accerator instead of putting your foot on the break to slow down slightly.  This is the type of paradigm shift that disrupts around one hundred years of automotive legacy.  Why does the accelrator pedal have to be an accelerator pedal. Why can’t it be an input for acceleration and deceleration based on position?  We also spent even more time (I’m embarassed to say how long) talking about charging.  And then the topic turned to autonomous driving and the sensors used.  Good times.  Good times.

PADT’s relationships with Tesla actually goes way back. When they were first starting out and were just a handfull of engineers, we provided some ANSYS training and did a consulting job for them on thermal management for an early battery system.  So we proudly count them as a happy PADT customer.  And of course PADT worked on the large Blink chargers and has supported many companies that are suppliers to tesla.

Look for similar events in the future. No sales or seminars, just smart-people-fun type of events. 

 

Phoenix Business Journal: ​Voice recognition, the new thing in computing

Let’s be honest, the mouse and keyboard are outdated interface methods that serve us well, but voice recognition is pretty dang awesome and efficient. In “​Voice recognition, the new thing in computing” I write an entire post using voice recognition about the pros and cons of voice recognition.  That is almost meta. Please enjoy, it was a fun one to do.

Christmas Left-Right Gift Exchange Story: Western

For our Christmas parties at PADT we generally have over 40 employees so a traditional secret Santa gift exchange takes to long. So a couple of years ago we downloaded a right-left gift exchange story from the internet and it was a big hit. We ran out of stories on the internet, so we started writing our own, usually in some sort of over-the-top style.  This year, 2016, many of us had become addicted to West World, so a good old fashioned Western seemed appropriate.

Everyone gets their gift and forms a big circle in the middle of the room.  Someone with a strong voice reads the story and every time the world LEFT is read, everyone passes the package they have to the left. Every time the world RIGHT is read, everyone passes the package they have to their right.  You should pause a bit at each LEFT/RIGHT to give people a chance to pass.

Trixie and the Christmas Miracle

A train whistle echoed in the distance as US Marshal Dilan McRightland brought his horse Righty to a stop on the left side of the ridge. Down below, right in the middle of the valley was his destination, the place he had been headed right towards for three weeks. Wrightville Gulch. He’d seen a lot of dusty towns, not much more than a few buildings on the right and left side of a crooked street. Left to his own devices he would have left his job and gone right back to his family farm on left bank of Ohio river, right below Louisville Kentucky. But he had sworn an oath to uphold justice, to make sure that wrongs were righted, and that no criminal was left free to cause more harm. It was the right thing to do.
He dug his heals into Righty and they headed right down the trial, towards an encounter that would have been best left alone.

As he entered the town from the… south, he surveyed both sides of the street. On the right was a bank, livery stable, and what looked like a hotel that may not be where the ‘right type of people’ stay. The other side of the street held a saloon, blacksmith, general store, and a Chinese restaurant: Right and Wrong Noodles. Dilan assumed that the fugitive he was seeking was in the saloon. So he tied up Righty, using a left hitch not, and went right in the swinging doors.

It took a while for his eyesight to adjust to the dim interior. A long mahogany bar filled the wall. On the… other side, there was a stair case that led to rooms on the second floor. Right in the middle of the room stood a giant Christmas tree. That was right, Dilan thought, today was Christmas Eve. It has been a long time since he had enjoyed a right proper Christmas. He began to day dream about snowy Christmas mornings when a shout brought him right back to reality.

“Hey! You looking for me, stranger?” A man dressed in head to toe in black leather stood on the left side of the Christmas tree. “If you are Lefty Peterson, then yes.” Replied Dilan. “I’m US Marshal Dilan McRightland and I’ve traveled all the way to Wrightville Gulch, right here in the middle of no-where, to bring you to justice.”

The two men stared at each other across the room, their right hands hovering over their six shooters, which for now were left in their holsters. “I don’t think you have it right, Marshal. When I left the Stanton brothers for dead, right in the middle of Dodge City, I left that life behind me. I’m clean now, I’ve got a wife and kids. I started over. You know what I did was right, they deserved to die. So the right thing for you to do is get back on your horse and get right out of town.”

This left Marshall Dilan a bit baffled. What if Lefty was right? And then he stood up straight and looked Lefty in the eye. “The law is the law lefty, doesn’t matter if you think what you did was right, it is up to a jury to decide that.” Lefty looked right back, and snarled “The only way you are taking me back is as a corpse. If you don’t leave in a coffin yourself. Their right hands slowly moved to their guns.

Just when they were about to draw a girl dressed like a dancer the left bank of the Sein in Paris, dashed right between them. “Stop right now!” she shouted. “Gosh Nabit! It’s Christmas Eve. Have you any heart left, either of you?” She turned to Lefty “Lefty, darling, you don’t have to die. If you think what you did was… justified, go with the marshal, argue your case.” She spun to face Marshall McRightland “And you, you come riding in here on Christmas ever, where we was having ourselves a right nice party, and you threaten our friend Lefty, that just aint right either!”

Dilan stood. He could see the star on his chest reflected in the mirror behind the bar, and he could see the star right on top of the tree. And he looked right at the dancing girl, a small tear falling from her right eye. “Lefty” he said “you agree to let me handcuff you to that bar there, and we can have ourselves a right proper Christmas ever and morning. And then we ride out of here and you get your day in court. Does that sound…. All right?” Lefty thought for a minute, then responded “I right reckon that is the right thing to do. Right here and right now on Christmas eve, maybe some peace on earth is what we need.”

And so on that Christmas Eve in a dusty town right in the middle of no-where, a little Christmas spirit, and a fiery dancing girl named… Trixie, brought a little peace on earth and goodwill towards men to a place called Wrightville Gulch.

Metal 3D Printing a Shift Knob

I have always had an issue with leaving well enough alone since the day I bought my Subaru. I have altered everything from the crank pulley to the exhaust, the wheels and tires to the steering wheel. I’ve even 3D printed parts for my roof rack to increase its functionality. One of the things that I have altered multiple times has been the shift knob. It’s something that I use every time and all the time when I am driving my car, as it is equipped with a good ol’ manual transmission, a feature that is unfortunately lost on most cars in this day and age.

prevknobs

I have had plastic shift knobs, a solid steel spherical shift knob, a black shift knob, a white shift knob, and of course some weird factory equipment shift knob that came with the car. What I have yet to have is a 3D printed shift knob. For this project, not any old plastic will do, so with the help of Concept Laser, I’m going straight for some glorious Remanium Star CL!

One of the great things about metal 3D printing is that during the design process, I was not bound by the traditional need for a staple of design engineering, Design For Manufacturing (DFM). The metal 3D printer uses a powder bed which is drawn over the build plate and then locally melted using high-energy fiber lasers. The build plate is then lowered, another layer of powder is drawn across the plate, and melted again. This process continues until the part is complete.

The design for the knob was based off my previously owned shift knobs, mainly the 50.8 mm diameter solid steel spherical knob. I then needed to decide how best to include features that would render traditional manufacturing techniques, especially for a one-off part, cost prohibitive, if not impossible.   I used ANSYS Spaceclaim Direct Modeler as my design software, as I have become very familiar with it using it daily for simulation geometry preparation and cleanup, but I digress, my initial concept can be seen below:2016-10-18_16-19-33

I was quickly informed that, while this design was possible, the amount of small features and overhangs would require support structure that would make post-processing the part very tedious. Armed with some additional pointers on creating self supporting parts that are better suited for metal 3D printing, I came up with a new concept.

2016-10-18_16-24-24

This design is much less complex, while still containing features that would be difficult to machine. However, with a material density of 0.0086 g/mm^3, I would be falling just short of total weight of 1 lb, my magic number. But what about really running away from DFM like it was the plague?

2016-10-18_16-23-31

There we go!!! Much better, this design iteration is spec’d to come out at 1.04 lbs, and with that, it was time to let the sparks fly!

img_7602

Here it is emerging as the metal powder that has not been melted during the process is brushed away.

The competed knob then underwent a bit of post processing and the final result is amazing! I haven’t been able to stop sharing images of it with friends and running it around the office to show my co-workers. However, one thing remains to make the knob functional… it must be tapped.

img_7762

In order to do this, we need a good way to hold the knob in a vise. Lucky for us here at PADT, we have the ability to quickly design and print these parts. I came up with a design that we made using our PolyJet machine so we could have multiple material durometers in a single part. The part you need below utilizes softer material around the knob to cradle it and distribute the load of the vise onto the spherical lattice surface of the knob.

img_7765img_7764

We quickly found out that the Remanium material was not able to be simply tapped. We attempted to bore the hole out in order to be able to press in an insert, and also found out the High Speed Steel (HSS) was not capable of machining the hole. Carbide however does the trick, and we bored the hole out in order to press in a brass insert, which was then tapped.

Finally, the shift knob is completed and installed!

First Perfect Pitch Startup Presentation Competition a Success – CEI Takes Home the Unicorn Cup

perfect-pitch-16-all-2The verdict is in, if the company barq! actually existed they would have raised a lot of seed money yesterday.  Members of the Phoenix area startup community gathered at PADT to try out a new idea: what if the experts who mentor and coach startups tried their hands at pitching a company?  The result was fun, funny, and educational.

title-slides-perfect-pitch-2017Local incubators/accelerators CEI, Seed Spot, and Tallwave joined PADT in pitching a totally made up company, barqk! to a group of judges who are startup experts.  We talked about poop, doggy depression, bessel functions, big data, valuations, and the cat revolt. In the end we ended up with four fantastic examples of how to pitch a company and how to answer questions from investors.  One of the best parts was that every single team finished their pitch in the 10 minutes they were given, and they covered everything that needed to be covered. Yes, it can be done!

And the winner is… The Center for Entrepreneurial Innovation (CEI).  Tom Schumann and Patti DuBois told a story, explained the product, and got across the value to the investors of the product

.  perfect-pitch-16-winners-text

You can watch the recording of the presentations in the video below.  Take some time to watch the pitches and get a feel for barqk!, and how different organizations approach telling the story and more importantly, attracting investors.  The audience noticed that each team had a unique take that represented their strengths.

Our judges were Jim Goulka from Arizona Technology Investors, Christie Kerner from ASU, Carine Dieude of Altima Business Solutions, and Linda Capcara with TechTHiNQ, and they did a fantastic job, especially with keeping a straight face when the contestants responded with some very inventive responses. Their contribution was important.

If you are interested in doing a similar event, here is some background information:

barqk-logo-200-1Rules:

  • Each team gets a copy of the angel group funding application and a logo.
  • Each team gets 10 minutes to pitch
  • The judges have up to 5 minutes to ask questions
  • The other presenters can listen in
  • PowerPoint slides are allowed
  • Some variation from the company application is allowed for humor or to fill gaps, but everyone should stick to the same basic material

Here is their angel funding application, everything you need to know about them is in there: barqk-angel-application-1.pdf

We look forward to doing this again, hopefully as part of a larger startup event. Thank you to all who participated by pitching, judging, or being in the audience.

Engineering a Better Pokemon Go Experience

padt-pikachu-1The other day, I saw a post on Engadget about a special case for Pokemon Go users to solve the problem of missing your prized Jigglypuff that you have happened across in the wild (or let’s face it, probably a CP 10 Rattata who is going to break out multiple times before disappearing in a puff of smoke…). The case is designed to give the user access to on screen controls and a nice channel to keep your Pokeball flinging finger straight and true.

Pokemon Go Photo 0
Original Device designed by Jon Clever

As pointed out in the article on Engadget, this case is only useful in the capture screen. This caveat aside, the other issue with the case is that it obscures the screen. Here at PADT, we are fortunate to sell a wide variety of 3D Printing machines, some of which are capable of multiple colors and material durometers. I decided to design my own take on the case from Jon Clever to be prototyped on our Stratasys Connex 3.

Pokemon Go Photo 1

Pokemon Go Photo 2

The case was made with black and clear material. The black material can be combined to produce a custom stiffness, so we made that part soft and rubber like and kept the clear portion rigid. The clear has good optical quality, which could be increased with a layer of “clearcoat.”

Pokemon Go Photo 3

If you have a Stratasys Connex 3 or J750 and an iPhone 6, you can make your own with these STL files, one for the rubber part and one for the clear part.

Other variations and additional possibilities would be made possible with the new Stratasys J750, the first true full color printer that can also mix clear and solid as well as hard and soft materials.  The J750 was just released and highlighted on our recent road show. Visit our blog article on the Scottsdale show to learn more about this incredible printer.

Sometimes it is only about speed! Team building at the Kart track

SIMSAL-2016_06_14-Racing-3Every once in the while you need to get out of the office and run your co-workers off a track. For whatever reason, when members of our Sales and Support department put on some helmets and strapped themselves in to electric racing karts, they got very competitive.

The people who sell and support 3D Printers and Simulation software left their Stratasys and ANSYS brochures at home and headed to the Octane Raceway in Scottsdale, AZ for some fun and decompression. They have been working hard all year making customers happy, and they needed a way unwind.  So the drove in circles.

Fun was had by all. Only a few curse words were exchanged. Mario was asked to get a more subtle shirt.

The only disappointment is that the winner of the event was Oren Raz… most of us back at the office were pulling for Clinton Smith to take the trophy.

Spinning Gears: 3D Printing Awards for 2016 AZ SciTech Festival Sponsors

SciTech-Festival-Award-2016-2For several years now PADT has 3D Printed special thank you awards for the fantastic companies that sponsor the Arizona SciTech Festival.  This year we decided to stick with the color of the Stratasys Connex3 but add some moving parts. This gear design spins around and was made as one part, we just wash the support material out of the gaps between parts.

This is a great example of going directly from a CAD model to a custom part.  Each award has the recipient’s name printed on the smaller gear.  Everything was designed in an hour or so and it took about another hour to add in the 30 or so names.  We think these may be the best awards we have made so far.

Kids, Pizza, Engineering – A Fantastic SciTech Festival Open House at PADT

ScitechFestivalLogoWe thought we would open PADT’s doors to families and maybe a few people would stop by. Over 250 people did just that.  What a great evening of smiling kids and adults enjoying the excitement of engineering.  Exciting engineering? Yes, we know enough to not talk about quality system protocols, matrix inversions, and non-linear turbulence model convergence. We stuck to 3D Printing, elephants on skateboards, and 3D scanners. And we fed everyone pizza.

FullSizeRenderIt was a great evening where everyone learned something.  The focus was on exposing what engineers do, what PADT does, to people who may not be technical. Mostly kids but we also saw it as a way for engineers to show their family members and friends what engineering is about.  The results far exceeded our expectation, mostly because of how great everyone who showed up was.

Some of the quotes from people who have emailed to thank us are:

“Thank you for opening up your office to me.  What a cool place!  Even though I have been familiar with and worked with 3D printing for 20+ years, it is always nice to see the new technology, products, and the output of the products. “

“… to see my son and all of the other kids so excited and amazed was truly awesome. Mason told me it was the best night of his life! And this morning his first words to me where thanking me for taking him to the event and when can we go back.”

“This is such a great opportunity for me to show my grandkids what I spent my life doing, and seeing them get so excited about it is wonderful”  

The best part of the event for most of us here at PADT were the fantastic questions.  As one of our engineers said “for 2 hours I was just lost in the joy of positive human interaction.”  We do love what we do here, but it was nice to share it with other people.

Below are some pictures from the evening.  Make sure you sign up for PADT’s email list to get invites to future events.
