NW Rapid Manufacturing Produces a Fuel Tank for Oregon State University’s Formula SAE team!

SLS Fuel tank manufactured for Oregon State University's Formula SAE team, by NW Rapid Manufacturing

This past week, Northwest Rapid Manufacturing had the pleasure of presenting the team with a 3D-printed fuel tank. This “rapid prototype”, made of tough and durable nylon is perfectly suited for the harsh conditions of racing.

The “additive manufacturing” process allows for wall thicknesses, radiusses, reinforcement bosses, slosh baffles, and mounting points all to be maximized to each unique part’s function and stress level.

Rather than being assembled from a multitude of individual parts, this fuel tank comes out of the EOSint P730 SLS machine in one piece!

At the RAPID 2010 Conference

Sunday, May 23rd, 2010

Catching up back in the office and wanted to take a moment to share my experience at this year’s RAPID Show in Anaheim, CA at the Disneyland hotel. I always find it very important to get out of the office and gain new perspective. It’s also great to share ideas and get the feedback that you are doing valuable work! My week went a bit like this:

First, I arrived in Anaheim with my wife for the weekend. We are both hard working professionals, so this was a nice way to force a vacation :)   Of course we are both engineers, so in order to see all the attractions most efficiently, my wife downloaded some software which gives an optimized plan based on day of the week and time of year. What this did not take into consideration was the weather…it was colder than Oregon :(  Good thing was the parks were not so busy. Quick tip: Don’t ride Splash Mountain if there is any risk of not seeing the sun.

Anyway, we still had a blast. I must mention that I found 3D printed parts from a Z Corp machine in one exhibit http://video.google.com/videoplay?docid=-5629398988870350309#

After dropping my wife off at the airport early Monday morning, I prepared for my presentation at the EOS NAUD (North American User Day). EOS talked about their new materials (including PrimePart ST) and systems (including the P760 and P395). I educated the group of laser sintering users about the good work we are doing in the UAV Industry. Everyone was impressed with the stability of our thin wall parts. Unfortunately, SLS sometimes gets a bad name because there are some pretty low quality parts on the market. We have the expertise and well-maintained machines to create strong parts with walls as thin as 0.50mm or 0.020” in certain materials. The 1mm wall fuel tank which has held 10psi of pressure for the last year was particularly impressive.

The next day, I spoke at the SME (Society of Manufacturing Engineers) RAPID Show to a group specifically interested in aircrafts. The sample parts were again a hit. I had the opportunity to educate some folks on the fact that polystyrene models can be created using laser sintering. I showed some examples of aluminum castings made using this process (though Titanium, Stainless, etc. can also be cast using this process). I was excited to see folks from Boeing, Northrop Grumman, and the Army.

On the last day of my trip, I had the honor of mentoring in the SME Bright Minds program where high school student are introduced to the Additive Manufacturing Industry. Many experts were in the room which lead to some great presentations and conversations. Of note was Mike North’s presentation which includes many of his adventures both caught on film and behind the scenes. All of the students and mentors were pretty excited about the AMP=D Electric 33 Hot Rod from Factory Five http://www.youtube.com/watch?v=kpqvpqklyk0

In general, it was so fantastic to see so many old friends and colleagues and meet some new ones as well!

Stay tuned as we have some exciting collaboration including a potential material breakthrough quite soon…

Growing an Industry, Layer by Layer presented at the RAPID 2010 Conference

Growing an Industry, Layer by Layer

The UAV market has grown and so has Northwest UAV Propulsion Systems. Adding to the growing pains of entering a new market and supporting new designs, purchased prototype parts were received with varying quality and lead times. Rather than being discouraged by the experience, Chris Harris saw the potential and was empowered to bring laser sintering in house, getting control of their process chain.

Northwest Rapid Manufacturing was formed with a focus on producing durable, thin-wall plastic parts on their EOS P390 and has done so for more than a year. With new projects and applications in mind and no machine capacity, an additional EOS P730 large frame laser sintering system was purchased. Northwest UAV now leverages Northwest Rapid Manufacturing to produce production level parts (overnight when necessary) to support various projects including small engine and variable pitch propeller development.
Northwest Rapid Manufacturing continues to build on its core competency while utilizing new materials (including polystyrene for casting metal parts) and producing single piece large parts including fuel tanks.

Join us for Alex Dick’s presentation at the upcoming Rapid 2010 Conference!
