Signs of Building Momentum Underscore 2014 AZ Tech Council CEO Retreat

ceo-retreatWhen you get an invite for a “CEO Retreat” the word boondoggle tends to come to mind.  But this is Arizona and we like to have fun here, but we are also a very practical and hard working people, so even a retreat in Sedona is a value added experience.  Hosted by the great staff of the Arizona Technology Council, the 2014 CEO Retreat was a useful and enjoyable event. 

This year the full event was held at L’Auberge de Sedona, truly one of the nicest spots in Sedona, what may be one of the coolest places in the state.  The reception Monday night was a great chance to catch up with everyone, meet some new people, and touch base on what happened in the previous year.  It was also the first time I noticed what would become a common theme – there is a growing momentum  in the Arizona technology community.  During the seminar the following day, that same theme grew louder and stronger.

For a long time the technology business community in Arizona has been fragmented and focused outside of the state.  Housing and real estate are huge business here and it is sometime forgotten there is a diverse and significant number of high technology businesses here.  

Sedona has so many incredible views, you find yourself staring out the window with your jaw dropped a lot.

Sedona has so many incredible views, you find yourself staring out the window with your jaw dropped a lot.

After talking with other business owners or C-level people, it became obvious that business large and small are seeing good steady growth. Larger companies are doing more and more of their work here in state, and moving more of their operations to the state.  I learned how one of Arizona’s most successfully tech companies has quietly added significant services offerings to their long term business model that is allowing them to grow beyond their traditional business.  I also chatted with several small software companies that are making that transition from start-up to growth company, adding jobs and talent.  And the impact of data centers and providing services and infrastructure for “the cloud” was obvious and significant on the overall community. One of our favorite segments, Aerospace was a bit underrepresented. So I used every opportunity to point out how well Orbital Sciences is doing with its rocket programs, Honeywell is creating an Additive Manufacturing (3D Printing) Center of Excellence here in the valley, and a handful of smaller companies are making significant strides in UAV technology.  I didn’t really have time to talk about all the great Cleantech companies we know about.

This growing momentum was best expressed when a Silicon Valley insider and a guest from San Diego both commented on how something important and significant is going on with the Arizona technology community. 

In between such discussions we had a great sessions  learning about funding opportunities and strategies for capital, suggestions for finding great employees, resources for start-ups, tips for digital marketing, and much more. We finished with a great workshop on creating meaningful content to establish your company as domain experts.  

There was golf the first day, but I decided to not drag the PADT name down in shame.  Instead I enjoyed sitting on the hotel patio and watch the rain come down.  It has been a hot summer here in Phoenix and enjoying nature air conditioner was much better than loosing little white balls in the cactus.

Rain falling on Oak Creek from the Hotel Patio.  The Temp dropped to around 65F and then the sun came out.

All-in-all a great event, at a great location, with great people.

3D Printed Quill Pen for GISHWHES 2014 Scavenger Hunt

quill-pen-2Sometimes you get strange messages on Facebook.  This weekend I heard a beep and checked my phone “Can you 3D Print a Quill Pen?”  Most messages involve asking me why I posted something stupid or annoying, so this one caught my attention.  Turns out my friend Chelsea is taking part in the 2014 “GREATEST INTERNATIONAL SCAVENGER HUNT THE WORLD HAS EVER SEEN” or GISHWHES.  One of the items in the scavenger hunt is to print out an ink quill pen on a 3D Printer and write “We need to buy more Toner” on a sheet of paper with the pen.  

I can’t resist a challenge like that, so I told her no problem.  And it worked like a charm. 

The process we used was very straightforward:

First I went into a CAD program, SolidEdge in this case, and build a solid model of a quill pen.  Not being quill pen designer I found some web sites on how to cut a pen tip from a real feather, and tried to mimic the resulting geometry:

Quill-Cad-Model Pen-Tip-Quill-Pen
We then wrote an STL file out and sent that to our RP team.  They read that into our preparation software and separated the feathers from the stem, designating a rubber like material for the feather area for artistic purposes, and a hard white plastic for the stem and the tip.

That file was then sent to our Stratasys Objet500 Connex3 and printed in about 30 minutes.  

This video shows the printing process:

Once it was done, we just needed to wash out the support material and it was ready to go.

The moment of truth was then here.  Our intreped Scavenger Hunter took out her handy-dandy pot of India Ink and dipped the quill in, the she wrote out the requested message:
quill-pen-2

I worked like a charm, our handwriting was the biggest issue.

Wanting to see if it enhanced my artistic skills, I used it to sketch the following masterpiece:
quill-pen-face

This is why I use CAD systems.

Here is an image of the final part. The tip is stained black from the ink.
quill-pen-4

All and all a fun project, and I guess the team gets 80 points for doing this task, so we were glad to help.

Talking About 3D Printing on Talk Radio

radio-microphone-on-the-airWith the increase of interest in 3D Printing from the general public, PADT has been asked to speak about the technology over several different forms of media. The local Phoenix TV stations were kind enough to come in and learn about the technology, including a great interview on the local PBS station.  We have been asked to give presentations to schools, inventor groups, and even a conference on traditional digital printing. Last week we crossed over into a new area for us, talk radio.

Don’t worry, this was not political talk radio… we are still waiting for Rush Limbaugh’s call.  A local financial station, Money Radio, wanted to talk about 3D Printing. Renee Palacios and your truly were interviewed by John Barnabas, host  for “Happiness, Opportunity and Technology.”

You can listen to the full broadcast here:

You can always learn more about 3D Printing on our Rapid Prototyping Page  or contact us.

If you need someone to talk about 3D Printing to your organization or if you are in the media and need recognized experts who can explain the technology, contact us and we would be happy to work with you.

Build the “Right” Product

Successful product commercialization is achieved when the product development process is integrated with customer development and is executed by an experienced team and organized by an effective process. At PADT we have spent the last 20 years building our team, establishing our infrastructure, and honing our processes. One of the key processes that strongly affect the outcome of a product development effort is the process of establishing product/market requirements. The idealized product development process that we use is shown below and the establishment of requirements is shown as the first development activity box.

product-development-process

Establishing requirements insures that we develop the “Right” product. Building the “Right” product means working closely with clients to understand what the end customers want and are willing to pay for. It also means testing the market by building prototypes early and validating design choices with end customers.

At PADT we have found it very effective to get with customers from the very first meeting to establish these market and product requirements. Even if you are part of a large organization and do not work directly with external customers, we recommend that you adopt a methodology that captures and documents market and product requirements as early as possible, and that you evaluate your design against these requirements through the development process. 

 One way we do this is by asking questions about the product from many perspectives as illustrated by the wheel below. By looking at the product from each of these perspectives, we capture important requirements, avoid late stage product revision, and end up with the “Right” product.

product-development-questions

A question based approach is effective because it opens up everyone involved to looking beyond their initial assumption. The more traditional method of making a list of requirements, often results in requirements from the point of view of the person making the list. By questioning the customer, or proxy customer, from these different points of view, the team looks at things in new and different way and this captures more realistic and comprehensive requirements.

product-development-examples-PADTVisit our case studies page to see examples of how our approach has been used across a wide variety of industries.

The best way to understand the benefits of properly building the right process by establishing product/market requirements is to partner with PADT on your next product development project.

Throwback Thursday: 3D Printing on “Good Morning America” in 1989

3dprinting-1989

Note: This post is not displaying correctly, here is a link to the video:
http://youtu.be/NpRDuJ5YgoQ

Take a look at this science segment that Jeff Strain found on Stereolithography from 1989.  If you ignore the hair styles (Joan Lunden rocked that helmet hair) the report isn’t that much different from news coverage that 3D Printing is getting today. But the technology has sure progressed.

To add some additional perspective, according to the 2014 Wohlers Report, 104 systems were sold in 1989. 94 SLA machines from 3D Systems and 10 systems from now defunct Japanese SLA providers. 

The same report estimates that for 2013 9,823 commercial systems were sold by over 33 different suppliers.  This does not include the personal printer (low cost desktop) systems, which was estimated at over 72,000 units!.  That is 9,345% growth over 24 years for commercial systems.. 66,702 systems have been tracked as old.  

Take a look at the video. It is truly fascinating how the message still resonates and how predictions for replacing traditional manufacturing were maybe a bit optimistic.  But even in the early days, this report captured the promise of the technology. 

It has been an incredible ride, and it is not over yet.

Flownex and PADT Sponsor University of Houston’s Rankin Rollers Team

rankin-rollers-logoA group of enthusiastic students at the University of Houston are doing their part at solving that age old academia problem: not enough hand’s on experience.  They are designing and building a working steam turbine for the schools Thermodynamics lab so students can experiment with a Rankin cycle, learn how to take meaningful measurements, and study how to control a real thermodynamic system.

rankin-rollers-facebook

Look! Flownex and PADT on Social Media! Thanks for the plug guys.

After meeting a team member at the 2014 Houston ANSYS User conference, PADT saw a great opportunity to help the team by providing them with access to a full seat of Flownex SE so that they can create a virtual prototype of their steam turbine and the control system they are developing. 

The four team members have the following goals for their project:

    1. Create a fully automated system control
    2. Create system with rolling frame for ease of transport
    3. Create system with dimensions of 4x2x3.5 ft
    4. Deliver pre-made lab experiments
    5.  Produce an aesthetically pleasing product

    Flownex should be a great tool for them, allowing the team to simulate the thermodynamics and flow in the system as well as the system controls before committing to hardware. 

    You can learn more about the team on their Facebook page here, or on their website here

    We hope to share their models and what they have learned when their project is complete. If you are interested in using Flownex for your work or school project, contact PADT.

      IT Manager
      PADT, Inc.

    ——————-

    top-panel-deviceRecently PADT became a certified reseller for 3Dconnexion. Shortly following the agreement a sleek and elegant SpacePilot PRO landed on my desk. Immediately the ergonomic design, LCD display, and blue LED under the space ball appealed to the techie inside of me. As a new 3D mouse user I was a little skeptical about the effectiveness of this little machine, yet it quickly has gained my trust as an invaluable tool to any Designer or Engineer. On a daily basis it allows me to seamlessly transition from CAD to 3D printing software and then to Geomagic Scanning software, allowing dynamic control of my models, screen views, hotkeys and shortcuts.

    Outside of its consistency as an exceptional 3D modeling aid, the SpacePilot PRO also has a configurable home screen that allows quick navigation of email, calendar or tasks. This ensures that I can keep in touch with my team without having to ever leave my engineering programs, which is invaluable to my production on a daily basis. Whether you are a first time user who is looking to tryout a 3D Mouse for the first time or an experienced 3D mouse user who is looking to upgrade, you need to check out the SpacePilot Pro. I can’t imagine returning to producing CAD models or manipulating scan data without one. Combine the SpacePilot PRO cross-compatibility with its programmability and ease of use and you have a quality computer tool that applies to a wide range of users who are looking at new ways to increase productivity.

    Integrating ANSYS Fluent and Mechanical with Flownex

    Component boundaries generated in Flownex are useful in CFD simulation (inlet velocities, pressures, temperatures, mass flow). Generation of fluid and surface temperature distribution results from Flownex can also be useful in many FEA simulations. For this reason the latest release of Flownex SE was enhance to include several levels of integration with ANSYS.  

    ANF Import

    By simply clicking on an Import ANF icon on the Flownex Ribbon bar users can select the file that they want to import. The user will be requested to select whether the file must be imported as 3D Geometry which conserves the coordinates system or as an isometric drawing.

    The user can also select the type of component which should be imported in the Flownex library. Since the import only supports lines and line related items this will typically be a pipe component.

    Following a similar procedure, a DXF importer allows users to import files from AutoCAD.

    This rapid model construction gives Flownex users the ability to create and simulate networks quicker. With faster model construction, users can easily get to results and spend less time constructing models.

    p1

    ANSYS Flow Solver Coupling and Generic Interface

    The Flownex library was extended to include components for co-simulation with ANSYS Fluent and ANSYS Mechanical.
    p2

    These include a flow solver coupling checks, combined convergence and exchanges data on each iteration, and a generic coupling that can be used for cases when convergence between the two software programs is not necessary.

    The general procedure for both the Fluent and Mechanical co-simulation is the same:

    1. By identifying specified named selections, Flownex will replace values in a Fluent journal file or ds.dat file in the case of Mechanical.
    2. From Flownex, Fluent/Mechanical will then be run in batch mode
    3. The ANSYS results are then written into text files that are used inputs into Flownex.
    4. When applicable, specified convergence criteria will be checked and the procedure repeated if necessary.

    FDA Opening to Simulation Supported Verification and Validation for Medical Devices

    FDA-CDRH-Medical-Devices-SimulationBringing new medical device products to market requires verification and validation (V&V) of the product’s safety and efficacy. V&V is required by the FDA as part of their submission/approval process. The overall product development process is illustrated in the chart below and phases 4 and 5 show where verification is used to prove the device meets the design inputs (requirements) and where validation is used to prove the device’s efficacy. Historically, the V&V processes have required extensive and expensive testing. However, recently, the FDA’s Center for Devices and Radiological Health (CDRH) has issued a guidance document that helps companies uses computational modeling (e.g FEA and CFD) to support the medical device submission/approval process.

    FDA-Medical-Device-Design-Process-Verification-Validation

    Phases and Controls of Medical Device Development Process, Including Verification and Validation

     The document called, “Reporting of Computational Modeling Studies in Medical Device Submissions”, is a draft guidance document that was issued on January 17th, 2014. The guidance document specifically addresses the use of computation in the following areas for verification and/or validation:
    1. Computational Fluid Dynamics and Mass Transport
    2. Computation Solid Mechanics
    3. Computational Electromagnetics and Optics
    4. Computational Ultrasound
    5. Computational Heat Transfer

    The guidance specifically outlines what form reports need to take if a device developer is going to use simulation for V&V.  By following the guidance, a device sponsor can be assured that all the information required by the FDA is included. The FDA can also work with a consistent set of input from various applicants. 

    drug-delivery-1-large

    CFD Simulation of a Drug Delivery System. Used to Verify Uniform Distribution of Drug


    Computational Modeling & Simulation, or what we usually call simulation, has always been an ideal tool for reducing the cost of V&V by allowing virtual testing on the computer before physical testing. This reduces the number of iterations on physical testing and avoids the discovery of design problems during testing, which is usually late in the development process and when making changes is the most expensive. But in the past, you had to still conduct the physical testing. With these new guidelines, you may now be able to submit simulation results to reduce the amount of required testing.
    mm_model_stresses

    Simulation to Identify Stresses and Loads on Critical Components While Manipulating a Surgical Device

    Validation and verification using simulation has been part of the product development process in the aerospace industry for decades and has been very successful in increasing product performance and safety while reducing development costs.  It has proven to be a very effective tool, when applied properly.  Just as with physical testing, it is important that the virtual test be designed to verify and validate specific items in the design, and that the simulation makes the right assumptions and that the results are meaningful and accurate.

    PADT is somewhat unique because we have broad experience with product development, various types of computational modeling and simulation, and the process of submission/approval with the FDA. In addition, we are ISO 13485 certified. We can provide the testing that is needed for the V&V process and employ simulation to accelerate and support that testing to help our medical device customers get their products to market faster and with less testing cost.  We can also work with customers to help them understand the proper application of simulation in their product development process while operating within their quality system.

    Top 10 New Thermal Fluid Modeling Capabilities in Flownex 2014

    3D graphWe are pleased to announce the release of Flownex SE 2014.  This is a very exciting release for all of us involved in Flownex because it introduces a mix of advanced features and usability enhancements – we love better and easier.  We will be publishing more information about this release, as well as videos and webinars. While we set all of that up, we wanted to whet everyone’s appetite and give you a list of what we feel are the 10 most important enhancements.

    1. Rotating components, Swirl Boundary, and General Turbine and Compressor Models 
      A new library has been added which models rotating flow on a system level. Focusing on secondary flow and heat transfer in turbine engines, it includes all the components needed including compressors, turbines, seals, gaps, nozzles, and cavities. A complete library for Steam Turbine modeling was also added. 
    2. Importing and Geometries
      Users can read in 2D and 3D layout files in common formats and directly create Flownex models from the geometry. The model and results can then be visualized with the 3D geometry.
    3. GIS File Support
      When modeling systems that cover a large area, such as water or gas pipelines, the geographical data can be imported for display and to automatically include altitude into the model. 
    4. Connections to ANSYS Products
      Users can import 3D Pipe geometry as an ANF file, and connect to ANSYS Mechanical and ANSYS Fluent for co-simulation.
    5. Link to Mathcad
      Users can transfer parametric data to and from Mathcad worksheets
    6. Graphical Script Generation Tool
      Users can use Quick Script to create complex scripts to customize their processes or models without having to learn the full scripting language
    7. New Designer Tools to Quickly Model Common Systems.
      Designer tools atomically iterate on a user’s model to calculate unknown values for them. This release includes tools for calculating mass flow when only pressure is known at a boundary, automatically calculating steady state conditions in a two-phase tank, and a component designer that calculates input parameters for common components so that those components deliver the users requested mass flow.
    8. Five Additional Convection Models 
      Based on user input, five new models were added to the Dittus-Boelter correlation for calculating heat transfer coefficients: tube, shell-side single phase, shell-side horizontal tube condensation, ribbed wall channel, and channel with pedestals. 
    9. Exit Thrust Nozzle Added
      New model in subsonic and supersonic flow at the outlet of a flow network with gasses and superheated fluids
    10. Additional Enhancements:
      Support for miter bends in piping
      3D graphs
      Radiation supports multiple surface enclosures
      The range of methane two phase fluid was increased
