Lazy Man’s Solution to Feed the Cats

Friday, September 29th, 2017

3D printing solution makes it all possible – one step at a time

Imagine an automated way to feed your pets. Think of the time you’d save. Think of the hassles you’d eliminate. My kitties need to be feed twice daily, so I set out to make the process easier using both CAD and 3D printing.

For the manual method of food delivery to my cats, I have to measure out 1/3 cup of kitty kibbles with a  measuring scoop and then deliver the food into each respective dish.

I have two cats, so I have to do this for each bowl, twice a day.

It would be easier just to turn a handle, and in a matter of seconds, deliver the proper amount of food to each kitty at the same time – at least, that’s what I hoped.

Do You Print in Metal?

Friday, June 9th, 2017

It might be the most commonly asked question during my years at GoEngineer, and it was easily my least favorite question to answer. “Do you print in metal?”

It may surprise you to learn, but having to answer “no,” or more commonly “not yet,” isn’t actually why I disliked that particular question. Over time I’ve become adept at fielding the question in ways that kept their interest and channeled their excitement toward tangible options.

It wasn’t saying “no” that killed me, it was admitting that what they wanted didn’t yet exist.

Our users didn’t just want metal printing technology – they wanted metal printing that was as simple, affordable, safe, and easy to use as plastic printing. But it simply wasn’t available.

Desktop MetalAnd then along came Desktop Metal…

If you haven’t heard by now, Desktop Metal is a 3D printing startup based in Burlington, Ma. The company formed in 2015.  They have spent the last two years in quiet development of their hardware and software. And, they managed to draw about $97 million in funding from Google, BMW, Lowe’s, and Stratasys to name just a few of their high-profile investors.

Flow Simulation – How to Handle a Vortex Across a Pressure Boundary

Wednesday, April 19th, 2017

What is a “Vortex Across a Pressure Boundary?”

In Flow Simulation, a vortex is a region in the fluid domain which causes a swirl in a region where there is asymmetric drag in the flow field.  The vortex itself is an expected phenomenon which itself is not problematic.  When that vortex is allowed to generate across a theoretical boundary within a CFD analysis that can cause the results to deviate from reality in the immediate vicinity of the boundary or also cause the solver to fail to produce results at all.  For that reason, it is important to note where this is happening in an analysis and take steps to avoid it.

How can this be fixed?

The vortex itself is generating because of the local solid geometry near the pressure boundary of a CFD setup.  If the flow through the boundary is not symmetric, a low-pressure region can generate in front of the boundary allowing fluid to pass the wrong direction through the boundary as intended.  The fix for this is to “build out” the model geometry.  What does this mean? The solid model needs to have more real life geometry added to the setup so the flow field can be allowed to have the vortex and then transition into a unidirectional flow.

Solution 1: Add Geometry

An example of a vortex across a boundary would be directly from the first Flow Simulation tutorial in SOLIDWORKS.

(The tutorials can be found under ‘Help’, ‘SOLIDWORKS Simulation’, ‘Flow Simulation Online Tutorial’ once the Flow Simulation add-in is turned on).  The ball valve, as it is setup in the tutorial, has two lids that are positioned closely to the ball of the valve.  In situations where the ball valve is not set completely open the flow through the valve is forced to be asymmetric as it passes through the pressure outlet.

The asymmetric flow out the pressure boundary allows fluid to backflow through the theoretical pressure boundary and creates the vortex that is seen below. (more…)

Top New Features of SOLIDWORKS Electrical 2017

Tuesday, January 31st, 2017

SOLIDWORKS Electrical 2017 is here and we are super excited about some of the new features and enhancements it provides.  Although SOLIDWORKS Electrical is still a relatively young product to SOLIDWORKS; it’s users have been actively putting it through its paces and making suggestions to make it even better. This year we not only see some great enhancements, we got some great new capabilities.

1. 3D Layout – Use existing assembly

You can now use an existing SOLIDWORKS Assembly to insert your electrical components to route your wires, cables, and harnesses. They have also renamed the command, it’s still under the process tab but it’s now called “SOLIDWORKS Assembly”.  You can still have electrical create a new assembly or select an existing assembly from your local drive, network or Enterprise PDM.

2. Add data file shortcuts

When adding documents to your projects, such as a PDF, you can now link to the document. This is awesome because it allows you to store your reference material where you traditionally keep it instead of making copies within the project.

3. Replace attribute and renumbering documents

Both commands received huge improvements as well as new interfaces. Both make it easier to incorporate changes faster and more accurately.

Recorded Webinars – A Tool for Personal & Professional Development

It’s hard to believe 2016 has come and gone.  Were you successful in completing your 2016 resolutions?  I found personally, that setting obtainable goals worked best and were much more fulfilling in hindsight. Here are 3 rules I live by:

  1. Commit to a Resolution that is obtainable – Start Small.
  2. Tell everyone close to me for accountability purposes – Talk about it.
  3. Don’t quit when steps aren’t achieved as quickly as intended – Never Give up!

So, now that we’ve outlined how to set a resolution and stick to it, let the learning begin! Below you will find a short list of Top GoEngineer webinars of 2016.

Sit back, Grab a cup of coffee or tea, and hit play!

For this first video, you will learn about New and Enhanced Features of SOLIDWORKS 2017 according to Sean Stone, Applications Engineer.  Here Sean shares some of his favorites from this years’ launch events as well as some buried in the What’s New document.

Visuals are important to the design process, stories, social media and more. They are dominating Pinterest, that’s for sure.  In this webinar, you will learn tips and tricks to the Visualize Interface and ideas for new graphical content you can bring to your company.

5 Myths about your SOLIDWORKS Network License Manager

Tuesday, November 29th, 2016

solidworks network licenseLet’s talk about your SOLIDWORKS network license and debunk those myths with facts. Which one of these 5 are you guilty of believing?

You accidentally received extra licenses (yassss!).

Not true.  Only once in 5 years have I seen SOLIDWORKS write an incorrect license file.  The way licenses are listed in the SNL can be misleading.  Suppose you have a network license containing 1 Professional License and 1 Standard license.  The SNL will show 1 Professional License and 2 Standard Licenses. Why?  Because when you are pulling a Professional license, the license manager is releasing a Standard license and the Professional ADD-INS.  So really the license manager listing should read “Professional ADDINS”, rather than “Professional”.  You cannot pull a Professional or Premium license without pulling a Standard license.

You don’t have the ability to use SOLIDWORKS on your home computer.

Custom Motorcycle Windscreen Brackets with SOLIDWORKS & Stratasys 3D Print Technology

Motorcycle Riding – 2010 KTM SMT

For me, riding my motorcycle is having the freedom of the open road and traveling with the wind in my hair!  Sounds great, right?  Well, after any extended period of riding in the weather elements; physical and mental fatigue takes over, leaving the operation of a motorcycle quite dangerous.

On my quest to create comfort and extend my riding to a long haul, I decided to improve the stock windshield (or windscreen) of my KTM SM-T. This is where aftermarket parts, SOLIDWORKS and 3D printing technology takes over.

Motorcycle Windscreen: Stock vs Touring

Take a look at the stock windscreen below. It looks ergonomically ‘sporty’ but doesn’t provide much protection from the weather elements.

morotcycle-comfortIn comparison, you will see a touring windscreen below. This version is significantly taller but still does not provide the necessary protection from the weather elements.

Plastic Part Design – A Career

Injection-molded plastic part design is a  job thet tends to fall into your lap.  You have zero qualifications, and yet, you are supposed to do it perfectly while blindfolded. It’s difficult to lunge forward with confidence when you are building on a poor foundation.

The result is that you proceed with the project with a “learn-as-you-go” approach. Even so, there’s still opportunity to avoid common mistakes, make smart decisions, and release a smart, young, well-prepared injection-molded part into the universe, ready to make a big impact and change the world.

Read on to learn How to Successfully Design Plastic Parts.
