Unfortunately for everyone involved (except those commercial companies), Nancy, you are not alone there!

I tend to think more in terms of hardware, too, Nancy, although open source really does mean source code. Controller cards--and for that matter commercial execution of IEEE standards--do seem to live in their own world, though, don't they?

The Open Source Hardware Association. http://www.oshwa.org/

 

After reading a bit about their efforts to standardize the open hardware license, it seems like it will not foster the same level of sharing and innovation. It seems like a copy and sell situation. As in the makerbot case.  

Saying open-anything is a great way to promote your product to a certain crowd. Thinking, most will not copy their designs due to the lack of ability. Or so one major company I interviewed said.

Thanks for elaborating, Ann - that was pretty much what I was trying to communicate. I was approaching it more from a hardware view. For example: the IEEE-488/GPIB standard. With that you should be able to get any IEEE compatible instrumernt to talk with an IEEE controller card because of the standard. However, some megacompanies who shall remain nameless (Grrrrrr) have advocated a proprietary approach to their controller cards and software so that makes everything not quite standard and necessitates either extra drivers (for purchase of course) or using only their stuff. You could use different products but sometimes the customer insists on a particular company which makes the test engineer's task much more difficult.

Cabe, the technologies that are usually called "3D printing"--SLS, SLA and FDM--actually are patented. But the patents have been expiring over the last couple of years (SLA, FDM), and are continuing to expire this year (SLS), which is why there's been an explosion in low-cost SLA and filament fusion printers over the last 12-18 months or so.

Nancy, open platform usually means based on open standards, such as software with a fully documented, published API, or hardware based on a non-proprietary OS and/or chips. Open source usually refers to software and means you get access to the source code and can modify it.
Here's an example from ancient tech history: open platform is what happened when Cisco lost its proprietary death grip on the router market in the 1990s because others started building routers with Intel chips and the Microsoft OS, vs Cisco's own proprietary ASICs running their proprietary OS.

Open-source hardware... Not quite the happy thing open source software is right now.

The definition and reules are still in flux, but it will be there eventually. I was considering making a design I had open, but not after the makerbot copy cat hit it big on kickstarter.

 

 

As for the cookie cutter, I would buy one. How else would I make one that is so pro and exact?

@a.saji - I really think someone will pay for a design because it happens everyday.  We buy things that we can make ourselves because someone else does it more creatively or with more skill or more convenience.

Sandwiches, cupcakes, t-shirts...I'd bet that everyone on this site could do that themselves.

I disagree. Most people pay other not because they can't but because they can simply afford it. Until recently there was an application in the App Store which was named "I am rich". It cost $999 but couldn't do anything at all.

Virtual Reality (VR) headsets are getting ready to explode onto the market and it appears all the heavy tech companies are trying to out-develop one another with better features than their competition. Fledgling start-up Vrvana has joined the fray.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.
solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
XYZ, Rabbit, and Disney innovate on the 3d printer in different ways -- from price point to using materials such as yarn.
