Excellent post Bill. I have been involved with AM for quite some time and the greatest benefit I see in my daily work is "proof of concept". The time spent in providing a DG (design guidance) model is remarkably short compared to traditional methods; i.e. machining, casting, forming, etc. One area gaining additional "respect" is the production of jigs and fixtures to hold components during assembly operations. This is proving to be equally time-saving and allows us to do a great deal of additional "what-if" at minimal expense.
Thanks for this informative report from the front lines about the fact that 3D printing and AM have gone way beyond prototyping. We've heard a lot about medical and dental apps, but it's important to know the extent that fixtures and tooling, as well as automotive, are being affected by AM for production parts. I also think the stats on injection molding costs and time are valuable. There seems to be a perception that 3D printing is slow, but it depends on what you're making with it. Compared to traditional methods for some end-use parts, it's really fast.
Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
