Not for me, your mileage may differ. I retired my vinyl years ago, and I'm a firm believer that the CD is king and that digital music reproduction gets a bad reputation because of squished down MP3s. Tape has way too much hiss, except when used with DBX or other companding. That said, I still love my old Fender tube amp, so I do believe in some retro gear.
Nevertheless, it is unfortunate to say, since 3D printing is based on digital signals, the LPs created are digital copies. In other words, less quality than they could be. In the case of preservation, It is good enough. Now it just seems silly to print an LP. I suppose it's a good option for those hipsters out there. It's all about image these days.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
