Out of curiosity, how long does it take to actually manufacture this stuff?
Assuming I have everything at hand, and don't have to wait for it....
It's about an hour to mount the chip and make sure it works. That includes time for repairs/rework, if needed.
It takes anywhere from 5 to 10 hours to print the plastic parts, depending on how the printer feels that day. That's right, 5 to 10 hours. The card holder takes 4+ hours alone. Screw-ups after an hour or two of printing are fairly common, too.
It takes about an hour to mount the chip/board in the plastic. That's a very touchy, sensitive process, because we have to be accurate to .01 mm, or the contacts don't line up.
It takes another hour or two for programming and testing. Each card gets written twice (once US, once JP) to make sure it works in either machine. Any failures here have to start over, and the board has to be un-mounted first. It does happen, mostly due to solder joints breaking because the board got flexed during mounting.
Some of these operations can be over-lapped. I can print plastic while mounting chips or complete boards. The limiting factor is how quick I can make the plastic parts - 3D printing is slow for larger objects, especially if you want them to look nice.
And it doesn't help that I actually am an old man, and can't stare at a small chip through a magnifier for too long without getting a headache
I can manage, on the average, about 1 card a day, given a weeks head start on the plastic stuff. Some days I get none done, some days two or three. It averages out to 1 a day, with final finishing and cleaning.
(And I don't work Thursday, Friday, or Sunday.)
He COULD charge $100 and most of us would still buy it.
Like Arkhan said, about half of the $60 price tag is to cover what we have -already- invested in materials. Feeding the printer alone is a huge chunk of that - especially when its being a pain and nothing wants to print right, or it fails on the next-to-last layer of the cd plate because a wire breaks. (The wires to the print head flex a lot, and are a frequent failure point)
All we are looking for from our sales is enought to recoup our investment, and pay for parts for the next run.
[For those who are really curious, we also have about another $3k invested in tools and sundries. (Price a good 3d printer. And remember, we got ours almost 2 years ago...) Almost none of the money is actual 'profit'. We are hoping the next run will help pay for a filament maker
