I did something similar
Back in 1993 we got a "Cubital" rapid prototyping machine, at the Alberta Research Council, which cost over $1 million and was approximately the size of a Buick (think of a Buick that got compressed in a wrecker), and which came all the way from Israel. I was an intern in the "mantech" manufacturing technologies group which acquired this beast, so I was tasked with marketing this thing all across North America. Being a BBS guy, and this being pre-internet era, my idea was to get a Fax Modem on the PC and hit all the aerospace manufacturers, defense, automotive, and anybody else I could think of. NASA, etc. So I created a dialing list of about 500 fax phone numbers and prepared this page on Aldus Pagemaker on the Mac describing this new rapid prototype, "additive manufacturing" technology that we got up in Alberta, and hit "send". Of course, long distance is cheaper overnight so that's when the autodialer went off. Well, a couple weeks later we got the phone bill, and my boss was surprised how much repeatedly failing fax transmissions could rack up that quickly. I forget the exact number, but it was a couple thousand at least. Anyway so much for that.
(So anyway, this technology morphed from "rapid prototyping" to "3d printing" which is practically ubiquitous today. Being a government initiative it wasn't meant to be a "profitable" venture, or to compete with the private sector, but let's say the technology matured very very rapidly and the Cubital machine became obsolete very quickly, and kinda worthless very quickly. But it made very, very, very good parts, and you take guys like GM and NASA and they generally have their own $1 million budget if they thought it was important enough. I left to go finish my degree, Mantech got dissolved, my boss was summarily fired, and even ARC got recycled into Alberta Innovates today. Fun time! The only other time I heard of ridiculous phone bills was my buddy running a Fido Net node, again pre-internet, which would ferry email between cities. I think his monthly long distance bill was like $80 or something which supposedly would be paid by the Fido Net enthusiasts, I never heard how well that worked.)
