It occurs to me that someday next century we'll have "chemical" printers that can synthesize drugs on demand. Maybe the hospitals will get them first for cost and legal reasons but eventually just like 3d printers, there will be a hobbyist element.
Initially they might have chemical printers in hospital labs/pharmacies for emergency use.
And if you think the pharmaceutical companies won't pursue legal action faster and with more power than a gaming company...

It's illegal to make any firearm that is undetectable by a metal detector, and lawmakers are still working to make 3D printing weapons illegal.
For a home chemical factory like you're discussing, synthesizing drugs illegally would be by far the most popular use case. I'm sure someone would think of something legit to do with it, but it would be an edge case. They would never be allowed to get a foothold, legally.
