Stared 2018 with an Anet A8 I am currently running 6-10 FDM printers (depending on the projects I have running) and 1 MSLA (for detailed printer parts) printers.
I mostly print for fun, but recently started to print for fund raising and with that I was already able to have a few thousand € donated to Unicef... this is possibly the best cause I can throw my hobby and my 3D printers at...
I am also pretty active in a few printer related facebook communities, so just ping me if you have some questions, I will try my best to help
