These are nice and I have MK3 as well. However, I am doing most of my prints on HP MJF these days. It’s so much better and the cost is very reasonable. FDMs are good toys that require love. A lot of it (which can be good and bad).

Are you referring to a $250,000 HP MJF printer, or is there something else?

I too would rather print on a hundred thousand dollar plus printer than a one thousand dollar one. I still use Prusas for my robotics work because I can print multiple parts in a work day and iterate quickly. Either you are ordering parts and have to wait days for them to arrive, or your budget is very different from mine. I did work at Google X and have a few MJF parts still from their in house machine. They are nice, but they are in a totally different league. My MJF benchy sits next to my Prusa MK3s at home.

>FDMs are good toys that require love. A lot of it (which can be good and bad). Eh, that's not really the case any more. If you spend a sensible amount of money on a properly built machine, it's pretty close to fire-and-forget. Features like automatic bed levelling, PEI build plates, runout sensors, reliable direct-drive extruders and spaghetti detection have removed most of the annoyances in FDM printing. I was a long-time FDM sceptic, but the technology has reached a level of maturity where it fills a useful niche. FDM machines are an increasingly common sight in machine shops, tool rooms and MRO facilities; in an environment that's staffed by people who are familiar with CAD/CAM, they can produce a useful subset of parts with an almost trivial level of cost and effort. Unless your employer is extremely generous, you probably don't have an MJF or SLS machine that's just sitting idle in case you need a widget in a hurry. FDM thrives in the niche traditionally occupied by hand tools and that sloppy old Bridgeport - workholding one-offs, kludgy parts to keep a machine running until the field tech arrives, parts you only need in order to make other parts. An FDM printer is the mechanical embodiment of the phrase "close enough for government work".
