My MK4 is definitely a lot quicker than the MK3s we use at my lab. It’s certainly not the fastest printer on the market, but I’ve been very happy with it so far.

And what’s nice about it (from your perspective), you can very easily disable the WiFi permanently on it, given that the WiFi card is externally mounted on the board chassis and held in place with like one screw. I installed mine and finally was able to set up the PrusaConnect feature on it. I’m usually not a fan of cloud services but I trust Prusa more than I trust Bambu.

Regardless, if you can get your job site to fork the cash over for one, I have nothing but great things to say about the MK4. The nextruder and its LoveBoard will make maintenance on the hot end worlds easier and more convenient than the MK3 (which wasn’t that bad to start with).
