From my experience after we got a
Fortus 400mc (about $100k) in at work, "professional" products aren't really any better. It's so bad that Fortus flies in a tech for all new system startups.
When we were setting it up, first the machine decides to slam the print head into the side of the machine during XY zeroing. After reseating some cards in the embedded Linux PC, it started working. However a few days later, it stopped again. After rebooting it a few times, it would no longer boot. They instructed us to restore the software using a supplied USB stick, but no luck, "Installation aborted" is reported on the screen and it reboots.
I connected a monitor to the Linux box, and actually got some useful feedback! The disk was corrupted and needed a FSCK run. But of course, I don't have the root password so I couldn't do anything. Tried the USB a few more times, and it randomly decided to work and restored the default image. That got the Linux box running again, but the Z axis auto zero now doesn't work, and the Y axis won't move when trying to print. We're currently waiting for a new Linux box to be shipped in from the manufacturer. If that doesn't solve it, the tech is coming back.
The manufacturer is also getting greedy like inkjet printer manufacturers, the 1.5kg material cartridges sell for $480 each for ABS and soluble support material, when the actual material cost is probably about 10% of that. The cartridges apparently contain about 20-30% extra material, but the onboard chip cuts you off at the stated capacity, and prevents you from refilling them. Looking at some blog posts, it's apparently not too hard to hack the security and refill them with your own material.
Similar to Agilent with licensed memory "upgrades", they charge $20k to enable use of the full build envelope, it's just a license key you install. Same for adding support for different materials, $15k each, and then you just need to change the $100 extruder tip. I can somewhat understand licensing the material support, as it probably takes a lot of effort to determine the exact head movements and extruder speeds required for each, but the build envelope is just like scope RAM, you already paid for the extra silicon, or in this case steel!
