If it's anything like the rest of their printer line, it will be cheaper to just buy a new one than it will to refill the ink.

That has never been true, even for the cheapest consumer printers. The "starter" cartridges that printers come with only contain about 10% of the ink of a full cartridge.

I owned an HP Laser Printer recently (paid $250). The starter cartridge lasted me 4 years, and when I went to replace the cartridge ($50), it didn't work. The printer is now out of warranty, so I'll be buying a new printer.

How does this printer differ from other 3D printers on the market?

Full color. But as mentioned elsewhere in this thread, it's nothing new. Printer's with this functionality have been around for 15+ years. HP is like Apple, take an existing technology, sprinkle liberally with hip marketing, and boom! -- act like you invented it.

Their printing process is pretty new. Sure printers that can print in color have existed for a while now, but they weren't able to produce strong parts like this printer does. Other printers that produced similar strong parts also couldn't print as fast as this printer.

This is not correct.

We use HP jet fusion 3D printers to manufacture production parts at Jabil (see https://www.jabil.com/insights/blog-main/3d-printing-reality...) and MJF is quite different from other tech e.g. binder jetting, LOM, FDM, SLA, SLS, DMLS, EBM, CBAM, CLIP.

Differences include cost structures, speeds, material capabilities, resolution, etc.

Can you imagine how much they would charge for the "ink" on these things?

And because it's HP they're also doing other nasty stuff too. You know how most 2d printers put invisible tracking dots in their prints to prevent counterfeiting? Well HP's 3d printers are going to do the same for 'security', anti-counterfeiting, and DRM purposes. They can print whatever pattern of color they want inside the part, so that one can scratch off the surface layer and determine who ran off illegal copies of mickey mouse action figures and when.

To be fair they are weighing an unreleased solution in the most optimal configuration against nearly 2 year old data. For 100k shopping right now it would be interesting to get an apples to apples in the entire market because that is what people purchasing this will be looking at

We use HP jet fusion printers to manufacture end use parts (see https://www.jabil.com/insights/blog-main/3d-printing-reality...). They are impressive machines, and I'm excited to see the full color ones in action. Also, the MJF API is pretty well designed.

I bought a LaserJet CP1525nw for ~$250. The "starter" cartridges lasted me just over 4 years. Refills for it cost $340.

I bought a brand new LaserJet M452dn for $212.

That's essentially what happened to me. The cartridges got down to 1% and around the same time it started jamming. I bought a replacement Black cartridge and it continued to jam. I wasn't about to spend $200 on the color cartridges at that point so I bought a brand new printer instead.

Do you work for Jabil or are you just using that article as an example?

How do you find the mechanical properties of the parts? Do they vary print to print? Do they suffer from the same problems that cheaper 3D printed parts do - principally either very low strength across the layers (for FDM prints) or very soft materials (cured epoxy and most of the SLS prints I've dealt with).
