We use HP jet fusion printers to manufacture end use parts (see https://www.jabil.com/insights/blog-main/3d-printing-reality-printing-the-printer.html 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.

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).

  Not affiliated with Nabil or HP, but I have done a fair bit of research on the tech for this printer line. It is pretty fundamentally different to FDM or SLA. Closest to SLS, but still not really the same. Mechanically it should be very similar to SLS, but uses a deposition style more like SLA. So in theory it should besomewhere in between. The material I've read and demo material prints I've seen so far back that up. Should be good for small run cosmetic and functional demo prototypes, but you want see it used for mechanical short run production parts.

    MJF is used for production parts today.

  I was recently at HP labs and got to see the mono color printers in action. The process is very consistent, and they told me that the parts are very uniform. Given my own observation of a bunch of finished parts and the active process, it produces very consistent results. The pieces were pretty damn durable. (I couldn't break them by hand). They used either Nylon or Glass Fiber reinforced Nylon.

    BTW, the printer I saw had made ~70% of itself. So, the parts coming out of it were good enough to produce many of the parts it requires to operate.

  Currently work at Jabil building software for managing 3DP at global scale. Can't get into the details on evaluating part quality other than to say that I personally think MJF parts are awesome - completely different thing than FDM. Just considering look and feel, MJF part density and texture create the perception of quality.

ballpark cost?
