It's amazing to think that not long ago we marveled and scoffed at the prohibitive cost of 2D computer printing, going from simple monochrome printouts to highly detailed full color physical manifestations.

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…

From one of the embedded information slides:

Photoluminescent materials visible under UV light

They could print that on the surface but then everyone could see it rather easily.

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.

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.

How much do they cost? What kind of printing technology?

Someone below mentioned $130k, but is it the same product as this article states starts at $50k? https://www.techrepublic.com/article/hps-50k-3d-printer-show...

Powder + ink technology kind of a mix of polyjet and SLS?

Full color is nice but it always depends how colorization is handled. If you ever have to go into 3rd party apps to "paint" colors on, its not worth it. It needs to be able to handle coloring from the exported file ie color it in solidworks or creo or whatever.

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.

How much do they cost? What kind of printing technology?

The site claims:

> delivering quality output, up to 10 times faster[2] at half the cost[3]

And, reading the fine print:

> Based on internal testing and public data, HP Jet Fusion 3D average printing cost per part is half the average cost of comparable FDM & SLS printer solutions from $100,000 USD to $300,000 USD on market as of April, 2016. Cost analysis based on: standard solution configuration price, supplies price, and maintenance costs recommended by manufacturer. Cost criteria: printing 1 build chamber per day/5 days per week over 1 year of 30-gram parts at 10% packing density using HP 3D High Reusability PA 12 material, and the powder reusability ratio recommended by manufacturer. Based on internal testing and public data, HP Jet Fusion 3D 4210 Printing Solution average printing cost-per-part is 65% lower versus the average cost of comparable FDM and SLS printer solutions from $100,000 USD to $300,000 USD on market as of April, 2016 and is 50% lower versus the average cost of comparable SLS printer solutions for $300,000 USD to $450,000 USD. Cost analysis based on: standard solution configuration price, supplies price, and maintenance costs recommended by manufacturer. Cost criteria: printing 1.4 full build chambers of parts per day/5 days per week over 1 year of 30-gram parts at 10% packing density on fast print mode using HP 3D High Reusability PA 12 material, and the powder reusability ratio recommended by manufacturer.

So, sounds like we're talking something on the order of 50-150k per year or so if you're planning to use this frequently. Definitely not a consumer-focused solution.
