Funny thing is that said HP still exist.

What people are complaining about is the bottom of the barrel consumer products hawked out of very storefront the world over.

I have seen similar sentiments aimed towards Acer, yet i have seen Acer business market laptops survive for ages.

Basically companies like HP and Acer have multiple product ranges with different QA protocols and different margins. Yet people keep buying the cheapest consumer offerings and expect something mil-spec.

Earlier quoted context omitted.

I have the same intuition, but was recently surprised about their laptops: Even though (or maybe because) they look like from last century they have pretty decent hardware connectivity (USB, video, ethernet etc.) and good linux support as well. It's boring but functional, like you'd expect from a business-oriented machine.

I got a spectre and was extremely disappointed. This is after getting the signature edition Windows so it would be bloatfree. The touchpad is really bad.

Perhaps there is a reason why they offer a mouse with the same design language?

Following some links around i get the impression that this is using laser sintering.

It's a powder bed, like laser sintering, but the melt energy comes from IR light sources. The parts of the bed that were printed on melt under the lights, the other parts stay powdery and can be recycled.

Heh, i knew i should have left the laser part out.

Anyways, would be interesting to see this way of doing 3d printing find its way to the hobbyist market at some point.

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.

A 3D printed chain link that can lift a car. That's a pretty strong 3D part...

Maybe my understanding of "Reinvent the wheel" is wrong, but I always took it as "spend time inventing something that already exists", basically wasting your time. Didn't think it was a positive term you want to put on your landing page.

I believe the phrase ``reinventing the wheel'' emphasizes the difficulty of optimizing something that is fundamental, widely used, and has been tackled by armies of engineers.

There are companies that refuse to dilute their brand or sully their image:

- BMW, Lexus

- Tiffany's

- Rolex

Tech companies just think that they are immune to the market forces that keep other high end brands from skimming off the lower rungs (or at least doing it with their marquee brand).

The examples are just the first ones from different markets that came to mind.

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).

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.

Interesting to see HP jumping in here. They certainly have the positioning/deposit/chemistry expertise to make this work.

I would love to be able to print things on one at the local copy/printing center, but I'm wondering if they have moved enough down into the price point to displace what the current SLA shops offer.

And while I've posted things to Thingaverse there is an interesting opportunity for a curated source of soft 'things' that you could order from a local service bureau. Shapeways is nice but it doesn't seem quite there yet.
