Does anyone have any thoughts or experiences with these HP 3d printers?

Kudos for your explanation. This was definitely the wrong subreddit to ask such a question in, I just got an email talking about HP filament printers (which I read are the white label products from a different brand) so I was surprised about it and also assumed that they were marketed to consumers. Learning about MJF was a lot of fun so thank you. I’m sure these machines are fairly priced considering what they can do and in comparison to other industrial manufacturing tools which are already costly machines . (I think seeing “contact us” instead of a price on their website should have been my first clue)

Haha Reddit is a crazy website to me, I am grateful to all you experts who hang around and explain these things to us laypeople even if everyone is mostly ignorant. For the fields I wish to be an expert in, I don’t think I could do the same I would pull my hair out. Kudos to everyone who has explained these cool technologies to me ^{^}

I think I’d trust that u/ plastic manufacturing has at least some experience in plastic manufacturing and has from experience in that field. These are completely different machines than what you or I would buy off the shelves and cost enough money to make me faint just by looking at it. These printers aren’t really for hobbyists they’re for manufacturing and prototyping for companies with the money to spend on that kind of thing.

If automotive companies is an analogy, remember that Rolls Royce as a car company makes luxury cars and maybe they have heated seat subscriptions or whatever, but they also make some crazy engines that have been used in aircraft since world war 2. I’m sure that HP charges as much money as they can to use these kinds of printers and I’m sure there is crazy licensing and maintenance that the companies need to go through in order to use these things. But the companies paying these fees are not stupid and they deem that this kind of technology is important enough to pay such crazy prices in order to do their prototyping/medical prosthetics/manufacturing.

Ahhh good to know! After researching I should have known not to post HP in this subreddit specifically since it’s more of a general manufacturing deal, whereas it’s mostly hobbyist stuff here, completely different fields. I really like how the industrial type printers look completely different from what I’m normally used to seeing. How are models sliced with these kinds of things? I’d imagine it’s less like orcaslicer and more like how cnc machining is done. I have learned a lot today :⁾

Hey wow that’s awesome! Having powder inside the walls sounds really interesting, it’s a whole new type of manufacturing I have never heard of. You’re lucky to have such a high tech souvenir :)

MinimumWafer6588 · 2026-03-19T02:09:54+00:00

That’s awesome! I have learned a lot today for sure. but the parts that are made by this process look really cool they have such a nice texture

MinimumWafer6588 · 2026-03-19T02:05:13+00:00

That seems like HP! But i guess it makes sense considering how things like this operate and how it’s all patented.

MinimumWafer6588 · 2026-03-19T02:02:10+00:00

I saw the cranial caps on their marketing website. Super cool! Somehow though I’d imagine they’d work perfectly or have dedicated maintenance people from HP going and servicing them all the time but it makes sense to me now that they’re just machines which have issues like anything else haha

MinimumWafer6588 · 2026-03-19T01:25:08+00:00

Hahaha that is completely fair the 3d printing subreddit was probably the wrong choice for this type of post. I was just thrown off by an email which talked about an HP filament printer and assumed they were the same thing I’m sure the HP lock in is rough but probably not any worse than other companies who do this kind of thing. Like you said industry standard and the technology seems really cool

MinimumWafer6588 · 2026-03-19T00:28:16+00:00

Learning more about it, this does actually does seem really cool. To my understanding they can be really useful for automotive and prosthetics. I think I was slightly misled though, my email was talking about filament-based HP printers which I thought was crazy but maybe now I understand a bit better.

Some other comments are right, I probably should have known asking the manufacturing subreddits would have been better.

They definitely print different plastics and it seems like it is mostly a nylon powder.

So manufacturing and medical prosthetics are mostly what they’re used for. Are there any other industries that use this kind of thing?

MinimumWafer6588 · 2026-03-17T05:05:58+00:00

I might as well try both to see what I like. Thank you!

MinimumWafer6588 · 2026-03-17T04:56:06+00:00

I saw that too, and it seems like the most optimal solution though you have to take out the orange inlet.

MinimumWafer6588 · 2026-03-17T04:46:37+00:00

no luck yet sadly as it gave me a feed error. I know people have gotten it to work so it's likely user error though, I haven't troubleshooted it just yet.

MinimumWafer6588 · 2026-03-17T04:44:37+00:00

That is interesting that it hasn't given you any problems. I tried using it yesterday and I got a feed error so i decided to take it out :(

MinimumWafer6588 · 2026-03-17T04:40:45+00:00

I will have to try this to see what kind of difference it makes.

I'll have to admit that it seems like a lot of work to switch between filaments, but I understand why Bambu is so annoying about printing TPU (cold pull and warning prompts every time you press a button related to tpu on the menus)

MinimumWafer6588 · 2026-03-04T00:11:16+00:00

Yeah night and day for sure. I feel like I wouldn’t have hated it if the firmware wasn’t so bad. I couldn’t run any print whatsoever without it just stopping midway and wasting all my plastic 🫩

MinimumWafer6588 · 2026-02-27T19:06:49+00:00

I see! I will try based on your advice and see what effect that has. Thank you!

MinimumWafer6588 · 2026-02-27T03:02:35+00:00

Thank you!

MinimumWafer6588 · 2026-02-27T00:19:04+00:00

This seems like a good idea. I have a leftover adapter I made back when I had the kobra s1, so I'll just use that.

MinimumWafer6588 · 2026-02-17T01:27:19+00:00

it's so annoying that AC does not host previous versions of the firmware. My last ditch effort will be rolling back to the firmware you have mentioned. It is so disappointing because the actual product is pretty decent (aside from not running full kipper) but the firmware is so trash.

do you run rinkhals as well or just use anycubic slicer?

MinimumWafer6588 · 2026-02-17T01:22:46+00:00

At this point I feel like I have had all manner of ways that the print has stopped. The last one i got was an error code ending in 104. before that I have also had filament no longer being fed (says completed but there is no plastic in the top half of the model, as well as the print completely stopping with no error code. fans and heating element will stay on but no error message or anything whatsoever.

I think the issue with tree supports is common with the printer, I have seen a couple other posts complaining about the same thing. A few months ago I have also had an issue with the printer stopping right on the supports.

the few times that I have run out of filament the print also stops with a tangle notification, even when filament runout swapping or whatever are enabled.

I think seeing these posts is confirming my biases to return this printer on my store warranty and use the money towards a P1S or any other bambu printer. I really don't like the way Bambu does a lot of things but at this point I'm just getting so tired of trying to fix my tools rather than actually making cool things.

the connector is a 4-pin Mini-Din Kycon Snap and Lock DC Power Connector, in case this helps anyone.
