All depends what your use case is ..
When hp teased thier kit they claimed they would be faster than anything that was available... voxel technology they said .. and when they mean customer they mean paying guinea pig...(oh the stories i could tell about thier large format stuff).
Maybe they thought they could just rent out thier IP..and for all i know they might of ..but most of the really interesting stuff is coming from engineers and having some real world problem , not a blanket far fetched kool aid view of "every home will have one you pay a small sum for a file and hey presto life size robot."
When you look at some of the real benifits of am in general and some solutions the smart companys have achieved,there's no way hp could compete.
It's hard theres the material science, the machinery, the software>>by comparision ink has been around for centuries paper even longer and printers have been developing since the 1500's
Icon printed a rocket engine in a week and changed the design spec 3 days in to the print ...undergoing nasa certification 3months ago
Metalio built a printer inside a Hass milling machine..edm'd a portion of a cracked helicopter blade out and then printed in the repair ...certified airworthy about a week later
My absolute favourite Mazak have a 6 axis lathe that will swop it's tool head to a metal print head seemlessly, print what ever dodad then swop back to a cutting tool and mill turn or finish dodad...
Most grades of stainless alloys have now been certified as have most aluminium alloys, titianium, inconel as have most engineering platstics, military and aviation.
Hp'$ kit uses deskjet technology to spray a binder to (mostly plastic) which is ok if you want to print key rings and marketing crap ... but you could do that with any decent desktop 3d rig (crealityA6 with tasty mods and a smoothie board for shenanigans)
Desktop metal and others also use a binder but the part then gets aneiled in an oven,,, the part will shrink and thus has to printed 20% bigger, hp goning to start selling ovens?...
The OH's cannon died a few months back so the perfectly usable 12 year old deskjet came out, the replacement inks came to a £ more than a new desktop printer filled with all the DRM and bloat you could ask for... i admit i hesitated but bought the inks and had to screw around to get the open source driver (thiers) to work... as they deamed it obsolete.. funny how similar vintage machines drivers worked, scans as well.
Point is a b2b ink reseller was never ever going to make a splash in this arena... it"s moving way to fast in so many directions that avarice is a limitation...what was thier intended use what problem were they trying to solve what inovation could they bring to the greater am industry?? That they made half of what they did almost seems impresive to me ... considering in the time that they anouced they were going 3d,other companys have developed printers on mobile cranes and can print a medium size house in a few days, and no propritey 'voxel" ip in any of it.
Apologies for the length of this post but this shits important to me and it would be remis of me if i didn't give it the fuller perspective.
