Multi Jet Fusion: THAT's HP's promised 3D printer, not crazy 'leccy invention
Hang on Meg, didn't you tell us you'd have one by mid-2014?
A year and eight days ago, The Reg was in the room when HP CEO Meg Whitman promised the company would deliver a 3D printer that service providers could wield by the middle of 2014.
On Wednesday the company made a lie of that claim by revealing the Multi Jet Fusion printer it says won't go on sale until 2016.
“Multi Jet Fusion” looks to be the name of the printing process HP will use and the name of future printers. In this white paper [PDF], HP says the process works as follows:
“HP Multi Jet FusionTM technology starts by laying down a thin layer of material in the working area. Next, the carriage containing an HP Thermal Inkjet array passes from left-to-right, printing chemical agents across the full working area. The layering and energy processes are combined in a continuous pass of the second carriage from top-to-bottom. The process continues, layer-by-layer, until a complete part is formed.”
The company's also keen on “fusing agents” and “detailing agents”. The former cause inks to bond together, the latter will be used “ where the fusing action needs to be reduced or amplified.” Detailing agents will therefore help to determine whether a printed object is rough or smooth to the touch.
HP's Multi Jet Fusion 3D printer
HP's also talking up the chance to print materials in which some regions are stiff and others are elastic. Multicoloured objects will be possible, as will opacity, different textures and even thermal or electric conductivity.
The company even feels it may become possible to use ceramics or metals as “ink” in future models.
HP thinks that once its 3D printers come to market they'll be ten times speedier than current models, cheaper to operate and produce more detailed, more useful, objects.
“We expect early customers to have access to printed parts and initial HP Multi Jet Fusion systems in 2015,” HP writes in this FAQ [PDF] and says it is “working to ramp towards full availability in 2016”.
If the company can deliver in 2016, and can improve performance as promised, perhaps Whitman's over-enthusiastic promise can be excused. That the 2016 shipping date includes an “Availability is subject to change” caveat is not, however, encouraging. ®
