Last week, the company unveiled its Multi Jet Fusion 3D printer, saying when it ships in 2016 it will enable production of parts with a technology traditionally reserved for rapid prototyping.
The new industrial 3D printer – a little larger than a washing machine – is 10 times faster and 50% less expensive than current systems on the market, HP said.
The first version of the printer uses thermoplastics and multiple colours, but HP plans on expanding materials to suit a variety of production manufacturing. The machine is capable of producing high-precision parts, HP said.
“That detail is not possible in a desktop device,” said Steve Nigro, Senior Vice President, Inkjet and Graphics Solutions Businesses, HP. “You can do some simple applications [with a desktop 3D printer].”
HP plans to ship the Multi Jet Fusion 3D printer to beta customers early next year and begin mass production and sales in 2016, Nigro said.
HP has not announced prices, but Nigro said it would be competitively priced against other industrial 3D printers on the market today that run between $100,000 and $1 million.
HPs 3D printing technology combines the attributes of binder jet printing, where a liquid bonding agent is selectively deposited to join the powder materials, and sintering technology, where layer upon layer of powder material is melted and fused together with heat.
The printer works by first depositing powder (about 100 microns thick or the thickness of a standard sheet of paper) onto a print bed using a print bar that looks like a scanning bar on a typical 2D printer. The print bar has 30,000 nozzles spraying 350 million fusing agent droplets a second in specific patterns as it moves back and forth across a print platform.
A detailing fusing agent is sprayed around the edges of a printed object, giving it “sharp” details.
Nigro said HP will be targeting enterprise and service provider “central production environments.” He doesn’t see the machine being used for mass production, but instead for one-offs or limited production runs.
Using a production gear as an example, Nigro said 3D extrusion techniques – where layer upon layer of thermoplastic nylon is laid down – can take up to 83 hours to create the part. Laser sintering, where a laser fuses layers of powder together, can take 30 hours.
“With Multi Jet Fusion, it takes three hours,” he said.
“For us, to change industries, you need to replace what was analogue-produced parts with digital,” Nigro continued. “That’s a high hurdle. To get that from a desktop system, we don’t see that as possible.”
Comparing it to what HD did with 2D printers, scaling them in size depending on the need, Nigro sees many different versions of the Multi Jet Fusion printer – some that HP will make itself, and others that it will partner to create.
HP is creating an “open” collaboration program for developers who want to work with HP to create specialty applications for the 3D printer.
“There’s only so much HP can do on its own,” Nigro said. “We view this as a horizontal 3D printing technology…in the sense that it can be configured in many configurations to serve many markets. We can scale it for more industrial applications…[and] you can imagine us scaling it down and going into workgroup applications. Those are all possibilities.”
With CAD software to design the parts and a Multi Jet Fusion printer to produce them relatively quickly, manufacturers could use 3D printing for large test runs, Nigro said –enough to beta test parts before modifying them for full production runs. Using a 3D printer would save company development and production costs.
“Ultimately, it will change the workflow of manufacturing,” Nigro said. “It will allow us to create an agile manufacturing world.”
