The new Stratasys J750 is part of the company's series of Objet Connex multi-color, multi-material 3D printers. It allows customers to choose from more than 360,000 different color shades (thanks to Stratasys' work with Adobe) plus multiple material properties — ranging from rigid to flexible and opaque to transparent, according to the company. The J750 has a build envelope comparable to the Stratasys Objet Connex3 500 3D printer, but twice the material capacity, four times the number of jets, twice the speed and smaller layer thicknesses.

"We can place drops in mixtures of colors that are consistent across the entire part," said Roger Kelesoglu, Global Sales Enablement, Stratasys, at a launch event at OtterBox's headquarters. "This is a really big thing for people who value color — that we can accurately address the color gamut that we state in all directions in X, Y and Z from print to print on the same machine, or from machine to machine. The color consistency in unmatched."
The Stratasys J750 features a six-material capacity to help minimize downtime associated with material changeovers. The newly designed print heads — which are included (up to eight per year) in the J750's three-year warranty that comes standard — means simulated production plastics, like Digital ABS, can be 3D printed in half the time of other Stratasys PolyJet systems, according to the company.
The ability to dial-in specific colors, materials and finishes can help companies skip the post-processing step required to make many types of parts look realistic for use by focus groups, or by executives or clients making final part design decisions.
"With the introduction of the J750, we are harnessing more than 25 years of experience to set a new historical milestone in 3D printing — reaffirming our commitment to keeping customers always on the cutting edge of innovation," said Josh Claman, chief business officer, Stratasys, via a press release. "With its one-stop realism, the J750 is quite simply a game changer. By combining full color with multiple materials and a streamlined workflow, it recalibrates the impact of 3D printing in the product development cycle. Informed design decisions can be made immediately after the concepting stage. The time saved by eliminating the painting and assembly process can lead to faster product delivery times. The J750 is a multi-purpose system that can also produce production tools, manufacturing moulds, teaching aids, and other models — truly raising the bar in 3D printing versatility."
Stratasys has also released its new PolyJet Studio software, showing that its acquisition of GrabCAD is bearing fruit. The software's new interface allows users to choose materials, optimize the build and manage print queues. Assignment of colors, transparencies and rigidity is eased via familiar design controls, according to the company. Color textures can be loaded fully intact via VRML (Virtual Reality Modeling Language) files imported from CAD tools.
At the J750 launch event, Claman said GrabCAD has become Stratasys' software development group. "We bought GrabCAD because we realized software is going to be a key element in the adoption of 3D printing," he said. "Simplifying the workflow, automating more tasks, developing standard platforms that work maybe across all printers — that's where most technology markets head, that's where we think this one is going."
Claman also said he sees Stratasys entering into a "third phase" after the merger with Objet, then the acquisitions of MakerBot, Solidscape, SolidConcepts and Harvest Technolgies. In the third phase he says the company will transition toward solutions-focused business to solve specific customers' problems in vertical markets and will shift its technology development roadmap toward manufacturing.
Customers can order the Stratasys J750 immediately. Delivery times may vary according to region, according to the company. The Stratasys J750 is being showcased at AMUG 2016 this week in the Demo Suite.
