Purple Platypus - Precision 3D Printers & Service

When Objet introduced its patented PolyJet™ technology in early 2000, it gave companies of any size the ability to produce complex, high-quality models quickly for the first time. With non-contact resin handling and easy water-jet removal of support material, PolyJet is the ideal 3D printing technology for office environments.

Objet’s PolyJet inkjet technology works by jetting photopolymer materials in ultra-thin layers (16µ) onto a build tray, layer by layer, until the part is completed. Objet Studio™ software manages the process.

Each photopolymer layer is cured by UV light immediately after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing. The gel-like support material, designed to support complicated geometries, is easily removed by hand and water jetting.

• High quality – market-leading resolution of 16µ ensures smooth, accurate and highly detailed parts and models
• Highly accurate – precise jetting and build material properties enables fine details and thin walls (600µ or less depending on geometry and materials)
• Clean – suitable for an office environment, with non-touch resin loading/unloading, easy support removal, and simple replacement of jetting heads
• Fast – rapid PolyJet Technology process, due to high-speed raster build at full width, simultaneous building of multiple items, and no post-curing
• Versatile – a wide variety of FullCure materials enables parts with different geometries, mechanical properties, and colors — use of the same support material for all model types makes switching materials easy

PolyJet Matrix™ Technology, a new direction in 3D printing, is the first technology that provides simultaneous jetting of different types of model materials. Available on the Connex family of 3D printing systems, PolyJet Matrix gives you the ability to closely emulate the look, feel and function of final products. It provides the foundation for 3D printing systems that can, in a single build process, print parts and assemblies made of several materials with different mechanical and physical properties. Moreover, PolyJet Matrix also allows on-demand fabrication of composite materials, called Digital Materials™.

Expanding the innovation leadership position that Objet established with the launch of its original PolyJet Technology, this totally unique technology brings an unprecedented level of flexibility and efficiency to 3D printing.

Objet’s patent-pending PolyJet Matrix technology works by jetting two Objet FullCure® photopolymer materials in pre-set combinations. The dual-jet process can combine materials in several ways, including the simultaneous use of two different rigid materials, two flexible materials, one of each type, any combination with transparent material, or two jets of the same material. Each material is funneled to a liquid system connected to the PolyJet Matrix block, which contains eight print heads. Two perfectly synchronized print heads are designated for each material, including the support material.

PolyJet Matrix Technology controls every one of the 96 nozzles in every print head. Preset composites of model materials are jetted from designated nozzles according to location and model type, providing full control of the structure of the jetted material and hence of its mechanical properties. This enables each composite material, called a Digital Material, to provide specific values for tensile strength, elongation to break, HDT and Shore A values.

The materials are jetted in ultra-thin layers onto the build tray until the part is complete. Each photopolymer layer is cured by UV light immediately after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing. The gel-like support material, specifically designed to support complicated geometries, is easily removed by hand and water jetting.

• Provides on-the-fly fabrication of Digital Materials, composite materials that closely emulate the mechanical properties of the design
• Enables the combination of black and white rigid materials, creating a wide range of grayscales suitable for consumer electronics and other applications
• Eliminates the need to design, print, and glue together separate model parts made with different materials in order to create a complete model, saving printing and post-processing time
• Reduces the risk of error when creating complex, double injection molds, as the majority of testing can be performed on early stage prototypes instead of requiring silicon molds
