PolyJet™

Using a range of UV acrylic based polymers, PolyJet^TM technology precisely jets UV plastics in high resolution layers down to 16 microns; creating a smooth, accurate parts requiring minimal finishing.  PolyJet^TM is the unsurpassed solution in high productivity, flexibility and model quality to shorten your product design-to-manufacturing cycle. The technology uses environmentally stable, fully-cured materials for safe, non-toxic use in office environments. The PolyJet^TM process can dramatically reduce the risk of error when creating complex molds for double injection by enabling the majority of testing to be performed on early stage prototypes instead of requiring flexible plastic castings.

The head travels along the X-axis (similar to a line printer) depositing a single super-thin layer of photopolymer resin onto the build tray. Immediately after building each layer the UV bulbs alongside the jetting bridge emit UV light which immediately cures each layer. This step eliminates the additional post curing required by other technologies.

The internal jetting tray descends with extreme precision as the jet heads continue building, layer by layer, until the model is complete. Sophisticated software tools enable all heads to work in perfect harmony, synchronizing the deposit of materials onto the tray. This results in a perfectly even and smooth surface. Two different photopolymer materials are used for building: one, the actual model resin, the other, a water saluable,  gel-like material for support. The geometry of the support structure is preprogrammed to utilize complicated geometries, such as cavities, overhangs, undercuts, delicate features, and thin-walled sections. The unfinished parts are then placed in a waterjet machine which easily removes the support material, leaving a smooth, clean surface.

The PolyJet^TM process uses the full line of FullCure® model and support materials including the Translucent 720, opaque VeroBlue, VeroWhite and VeroBlack. Also available are the flexible rubber-like resins TangoGray, TangoBlack, and TangoPlus.

Dinsmore and Associates proudly uses PolyJet^TM technology to create high resolution, tight tolerance items such as medical devices, surgical tools, electrical panel components, valves, or parts for any industry.
