PolyJet 3D Printing Service
Multi-material printing in full color with smooth surfaces
About PolyJet 3D printing
With our automated PolyJet printers, we can quickly and reliably build parts with surface quality similar to injection-molded items. Unlike injection molding, we can build parts in any combination of colors—from single-color goods to fully textured items. Available in both glossy and matte finishes, our full-color PolyJet process is ideal for most consumer-facing items where injection molding would otherwise be used and where color requirements extend beyond white or black.
Sample Applications
Digital Anatomy
With the ability to produce full-color parts, including transparent elements, RapAdd MFG's automated PolyJet service is ideal for patient-specific anatomy models delivered quickly and cost-effectively.
End use parts
With near-perfect surface finish and the ability to produce cost-efficient parts in any color (or combine multiple colors in one part), PolyJet is perfect for producing end-use items for consumer goods.
Promotional Items
By producing parts in all available colors, it is possible to embed logos and other brand identifiers directly into the item. No tooling required.
