PolyJet is one of the most advanced 3D printing technologies due to its ability to manufacture parts out of multiple materials and colors at the same time. This makes it widely used for prototyping in the automotive, medical, and consumer product industries. It also finds use in the film industry in the manufacture of highly detailed props.
PolyJet materials are photopolymers that use UV light to cure the resins. The liquid resin is jetted in extremely thin layers onto a build platform and is immediately cured by UV light. The process is similar to that of inkjet printers. Just as an inkjet can print different colors, a PolyJet printer can use different materials and colors to create composite parts. An example of this would be simulating an overmolded product that has a rigid body with softer overmolding for handholds and grips. This is a unique benefit of PolyJet: the materials used when 3D printing in PolyJet resins can be combined in a single product.
|Application||Light duty, functional and visual prototypes, multi-material parts, multicolor parts|

3D printing in PolyJet resins allows for the manufacture of transparent parts with materials that are designed to simulate standard thermoplastics such as acrylic. This material can be used to create highly detailed, functional prototypes of parts that need to be transparent.
|Tensile Strength (MPa) (X, Y, Z)||Elongation at Break (%) (X, Y, Z)||Hardness (Shore D)||Colors and Clarity||Heat Deflection Temperature (℃)|
Using rigid plastic for 3D printing in PolyJet photopolymers allows for a wide range of colors. Each of these plastics has the same mechanical properties and only differs in terms of its color. These materials are ideal for creating detailed functional and visual prototypes as well as manufacturing fixtures. Colors can be mixed, enabling PolyJet parts to have an unmatched color palette.
|Tensile Strength (MPa)||Elongation at Break (%)||Hardness (Shore D)||Colors and Clarity||Heat Deflection Temperature (℃)|
|50-65||10-25||83-86||Opaque, Gray (RGD850), Black (RGD875), White (RGD835), Yellow (RGD836), Cyan (RGD841), Magenta (RGD851)||45-50|
Using flexible plastic for 3D printing in PolyJet photopolymers can simulate rubber or other low durometer plastics. This enables the creation of multi-material prototypes that simulate overmolded injection molded products. These materials can be used exclusively or combined with other rigid PolyJet resins.
|Tensile Strength, Yield (MPa)||Elongation at Break (%)||Hardness (Shore A)||Colors and Clarity||Tensile Tear Resistance (kg/cm)|
|0.8-1.5||170-220||26-28||Clear, Translucent (FLX930) Opaque, Black (FLX980)||2-4|
Digital material is a phrase used to describe the unique capabilities of 3D printing in PolyJet photopolymers. Each of the above materials can be combined with each other in the same part. This allows for multi-material and multicolor parts without having to print parts separately and assemble them afterward. The result is highly complex prototypes that look like a complete product with all of the materials and colors intended for the final production version.
