PolyJet Multi-Color Design Guide

PolyJet Multi-Color builds prototypes, models and other parts in full color, including gradients and graphic textures. These design guidelines provide instructions for specific design considerations, including file exporting procedures and color selection for multi-color parts.

Create prototypes, models and patterns in unparalleled resolution and detail with PolyJet. See your design come to fruition in vivid color and end-product feel. With over 100 material combinations to choose from, you can incorporate diverse material properties and aesthetics directly into your component.

There are two file formats utilized for multi-color PolyJet parts: STL or VRML. Use of either option depends on the part’s color and transparency needs. The file formats assign color and texture graphics to parts in unique ways.

STL

Shell-based format (STL) is used when a colored model requires the use of a clear material or color tinted transparencies, such as with medical models that utilize clear material to show interior anatomical features or a colored display unit with a clear window. Color and transparency are assigned within the assembly with a RGD color code from the PolyJet Color Guide.

VRML

VRML Virtual Reality Modeling Language (VRML) format is ideal for parts designed with opaque colors or a colored graphic texture. VRML (.wrl) is a standard file format for representing 3D interactive graphics that provides the capability to apply texture to a model. VeroClear™ material or translucent colors cannot be used in this format.

Texture & UV Mapping 

Color by Texture / UV Mapping Texture mapping, also known as UV mapping, is the process of adding an image or graphics to 3D geometry. Color information is stored in a 2D image file, which is related to the coordinates of the mesh. This type of file can show the most detailed color information.
