DraftGrey
High Concept Modeling Material
DraftGrey is a rigid material used exclusively with the Super High Speed print mode for concept modeling.
Models will have a medium opacity and smooth finish. Printing at 2x the speed of High Speed mode with a 57 microns layer thickness, DraftGrey is the cheapest and fastest way to model on Stratasys PolyJet 3D printers.

Behaviour and use
Main Uses
DraftGrey™ is a rigid material within the Vero family of PolyJet™ resins used exclusively with Super High Speed print mode. DraftGrey allows users to print concept models twice as fast as High Speed Mode, for the fastest time-to-part on the J835™ and J850™ 3D printers. Models made with DraftGrey have a medium opacity and a smooth finish.
Top Applications
- Concept designs
- Prototypes
- Draft models
