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.

DraftGrey Material Properties

Behaviour and use

TENSILE STRENGTH

50-60 MPa

FLEXURAL STRENGTH

75-110 MPa

HDT

45-50 °C

IZOD IMPACT, NOTCHED

25-30 J/m

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.

PolyJet™ Technology

Advantages of 3D printing DraftGrey with a Stratasys PolyJet Machine

Proven Technology

Stratasys PolyJet 3D Printers are based on proven technology, which creates precise prototypes that set  the standard for finished-product realism. Their fine resolution makes complex shapes, intricate details  and smooth surfaces possible.

Advanced 3D Printing

PolyJet 3D Printing works by jetting layers of liquid photopolymer onto a build tray and instantly curing them with UV light. The fine layers build up to create a precise 3D model or prototype. Models are ready to handle right out of the 3D printer, with no post-curing needed.

Better ideas, easier sell

Stratasys PolyJet 3D Printers improve communication and collaboration because they produce amazingly  accurate representations of your ideas that you can share with your team and your clients for a faster, more confident buy-in.
