DraftGrey: Fast and Affordable PolyJet Prototyping

Technical Overview

DraftGrey is a rigid PolyJet photopolymer developed specifically for high-speed, low-cost concept modeling. As a single-material solution, it allows designers and engineers to print early-stage prototypes at an accelerated pace, significantly reducing development cycles. Its key differentiator is its formulation for 'Draft' or 'Super High Speed' print modes, enabling the rapid production of models for design validation without the cost associated with specified materials.

Performance for Concept Validation

With a medium-grey tone and smooth surface finish, DraftGrey delivers professional-looking prototypes suitable for visual assessment, stakeholder presentations, and ergonomic evaluation. While not intended for functional testing, it offers sufficient rigidity (Shore D 83-86) and dimensional stability to accurately represent final product geometry for form and fit checks. Its properties are optimized for visual and tactile feedback during the earliest stages of product development.

Design and Processing Guidelines

DraftGrey is compatible with a range of Stratasys PolyJet 3D printers. It is engineered for straightforward processing with minimal post-processing requirements. For complex geometries, it is compatible with the Stratasys support materials.

Lifecycle: From Concept to Validation

This material is positioned exclusively for the initial stages of the product lifecycle. It serves as the ideal bridge from digital design to physical object, enabling teams to quickly and affordably test multiple design variations. Use DraftGrey to refine concepts, confirm ergonomics, and validate part geometry before committing to more expensive materials or tooling for functional prototyping or final production.
