Digital Materials
Digital Materials (DM) is a class of PolyJet builds rather than a single resin: two base photopolymers are jetted in controlled voxel ratios to produce a continuous range of Shore hardness or colour in one print, spanning rigid blends (DM-ABS-PLUS, DM-ABS2, DM-RGD, DM-CLEAR, DM-HT, DM-MED) and rubber-like A30 to A95 grades.

What is Digital Materials?
Digital Materials (DM) is a class of PolyJet builds rather than a single resin: two base photopolymers are jetted in controlled voxel ratios to produce a continuous range of Shore hardness or colour in one print, spanning rigid blends (DM-ABS-PLUS, DM-ABS2, DM-RGD, DM-CLEAR, DM-HT, DM-MED) and rubber-like A30 to A95 grades. Engineers use it to print multi-durometer or multi-colour assemblies without tooling or secondary overmoulding; the default rigid blend gives 57 MPa tensile strength, 30% elongation, Shore D 86 and 2.8 GPa modulus. Service temperature is limited to about 50 °C, parts are not weldable and colour stability under UV is poor, so DM suits prototypes rather than end-use parts. Digital Materials has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 50°C (122 °F). Digital Materials has a tensile strength of 57 MPa (8.27 ksi), stronger than 65% of polymer grades. Elongation at break is 30% and the elastic modulus is 2.8 GPa (0.406 Msi).
What is Digital Materials used for?

Limitations

- Absorbs moisture — dry before molding — 1.7%, worse than 94% of polymer grades
- Degrades in UV without stabilisers — 20/100, worse than 88% of polymer grades

Working with Digital Materials
Is Digital Materials easy to machine?
Drills, taps and sands readily with sharp tools and low speed; keep cutting cool — parts soften and gum above ~55 °C, and thin sections are notch-sensitive.
Can Digital Materials be welded?
Not weldable; join with cyanoacrylate or UV-cure acrylic adhesive, or print the assembly as one multi-material body.
Can Digital Materials be formed, bent or molded?
Shaped only by the jetting process — set blend ratio and voxel layout in the print job; support material must be waterjetted/soaked out before post-cure, and thin flexible walls need generous support.

Digital Materials — frequently asked
What is Digital Materials used for?
Digital Materials is typically used for multi-durometer overmolds, gradient color models and combined rigid-flexible assemblies. In short: multi-durometer in one print; A30–A95 hardness range; no tooling for overmoulds.
What is the tensile strength of Digital Materials?
Digital Materials has a typical tensile strength of 57 MPa (8.27 ksi) — stronger than 65% of polymer grades. Strength varies by condition: see the 13 listed tempers.
Is Digital Materials easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drills, taps and sands readily with sharp tools and low speed; keep cutting cool — parts soften and gum above ~55 °C, and thin sections are notch-sensitive.
Can Digital Materials be welded?
Not weldable; join with cyanoacrylate or UV-cure acrylic adhesive, or print the assembly as one multi-material body.

Shaped only by the jetting process — set blend ratio and voxel layout in the print job; support material must be waterjetted/soaked out before post-cure, and thin flexible walls need generous support.
What is the maximum service temperature of Digital Materials?
Digital Materials is rated for continuous use to about 50°C (122 °F), and briefly to 70°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Digital Materials DM-ABS-PLUS and Digital Materials DM-ABS2?
DM-ABS-PLUS is the default condition — default DM: pick for snap fits, thin-wall housings and functional prototypes needing the highest impact strength and HDT in the PolyJet range. DM-ABS2: choose over Digital ABS Plus for very thin walls (<1.2 mm) and better dimensional stability at similar toughness.
