What is VeroBlue DM-BLEND?
VeroBlue DM-BLEND is VeroBlue in the DM-BLEND grade — use when a single part needs graded stiffness, overmold-like soft zones or intermediate colours in one build. VeroBlue DM-BLEND has a yield strength of 48 MPa (6.96 ksi) and a tensile strength of 20 MPa (2.9 ksi) — weaker than 53% of polymer grades. Elongation at break is 60% and the elastic modulus is 0.6 GPa (0.087 Msi). VeroBlue DM-BLEND has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 53°C (127 °F). GLOSSY is the default condition FabDigit quotes; DM-BLEND is available on request or by drawing note.

Physical4
VeroBlue DM-BLEND has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 53°C (127 °F).
Mechanical14
VeroBlue DM-BLEND has a yield strength of 48 MPa (6.96 ksi) and a tensile strength of 20 MPa (2.9 ksi) — weaker than 53% of polymer grades. Elongation at break is 60% and the elastic modulus is 0.6 GPa (0.087 Msi).
Thermal11
VeroBlue DM-BLEND is rated for continuous service to 40°C (104 °F). It conducts heat at 0.2 W/m·K (0.116 BTU/hr·ft·°F), worse than 56% of polymer grades. Thermal expansion is 80 µm/m·K (44.4 µin/in·°F).

Working with VeroBlue DM-BLEND
Is VeroBlue easy to machine?
Drills, taps and sands easily with sharp tools and light feeds, but is notch-sensitive and chips at thin edges; keep cutting speeds low to avoid heat softening near 50 °C.
Can VeroBlue be welded?
Not weldable; join with cyanoacrylate or UV-cure acrylic adhesive, or mechanical fasteners with brass heat-set inserts installed at low temperature.
Can VeroBlue be formed, bent or molded?
Not mouldable — the part geometry is produced only by PolyJet jetting and UV cure; design walls ≥1 mm and expect ±0.1 mm/±0.1–0.2 % accuracy.
What surface finishes work on VeroBlue?
Remove SUP705/706 support by waterjet or NaOH bath, then wet-sand and polish for gloss; primer plus acrylic or urethane paint (or vacuum metallising) is recommended to block UV-driven yellowing.
VeroBlue chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

VeroBlue DM-BLEND — frequently asked
What is VeroBlue DM-BLEND used for?
VeroBlue DM-BLEND is typically used for color prototypes, educational models and display parts. In short: legacy colour PolyJet resin; colour-coded prototype parts; largely superseded by VeroGray.
What is the yield strength of VeroBlue DM-BLEND?
VeroBlue DM-BLEND has a typical yield strength of 48 MPa (6.96 ksi) and a tensile strength of 20 MPa (2.9 ksi) — weaker than 53% of polymer grades. Strength varies by condition: see the 2 listed tempers.
Is VeroBlue DM-BLEND easy to machine?
Not especially — machinability is rated poor (30/100, worse than 87% of polymer grades). Drills, taps and sands easily with sharp tools and light feeds, but is notch-sensitive and chips at thin edges; keep cutting speeds low to avoid heat softening near 50 °C.
Can VeroBlue DM-BLEND be welded?
Not readily — weldability is rated not recommended (5/100). Not weldable; join with cyanoacrylate or UV-cure acrylic adhesive, or mechanical fasteners with brass heat-set inserts installed at low temperature.
What surface finishes work on VeroBlue DM-BLEND?
Remove SUP705/706 support by waterjet or NaOH bath, then wet-sand and polish for gloss; primer plus acrylic or urethane paint (or vacuum metallising) is recommended to block UV-driven yellowing.
Can VeroBlue DM-BLEND be formed, bent or molded?
Not mouldable — the part geometry is produced only by PolyJet jetting and UV cure; design walls ≥1 mm and expect ±0.1 mm/±0.1–0.2 % accuracy.
What is the maximum service temperature of VeroBlue DM-BLEND?
VeroBlue DM-BLEND is rated for continuous use to about 40°C (104 °F), and briefly to 60°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
