What is VeroBlue?
VeroBlue (RGD840) is a legacy rigid blue acrylic photopolymer for PolyJet material jetting, available glossy, matte and in digital-material blends. It is used mainly for colour-differentiated aesthetic prototypes, educational models and display parts, with 55 MPa tensile strength, 17 % elongation and Shore D 84 hardness. It is a UV-cured thermoset: notch-sensitive, softening near 50 °C, prone to UV yellowing, and held to roughly ±0.1 mm or ±0.1–0.2 % accuracy. VeroGray and VeroBlackPlus are the current general-purpose replacements. VeroBlue 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). VeroBlue has a yield strength of 48 MPa (6.96 ksi) and a tensile strength of 55 MPa (7.98 ksi) — weaker than 53% of polymer grades. Elongation at break is 17% and the elastic modulus is 2.5 GPa (0.363 Msi).

Physical4
VeroBlue 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 has a yield strength of 48 MPa (6.96 ksi) and a tensile strength of 55 MPa (7.98 ksi) — weaker than 53% of polymer grades. Elongation at break is 17% and the elastic modulus is 2.5 GPa (0.363 Msi).
Thermal11
VeroBlue is rated for continuous service to 45°C (113 °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).
Electrical4
VeroBlue has an electrical resistivity of 1×10¹² Ω·m.
Chemical & Environmental3
Corrosion resistance is very good (75/100), worse than 66% of polymer grades. UV resistance is poor.
Sustainability3
Producing a kilogram of VeroBlue takes about 120 MJ of energy and emits 6 kg of CO₂ — more than 73% of polymer grades. Typical recycled content is 0%.
Manufacturability5
VeroBlue's machinability is good (55/100, worse than 64% of polymer grades); weldability not recommended (5/100); formability not recommended (5/100).

Working with VeroBlue
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.
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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| acrylic monomer (isobornyl acrylate / acreactive diluent, sets Tg and shrinkage | 30 – 60 | 45 |
| urethane acrylate oligomertoughness / backbone | 15 – 30 | 22 |
| epoxy or polyester acrylate oligomer | 10 – 30 | 20 |
| photoinitiator (acylphosphine oxide typeUV cure at print head lamp | 0.1 – 3 | 1.5 |

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 — frequently asked
What is VeroBlue used for?
VeroBlue 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?
VeroBlue has a typical yield strength of 48 MPa (6.96 ksi) and a tensile strength of 55 MPa (7.98 ksi) — weaker than 53% of polymer grades. Strength varies by condition: see the 2 listed tempers.
Is VeroBlue easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% 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 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?
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.

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?
VeroBlue is rated for continuous use to about 45°C (113 °F), and briefly to 60°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
