Working with VeroBlackPlus DM-GREY
Is VeroBlackPlus easy to machine?
Drill, tap and sand at low speed with sharp tools and light feed — the cured acrylate is notch-sensitive and softens near 50 °C, so avoid dry high-speed cutting.
Can VeroBlackPlus be welded?
Thermoset, so no thermal welding; bond with cyanoacrylate, UV-cure acrylate or epoxy after light scuffing and degreasing.
Can VeroBlackPlus be formed, bent or molded?
Shape is defined entirely by the print — no post-forming; orient thin features to build direction, allow ~0.1 mm/100 mm growth and design ≥0.6 mm walls, then water-jet or NaOH-soak the SUP support gel away.
What surface finishes work on VeroBlackPlus?
Sands from 400 to 2000 grit and takes primer, solvent-free paint and clear lacquer well; the as-printed glossy black polishes to near-piano finish but UV clear-coat is recommended to slow yellowing/embrittlement.

VeroBlackPlus DM-GREY — frequently asked
What is VeroBlackPlus DM-GREY used for?
VeroBlackPlus DM-GREY is typically used for visual prototypes, consumer electronics housings, black cosmetic parts and assembly fit checks. In short: deep black PolyJet resin; sharp cosmetic detail; prototype use, not functional.
What is the yield strength of VeroBlackPlus DM-GREY?
VeroBlackPlus DM-GREY has a typical yield strength of 50 MPa (7.25 ksi) and a tensile strength of 55 MPa (7.98 ksi) — stronger than 52% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is VeroBlackPlus DM-GREY easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drill, tap and sand at low speed with sharp tools and light feed — the cured acrylate is notch-sensitive and softens near 50 °C, so avoid dry high-speed cutting.
Can VeroBlackPlus DM-GREY be welded?
Not readily — weldability is rated not recommended (10/100). Thermoset, so no thermal welding; bond with cyanoacrylate, UV-cure acrylate or epoxy after light scuffing and degreasing.
What surface finishes work on VeroBlackPlus DM-GREY?
Sands from 400 to 2000 grit and takes primer, solvent-free paint and clear lacquer well; the as-printed glossy black polishes to near-piano finish but UV clear-coat is recommended to slow yellowing/embrittlement.
Can VeroBlackPlus DM-GREY be formed, bent or molded?
Shape is defined entirely by the print — no post-forming; orient thin features to build direction, allow ~0.1 mm/100 mm growth and design ≥0.6 mm walls, then water-jet or NaOH-soak the SUP support gel away.
What is the maximum service temperature of VeroBlackPlus DM-GREY?
VeroBlackPlus DM-GREY 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.
What is the difference between VeroBlackPlus GLOSSY and VeroBlackPlus HQ16?
GLOSSY is the default condition — default choice for visual models: deepest black, highest gloss and best measured strength. HQ16: use for fine text, thin walls and sharp edges; slower build, slightly better strength consistency. Yield strength is 50 MPa in GLOSSY versus 53 MPa in HQ16.
