water-washable standard resin | Choose to avoid IPA handling in shops/classrooms; slightly weaker and noticeably more moisture-sensitive/hygroscopic after cure. | 38 | 44 | 6 | 80 Shore D |
Fast-print / high-speed draft resin | Use for quick iteration at thick layers (0.1–0.3 mm); mechanicals and surface finish are lower than standard. | 40 | 45 | 12 | 79 Shore D |
opaque grey / white / black standard resin | Standard choice for appearance prototypes and painted masters — pigment improves cure control and edge definition, slightly reduces cure depth. | 48 | 55 | 7 | 83 Shore D |
glass/ceramic-filled rigid standard resin | Use for stiff, dimensionally stable jigs and thin-wall housings that must not creep; very stiff but brittle and abrasive to tooling. | — | 68 | 2.5 | — |
What is Grey ABS-like?
Grey ABS-like is Grey in the ABS-like grade — pick when snap-fits, thin walls or drop resistance matter — much higher elongation and impact at the cost of stiffness and HDT. Grey ABS-like has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 45 MPa (6.53 ksi) — weaker than 64% of polymer grades. Elongation at break is 25% and the elastic modulus is 1.8 GPa (0.261 Msi). Grey ABS-like has a density of 1.15 g/cm³ (0.0415 lb/in³), lighter than 57% of polymer grades. Its glass-transition temperature is 60°C (140 °F).

Working with Grey ABS-like
Is Grey easy to machine?
Drills, mills and sands easily with sharp tools and light feeds, but is notch-sensitive — pre-drill, avoid heat build-up (softens near 60 °C) and wet-sand to prevent dust.
Can Grey be welded?
Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or by wicking uncured resin into the seam and UV-curing.
Can Grey be formed, bent or molded?
Formed only by vat photopolymerisation: 0.025–0.1 mm layers, supports and hollowing with drain holes, then IPA wash and 5–30 min UV post-cure at 40–60 °C; expect ~0.5–2 % cure shrinkage and warp on thick sections.
What surface finishes work on Grey?
Sands from 400→2000 grit and buffs to gloss; primer-filler plus acrylic/PU paint is standard, clear coat restores transparency, and electroplating or vacuum metallising works after a conductive base coat — always apply UV-blocking coating for outdoor use.
Grey 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.

Grey ABS-like — frequently asked
What is Grey ABS-like used for?
Grey ABS-like is typically used for cosmetic prototypes, concept and display models, master patterns for silicone moulds and vacuum casting, painted appearance samples, fit-check and assembly mock-ups and fine-detail figurines and scale models. In short: workhorse SLA visual resin.
What is the yield strength of Grey ABS-like?
Grey ABS-like has a typical yield strength of 38 MPa (5.51 ksi) and a tensile strength of 45 MPa (6.53 ksi) — weaker than 64% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is Grey ABS-like easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drills, mills and sands easily with sharp tools and light feeds, but is notch-sensitive — pre-drill, avoid heat build-up (softens near 60 °C) and wet-sand to prevent dust.
Can Grey ABS-like be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or by wicking uncured resin into the seam and UV-curing.
What surface finishes work on Grey ABS-like?
Sands from 400→2000 grit and buffs to gloss; primer-filler plus acrylic/PU paint is standard, clear coat restores transparency, and electroplating or vacuum metallising works after a conductive base coat — always apply UV-blocking coating for outdoor use.

What is the maximum service temperature of Grey ABS-like?
Grey ABS-like is rated for continuous use to about 42°C (108 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
