Temporary resin4 shades
Outlined teeth do not have a colour preview yet. You can still select them by name.
A1–D4 and BL1–BL4 previews help you choose a shade code; they are not measurements of the material colour or translucency. Screens vary; confirm with a physical sample.
Colours and pack weights follow the catalogue; reference codes and availability are confirmed with the team.
Technical reference
The supplied technical sheet uses the name C&B. Its values are shown as a reference profile; equivalence to this Temporary product must be confirmed.
Mechanical properties
| Property | C&B |
|---|---|
| Tensile strength | 30.00 MPa |
| Flexural strength | 30.98 MPa |
| Flexural modulus | 927.13 MPa |
| Elongation at break | 32 % |
| Hardness | 80–90 Shore D |
Selected reported values. Results depend on formulation and specimen conditioning. Reported mechanical values carry a ±10% tolerance; hardness is presented as a range. Testing references: ASTM D638 (tensile), D790 (flexural) and D2240 (hardness).
Reference print settings & test conditions
Catalogue reference settings for matching materials, tested on ELEGOO MARS 3. Confirm resin variant and batch, and calibrate on the actual printer; these are not ready-to-use GK3 or universal printer presets.
| Property | C&B |
|---|---|
| Bottom exposure | 20–30 s |
| Normal exposure | 3–6 s |
| Layer height | 0.05 mm |
|---|---|
| Bottom/normal lift distance | 6 mm |
| Bottom lift speed | 60 mm/min |
| Normal lift | 80 mm/min |
| Retract speed | 150 mm/min |
| Rest after retract | 2–3 (unit not stated in source) |
| Test platform | ELEGOO MARS 3 |
| Test screen | 6.6-inch monochrome LCD |
| Irradiance | 3,500–4,500 µW/cm² |
Lift distance by screen size
| Below 7 inches | 6 mm |
|---|---|
| 7–10 inches | 8–10 mm |
| 10.1 inches | 11 mm |
| 13.3 inches | 14 mm |
| 15 inches | 15 mm |
These distances apply to the conventional release-film setup described in the source. Gingiva Mask calls for a 20–30% increase in lift distance. Validate against the actual machine and film. Bottom layer count = bottom thickness ÷ layer height + 1. For 0.40 mm at 0.05 mm per layer: 9 bottom layers. Mix resin thoroughly before printing. Run a calibration specimen whenever material, printer, light output, layer height or release film changes. Check detail, fit and separation before production.
Test specimen conditions
| Source test environment | 23 ± 2°C |
|---|---|
| Relative humidity | 50 ± 5% |
| Test specimen curing medium | water |
| Curing time per side | 1 min per side |
| Wavelength | 405 nm |
| Irradiance | 200 mW/cm² |
These are test-coupon conditions. They are not a validated clinical post-curing protocol for every SPECTRA resin.
Washing & post-curing
Select the wash medium from the exact resin instructions; the reference distinguishes IPA-cleanable materials from water-washable model resin. Remove residual liquid, dry and inspect before curing. Final properties depend on wavelength, irradiance, time and part geometry; clinical applications require their validated protocol. Follow the safety data sheet and collect contaminated wash liquid for appropriate disposal.
