3D Blend Pro Model Resin (Skin, 1kg)

Description

3D Blend Pro Model Resin is a high-precision dental model resin for restorative work: crisp margins, low shrinkage and a scratch-resistant surface after curing.

It is tougher than standard model resins (192 J/m impact, 25.5% elongation), so dies and thin sections survive handling in the lab.

Key features

• High precision — low shrinkage, sharp margins
• Very tough — 192 J/m notched impact
• Scratch resistant after UV curing
• Natural color that shows margins clearly

Applications

• Restorative and die models
• Crown and bridge working models
• Implant models
• Study models

How to print

1. Bring resin and room to 20–30 °C — cold resin is thick and causes failed prints
2. Shake the bottle for 1–2 minutes (or roll it) until no sediment remains
3. Check the FEP/ACF film for holes and clean the build plate; level the plate if needed
4. Pour resin into the vat up to the MAX line
5. In your slicer (Chitubox, Lychee, etc.) enter the print settings below, orient parts at 30–45° and add supports
6. Hollow large models (2–3 mm wall) and add drain holes to save resin and avoid suction
7. Run an exposure test (e.g. RERF or validation matrix) the first time you use this resin on your printer
8. Print, then let the plate drip for 10–15 min before removing parts

Recommended print settings (UV exposure)

Setting	Starting value
Layer height	0.05 mm
Bottom layers	4–6
Lift distance	6 mm (8–10 mm on 7–10″ screens, 11–15 mm on 10–15″ screens)
Lift speed	60–80 mm/min
Retract speed	150 mm/min
Wavelength	385–410 nm
Bottom exposure	20–30 s
Layer exposure	2.5–4.5 s

Starting values tested on a 6.6″ mono LCD (3500–4500 µW/cm²). Adjust for your printer’s light power: a stronger screen needs shorter exposure; a weaker or ageing screen needs longer.

Washing

1. Clean in fresh IPA (95%+), ideally ultrasonic: 1–2 min first bath, 2–3 min second bath
2. Blow dry with an air gun immediately after washing
3. Finish and polish according to standard laboratory practice
4. Check fit on the model before clinical use

UV post-curing (polymerization)

Parameter	Value
Wavelength	405 nm (385–410 nm)
Dental curing unit (≈200 mW/cm²)	30–60 s per side, in water or glycerin
Standard curing station (40–60 W)	5–10 min, rotating
Note	Curing in water/glycerin prevents the oxygen-inhibited tacky layer. Follow your validated protocol for each indication

Tip: After cleaning, cure in water under 405 nm UV for 2 min for maximum scratch resistance.

Storage & safety

• Store sealed in the original bottle at 15–30 °C, away from sunlight, heat sources and moisture
• Shake or roll the bottle for 1–2 minutes before every print — pigments and fillers settle
• Shelf life: 24 months unopened (18 months for dental resins)
• Wear nitrile gloves and safety glasses; work in a ventilated room
• Skin contact: wash with soap and water. Eye contact: rinse 15 min and seek medical advice
• Dispose of uncured resin and contaminated IPA as chemical waste, never in the drain

For professional dental use only, by trained laboratory and clinical staff. Validate settings on your own printer and follow your local regulations for dental devices.
