3D Blend ECO Resin (Skin, 1kg)

Description

3D Blend ECO Resin is an economical standard resin with low odor, a smooth surface and easy, forgiving printing.

It is designed for high-volume everyday printing — prototypes, figures, school projects and batch production — where cost per print matters as much as quality.

Key features

• Best value per kilogram in the range
• Forgiving — wide exposure window, easy first prints
• Low odor
• Smooth surface straight off the plate
• Good toughness for a standard resin — 8.8% elongation at break

Applications

• Prototypes and fit checks
• Figures, toys and decorative items
• Education and makerspaces
• Batch production of small parts

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. Remove the build plate and let excess resin drip back into the vat (10–15 min)
2. Wash in IPA (95%+) for 2–3 min, then in a second, cleaner IPA bath for 1–2 min — do not exceed 10 min in total
3. Remove supports while the part is still slightly soft for cleaner marks
4. Dry completely with compressed air or leave 15–30 min — curing a wet part causes white haze

UV post-curing (polymerization)

Parameter	Value
Wavelength	405 nm (385–410 nm)
High-power curing box (≈200 mW/cm²)	1 min per side, in water
Standard curing station (40–60 W)	2–4 min, rotating
Sunlight	10–20 min, rotating
Note	Over-curing makes standard resin brittle — stop once the surface is no longer tacky

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
