3D Blend Flexible Resin (White, 500g)

Description

3D Blend Flexible Resin produces soft, rubber-like parts that bend, compress and spring back to their original shape instead of cracking.

Use it wherever a part must flex in use — seals, gaskets, grips, bumpers, wearable parts and cushioning lattices — or blend 10–30% into a standard resin to add toughness.

Key features

• Rubber-like — bends, stretches and recovers
• High elongation — typically over 100% before break
• Tear resistant and anti-folding
• Blendable — mix into standard resin to reduce brittleness

Applications

• Seals, gaskets and O-rings (non-critical)
• Grips, handles and soft-touch overmolds
• Bumpers, feet and vibration dampers
• Wearables, straps and cushioning lattices
• Flexible prototypes of rubber parts

Typical values for this resin type, compiled from comparable resins — indicative only, not a guaranteed specification for this batch.

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	10–12 mm
Lift speed	30–50 mm/min (slow, to avoid tearing soft layers)
Retract speed	150 mm/min
Wavelength	385–410 nm
Bottom exposure	40–50 s
Layer exposure	8–12 s (flexible resins need much longer exposure than standard)

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
High-power curing box (≈200 mW/cm²)	1–2 min per side, in water
Standard curing station (40–60 W)	4–6 min, rotating
Note	A full cure removes tackiness and sets the final elasticity

Tip: Support flexible parts generously and print at an angle; soft layers deform under their own weight. Wash briefly — long IPA soaks swell elastic resins.

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
