Flexible Tough 80A 3D Printer Resin - TPU-Like Black 1000g

Our review of the Flexible Tough 80A resin focuses on makers who need a TPU-like material that balances softness and strength. This resin is best for projects requiring repeated bending, cushioning, or shock absorption because its Shore 80A hardness delivers rubber-like toughness while still allowing fine detail. Print quality is generally high and the cured surface remains smooth and precise, so it's a practical choice for functional prototypes and consumer parts when flexibility and dimensional accuracy matter most.

Key Features

• Shore 80A softness: Provides a rubber-like feel that can be folded and bent repeatedly without immediate failure, making it suitable for flexible parts.
• High precision: Prints show clear detail and a smooth surface, with low impurity and minimal yellowing for accurate small features.
• Tear resistance: The cured material resists cracking and tearing under repeated flexing, useful for cushioning or shock-absorbing components.
• Broad compatibility: Works with most LCD and DLP printers and line scanning equipment that use 405nm UV-curing resins, simplifying setup.
• Low water absorption: Offers reliable resilience and dimensional stability in applications where moisture resistance matters.

Who It's For

The resin is aimed at designers, hobbyists, and small shops that need a relatively hard yet flexible material for phone cases, seals, washers, insoles, toys, and similar elastic parts. It is a good pick when you want printed parts that bend, twist, or compress while keeping fine detail.

Those who require absolute color accuracy or a pronounced metallic finish should look elsewhere, and users who need very soft rubbery parts below Shore 80A or extreme long-term fatigue resistance may prefer a different flexible formulation.

Pros & Cons

Pros

• Strong combination of flexibility and strength for parts that must bend repeatedly.
• High print precision with smooth surfaces and minimal yellowing over time.
• Good tear resistance and low water uptake for durable, dimensionally stable parts.

Cons

• Reported color accuracy issues mean the black shade can appear off in some prints; finishes like metallic effects are limited.
• Mixed reports on brittleness under some settings suggest tuning print exposure and post-cure may be necessary for best durability.

Specifications

Our Verdict

The Flexible Tough 80A resin is a practical choice for anyone needing a TPU-like material that keeps fine detail while offering cushioning and shock absorption. It represents good value when you prioritize bendability and print precision, but expect to tune exposure and post-cure and be prepared for some color variance in finished parts.

Frequently Asked Questions

Is this resin compatible with my LCD printer?
Yes, it is formulated for 405nm UV-curing and is compatible with most LCD and DLP printers and line scanning equipment.

Can printed parts be used for wearable items like insoles?
Yes, its low water absorption and resilience make it suitable for items that bend and compress, although long-term wear should be tested for your specific use.

Are there special safety steps before printing?
Shake well before use, wear gloves and a mask, and avoid skin contact; follow normal resin handling precautions and consult the seller with any issues.
