RESIONE TH72 Flexible Tough 3D Printer Resin - Durable Miniature Resin

In this review of the RESIONE TH72 flexible tough resin, the bottom line is simple: it is best for modelers who need durable, bendable figures and small parts that survive drops and handling. The single biggest reason to buy is long-lasting toughness combined with high elongation, which means printed miniatures, capes, hair and thin parts take impacts and bending without cracking. The review focuses on real-world use: durability in outdoor weather, low water absorption, and how TH72 can be blended to toughen other resins.

Key Features

• Impact resistant prints: TH72 prints withstand accidental drops and can be bent or folded at wall thicknesses under 3mm without breaking.
• Long-lasting toughness: Prints retain strength after sun and rain exposure and high-temperature drying, showing good weather resistance over time.
• Hollowed model reliability: Hollowed prints do not develop slow internal cracks because the resin cures reliably even in thin sections.
• Very low water absorption: With about 0.6% water uptake over 48 hours, parts resist softening and moisture-induced cracking in humid or short underwater use.
• Toughening additive: Mixing TH72 at around 40% into rigid resins noticeably increases toughness while keeping reasonable strength.

Who It's For

This resin suits hobbyists and professional modelers who produce figurines, especially parts like hair, capes, swords and other thin, fragile details that commonly snap during handling or support removal. It is also a good choice for creators who need parts that can survive short-term outdoor exposure or occasional immersion without losing toughness.

Those seeking maximum surface detail or flawless first-layer adhesion may find mixed results reported by other users; if absolute dimensional rigidity or the crispest possible print finish is the top priority, consider pairing TH72 carefully with your printing and exposure parameters or using it as a modifier rather than the primary resin.

Pros & Cons

Pros

• Excellent durability and impact resistance for small parts and miniatures.
• Maintains toughness after weather exposure and high-temperature post-dry, offering good longevity.
• Low water absorption makes parts stable in humid or brief underwater conditions.
• Works as a toughening agent when blended into rigid resins.

Cons

• Print quality and adhesion have mixed feedback, so fine-tuning exposure and bed preparation may be necessary.
• Flexibility may reduce perceived surface stiffness for applications that require fully rigid parts.

Our Verdict

RESIONE TH72 is a practical choice for anyone printing miniatures or delicate elements that must endure handling or outdoor conditions. Its combination of impact resistance, long-term toughness, and low moisture uptake makes it good value for modelers who prioritize durability; users seeking perfect adhesion or maximum surface rigidity should be prepared to test print settings or use TH72 as a modifier.

Frequently Asked Questions

Can TH72 prints be used outdoors?
Yes, the resin shows good weather resistance and retains toughness after sun and rain exposure and high-temperature drying.

Will hollowed prints crack over time?
Hollowed models printed in TH72 are less likely to crack because the resin cures reliably even in thin sections.

Can I mix TH72 with other resins?
Yes, adding about 40% TH72 to a rigid resin increases toughness while keeping reasonable strength.
