AI Verdict
This 405nm UV-curing urethane resin offers 65D flexibility and high impact resistance, making it suitable for functional parts or as an additive to toughen other resins.
This resin is a situational fit because its high impact resistance and 65D flexibility are excellent for specific applications like functional flexible parts or as an additive to fortify other resins. However, its challenges with support removal and potential for lower detail when used pure mean it's not a universal solution for all 3D printing needs.
If you need higher detail for miniatures or rigid, non-flexible parts, look for an ABS-like or engineering resin with a higher Shore D hardness and better reported resolution.

Pros
- Printed objects bend 180° without breaking, demonstrating high toughness.
- Provides significant impact resistance, allowing models to withstand accidental drops.
- Effectively reduces the fragility of other resins when mixed, improving durability.
- Creates parts that feel like rubber, returning to their original state after bending.
- Easier to print compared to other flexible resins, especially at 25°C or higher.
Cons
- Support removal is difficult and messy, requiring snipping rather than breaking off.
- Pure prints can have lower resolution and detail compared to other resins.
- Washing is more tedious than with standard resins.
- Clear version may appear cloudy and is reported to be the least effective variant.
- Requires precise print settings and post-processing for optimal flexibility and impact resistance.
Dimension Scores
When printed pure, the resolution of Tenacious resin is reported to be worse than other resins, impacting fine detail.
While claimed to be easier to print than other flexible resins and user-friendly, support removal is difficult and messy, and precise settings are crucial for success. [product spec, 9, 10]
This resin can be used standalone for flexible parts or as an additive (10-20% mix) to enhance the durability and impact resistance of other 405nm resins. [product spec, 2]
The resin offers 65D flexibility and high impact resistance, allowing thin prints to bend 180° without breaking and models to withstand accidental drops. [product spec, 1]
Best For
- Creating miniature models that need to survive drops, like tabletop game pieces. [product spec]
- Producing functional flexible parts such as O-rings, washers, or braces. [product spec]
- Users who want to increase the durability and impact resistance of their existing, more brittle resins. [product spec]
- Prototyping flexible objects where elasticity is key. [product spec]
Not Recommended For
- Printing highly detailed miniatures or models where crisp resolution is the top priority.
- Applications requiring rigid, non-deforming parts.
- Users who prefer not to mix resins or deal with calibration for additives.
Watch Out For
- Removing supports from prints is a messy, difficult process that often requires snipping, leaving a layer of support marks.
- The resin, particularly the clear variant, can lead to prints that feel soft and easily deform, and may show random deformation over time post-cure.
- Achieving advertised flexibility and impact resistance is highly dependent on using correct print settings and proper wash/cure procedures.
- When used as an additive, it elevates exposure times, necessitating resin calibration.

What Buyers Say
Many users aren't just printing with this resin straight; they're actually mixing it into their standard resins to make them less brittle, which is a clever workaround for fragile prints. While it's marketed for its flexibility, some initially found their prints weren't as flexible as expected until they dialed in the specific print settings and post-processing. The biggest headache seems to be getting supports off, as they don't just snap but require careful snipping, leaving marks. Also, if you're going for the clear version, be prepared for a potentially cloudy finish.
“Dude, I mixed this 4:1 with my regular resin and my minis actually survive falling off the table now, but getting those supports off was a nightmare, felt like I was doing surgery on a tiny plastic guy.”
Common Praise
- Models printed with a 10-15% mix can survive a 6-foot drop onto concrete without breaking.
- Makes miniatures significantly more resistant to physical damage and handling.
- Printed parts have a rubbery feel and can return to their original shape after bending.
- Successfully prevents breakage of otherwise fragile parts during painting or accidental drops.
Common Complaints
- Support structures are extremely difficult to remove cleanly, often requiring cutting and leaving residue.
- Pure prints can lack fine detail and have a lower resolution compared to other resins.
- The clear variant is reported to be cloudy and less effective than other colors.
- Prints can deform over time if not properly cured or if the resin dries out.
- Washing the pure resin prints can be more time-consuming and tedious.
Ownership Tips
- The flexibility and impact resistance are highly dependent on using the manufacturer's recommended print settings and proper wash/cure procedures.
- Mixing with other resins requires recalibrating exposure times to account for the additive.
- Prints, especially the clear ones, might become cloudy or show signs of deformation if not handled and cured correctly.
- The resin can be more expensive than standard resins, making its use as a pure printing material a cost consideration.
Frequently Asked Questions
Can I print with Siraya Tech Tenacious resin on its own?
Yes, you can print with it alone to create flexible and impact-resistant parts. However, some users report lower resolution and more tedious post-processing compared to other resins.
What is the best temperature to print this resin?
Siraya Tech recommends printing this flexible 405nm UV-Curing resin at 25°C or higher for optimal results. [product spec]
How does this resin improve other resins?
It's suitable as an additive to increase the strength and elasticity of other resins, reducing their fragility and improving durability, even for small models. [product spec, 2]
Is the clear version truly clear?
User feedback suggests the clear version can appear cloudy and may not perform as well as other Tenacious variants.
What kind of objects is this resin best for?
It's mainly used for miniature models needing drop resistance, O-rings, washers, tabletop game pieces, and other flexible prototypes due to its high toughness and flexibility. [product spec]
Buying Guide
When you're looking at flexible resins like this one, you need to understand that 'flexible' doesn't always mean 'squishy like silicone.' This resin offers a 65D hardness, which means it's more like a firm rubber, designed to bend and absorb impact without shattering. It's not just for making bouncy parts; it's also a secret weapon for making your brittle standard resin prints much tougher. You'll trade some fine detail for that durability, especially if you print it pure.
HIGH IMPACT RESISTANCE
This means your printed objects can take a hit, like falling off a desk, without breaking into pieces. Think of it like a phone case that absorbs shock, protecting the delicate parts inside. [product spec]
HIGH TOUGHNESS
Toughness allows a material to deform under stress without fracturing. For 3D prints, this means thin parts can bend significantly (up to 180°) without snapping, making them more resilient to everyday handling. [product spec]
SUITABLE AS AN ADDITIVE
This is a big one: you can mix this resin with other, more brittle resins (like standard grey) to give them some of Tenacious's impact resistance and flexibility. It's like adding a strengthening agent to make your regular prints less fragile. [product spec]
Alternatives
If you need extreme detail for display models or completely rigid, unyielding parts, look for a standard or ABS-like resin with a higher Shore D hardness. If you need even softer, more elastic parts, search for resins with a lower Shore A hardness.
