Speed Meets Suppleness: Mastering 150µm and 200µm Fast Printing with Siraya Tech Tenacious Flex on the Elegoo Saturn 3 Ultra

At Siraya Tech, we believe that high-performance materials shouldn't come at the cost of production speed. Traditionally, printing with flexible resins and elastomers meant slow, meticulous cycles and paper-thin layers.

With the arrival of the Elegoo Saturn 3 Ultra, we’ve unlocked a new tier of efficiency. Today, we’re showing you how to combine the rugged durability of our Tenacious Flex (Black) resin with 150µm and 200µm layer heights to achieve functional, rubber-like parts in record time.

Why Tenacious Flex? The 70A Advantage

ur Tenacious Flex Black is engineered for users who need more than just "bendable" plastic. With a Shore Hardness of 70A, this resin mimics the tactile feel and mechanical performance of industrial rubber.

Key Features:

1. High Impact Resistance: Ideal for protective cases, bumpers, and gaskets.

2. Extreme Elongation: It stretches and recovers without permanent deformation.

3. Low Suction Force: Unlike many soft resins, Tenacious Flex is designed to be easier on your release film (FEP/ACF), reducing the risk of print failures.

The Need for Speed: Why 150µm?

While 50µm is the standard for high detail, functional parts like handle grips, vibration dampeners, or footwear prototypes often prioritize mechanical integrity and speed.

By moving to 150µm (0.15mm) layers or 200µm (0.2mm), you reduce the total layer count by 66% and 75%. On a machine like the Saturn 3 Ultra, this means completing a large-scale project in hours rather than days. Thanks to the ACF film and the powerful light source of the Saturn 3 Ultra, 150µm and 200µm layers cure reliably while maintaining the tough, elastomeric properties Tenacious is known for.

Optimized Profile: Elegoo Saturn 3 Ultra + Tenacious Flex

To print at 150µm and 200µm, the UV light must penetrate deeper into the resin. We’ve dialed in these settings to ensure perfect adhesion and structural strength.

• 150µm Fast Print Settings (Recommended Temp: 25°C - 30°C)

200µm Fast Print Settings (Recommended Temp: 25°C - 30°C)

Pro Tip: Tenacious Flex is a high-performance resin that performs best when warm. Ensure your resin is at least 25°C before starting to maintain low viscosity for fast printing.

Why the Saturn 3 Ultra is the Perfect Partner

The Elegoo Saturn 3 Ultra features ACF (Advanced Compression Film), which provides a lower release tension compared to standard FEP. For a flexible resin, this is a game-changer.

As the build plate lifts, "sticky" elastomers can often pull or warp if the release force is too high. The ACF film allows Tenacious Flex to "pop" off the film effortlessly, even with the increased surface area of 150µm or 200µm layers. This synergy allows you to utilize the Saturn 3 Ultra’s high-speed motor settings without risking delamination.

Pro-Tips for Success

1. Support Heavily: Flexible resins can "sway" during the printing process. Use "Heavy" supports for your base and "Medium" for the rest of the model.

2. Wash & Cure: Wash thoroughly in IPA. For the best finish and to remove any tackiness, we recommend curing the part submerged in water for 10–15 minutes.

3. Orientation: Tilt your models at a 30-45 degree angle to minimize the cross-sectional area of each layer, further reducing suction.

Final Thoughts

Speed doesn’t have to compromise functionality. By pairing the Elegoo Saturn 3 Ultra with Siraya Tech Tenacious Flex, you can produce industrial-grade elastomer parts faster than ever.
