⚙️ Recommended Exposure Parameters

⚠️ Elastic Resin Printing Notes

Elastic resin printing parameters differ from standard hard resins. Use longer bottom layer exposure times to ensure adhesion, while avoiding over-exposure which can make the final product too hard and lose elasticity. For first use, start with middle values for test prints.

Printer Model	Screen Type	Bottom Layer Exposure	Normal Layer Exposure	Layer Height
Phrozen Make	Color-LCD	30 ~ 40 sec	8 ~ 12 sec	50 µm
Phrozen Sonic mini	Mono-LCD	20 ~ 30 sec	5 ~ 8 sec	50 µm
Miicraft 125 DLP	DLP	8 ~ 12 sec	1.5 ~ 2.5 sec	50 µm

💡 Elastic Resin Parameter Adjustment Tips:
• Poor adhesion: Increase bottom layer exposure by 5~10 seconds
• Product too hard, losing elasticity: Reduce normal layer exposure by 1~2 seconds
• Unclear details: Try reducing layer height to 25~35 µm
• Post-cure time: Recommend 10~30 minutes (too long will harden the product)

📋 Usage Steps (5 Steps to Complete)

Shake Well

Gently shake the bottle for 30 seconds before use to mix thoroughly

Set Parameters

Set recommended exposure time per printer model, use middle values for first use

Print Complete

Gently remove model after printing, avoid excessive force

IPA Wash

Wash with 95% IPA alcohol for 30~60 seconds to remove residual resin

UV Post-Cure

365~405nm UV light box for 10~30 minutes (avoid over-curing)

⚠️ Important: Post-Cure Time Control

Post-cure time is critical for elastic resins! Over-curing (more than 60 minutes) will cause the product to harden and lose its elastic properties. Start with 10 minutes and gradually adjust based on the elasticity of the finished product.

❓ Frequently Asked Questions

Q: What's the difference between Flex 8A and Flex 25A? Which should I choose?

A: The main difference is hardness and rebound. Flex 8A (Shore 8A) is extremely soft with 700% elongation and gel-like texture, ideal for wearables and medical models requiring extreme softness. Flex 25A (Shore 25A) is slightly firmer with 270~340% elongation and better rebound support, suitable for functional buttons, cushion pads, and wristbands needing elasticity with some support.

Q: Why is post-cure time so important for elastic resins?

A: Post-cure time directly affects the elastic properties of the final product. Insufficient post-cure may leave a sticky surface; excessive post-cure (over 60 minutes) will gradually harden the product, losing elasticity. Start with 10~15 minutes and adjust based on the elasticity of the finished product.

Q: Can Flex 25A be used to make seals?

A: It can be used for prototype testing and low-pressure sealing applications. Shore 25A hardness and 270~340% elongation provide good sealing performance. Note that 3D printed seals may have layer lines; for high-pressure or demanding sealing applications, functional testing is recommended first.

Q: Is elastic resin printing prone to failure? What should I watch out for?

A: Elastic resins require more attention than hard resins. Key points: (1) Ensure sufficient bottom layer exposure for good adhesion; (2) Avoid overly thin structures (minimum wall thickness 1mm recommended); (3) Set supports appropriately to avoid difficulty in removal; (4) Don't print too fast.

Q: Can Flex 25A products contact skin?

A: Fully cured products have a silicone-like feel suitable for wearable device prototypes. Note that photopolymer resin products are not medical-grade materials. For applications with prolonged direct skin contact, conduct skin testing first and ensure complete post-curing.

Q: What is the shelf life of this resin?

A: Stored sealed, away from light, at 15~35°C, the shelf life is 12 months. After opening, use within 6 months for best printing results. Always ensure the cap is tightly sealed after use.

Q: Can Flex 25A be mixed with other QTS resins?

A: Mixing different resin formulas is not recommended as it may affect curing characteristics and final performance. If you need a hardness between two options, contact QTS technical support for professional formula recommendations.

Q: How should waste resin be disposed of?

A: Never pour liquid resin directly down the drain. Fully cure waste resin into solid form before disposing as general recyclable waste. IPA alcohol used for washing also requires proper disposal and should not be poured into drains.
