Buying Guide – How to Choose the Best Flexible Resin for 3D Printing

Selecting the right flexible resin depends on factors like hardness, print speed, and intended use. Understanding these elements helps you avoid brittle prints and achieve the durability your projects need.

Shore Hardness Level

Shore hardness determines how soft or rigid your print feels. Lower values like 55A or 70A offer softer rubber-like parts, while higher values like 80A or 90A provide more structure.

Choose based on whether you need shock absorption or structural integrity. For soft grips go lower, for tough prototypes go higher.

Elongation at Break

Elongation measures how much the material can stretch before breaking. High elongation means better resilience against bending and impact without snapping.

Look for ratings above 100% for flexible parts. This ensures your models can withstand repeated stress cycles.

Print Speed and Curing

Some flexible resins cure faster than others, affecting production speed. Fast-curing resins reduce electricity costs and time on the printer bed.

Check layer time compatibility with your printer. Faster curing improves productivity especially for large batches.

Impact Resistance

Impact resistance refers to the material ability to absorb energy from sudden forces. Resins with high impact resistance are less likely to crack when dropped.

Prioritize this if your parts face physical use. Good impact resistance ensures long-term durability.

Compatibility with Printer

Most resins work with 405nm wavelength printers but always verify. Some need specific LCD or DLP setups to cure correctly.

Ensure your printer supports the resin wavelength to avoid curing issues. Compatibility saves wasted material and time.

Odor and Safety

Flexible resins can emit strong odors during printing. Low-odor formulations create a more comfortable working environment.

Look for ISO certifications for safety. Proper ventilation remains important even with low-odor resins.

Shrinkage and Accuracy

Shrinkage occurs during curing and can distort part dimensions. Low shrinkage ensures your prints retain accurate shapes.

Choose resins with proven low shrinkage rates. This maintains precision for functional prototypes.

Usage and Application

Consider where your print will be used. Wearables need skin-friendly finishes while tools need high toughness.

Match the resin to your specific use case. This ensures performance matches expectations.

How to Use and Care for Your Flexible Resin for 3D Printing

Always shake the resin bottle gently before pouring to ensure consistent mixing. Avoid air bubbles by pouring slowly and keeping the resin in a cool place.

Use protective gear like gloves and masks during printing. Flexible resins are uncured chemicals until exposed to UV light.

Clean prints with isopropyl alcohol and cure them under UV light for full hardness. Proper curing ensures the final flexible properties.
