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

Selecting the right flexible resin involves understanding key properties like shore hardness, elongation, and chemical resistance. This guide helps you weigh these factors to match the resin to your specific project needs.

Shore Hardness and Flexibility

Shore hardness indicates how soft or stiff the cured resin feels. Lower values like 55A or 70A mean softer, more rubber-like parts, while higher values like 90A offer tougher, less flexible structures. Choose based on whether you need a soft cushion or a durable grip.

Always check the shore rating before buying to ensure it meets your softness requirements.

Elongation at Break

Elongation measures how much the material can stretch before breaking. High elongation percentages mean the part can bend significantly without cracking, which is vital for moving parts or wearables. Look for values above 100% for flexible applications.

Higher elongation values guarantee better resistance to snapping under stress.

Print Compatibility

Ensure the resin wavelength matches your printer, typically 405nm for modern LCD printers. Some resins are optimized for specific printer types or may require adjusted exposure settings. Always check the compatibility list provided by the manufacturer.

Verify wavelength compatibility to avoid failed prints due to incorrect curing.

Safety and Odor

Flexible resins can emit odors or irritate skin. Look for low-odor formulations and non-irritating certifications. Proper ventilation and protective gear are essential during handling and post-processing to ensure safety.

Prioritize low-odor and certified safe materials for comfortable printing environments.

Chemical Resistance

If your part will be used in environments with chemicals or oils, check for resistance ratings. Flexible resins that resist corrosion or weak acids will last longer in industrial or outdoor settings.

Choose chemically resistant resins for parts exposed to harsh substances.

Curing and Post-Processing

Flexible resins often need longer curing times or specific cleaning solutions to achieve optimal properties. Some may require dual-curing methods or specific UV exposure to reach maximum hardness. Follow manufacturer instructions precisely.

Follow proper curing protocols to ensure the part reaches its intended flexibility and strength.

Color and Aesthetics

Flexible resins come in various colors but are often opaque. Clear versions might yellow over time or show dust easily. If aesthetics matter, consider painting or selecting a color that fits your design vision.

Select colors that match your project goals or plan for post-print painting.

Price and Volume

Price varies based on bottle size and brand. While bulk buys might save money, ensure you have the storage conditions to prevent degradation. Smaller bottles are better for testing before committing to large volumes.

Balance cost and volume to ensure you have enough material without waste.

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

Before printing, shake the resin bottle thoroughly to ensure all components are evenly mixed. Flexible resins can settle over time, so a good shake ensures consistent viscosity and print quality.

Use proper exposure settings based on the manufacturer's recommendations. Over-curing can make parts brittle while under-curing can leave them sticky. Experiment with test prints to find the perfect balance for your printer.

After printing, wash parts with isopropyl alcohol and cure them under UV light. Flexible parts may need slightly longer curing times to ensure they are fully hardened and durable for long-term use.
