Buying Guide – How to Choose the Best Flexible Resin for 3D Printing
Choosing the right flexible resin requires understanding hardness elongation and application needs.
Shore Hardness
Shore hardness defines how soft or hard the cured part feels. Options range from 55A for soft rubber to 90A for tougher materials.
Select lower hardness for wearables and higher for structural impact parts.
Elongation at Break
Elongation at break shows how much a part can stretch before failing. Look for values over 100 percent for flexibility.
Higher elongation ensures parts recover after stress without permanent deformation.
Impact Resistance
Impact resistance determines how well a printed object survives drops. This is critical for functional prototypes and tooling.
Choose resins with high impact ratings for durable end-use products.
Printer Compatibility
Ensure the resin works with your specific LCD DLP or SLA printer wavelength. Most support 365 to 405nm UV light.
Compatibility prevents print failures and ensures consistent curing performance.
Post-Processing Needs
Flexible resins often require specific cleaning and curing methods to avoid stickiness. Some need special alcohol or UV steps.
Check cleaning requirements to avoid wasted time and material during finishing.
Odor and Safety
Low-odor formulations improve comfort during long printing sessions. Look for ISO certified materials for skin safety on wearables.
Prioritize low VOC resins for better air quality in your workspace.
Volume and Pricing
Flexible resins come in sizes from 500g to 1kg. Larger volumes reduce cost per gram for production.
Balance size against print frequency to avoid material degradation from storage.
Additive Potential
Some flexible resins act as additives to boost toughness in standard mixes. This offers a cost-effective way to adjust properties.
Test small batches when blending resins to maintain print consistency.
How to Use and Care for Your Flexible Resin for 3D Printing
Stir the resin bottle gently before use to ensure consistent viscosity without introducing bubbles. Warm the bottle in a water bath if it feels too thick for printing.
Print at a slower speed than standard resins to ensure proper layer adhesion and flexibility. Keep the build plate clean and level to avoid peeling during printing.
Clean prints immediately with isopropyl alcohol and cure fully under UV light to achieve maximum hardness. Store unused resin in a cool dark place to prevent premature curing.
Frequently Asked Questions
