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

Choosing the right flexible resin depends on your project requirements and printer capabilities. Consider hardness elongation and print speed to find a match.

Shore Hardness

Shore hardness determines the stiffness of the printed part. Lower values like 55A or 70A create soft rubber-like textures while 80A to 90A offer harder resilient feel. Select based on whether you need cushioning or impact resistance.

Check the required hardness for your project to ensure the resin can withstand the expected stress without being too rigid.

Elongation at Break

Elongation indicates how much a part can stretch before breaking. Higher percentages mean better flexibility and resistance to snapping under tension. Look for values above 100% for durable flexible models.

Prioritize resins with high elongation if your models will be bent repeatedly or subjected to dynamic movement.

Print Speed

Flexible resins can have varying viscosity affecting how fast they cure. Some formulations support fast layer printing like 50um in 1.7 seconds which saves time. Faster curing can also reduce warping risks.

If you use a 3D printing farm or need high throughput, select resins optimized for monochrome LCD printers.

Odor and Safety

Resins with low odor and non-irritating formulas provide a safer printing environment. Look for ISO 10993-5 certification to ensure biocompatibility after proper curing. This is important for wearables and consumer products.

Choose products that emphasize low volatile organic compounds to protect your health during extended printing sessions.

Shrinkage Rate

Low shrinkage ensures printed parts retain their designed dimensions after curing. High shrinkage leads to distortion which can ruin precise functional fits. Resins engineered for minimal shrinkage improve accuracy.

Prioritize brands that focus on stability to avoid cracks or warping in your final prints.

Compatibility

Ensure the resin works with your printer type and light wavelength. Most flexible resins support 365-405nm for LCD DLP and SLA printers. Wide compatibility avoids issues with exposure settings.

Check product listings for supported printer models to guarantee smooth printing without hardware restrictions.

Finish and Texture

Some resins cure with a smooth non-sticky surface while others may be tacky. A pleasant touch is vital for wearables and parts handled frequently. High-resolution finishes also look better visually.

Select resins that mention smooth surface finish if aesthetics matter for your end-use product.

Additive Use

Certain tough resins can be mixed with other materials to improve impact resistance. This allows customizing properties without buying new bottles. Adding flexible resins to tough resins enhances durability.

Look for products that offer versatility as additives if you work with multiple resin types.

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

Print at appropriate exposure times based on manufacturer recommendations to avoid overcuring or undercuring. Flexible resins often require longer exposure than standard ones to ensure proper bonding.

Wash prints with isopropyl alcohol to remove uncured resin. Use a brush gently for intricate details to avoid damaging flexible features before curing.

Post-cure prints thoroughly using UV light to achieve full strength and safety. Flexible parts benefit from full post curing to reach stable mechanical properties and reduce tackiness.
