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

Selecting the right flexible resin requires understanding key factors like hardness, elongation, and printer compatibility.

Shore Hardness

Shore hardness determines how soft or hard the printed part feels. Lower numbers like 55A indicate very soft elastic materials while higher numbers like 90A are stiffer. Choose based on whether you need a soft grip or a rigid flexible part.

For rubber-like feels select lower shore values. For tougher parts choose higher values.

Elongation at Break

Elongation measures how much the material can stretch before breaking. Higher percentages mean the part can bend more without snapping. Look for resins with elongation over 100% for true flexibility.

Higher elongation ensures better durability under stress.

Impact Resistance

Impact resistance indicates how well the part withstands sudden drops or shocks. Flexible resins should recover from impacts without cracking. Check product details for resistance claims to avoid brittle failures.

Strong impact resistance prevents broken models during handling.

Printer Compatibility

Ensure the resin matches your printer type. Most flexible resins work with 405nm LCD DLP or SLA printers. Verify the wavelength and UV requirements before purchasing to avoid curing issues.

Match wavelength requirements for successful curing.

Post-Processing Needs

Some flexible resins require special cleaning or curing. Standard resins often clean with isopropyl alcohol. Others may need specific post-cure times to achieve full flexibility.

Check cleaning and curing steps to save time.

Shrinkage Rate

Shrinkage affects the final size and accuracy of your print. Low shrinkage ensures precise dimensions. High shrinkage can warp flexible parts making them less accurate for prototypes.

Low shrinkage maintains dimensional accuracy.

Odor and Safety

Flexible resins can have strong odors or volatile compounds. Look for low-odor options if working in enclosed spaces. Ensure proper ventilation to maintain a comfortable environment.

Low odor formulas improve workspace comfort.

Additive Potential

Some flexible resins can be mixed with standard resins to add toughness. Check if the product supports blending to modify properties. This allows customization of print strength and flexibility.

Additives offer flexibility in customizing material properties.

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

Shake the resin bottle thoroughly before pouring to ensure homogenous mixing. Pour into your tank carefully to avoid spills on the printer screen.

After printing clean the model with isopropyl alcohol or ethanol to remove uncured resin. Allow it to dry completely before curing under UV light.

Cure the model fully for at least 10 to 20 minutes to maximize flexibility and strength. Store unused resin in a cool dark place to prevent premature curing.
