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

Selecting the right flexible resin depends on your project's needs for hardness, durability, and printing conditions. Consider these key factors to ensure optimal performance.

Shore Hardness

Shore hardness determines how soft or stiff your print will be. A lower A value like 55A offers extreme flexibility and rubber-like feel, while higher values like 90A provide more structural support with moderate bending.

Choose a Shore hardness that matches the physical requirements of your model to ensure it bends without breaking under expected stress.

Elongation at Break

Elongation at break measures how much a printed part can stretch before failing. Resins with higher percentages allow for greater deformation and recovery, essential for parts that undergo repeated stretching or compression.

Look for resins with high elongation ratings to maximize the flexibility and durability of your functional prints.

Impact Resistance

Impact resistance refers to the material's ability to withstand sudden shocks or drops. Resins with enhanced toughness prevent cracking or shattering when models fall or are subjected to dynamic loads.

Prioritize impact-resistant formulations for models that will be handled frequently or used in environments with physical hazards.

Curing Wavelength

Flexible resins are generally optimized for 405nm wavelengths, but some may require specific ranges like 365nm to 405nm. Always check your printer's light source to ensure compatibility and proper curing.

Verify wavelength compatibility with your printer to avoid under-cured parts or excessive printing times.

Shrinkage Rate

Shrinkage occurs as resin cures and hardens. Flexible resins often exhibit low shrinkage to maintain dimensional accuracy, ensuring parts fit together correctly without warping or size distortion.

Select resins with low shrinkage for precise models requiring tight tolerances and accurate assembly.

Odor and VOCs

Flexible resins can emit odors during printing. Low-odor formulations with reduced volatile organic compounds (VOCs) create a safer and more comfortable environment, especially in non-industrial settings.

Opt for low-odor options if you print in shared or ventilated spaces to minimize exposure to chemicals.

Cleaning and Post-Curing

Flexible prints often require careful cleaning and post-curing to avoid stickiness. Ensure the resin works with standard cleaning solvents like isopropyl alcohol and provides a stable surface after curing.

Choose resins that simplify post-processing to save time and ensure a non-tacky finish for your final products.

Compatibility with Printers

Most flexible resins work with LCD, DLP, and SLA printers. However, check compatibility with specific screen types like monochrome or color LCD to maximize print speed and accuracy.

Ensure the resin matches your printer's capabilities to avoid compatibility issues during the printing process.

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

Store flexible resin in a cool, dark place to prevent premature curing. Keep bottles tightly sealed when not in use to avoid air exposure and contamination.

Shake the resin bottle gently before pouring to ensure uniform consistency. Use a dedicated bucket for printing to prevent cross-contamination with other resin types.

Clean printed parts with isopropyl alcohol after printing and follow manufacturer instructions for post-curing. Proper curing ensures the flexible properties and durability of the final print.
