Formlabs BioMed Elastic 50A Resin Cartridge for Form 4, 1L

Create exceptionally soft and flexible biocompatible parts with the Formlabs BioMed Elastic 50A Resin Cartridge for Form 4, 1L. This transparent medical-grade elastomer features a Shore 50A hardness, making it the ideal material for producing comfortable, patient-specific devices and realistic soft-tissue anatomical models. Manufactured in FDA-registered facilities with ISO 13485 certification and USP Class VI compliance, this soft biocompatible resin enables medical professionals to innovate with confidence — replacing slow and costly moulding workflows.

Print realistic, biocompatible soft parts

Designed for patient comfort

Leverage this highly elastic material to produce mass-customised medical devices that offer an excellent feel and comfort for prolonged skin contact. Eliminate the need for moulds by printing flexible, patient-specific parts directly in 3D — delivering superior fit and tactile quality.

Realistic models for surgical planning

Provide surgeons with tangible, realistic models for preoperative planning and reference. BioMed Elastic 50A Resin produces soft-tissue models — including organs, muscles, and complex vasculature — that mimic the feel and biomechanics of human tissue, enhancing preparation and training for complex procedures.

Functional transparency

The material's transparent nature allows a clear view of internal structures. This is invaluable for creating models where visualisation of tool or fluid flow within the part is critical for design validation and functional testing.

Certified for medical-grade applications

Print with the confidence of a material manufactured to the highest quality standards. This resin is produced in strict compliance with ISO 13485 and holds USP Class VI certification, making it suitable for applications requiring prolonged skin contact (>30 days) and short-term contact with mucous membranes (<24 hours).

Key applications in advanced healthcare

Print soft, elastic, and biocompatible parts directly in 3D, significantly reducing production time and costs. BioMed Elastic 50A Resin is ideal for:

• Comfortable medical devices requiring prolonged skin contact, such as wearable technology and patient-specific padding.
• Realistic soft-tissue models for surgical planning and education, including organs, muscles, and complex vascular networks.

*The final device manufacturer is responsible for validating the biocompatibility and performance of all printed parts for their specific application and intended use. Formlabs provides comprehensive biocompatibility and sterilisation data to support this process.

Material properties

• Shore A Hardness: 50A
• Ultimate Tensile Strength: 2.3 MPa
• Stress at 50% Elongation: 1 MPa
• Stress at 100% Elongation: 1.3 MPa
• Elongation at Break: 150%

Essential post-processing for biocompatibility

To ensure parts meet certified safety standards and achieve their final mechanical properties, a complete and validated post-processing workflow is mandatory. This includes removing all residual resin through washing and performing post-curing in accordance with the official instructions for use. Please refer to the manufacturing guide for detailed protocols.
