Liqcreate Bio-Med Flex Resin

Liqcreate Bio-Med Flex is a flexible and biocompatible photopolymer resin for 3D printing with a Shore A73 hardness, developed to manufacture elastic parts using DLP, LCD, MSLA and SLA technologies. Its combination of flexibility, elasticity and biocompatible properties makes it a particularly interesting solution for medical and healthcare applications and functional prototypes that require materials capable of deforming without losing functionality.

This flexible resin for 3D printers can be processed on a wide variety of resin 3D printers compatible with 385 and 405 nm wavelengths, provided they allow the use of third-party resins and the adjustment of printing parameters. After correctly applying the washing and post-curing processes recommended by the manufacturer, printed parts exhibit biocompatible properties.

Flexible and biocompatible 3D printing resin

The main advantage of Bio-Med Flex is the combination of flexibility and biocompatibility in a single material. With a Shore A73 hardness, this elastomeric resin for 3D printing enables the production of flexible parts with an elongation at break of approximately 180-250%, depending on the processing conditions.

Its formulation is designed for applications requiring non-cytotoxic, non-sensitizing and non-irritating parts, provided that the complete printing, cleaning and post-curing process is carried out in accordance with the validated processing instructions.

This combination makes Liqcreate Bio-Med Flex a specialized alternative for those looking to buy flexible biocompatible resin for 3D printing and needing to reproduce geometries with elasticity, deformability and properties suitable for technical applications.

Biocompatibility according to ISO 10993

Parts manufactured with Liqcreate Bio-Med Flex and subjected to the recommended washing and post-curing process pass the relevant biocompatibility tests for cytotoxicity according to ISO 10993-5:2009, sensitization according to ISO 10993-10:2021 and irritation according to ISO 10993-23:2021.

The stated biocompatibility applies to correctly processed parts, making it essential to follow the specified parameters and procedures to achieve the material's final properties. When manufacturing regulated medical devices, responsibility for the registration, validation and use of the device lies with the device manufacturer.

Flexible resin compatible with DLP, LCD, MSLA and SLA

Bio-Med Flex is designed to work with different resin 3D printing technologies, including DLP, LCD, MSLA and laser-based systems. It is compatible with equipment operating at 385 nm and 405 nm, provided that the printer allows the adjustment of the parameters required for third-party resins.

This open compatibility considerably expands the possibilities for integration into different additive manufacturing workflows. Exposure settings must be adapted to each printer, as the balance between exposure, curing and flexibility directly affects the surface quality, dimensional accuracy and mechanical performance of the parts.

Mechanical properties for elastic parts

Bio-Med Flex resin provides elastomeric behavior that is particularly suitable for geometries that need to deform during use. It features a tensile strength of 5.0 MPa, an elongation at break of 180-250%, a tear strength of 20-28 kN/m and a Shore A73 hardness after the post-curing process used for the manufacturer's characterization.

These properties make this flexible 3D resin suitable for manufacturing parts where elasticity is more important than rigidity, enabling the development of prototypes and functional components with flexing and recovery capabilities.

Autoclave sterilization and disinfection

A particularly relevant feature of this biocompatible resin for 3D printing is the possibility of disinfecting printed parts with common disinfectants and subjecting them to steam sterilization in an autoclave. The material has been validated for steam sterilization cycles at 121 °C and 134 °C.

Compatibility with sterilization processes expands the possibilities for using printed parts in certain technical and healthcare environments. Before sterilization, parts must have correctly completed the specified cleaning and post-curing processes to ensure the expected material properties.

Applications of Bio-Med Flex

Liqcreate Bio-Med Flex is particularly suitable for medical 3D printing, functional prototyping and manufacturing flexible parts where biocompatibility and elasticity are required. Its elastomeric behavior allows the creation of components with surfaces and geometries capable of undergoing controlled deformation.

The flexible biocompatible resin for 3D printers is particularly interesting for developing models, prototypes and technical components that require a combination of flexibility, elasticity, tear resistance and biocompatibility, always within the validated scope of use and processing conditions.

Processing to obtain biocompatible parts

To obtain the stated biocompatible properties, printing alone is not sufficient. The post-processing stage is an essential part of the final result. Parts must be properly cleaned to remove uncured resin residues, thoroughly dried and subjected to the UV post-curing process specified for Bio-Med Flex.

The manufacturer recommends keeping the resin and printing environment at approximately 20-25 °C to promote stable behavior during manufacturing. In addition, due to the flexible nature of the material, support structures must provide greater stability than is required with rigid resins, especially for large or high-surface-area parts.

A professional solution for medical and technical 3D printing

Liqcreate Bio-Med Flex combines highly sought-after properties for advanced additive manufacturing in a single flexible 3D resin: biocompatibility, elasticity, flexibility, tear resistance and steam sterilization capability. Its compatibility with DLP, LCD, MSLA and SLA technologies allows it to be integrated into different open resin 3D printing platforms.

For applications requiring a flexible biocompatible resin, deformability and disinfection or sterilization processes, Bio-Med Flex offers a specialized solution designed for manufacturing high-value functional parts.
