Biotough 3Dresyns

Choose your Biotough route

Use the routes below to navigate the collection by hardness level and chemistry family.

• Biocompatible tough resin portfolio for professional manufacturing workflows.
• Improved resistance to cracking versus standard rigid resins.
• Balanced strength and toughness with grade-dependent hardness.
• Consistent printability and dimensional accuracy after post-cure.
• Availability of both monomer-free and monomer-based chemistry routes depending on grade.

Typical use scenarios across the collection

This collection is suitable for workflows where a part must resist handling stress better than a conventional rigid biocompatible resin while preserving reliable dimensional behavior.

• Durable housings: printed shells and enclosures requiring better toughness and reduced cracking risk.
• Brackets, jigs and fixtures: technical parts that benefit from repeated handling and practical robustness.
• Mechanical components: functional prototypes and engineering parts exposed to moderate stress or impact.
• Professional biocompatible prototyping: controlled workflows where biological interaction and mechanical reliability are both relevant.
• Application-driven hardness tuning: selecting D70, D80 or D90 according to the required balance between flexibility, rigidity and toughness.

How to choose the right Biotough grade

Select the most suitable route according to the target Shore D hardness and whether the workflow prioritises a monomer-free or monomer-based chemistry family.

• Need the highest hardness in the range → choose 3Dresyn Biotough D90 MF Monomer Free
• Need an intermediate balance between hardness and toughness → choose a D80 grade
• Need the softer, more compliant route within the family → choose a D70 grade
• Need a monomer-free workflow → prioritise D90 MF, D80 MF or D70 MF
• Need a monomer-based route → evaluate D80 MB or D70 MB

• Prioritise maximum rigidity and hardness → start with D90 MF
• Prioritise middle-ground toughness and hardness → compare D80 MF and D80 MB
• Prioritise lower hardness with tough behavior → compare D70 MF and D70 MB
• Prioritise reduced-hazard / monomer-free positioning → start with the MF grades

Decision tree summary

Use this simplified logic before detailed printer qualification and application validation.

• Need very high hardness and tough behavior → D90 MF
• Need medium hardness with tough performance → D80 MF or D80 MB
• Need lower hardness with improved crack resistance → D70 MF or D70 MB
• Need a monomer-free workflow → use the MF route
• Need final biocompatibility and regulatory suitability → validate the exact grade under the final qualified workflow and intended use

Then confirm the final route under the intended printer, exposure strategy, washing method, post-cure protocol and application-specific compliance requirements.

Shore D90 monomer-free tough biocompatible route

For workflows requiring the highest hardness level within the Biotough collection while maintaining the tough, crack-resistant positioning of the family.

Shore D80 tough biocompatible route

For workflows requiring an intermediate balance between toughness, rigidity and handling performance, with both monomer-based and monomer-free options available.

Shore D70 tough biocompatible route

For workflows requiring the lower-hardness end of the Biotough family while preserving durable part behavior and reduced cracking tendency versus standard rigid grades.

Monomer-free Biotough grades

For workflows that prioritise the monomer-free family while still selecting the most appropriate hardness level for the application.

Monomer-based Biotough grades

For workflows where the monomer-based family is preferred and the final selection is driven mainly by the required hardness level.

A structured tough-biocompatible platform rather than a single-grade page

This collection is clearly structured around three Shore D hardness levels and two chemistry families, allowing selection by mechanical target as well as workflow preference.

• D90 MF covers the highest-hardness route.
• D80 MB and D80 MF cover the intermediate-hardness route.
• D70 MB and D70 MF cover the lower-hardness route.
• MF grades cover the monomer-free route, while MB grades cover the monomer-based route.

The right Biotough grade depends on the final workflow, not only on the product name

Biocompatibility-related testing may be performed under controlled laboratory conditions depending on the formulation and version, and reported results should not be interpreted as intrinsic or unconditional properties of the liquid resin alone.

These materials are structured material systems. Final performance and biological response are workflow-dependent outcomes obtained under reference configurations, not intrinsic constants independent of processing variables.

The regulatory classification, validation and compliance of any final medical device manufactured using these materials remain the sole responsibility of the legal manufacturer of that device in accordance with applicable regulations.
