Biotough MB 3Dresyns: safe and tough Monomer Based MB resins with Shore D70-D90

Choose your Biotough MB route

Use the routes below to navigate the collection by hardness level and final part behavior.

• Safe monomer-based tough resin platform for professional printing workflows.
• High toughness and reduced fragility versus many conventional commercial resins.
• High flexural strength positioning for functional engineering and biomedical parts.
• Biocompatible route with strong printability and grade-dependent hardness.
• Availability of standard grades and ULWA logic for lower water absorption positioning depending on version.

Typical use scenarios across the collection

This collection is suitable for workflows where a part must combine practical toughness, good handling safety and reliable dimensional behavior under professional printing conditions.

• Functional engineering parts: technical printed components requiring stronger and tougher mechanical behavior.
• Biomedical and educational workflows: safe monomer-based grades for controlled professional-use environments.
• Food-contact and toy-related prototyping: application-driven development where safer handling positioning matters.
• Jigs, fixtures and housings: durable parts requiring reduced cracking risk and better robustness than many standard resins.
• Hardness-driven selection: choosing D80 or D70 according to the final balance between rigidity and compliance.

How to choose the right Biotough MB grade

Select the most suitable grade according to the target Shore D hardness and the intended mechanical feel of the final part.

• Need the harder monomer-based route in this collection → choose 3Dresyn Biotough D80 MB Monomer Based
• Need the softer and slightly more compliant monomer-based route → choose 3Dresyn Biotough D70 MB Monomer Based
• Need strong toughness with safe monomer-based positioning → compare D80 MB and D70 MB against the final application stress profile
• Need lower water absorption behavior depending on version → validate the available ULWA option or specific supplied version

• Prioritise higher rigidity and hardness → start with D80 MB
• Prioritise lower hardness with tough behavior → start with D70 MB
• Prioritise handling safety with monomer-based chemistry → compare both MB grades under the final qualified process

Decision tree summary

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

• Need the harder monomer-based route → D80 MB
• Need the softer monomer-based route → D70 MB
• Need final biocompatibility and functional suitability → validate the selected grade under the exact printer, washing and post-curing workflow
• Need application-specific compliance → confirm the final route against the intended use and legal manufacturer requirements

Then confirm the final route under the intended printer technology, exposure strategy, washing protocol, post-cure conditions and application-specific qualification workflow.

Shore D80 monomer-based tough biocompatible grade

For workflows requiring the harder option in the Biotough MB collection while maintaining strong toughness and safe monomer-based positioning.

• Monomer-based tough biocompatible route.
• Shore D80 positioning for higher hardness within this MB collection.
• Strong mechanical performance and reduced fragility versus many standard resins.
• Suitable for functional engineering and biomedical material workflows under controlled conditions.
• Compatible with SLA, DLP and LCD/MSLA vat photopolymerization workflows.

Shore D70 monomer-based tough biocompatible grade

For workflows requiring the softer option in the Biotough MB collection while preserving durable part behavior and strong toughness.

• Monomer-based tough biocompatible route.
• Shore D70 positioning for lower hardness and more compliant part response than D80 MB.
• Strong toughness for printed parts requiring durable handling behavior.
• Suitable for functional prototypes, technical parts and controlled biomedical workflows.
• Compatible with SLA, DLP and LCD/MSLA vat photopolymerization workflows.

A focused monomer-based tough-biocompatible platform

This collection is compact and clearly structured around two Shore D hardness levels within the Biotough monomer-based family.

• D80 MB covers the harder route.
• D70 MB covers the softer route.
• Together, they support application-driven selection across higher-rigidity or lower-hardness tough part requirements.

The right Biotough MB grade depends on the final workflow, not only on the nominal hardness

These materials are formulation systems whose final performance is workflow-dependent. Mechanical behavior, dimensional outcomes and biological interaction depend on the complete manufacturing sequence rather than on the liquid resin alone.

In practice, the correct path is to define the final application first, then validate the selected MB grade under the exact printer, exposure settings, washing method, post-curing protocol and intended-use requirements.

The regulatory classification and compliance of any final product manufactured with these materials remain the responsibility of the legal manufacturer of that product.
