Antimicrobial additives

Choose your antimicrobial route

Use the routes below to navigate the collection by copper-based formulation strategy or microorganism growth inhibition support logic.

• Antimicrobial functionality concepts for professional resin workflows.
• Additive-driven support for hygiene-focused parts and handling strategies.
• Copper-based functional resin routes for compatible SLA, DLP, LCD and selected Inkjet systems.
• Microorganism growth inhibition support for liquid resin storage and bulk handling workflows.
• Grade-dependent route selection according to concentration, carrier system, dosage and application logic.

Typical use scenarios across the collection

This collection is suitable for workflows where hygiene management, contamination-control logic or copper-containing functional formulations are part of the technical objective.

• Healthcare-oriented prototypes: concept parts where hygiene-focused material strategies are being evaluated.
• Touch surfaces: functional surfaces where copper incorporation or contamination-control logic is relevant.
• Lab tools and fixtures: professional-use parts in controlled technical environments.
• Bulk resin storage workflows: reducing the risk of microorganism growth during storage and handling under controlled conditions.
• Antimicrobial concept validation: formulation screening before workflow-specific validation and regulatory assessment.

How to choose the right antimicrobial route

Select the most suitable route according to whether the main objective is copper incorporation into the printed part or supplementary microorganism growth control in stored liquid resin systems.

• Need the highest copper concentration in a paste route → choose 3D-ADD CuVK1
• Need a cost-effective copper route with liquid-paste handling → choose 3D-ADD CuVK2
• Need a concentrated copper route with lower addition level → choose 3D-ADD CuVK2C
• Need supplementary microorganism growth control in stored liquid resins → choose 3D-ADD MGI1
• Need the same contamination-control logic at ultra-high concentration → choose 3D-ADD MGI-UHC1

• Prioritise copper loading and metallic functional route selection → start with the CuVK grades
• Prioritise contamination-risk reduction during liquid resin storage → start with the MGI grades
• Prioritise lower dosage through higher concentration → compare CuVK2C and MGI-UHC1

Decision tree summary

Use this simplified logic before detailed formulation and validation work.

• Need copper-containing printed parts → select a CuVK grade
• Need supplementary microorganism growth inhibition in liquid resin workflows → select an MGI grade
• Need higher concentration to reduce the additive percentage → move to CuVK2C or MGI-UHC1
• Need final functional claims on printed parts → validate concentration, compatibility, process conditions and regulatory framework in the final workflow

Then confirm the final route under the intended resin family, additive loading, curing conditions, storage protocol and application-specific validation plan.

Copper-based antimicrobial additives for functional resin development

For workflows requiring copper incorporation into compatible photopolymer systems before printing.

• CuVK1: super high pure copper metal content paste, brownish copper color, recommended addition dosage ≤ 1.7%.
• CuVK2: blue liquid paste, up to 20% copper content, hydrophobic carrier system, recommended dosage ≤ 5% by weight relative to the base resin.
• CuVK2C: blue viscous paste, up to 30% copper content, hydrophobic carrier system, recommended dosage ≤ 3.3% by weight relative to the base resin.
• CuVK2 and CuVK2C may benefit from improved dispersion stability when used with anti-sedimentation support.
• All copper grades are positioned for compatible SLA, DLP, LCD and selected Inkjet resin workflows.

Supplementary contamination-control additives for liquid resin workflows

For workflows requiring supplementary microorganism growth control in stored liquid 3D printing resins under controlled professional conditions.

• MGI1: recommended concentration 2–4% (v/v) added to compatible liquid 3D resins.
• MGI-UHC1: ultra high concentration route with recommended concentration 1–2% (v/v).
• Designed to support resin hygiene management and contamination-risk reduction in bulk resin handling workflows.
• Professional-use-only positioning for laboratory and industrial environments.
• These additives are supportive processing additives and do not replace validated sterilization, aseptic processing or regulated disinfection procedures.

A focused antimicrobial platform rather than a generic additives page

This collection is compact and clearly structured around two complementary routes: copper-containing additive systems and microorganism growth inhibitor additive systems.

• CuVK1, CuVK2 and CuVK2C cover the copper-functional route.
• MGI1 and MGI-UHC1 cover the contamination-control support route for liquid resins.
• Together, they support hygiene-focused functional formulation strategies across different concentration, handling and workflow requirements.

The right antimicrobial route depends on the function target and compliance framework

These materials are most useful when the objective is defined first: copper-containing printed parts, contamination-risk reduction during resin storage, lower-dose concentrated additive routes or hygiene-focused concept validation.

In practice, the correct path is to define the intended use first, then validate the chosen route under the intended resin family, additive concentration, storage protocol, processing conditions and applicable regulatory requirements.
