3D-ADD AA1 Adhesive Additive for adhesion on difficult surfaces

3D-ADD AA1 is a hydrophilic adhesion-promoting additive designed for use in photopolymer resin systems for SLA, DLP and LCD 3D printing technologies.

The material is formulated to enhance adhesion on challenging substrates such as metals, glass and engineering plastics, improving first-layer bonding and reducing print failures related to poor surface interaction.

This low-viscosity additive enables easy incorporation into existing resin systems without significantly altering flow behavior or processing conditions.

Designed for incorporation into vat photopolymerization systems (SLA, DLP and LCD) in professional and industrial environments requiring improved adhesion to build platforms and functional substrates.

• Improved adhesion on metal and glass build platforms
• Printing on difficult or low-reactivity surfaces
• General-purpose adhesion enhancement in standard 3D resins
• Process stabilization in challenging printing conditions

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
• Appearance: transparent liquid
• Viscosity: <10 cps (very low viscosity)
• Very low viscosity for easy blending and homogeneous dispersion
• Form: clear liquid additive

• Promotes strong adhesion to metals, glass and plastics
• Improves wetting and interfacial interaction
• Reduces delamination and first-layer failure
• Maintains rigid, non-flexible material behavior

• Recommended loading: 1–2 wt%
• Add directly to the base resin and mix thoroughly
• Suitable for most commercial SLA, DLP and LCD resin systems

• Compatible with SLA, DLP and LCD printing technologies
• Does not significantly alter standard printing workflows
• Suitable for use in open and material-adaptable systems

• Organo-tin free formulation
• Hydrophilic functional additive
• Corrosive liquid — handle according to safety guidelines

Performance depends on base resin composition, printer type, exposure conditions and surface characteristics. Adhesion improvement must be validated under the specific printing conditions and substrates used.

This product is supplied as a formulation additive for professional use in photopolymer engineering and additive manufacturing workflows. It is not a standalone printable material. Final performance and suitability must be validated by the user according to the intended application.

This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
