3D-ADD GrapEK1-MWCNT Bio, biocompatible electrically conductive multi wall carbon nanotubes 3D additive

3D-ADD GrapEK1-MWCNT Bio is an effective electrically and thermally conductive multi wall nanotubes additive designed for manufacturing conductive 3D printing materials.

This conductive additive is supplied in powder form and is intended for custom addition into compatible 3D resins to promote electrical conductivity depending on dosage, resin selection, dispersion quality and printing conditions.

Designed for conductive material development in vat photopolymerization workflows by addition into compatible 3D resins for SLA, DLP and LCD 3D printing systems.

• Electrically conductive 3D printing materials
• Thermally conductive 3D printing materials
• Custom conductive resin formulation development
• Functional conductive printed parts

• Viscosity: mPas at 23°C ± 2°C (ISO 3219)
• Reference thickness for typical achievable values: 250 microns

• Resistivity: <0.1-100 Ω.cm
• Sheet resistance: <0.004-4 kΩ/square
• Conductivity: >1-1000 mS/m

• Conductive multi wall nanotubes additive in powder form
• Excellent compatibility with most 3D resins
• Improved conductivity can be achieved when used with 3Dresyn NSEK Bio
• Dosage can be custom adjusted
• Typical dosages of up to 1.5-2 % by weight are recommended
• Higher dosage increases viscosity significantrly and reduces cured thickness and printable Z layer thickness
• Z layer thickness of <20-40 microns (<0.02-0.04 mm) can be printed with low power printers

• Easy and optimum dispersion in 3D resins with high speed homogenizer mixers at 1500-2000 rpm
• Excessive dosage mayicrease viscosity significasntrly, promote the formation of clusters or clumps, including sea-island or nodular structures, and asymptotic behavior of the percolation network
• More information available in Instructions for Use IFU for conductive resin systems
• Please do not expose 3Dresyns to direct natural or artificial room light to prevent curing
• Guaranteed shelf life: 12 months

• Biocompatible
• Electrically conductive
• Thermally conductive
• Multi wall nanotubes additive

Conductivity of 3D printed parts depends on several variables, such as the percentage of 3D-ADD GrapEK1-MWCNT Bio, the contribution to promote conductivity of the chosen 3D resin, the degree of dispersion of the conductive additive and the printing conditions. When 3D-ADD GrapEK1-MWCNT Bio is added as a functional additive to any 3D resin, conductivity of the resulting product cannot be guaranteed since conductivity depends on both the additive and the chosen 3D resin. Low power 3D printers may exhibit printability limitations at high dosage of 3D-ADD GrapEK1-MWCNT Bio and high Z layers. In such cases reduce Z layer thickness and exposure times accordingly following the Instructions for Use IFU.

This material is supplied as a professional manufacturing additive and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
