PLA/CNT Conductive

For projects needing reliable ESD protection without complex materials, ABC3D’s PLA/CNT Conductive Filament is the perfect solution. Specifically, this filament blends easy-to-print, eco-friendly PLA with the advanced electrical properties of Carbon Nanotubes (CNTs). By creating a conductive network within the PLA matrix, it maintains uniform resistivity. Consequently, it’s an ideal choice for sensitive electronics and low-voltage uses, a concept supported by research like that of Mahmoodi et al., 2012.

To match your specific application, our PLA/CNT Conductive Filament is available in three distinct grades:

1. Antistatic – offering a volume resistivity of 10E8 to 10E10 ohm cm.
2. Electrostatic Discharge Grade (ESD) – featuring a volume resistivity of 10E4 to 10E6 ohm cm.
3. Conductive EMI/RFI Shielding – possessing a volume resistivity of 10E0 to 10E2 ohm cm.

Creating functional, conductive parts with minimal hassle makes this filament an excellent choice. Since it prints with the same ease as standard PLA, for instance, it’s perfect for rapidly prototyping electronic jigs, custom touch sensors, and various educational models. This accessibility subsequently makes our PLA/CNT Conductive Filament popular among makers, researchers, and engineers. Additionally, the final printed objects feature a clean matte finish, providing a professional look straight from the print bed.

Printer Specifications

Nozzle Temperature: 210°C – 230°C

Bed Temperature: 50°C – 65°C

Nozzle Type: Hardened steel (0.4mm or larger) is strongly recommended. The filament is abrasive and will wear down standard brass nozzles.

Print Speed: 40-60 mm/s

Bed Adhesion: A heated glass bed (60°C) with a layer of PEI or blue painter’s tape is recommended.

Filament Drying: Yes. The filament is hygroscopic (absorbs moisture). It’s recommended to dry it in a filament dryer at 50°C for 4-6 hours before printing for best results.

Quality
All our filaments are made with 5-Axis laser-controlled precision, providing the highest class of products for the 3D printing industry.

Frequently Asked Questions

1. Is this filament abrasive? Will it destroy my nozzle?

Yes, this filament is considered abrasive due to the Carbon Nanotube (CNT) content. Consequently, it will wear down a standard brass nozzle quickly. We strongly recommend using a hardened steel, ruby-tipped, or other abrasive-resistant nozzle for printing.

2. Can I use this to print a circuit board or power a device?

It depends. This filament is designed for static dissipation (ESD) and shielding (EMI), not for high-power electrical transmission. While it is conductive, it still has resistance. Therefore, it is excellent for low-voltage applications like capacitive touch sensors or simple LED circuits, but it cannot replace copper wires for household power.

3. How is this different from “Carbon Fiber” filament?

Carbon Fiber filament uses chopped carbon fibers primarily for structural reinforcement—to make parts stronger and stiffer. This PLA/CNT filament, however, uses Carbon Nanotubes primarily for electrical conductivity. Its main purpose is ESD and EMI protection.

4. Do I need to dry this filament?

Yes. The base material is PLA, which absorbs moisture from the air. To prevent stringing, popping, and poor layer adhesion, we recommend drying the spool at 50°C for 4-6 hours before printing, especially if it has been left out.
