Spectrum PLA Electrically Conductive

The electrically conductive PLA filament from Spectrum represents a new generation of technical materials for 3D printing, designed to deliver true electrical performance, dimensional accuracy, and unmatched ease of printing. Thanks to its PLA base modified with carbon nanotubes (CNT), this material significantly reduces surface resistivity, making it possible to create parts with functional electrical properties directly from the 3D printer.

High-conductivity technical 3D filament with maximum stability

This conductive filament for FDM and FFF 3D printing combines the versatility of PLA with advanced carbon nanotube technology, ensuring an easy printing process without shrinkage or the need for a heated chamber. Its excellent dimensional stability and trouble-free processing make it an ideal choice for prototyping laboratories, educational environments, engineering projects, and industrial applications that require safe and precise conductive materials.

The result is parts with a professional matte texture, minimizing visible layer lines and providing a technical, uniform appearance — perfect for functional components, antistatic housings, connectors, sensors, and electronic prototypes.

Proven electrical properties and technical performance

Volume resistivity tests confirm the excellent performance of the conductive PLA with carbon nanotubes. Under a voltage of 10 V and extrusion temperatures of 210°C, 220°C, and 230°C, the obtained values were 120 Ω·m, 103 Ω·m, and as low as 97 Ω·m, respectively. These results demonstrate that a higher printing temperature improves electrical conductivity thanks to the optimized dispersion of carbon nanotubes within the polymer structure. This translates into more efficient and reliable parts for projects where electrical functionality is essential.

Advanced material for printed electronics and professional prototyping

The electrically conductive PLA offers superior technical performance while maintaining the ease of printing characteristic of PLA. Thanks to its carbon nanotube formulation, this material enables the development of functional electronic devices, interactive prototypes, antistatic components, and experimental circuit models — without the need for complex setups or industrial equipment.

Its slight abrasiveness, due to the nanotube content, requires the use of hardened steel or ruby nozzles to maintain precision and extend extruder lifespan, ensuring high-quality printing at all times.

The conductive filament that revolutionizes professional 3D printing

The conductive PLA filament redefines the standard in functional 3D printing materials, combining electrical conductivity, structural strength, and aesthetic finish. Compatible with most FDM 3D printers, it allows professional results in every project — from technical prototypes to advanced electronic applications.

Its stable behavior, current-carrying capability, and deformation-free printing position it as one of the most powerful and versatile options on the market for those seeking high-performance conductive materials for professional 3D printing.

The PLA with carbon nanotubes offers a unique combination of electrical properties, dimensional stability, printability, and high-quality finish, ideal for engineering, technical education, research, printed electronics, and functional prototype development. This filament takes professional 3D printing to a new level of innovation, opening the door to smart and functional solutions within the additive manufacturing ecosystem.
