Spectrum PLA Electrically Conductive Filament BLACK 1.75mm 0.75kg

Description

Spectrum PLA Electrically Conductive Filament BLACK 1.75mm 0.75kg – Conductive PLA filament with carbon nanotubes

Spectrum PLA Electrically Conductive Filament is a 1.75 mm technical PLA filament developed for applications where basic electrical conductivity is required, together with the easy printability typical of PLA. Spectrum PLA Electrically Conductive Filament is based on a PLA polymer modified with carbon nanotubes (CNT), which significantly reduces surface resistivity and makes it suitable for components that need basic electrical conduction. Spectrum PLA Electrically Conductive Filament is easy to process, low-shrinkage, and printable without a heated chamber, with a matte surface that helps reduce visible layer lines.

Key Benefits at a Glance

• Electrically conductive PLA: Designed for parts where basic electrical conduction is needed.
• Carbon nanotube modified: Spectrum states the PLA base is modified with CNT to significantly reduce surface resistivity.
• Easy to print: Retains typical PLA advantages such as easy processing, low shrinkage, and no need for a heated chamber.
• Matte technical finish: The matte surface helps minimize visible layer lines and gives prints a cleaner look.

Ideal Applications

Spectrum PLA Electrically Conductive Filament is ideal for educational, workshop, and prototyping environments where both functionality and printing simplicity matter. It is a practical choice for printed parts that need basic electrical conductivity while still being easy to manufacture on standard PLA-capable printers.

Why You’ll Love It

Spectrum PLA Electrically Conductive Filament is a useful option when standard PLA is not enough but you still want straightforward printing behavior. Its combination of CNT-based conductivity, matte finish, low shrinkage, and no-heated-chamber printing makes it especially suitable for simple conductive prototypes and functional workshop parts.
