Join this exploration into the promising yet intricate universe of conductive 3D filaments, where each layer unravels new potentials for technology and design.
Conductivity Properties of PLA Filament
In the realm of 3D printing materials, the conductivity properties of PLA filament play a crucial role in determining its suitability for electrical applications. PLA filament is inherently non-conductive with a resistivity of 10 Ωm, making it an effective electrical insulator in its solid state.
However, when heated above its transformation temperature of 70°C, PLA softens, becoming conductive and unsuitable for insulation purposes. This characteristic makes PLA filament safe for low-voltage, low-heat applications but not recommended for scenarios involving high temperatures.
Additionally, PLA is biodegradable and serves as an excellent insulator up to 70°C, comparable to LDPE, making it a versatile option for various 3D printing projects with specific electrical requirements.
