Solvent-resistant 3D printing filaments are a family of filaments that are distinguished by their excellent chemical stability, meaning that they are not easily dissolved by most solvents, such as limonene, acetone or grease. Whilst no 3D printing plastic is entirely solvent resistant, the plastics with the solvent-resistant superpower will be resistant to most solvents, they may still be dissolved by strong acids or bases though. Solvent-resistant filaments are essentially the opposite of soluble filaments.

Some plastics are inherently solvent-resistant due to their excellent chemical stability. Polycarbonate and some types of Nylon are commonly used solvent-resistant plastics.

Solvent-resistant filaments can be used for a wide variety of applications that require contact with solvents. Always check the Technical Data Sheet for more information about the chemical stability of a specific filament.
