SainSmart TPU Filament
Best flexible filament for creating durable, rubber-like functional parts.
This filament is the bridge between rigid plastic and rubber, perfect for creating durable, flexible parts like gaskets or protective gear. It demands patience and careful tuning—especially with retraction settings—but the payoff is a high-strength, oil-resistant material that standard PLA simply cannot replicate.
