Tough PLA 3D Printer Filament

If you're looking for a 3D printing filament that offers the best of both worlds - easy use and durable - then Protomaker's Tough PLA is the perfect choice for you. Unlike regular PLA, which is known for its ease of use but can be brittle and lack durability, our Tough PLA filament offers significantly improved impact resistance and layer to layer bond strength. This means you can enjoy the convenience of printing with PLA while also benefitting from the durability of more advanced materials. To see the difference for yourself, check out our blog where we compare Tough PLA to Basic PLA.
