UPDATE: MakerBot Tough filament is now available in four colors! With 2X the impact strength of ABS, we used it to explore some new advanced applications—check it out here. More and more companies are investing in desktop 3D printers as their preferred tool for prototyping. And in many cases, they are replacing more expensive industrial 3D printers. Used most often for the early phases of concept modeling, desktop 3D printers allow engineers and designers to accelerate the design process and produce more prototypes at a lower cost. At MakerBot, one of our fundamental goals is to streamline this process and offer solutions that extend what’s possible with a desktop 3D printer. We took a major step in this direction with our newly launched MakerBot Tough filament. It enables designers and engineers to go beyond concept modeling and create durable, high-impact strength prototypes and fixtures. It’s a resilient and strong plastic that mimics or even outperforms many of the mechanical properties of ABS while offering the reliability and quality of PLA. As the graph above shows, under a tensile load, MakerBot Tough filament will deform elastically and return to its original shape before hitting peak strength. Beyond this peak, Tough filament will exhibit a very long plastic deformation range before break that outperforms ABS. In contrast, typical PLA will simply fracture. These mechanical properties make MakerBot Tough filament ideal for prototyping many functional features such as living hinges, snap fits, interlocking parts, and threaded features.
