Tough precision model material is a thermoplastic engineered for durable, strong and dimensionally accurate 3D printed prototypes and fixtures. With up to 2X the impact-strength of ABS and similar tensile and flexural strength properties, MakerBot Tough Material gives high durability and toughness. Extensively-tested for the highest reliability and measurably accurate parts. Smart Spool provides valuable information including material type, colour and amount remaining via an RFID chip directly to MakerBot Print, while a desiccant in the spool maintains a low moisture level inside the drawer bay.
