Fast Model Resin - FormLabs

The Fast Model resin is a versatile material from the Formlabs SLA 3D printing range, designed for rapid prototyping and high-throughput applications. As the next-generation evolution of Draft Resin, the Fast Model resin excels in printing speed, offering up to three times faster performance with the Form 4 series printers (over 100 mm per hour).

This makes it an ideal solution for creating initial prototypes to evaluate shape and feel, performing rapid design iterations, and printing large models (under 2 hours) or dental models for thermoforming aligners (a matter of mintues). The Fast Model resin guarantees a low-odor printing experience and produces parts with a matte grey color and a smooth surface finish.

This resin streamlines post-processing, requiring only a 5-minute wash and 5-minute post-cure at room temperature, while still achieving strong mechanical properties. The tensile strength of Fast Model Resin reaches 55 MPa, with a tensile modulus of 2500 MPa, and an elongation at break of 15%. It also boasts a flexural strength of 98 MPa, a flexural modulus of 2600 MPa, an impact strength of 3 kJ/m², and a heat deflection temperature (HDT) of 58 ºC. An optional 15-minute post-cure at 60 ºC using the Form Cure device can improve strength, stiffness, and heat deflection temperature. Details on the Fast Model resin's mechanical properties as well as the recommended washing and curing settings can be found in the Attachments section.

Fast Model Resin is compatible with various printers and accessories from the Formlabs Form 4 ecosystem. It works seamlessly with the Form 4, Form 4B, Form 4L, and Form 4BL printers. The resin is also supported by Form 4 nd Form 4L resin tank, as well as the Form 4 build platform, Form 4 build platform Flex, and Form 4L build platform L, ensuring that users can achieve optimal results regardless of the size or scope of their projects.
