Tough Resin is an advanced photopolymer designed to offer a tensile and flexural strength comparable to the one of injection-molded ABS. It is an engineering-grade material formulated and produced by Formlabs. Thanks to its chemical formulation, it lets you produce robust and impact-resistant parts capable of performing under stress and strain. It gives the model high durability and wear resistance. The final printing results are a great combination of impact resistance, flexibility, elongation and yield strength. Thanks to their toughness, they are able to return to their original form after applying a specific force over a short period.
Formlabs Tough Resin is capable of reproducing a high-level of detail granting high resolution and strength. It delivers smooth surfaces just after printing. It is optimized for use on both Form 3 and Form 2 SLA 3D printers. It is ideal for creating functional parts, prototypes, snap-fit joints, and industrial tools. All parts made with Tough Resin should be post cured for maximizing their mechanical properties. You can also machine them if required.
When printing with Tough Resin, you should add support structures and avoid to print directly on the build platform. Heating the build plate facilitates print removal. Continue reading to learn more about the material.
Tough resin can be used to create rugged functional tools, just like this cool blue wrench.
Tough Resin is characterized by a high level of toughness. This means it is capable of absorbing a certain amount of energy before breaking. Sold in 1L cartridges, it can be printed at either 50 and 100 microns.
It provides a good balance of strength and ductility. Unlike Formlabs Standard Resins, it features a higher elongation and lower stiffness. Tough resin needs to be post-cured to reach its optimal mechanical properties.
When post-cured, Tough resin features the following performance properties:
For additional information, you can refer to the material datasheet available on the Formlabs website.
Tough Resin prints should be washed in isopropyl alcohol (IPA) for a maximum time of 20 minutes. After that time, parts might lose their rigidity and strength. After washing and drying, you can cure them according to the cure time and settings provided by the manufacturer.
The chemical formulation of the Formlabs Tough Resin includes a blue additive, which gives it a transparent blue hue.
For some resins, color availability might change. In case of any questions, please get in touch.
