The Tough 2000 resin is part of the engineering resin family of FormLabs - a set of resins developed to solve the most complex engineering challenges thanks to the wide variety of functional materials.

The Tough 2000 resin is the most resistant and rigid material within the range of Tough and Durable engineering resins from Formlabs. As its name indicates, the 2000 corresponds to the tensile modulus of this material (2000 MPa). The Tough 2000 resin has enhanced mechanical properties, among which the following stand out:

Increase in elongation at break of more than 100%.
Higher flexural strength and flexural modulus of approximately 15%.
Better performance at elevated temperatures.

Properties	Tough 2000	Tough	Improvement (%)
Elongation at break (%)	48	23	109
Tensile Modulus (MPa)	65	57	14
Flexural Modulus (%)	1.9	1.6	19
Flexural Temperature under load at 1.8 MPa (ºC)	53	43	23
Flexural Temperature under load at 0.45 MPa (ºC)	63	47	34

In addition to being less brittle and more rigid and strong than the Tough resin, the Tough 2000 resin simulates the properties of ABS; a material widely used in the industrial sector for its high mechanical properties.

Thanks to its enhanced mechanical properties and good print resolution (supports resolutions of 100 and 50 microns), the Tough 2000 resin is suitable for a wide variety of applications in fields such as engineering. It is an ideal material for the manufacturing of wear-resistant prototypes, mechanical connectors, housings, etc.

Below, a series of usage tips are cited that must be taken into account at all times with the use of FormLabs resins:

Change cartridge

Changing the resin cartridge of the FormLabs printers is very simple, just close the top cap of the ventilation duct (vent) and remove the cartridge by holding it by the handle it has. Then the other is inserted and the vent plug is opened in case an impression is to be started. To avoid drips through the 3D printer, this process must always be carried out with the resin tank mounted.

After finishing each impression the vent plug must be closed so that the resin maintains its properties. In addition, if you don't use the printer for some time, you should keep the cartridge in its original box to keep the properties of the resin intact.

Resin tank

Each type of resin must have its resin tank, which must be changed after using 2L of resin. FormLabs has developed a more powerful tank, the Resin Tank LT, which has a life up to 20 times longer than the standard tank.

To protect and store the excess resin in the tank after each printing, FormLabs supplies a lid that ensures a perfect closure. Once the tank is closed, it is recommended to store it (with resin and lid) in the original box so that the resin doesn't lose its properties when exposed to UV rays for a long time. Another point to keep in mind is that the tanks can't be cleaned with any cleaning product or similar (for example, isopopyl alcohol), since they lose certain qualities that can cause continuous failed impressions.

Failed printing

When an error occurs in printing may be because solid parts of a previous printing have fallen to the resin tank. In this case, a spatula at 45° must be passed through the printing tank, gathering all the solid parts in a corner and removing them. To ensure that the tank resin doesn't contain any solid parts, the resin should be cast with a 190 μm paper filter. Once cast, it is put back into the tank and it is ready to be used again.

Isopropyl alcohol

Isopropyl alcohol is the key to the washing and post-processing of parts and you should know when it is time to change it. In the Finish Kit the moment to change it's when the IPA (Isopropyl Alcohol) is so saturated with resin particles, that after washing the pieces are still sticky. At that point you must remove all the liquid, clean the container well and throw new IPA, but never fill in on the previous one.

In the Form Wash, the wash center itself indicates through its screen when it is time to change the isopropyl alcohol.
