Resin Grey Pro is ideal for versatile prototypes, maintaining good mechanical properties, but without compromising precision and surface finish. It should be noted the moderate elongation and low deformation it offers, being an ideal material for modeling, prototypes of injection molded products, masters of molds for plastics or silicones and templates and accessories for manufacturing.

Propiedades	Grey Pro Resin	Rigid Resin	Standard Resin
Flexural Modulus	2.0	3.7	2.2
Tensile Modulus	2.6	4.1	2.8
Elongation	13.0 %	5.6 %	6.2 %

In particular, Resin Grey Pro is the most recommended resin for the manufacture of functional prototypes that will be used repetitively.

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.

Vent plug FormLabs

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.

FormLabs Resin Tank LT

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.
