    Grey Pro Resin

    Resin Gray 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.

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

    Requires Resin Tank LT.

    Resina Rígida (Rigid Resin)

    The Rigid Resin is a resin highly reinforced with glass, giving it a high rigidity and a completely smooth or polished finish. Thanks to the resistance of the glass this material is the one that has a higher impact resistance module of the range of Engineering Resins. It's also resistant to temporary deformation and allows to print thin-walled parts, but at the same time resistant.

    The Rigid Resin is ideal for printing turbines or fan blades, templates, accessories or tools, air passage collectors and housings to house electrical elements.

    Requires Resin Tank LT.

    Durable Resin

    Durable Resin is the ideal material for applications that require minimal friction between surfaces.

    Elongation and Impact Resistance IZOD

    Its large elongation, its high impact resistance (the largest of all engineering materials) and a really striking, smooth and shiny finish, allows parts to be made for a wide variety of applications such as consumables, bushings and bearings, parts with adjustments under pressure or flexible elements.

    Tough Resin

    The high-strength resin called Tough Resin is perfect for creating resistant parts. This resin offers a balance between resistance and compliance. Thanks to the high resistance to stresses and deformations during short time intervals, this material is ideal for parts that need to return to their original shape after applying a high voltage on them.

    With the Tough Resin you can print all kinds of prototypes, from the simplest, to those that are made up of many pieces or that need a high mechanical resistance.

    Resina Tough 1500

    The Tough 1500 resin is the most resilient material within the family of specific resins for the engineering field of the Formlabs company, so it is worth highlighting its ability to recover its original shape after ever being a bending force.

    FormLabs' range of Engineering resins include Durable Resin and Tough Resin. Tough 1500 resin has been created in response to the search for a rigid and flexible material, resistant and with high resistance to impact.

    When comparing Tough 1500 resin with Durable Resin and Tough Resin, we can see that it shares a series of characteristics with them:

    Image 10: Table of mechanical properties for Durable resin, Tough and Tough 1500. Source: FormLabs.

    The properties of Tough 1500 resin are similar to those of polypropylene (PP), a thermoplastic polymer that has high impact resistance and rigidity; and that it is widely used in the Industrial sector.

    Thanks to its mechanical properties and good print resolution (supports 100 and 50 micron resolutions), Tough 1500 resin is suitable for manufacturing rigid parts with high impact resistance; that after bending they can return to their original state quickly even after repeated use. It is very useful in the manufacture of prototypes and functional assemblies, hinges, guides, fixings, etc.

    This resin requires LT resin tank.

    Flexible Resin

    The Flexible Resin is used to print flexible parts, with the need to be bent or compressed for the correct operation of the model. It has a Shore hardness of 80A, which gives a soft and pleasant touch to the pieces.

    Flexible Resin Elongation and Tensile Modulus

    This hardness and finish are very similar to those of the soles of shoes or tires. Thanks to its low traction module and high elongation, this material is suitable for printing shock absorbers, packaging, flexible or ergonomic parts.

    Elastic Resin

    Elastic Resin is a soft material with a Shore 50A ideal for replacing prototypes and parts that are normally produced with silicone. With the use of this resin parts are obtained that will bend, stretch and support long operating cycles without tearing.

    The Elastic Resin is the softest of the resins that Formlabs has available, mechanically complemented with a high percentage of elongation (160%) and a tear strength of 19.1 kN/m. These properties, together with the translucent finish, make this resin a suitable material for prototypes of fashion accessories and consumer goods, models and medical devices, compatible parts with robotic and special accessories.

    High Temp Resin

    High Temp Resin (High temperature resistance) has the highest resistance to bending under temperature (HDT) of all resins, 289ºC to 0.45MPa.

    High Temp Resin HDT and Tesnile Modulus

    With its low thermal expansion and high tensile modulus, it can be used to print models for environmental tests, molds and masters for casting and thermoforming, in a much faster, cheaper and even more accurate way than with conventional methods.

    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.
