FormLabs Engineering Resins are a set of resins developed to solve the most complex engineering challenges thanks to the wide variety of functional materials. In addition, these materials help to reduce costs and make quality prototypes and final parts very quickly. Within this family of resins are the Rigid resins.

Formlabs' Rigid resins are strong and stable resins, ideal for creating strong and rigid prototypes of parts that are resistant to bending. This family includes:

Rigid Resin 4000 (formerly called Rigid Resin)
Rigid Resin 10K

Parts made from these materials are thermally and chemically resistant and their dimensions remain stable under load.

These resins are ideal for: Turbines and fan blades, guides, fasteners and tooling, fluid and air flow components, covers for electrical appliances or covers for appliances in cars among others.

When comparing the two resins in the Rigid family, Rigid 4000 resin is more suitable for rigid and resistant engineering parts capable of withstanding minimal deflection, while the high glass content of Rigid 10K resin makes it ideal for the manufacture of extremely rigid and resistant industrial parts that require complete rigidity and high stability.

Rigid Resin 4000

The Rigid Resin 4000 is a resin highly reinforced with glass, giving it a high rigidity and a completely smooth or polished finish. It's also resistant to temporary deformation and allows to print thin-walled parts, but at the same time resistant.

Rigid 4000 resin is comparable to other fiberglass reinforced thermoplastics. Compared to parts printed with other Formlabs materials, parts printed with Rigid 4000 resin resist mechanical stress for a longer period of time.

Rigid 10K

As for Rigid 10K resin, it is the most rigid material in Formlabs' range of engineering resins, making it ideal for industrial parts that need to support a significant load without bending. Rigid 10K resin has a smooth matt finish and is highly resistant to heat and chemicals.

Because of its properties, 10K Rigid resin can be used for high performance applications in a variety of industries such as automotive and aerospace.

One of the newest applications of 10K Rigid resin is injection moulding. By incorporating 3D printing into the injection molding process, manufacturers can eliminate time-consuming and costly metal machining. The toughness, rigidity and heat resistance of 10K Rigid resin make it an ideal material for short series injection moulding.

Due to the properties of the material, a mould made from this material can withstand the pressures of injection without breaking. Its stiffness ensures that the mould maintains its shape even under pressure, resulting in precise parts. Its high thermal resistance makes it possible for the mould to maintain its rigidity even at the high temperatures to which the material is exposed during the injection process.

Rigid resins support printing resolutions of 100 and 50 microns, which results in a very high surface finish and level of detail on the pieces.

Thus, the resins of the Rigid family are very useful materials in a wide variety of sectors and applications thanks to their mechanical properties.

Thanks to Rigid Resin family and other FormLabs engineering resins, costs can be reduced and quality prototypes and final parts can be made very quickly.

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.

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.
