Ideal material for direct printing splints, retainers and other orthodontic devices.

FormLabs Dental Resins are specialized materials for the dental field, where the use of this type of technology is increasingly present. The dental resins (biocompatible) allow models of crowns and bridges, surgical guides, splints and retainers to be made with incredible accuracy, with a maximum deviation of ±100 microns, and with very low material costs per element (1.4 - 3.3 ?), which amortizes the use of the printer with any of the dental resins in a few months.

Dental LT Resin offers a high resistance to fracture, wear and biocompatibility Class IIa (EN-ISO 10993-1:2009/AC:2010 EN-ISO, 10993-3:2009, EN-ISO 10993-5:2009, EN-ISO 10993-11, EN-ISO 7405:2009/A1:2013). To ensure the durability and resistance necessary to produce final elements, the Dental Resin LT complies with the mechanical properties stipulated in the EN-ISO 20795-1:2013 standard. This resin is ideal for direct printing of splints, retainers and other orthodontic devices with a translucent finish.

To achieve a finish with an optimal transparency, only a light polish is needed.

To ensure the biocompatibility of Dental LT Translucent resin, the use of dedicated tanks and finishing kits is required which should only be used with this and other Formlabs biocompatible resins.

Much of the dental industry is already using 3D printing, through Form 2 or Form 3B and Dental Resins, to enhance their services more accurately, quickly and economically.

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.
