Biomed Resin - FormLabs

In order to ensure a successful 3D printing process and a correct result, the following usage tips must be followed with FormLabs resins:

Cartridge change

In order to replace the resin cartridge, the top cap of the vent should be closed, and the cartridge should be removed using the handle. Then the new cartridge is inserted and the vent should be opened if a 3D printing process is planned. To avoid staining the 3D printer with resin, this process should always be carried out with the resin tank mounted.

Once the 3D printing process is terminated, the top cap must be closed in order to preserve the properties of the resin. If the printer is not used for some time, the cartridge should be stored in its original box to keep the properties of the resin from degrading.

Resin tank and printer compatibility

The BioMed White and BioMed Black resins are compatible with the Form 2, Form 3B/3B+ and Form 3BL printers.

Each resin should be used with the appropriate resin tank. Each tank should be changed after using 2L of resin. The resin tanks compatible with the BiomMed White and BioMed Black resins are the Form 2 Standard resin tank, the Form 2 LT resin tank, and the Form 3 resin tanks.

To protect and properly store the resin after each printing, a lid should be placed on the tank to ensure a perfect closure. Then, the tank should be stored in the original box to avoid exposure to UV light. The tank should not be cleaned with isopropyl alcohol, otherwise the tank will lose its qualities and cause continuous failed impressions.

Resin contamination

There may be leftovers from the previous 3D printing process left in the resin tank. This is why it is recommended to remove leftovers from the tank by using a spatula at an angle of 45 º.

To further ensure that the resin has no contaminants, the resin can be sifted through a piece of paper of 190 µm and then poured back into the tank.

Isopropyl alcohol

Isopropyl alcohol (IPA), used in the washing and post-processing of 3D printed parts, should be changed regularly. In case of using the FormLabs Finish Kit, the IPA should be changed when it is so saturated with resin particles, that 3D printed pieces are still sticky after washing. When that happens, all the liquid should be removed, the container should be cleaned and new IPA should be added. New IPA should never be added to old IPA.
