Dental LT Clear V2 Resin - FormLabs

Parts 3D printed with the Dental LT Clear V2 Resin require post processing in order to ensure their optimal performance and biocompatibility of the 3D printed dental appliances. Washing should be done in the FormWash automated washing center (20 minutes in IPA). Parts 3D printed with the Dental LT Clear V2 Resin should be first washed for 15 minutes, then soaked in fresh isopropyl alcohol for the remaining 5 minutes. Leaving the parts in the IPA for longer than 20 minutes will result in lower quality of the parts due to excessive solvent exposure. It is also crucial to use separate wash buckets for biocompatible and non-biocompatible materials. As far as curing, it should be done with the help of the FormCure curing chamber (60 minutes at 60 ºC).

After each printing, the excess resin should be properly stored in order to ensure its longevity. Each FormLabs tank comes with a lid and it should be used for perfect closure. Once the tank is closed, it should be stored in the original box so that the resin doesn't lose its properties when exposed to UV rays for a long time. When stored correctly, the Dental LT Clear V2 Resin has a longevity of 24 months.

The tank’s cleaning recommendations should always be consulted before using any cleaning product that may damage the tank (for example, isopropyl alcohol) and result in failed prints. The tank should also be regularly cleaned from solid residues, otherwise a printing error may occur. Any solid pollutants can be removed with a spatula at a 45 º angle, like shown in a video provided by FormLabs.
