Isopropyl Alcohol (IPA) is the ideal liquid to clean the remains of liquid resin deposited on the surface of a piece made in a resin 3D printer (SLA, LCD, DLP). After each impression made with resin 3D printers (SLA, LCD, DLP) the pieces have a surface layer that doesn’t It has completely solidified, that’s why a bath in isopropyl alcohol is necessary. The interaction of the alcohol with the resin in liquid state releases it from the solid part without creating any deformation or damage in the pieces made.
When cleaning polycarbonate or acrylic surfaces, such as the cover of resin 3D printers (SLA, LCD, DLP), this alcohol or other cleaning products based on ammonia shouldn’t be used as it’s very likely that they cause damage. The IPA alcohol can also be used to clean resin spills, but first it’s recommended to ensure that it doesn’t damage the area to be cleaned. For that, a small test must be carried out in a corner to check whether or not it affects the surface to be cleaned.
Isopropyl alcohol is a colorless, flammable alcohol with an intense odor and very miscible with water. As it’s a flammable element with an intense smell, it should be stored in a ventilated area, dry and away from sources of heat, sparks or flames.
