It is generally not necessary to wash 3D resin prints. However, there may be times when it is beneficial to do so. For example, if your print is painted or otherwise altered, washing it first can help ensure that the paint adheres properly. Additionally, if your print is going to be stored for an extended period, it can help remove debris that could cause it to degrade. In general, however, simply wiping down your print with a lint-free cloth should be sufficient to keep it clean.
