Hydro Dipping Sheets - 10 Pack of A4 Size SheetsHydro dipping is a fun, hands on way of adding printed designs to any surface! This process can be done on any material that can hold the base coat and can be submerged into water. It works especially well with 3D printed projects, molded, and cast parts. When done right, you can cover an entire shape with colorful ink like motorcycle helmets and ceramic statues. Start by using an ink jet printer (laser printers won't work!) to print your design.
