Stirring device for optimum consistency The LC-3D Mixer is a roller/tilting stirring device for mixing 3D printing materials before pouring in the Resin Tray of the printer. Print resins must be mixed well. Only handshaking is insufficient for highly filled and colored materials. The LC-3D Mixer should be used to thoroughly mix the material. When mixed insuf?ciently color deviation and print failures may occur. The NextDent LC-3D Mixer keeps your NextDent 3D materials ready for use at any time at an optimum consistency. Always follow the instructions for use relevant to the corresponding material.
