Introduction: 3d Print Clay in 2 Colors
how to print mixed porcelain in 2 colors
Step 1: Choose the Materials
to mix the clay, we have to choose the same kind of porcelain (high or low firing temperature) to avoid fails during the firing.
Step 2: Mixing
I use a Wasp clay kit to print in clay with a delta printer.
to prepare the clay, I usually mix the porcelain with 5% distilled alcohol. alcohol is better then water in this case because it evaporates quickly and allow to make the base of the 3d printed part solid in few minutes and prevent the collapse.
Step 3: Pressuring the Tank
Wasp clay kit, work with a pressure and mechanical system.
the tank have inside the clay and a piston and work with 4 to 6 bars of pressure.
the pressure create a kind of vortex in the tank and in the exit tube the 2 kinds of porcelain are mixed casually
