Master Pattern Production
Preparation of the master is the key to successful mold making and part casting. Every detail of the
master’s surface finish will translate to the cast pieces. The polished appearance of an injected
molded part is often the goal when prototyping with RTV molding. To achieve the polished
appearance, prepare the surface finish of the master pattern by following the seven steps listed
below. Note that it is only necessary to follow these steps to achieve the appearance of an injected
molded part with an ultra-smooth finish.
Instructions:
1. Remove, post-process and infiltrate the printed part from the Z Corporation 3D Printer. Infiltration
with cyanoacrylate or epoxy is recommended. The use of wax is not recommended because the
part will not accept a primer later in the finishing process and is not easily sanded.
2. Sand the part with 100-grit sand paper after it has been
infiltrated with either epoxy or cyanoacrylate. Sand the
part so there are no pits in the surface.
3. Coat the part with a filler, such as Bondo
®
No. 907 Glazing & Spot Putty, being sure to fill in any
remaining pits. You can also use a fast curing spackling putty. Both putties are applied wet and
dry quickly at ambient temperatures.
