Operation

There are three basic functions to operate the MiniSTAR S including:

Model preparation

•

Heating cycle

Pressure molding process

•

Model Preparation

Prepare models for the thermal-forming process by removing bubbles or filling voids whether using the platform or

pellets. The platform is used when forming soft or thin plastics. Pellets are used when forming thick, less flexible

materials. The pellets prevent the plastic from forming to unwanted areas of the dental cast, reducing material thinning.

Platform Use

The platform is used to expose the entire dental mold to the formation of the thermal plastic. It eliminates having to

use pellets. Pellets are difficult to remove from softer material (i.e., soft mouthguard material) and can create a higher

occurrence of air leaks during the pressure-forming process when using thinner thermal plastics (i.e., < 1mm thick).

Check the air filter clamped to air line (white arrow) monthly

for discoloration and/or moisture.

If replacing the filter, turn off the air source and bleed the

high-pressure hose of air. Loosen clamps holding the filter

and slide it off the hose. Position the new filter by referencing

the arrow on the filter case toward the back of the MiniSTAR S.

The heating surface (A) should be parallel to the heating

element (B). Adjust the position of the chamber by turning

the screw (C) located under the chamber support frame with

a small screwdriver.

Clockwise adjustment of the screw lowers the chamber from

the heater, counterclockwise raises the chamber closer to the

heater.

Check the position of the chamber when heating materials.
