Page 2: Installation
Biostar ® The computerized Biostar pressure molding machine features modern micro processing electronics designed to improve the ease of operation and thermal forming results. Installation Before removing the machine and its components from the shipping box, determine the location for the Biostar in the laboratory. The machine’s size and weight are outlined on page 3. - Page 3 After inspecting the items, remove all packing material, and position the Biostar unit on the laboratory bench. To prevent machine malfunctions as a result of excessive dust, do not place the unit near etcher catchers, micro etchers, or any area where extensive plasterwork will occur.
- Page 4 CODE: Three-digit code to identify heating and pressure molding times. (t): Heating Time: Time that material is to be heated. TEMP: Actual Temperature: Actual temperature of the heating lamp. (Ts) and (T) should be equal prior to operation. (P): Pressure: Operating air pressure. Appears on screen every 10 seconds.
- Page 5 1. Plug one side of the electrical cord in the back of the Biostar and the opposite end into a three prong 110v outlet. 2. Connect the Biostar to the air source using the high-pressure hose. Secure it in place with a hose clamp.

Page 6: Maintenance
Reminder: Do not use material thicker than 5.0mm within the clamping mechanism. This may cause the Biostar to malfunction while pressure is in the chamber. Always wear safety glasses when using this machine and during all fabrication procedures. Maintenance A regular maintenance schedule should be followed. Proper maintenance will assure better fabrication results. - Page 7 Air escape holes are present in the base of the pellet cup and should be checked monthly to ensure that they remain open. Use a .036” or thinner diameter wire to open plugged holes. Also, make sure the rim of the pellet cup and the four blocks that support the cup are clean.

Page 8: Operation
Operation There are three basic functions to operate the Biostar including: • Model preparation • Heating cycle • Pressure molding process Preparation of Models 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. - Page 9 Remove model bubbles and detail the oral anatomy with a laboratory knife. Fill holes in the model with a quick setting stone. When referencing the model to the platform, make sure the base of the model is reduced flat, parallel to the occlusal surface. In some cases, the base is removed creating a flat horseshoe model to eliminate excessive material stretching.
- Page 10 Enough pellets must be placed in pellet cup to hold the model at proper level. Material termination areas, located on the facial surface of the model, should be referenced at the same height as the top ledge of the pellet cup. Models attached to articulator mountings may be referenced slightly higher than indicated.
- Page 11 For example, when constructing an orthodontic retainer, the pellets are placed against the occlusal-incisal margin to cover the wax holding the wires facially. The pellets act as an insulator when the heated material is formed. Improper packing of a model (shown at left) can cause a blowout, air leak or machine malfunction.

- Page 13 Note: To ensure a tight seal between the pressure chamber and the cup, pellets should be completely removed from around the rim. To initiate heating, swing the heating element over the clamped material and the programmed time will start to count down automatically. With five seconds remaining in the heating phase, a series of short beeps will sound, at zero, a sustained beep will sound.
- Page 14 Great Lakes recommends: all soft or semi-soft material should be formed on the platform. See photo on left: the base of the model is even and flat. Use pellets for hard Great Lakes recommends: all soft or semi-soft material should be formed on the material (see photo on right).
- Page 15 BIOSTAR Maintenance Tips ® A regular maintenance schedule should be followed. Proper maintenance will assure better fabrication results. Refrain from using water in the Biostar® machine. Water may cause certain components to rust or corrode. When the machine is not being used, engage the clamping frame to the chamber and position the chamber on the pellet cup.
