The F algorithm - Mathematical digression. "The z-value is the change in temperature in degrees Celsius required to alter the D-value by a factor of 10 (the z-value relates the resistance of a micro-organism to changes in temperature)" (EP 10.3, 5.1.5) This definition may be expressed by a mathematical equation: D(T-z) = 10 . Packaged medical devices are loaded into the autoclave, which is then sealed closed. Steam is injected under pressure, displacing the air. It's the moist heat that kills the microorganisms. After sterilization, the steam is dispelled and the packaged medical devices are removed. Heat, moisture, and pressure are the variables to be manipulated material for construction in FDM. Today, there are several derivatives of this material on the market. Five of the nine materials tested in this paper were ABS derivatives: ABSi, ABS-M30, ABS-M30i, ABS-ESD7, and PC-ABS. ABSi's translucent nature allows it to be used when monitoring material flow or transmission of light.
