Part of the Microprocessors glossary: Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC).
STL is the standard file type used by most additive manufacturing systems. STL is a triangulated representation of a 3D CAD model (Figure 1). The triangulation of a surface will cause faceting of the 3D model. The parameters used for outputting a STL will affect how much faceting occurs (Figures 2 and 3).
