Computer numerical control (CNC) is a type of machining that uses data and programs to perform cutting, drilling and milling operations. CNC technology has been very important in the manufacturing industry since its introduction. In the past, machinists had to manually program machines to complete a task. This is time-consuming and prone to human error.

3D printing is a process that allows manufacturers to create various types of objects with the most diverse materials. This allows them to determine the exact shape and characteristics of their finished product. Compared to traditional prototyping methods, 3D printing can be done with minimal steps. Before a 3D printed product can be made, an STL image of the design is first sent to the manufacturer. This allows a computer to view the design from various angles and perspectives. But which material is best to use for our prototypes?

The MCP23017 is a 16-bit port expander with 32 channels of 12-bit analog-to-digital converters and two generic 8-bit inputs / outputs. Unlike most other port expanders, the MCP23017 has an internal oscillator. The MCP23017 operates at 2 MHz, but can support frequencies up to 1 MHz; It can be cascaded and comes in an 18-pin PDIP package, so you can use it in breadboards and through-hole soldering perfboards. This makes it easy to connect it to other parts of the circuit.

The extruder is the part of a 3D printer responsible for pushing and liquefying the filament to form each layer. Some printers have one, others two or three! The extruder can be built in aluminum, steel or other metal alloys, depending on the needs. It is typically part of the hot end assembly, which also includes a nozzle orifice. The extruder works by pulling the filament through a heated nozzle at a specific speed, so that it melts and then pushes a thin layer of material onto the platform.
