3D printers

3D  printers  A 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process of an object that is being created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. Slicing: From printable file to 3D Printer Slicing basically means slicing up a 3D model into hundreds or thousands of layers and that is done with slicing software. When your file is sliced, it’s ready for your 3D printer. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Your sliced fi...

Data types in C language

Data Type Datatype is an entity that defines a set of values and a set of operations that can be applied on those values. It determines the type and size of data associated with variables. Data type in C language Primary data types Primary data types are also known as the fundamental data types because they are pre-defined or they already exist in the C language. All C compilers support four fundamental data types, namely int, char, float, and void. Derived data types Derived data types are derived from the primitive or fundamental data types. There are mainly 3 types of derived data types in C There are mainly 3 types of derived data types in C Array Function Pointer User defined data types The data types that are defined by the user are called the user-defined derived data type. For this a special keyword is needed such as typedef, enum, struct, union. The C program consists of the following types of UDT: Structures Union Typedef Enum
