G-code (abbreviation for geometric code; also called RS-274 [citation needed]) is the most widely used computer numerical control (CNC) and 3D printing programming language. It is used mainly in computer-aided manufacturing to control automated machine tools , as well as for 3D-printer slicer applications .
A slicer is a toolpath generation software used in 3D printing. It facilitates the conversion of a 3D object model to specific instructions for the printer. The slicer converts a model in STL (stereolithography) format into printer commands in G-code format. This is particularly usable in fused filament fabrication and other related 3D printing ...
Ultimaker Cura works by slicing the user’s model file into layers and generating a printer-specific g-code. Once finished, the g-code can be sent to the printer for the manufacture of the physical object. [8] The open source software, compatible with most desktop 3D printers, can work with files in the most common 3D formats such as STL, OBJ ...
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
In 3D printing, G-code translates a 3D model, created in a specialized 3D printing format, into specific instructions that guide the printer. This includes commands for movement along the X, Y and Z axes , extrusion of material, temperature settings, and printing speed. [ 3 ]
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Both are complete systems for translating 3D computer models into G-code, the machine language that commands the printer. Later, other programs like Slic3r and Cura were created. Recently, the Franklin firmware was created to allow RepRap printers to be used for other purposes such as milling and fluid handling. [16]
Additive manufacturing file format (AMF) is an open standard for describing objects for additive manufacturing processes such as 3D printing.The official ISO/ASTM 52915:2016 [1] [2] standard is an XML-based format designed to allow any computer-aided design software to describe the shape and composition of any 3D object to be fabricated on any 3D printer via a computer-aided manufacturing ...
