![]() ![]() So every time the printer moves to a new location or feeds more filament this is a line of code. The slicer program you use takes care of the translation between the output of your cad and the gcode necessary to drive the printer. The same concept has been adopted by non-cutting machines such as photoplotters and 3d printers.ĭifferent codes are used for different functions, the file is in text so can be looked at with notepad. The CNC gcode tells the machine to move a tool to a certain position and start cutting. It tells the computer aided machines how to do something. It has been used for donkey’s years in the electronics industry and later in the CNC mechanical machines. This file format is also known as RS-274. The file format has been designed to be forwards and backwards compatible. The tags – like in html, are specific to each application. The xml author must define both the tags and the document structure. ![]() It is only when a program is written to take the information and display it in a form the user understands that it becomes useful. Xml is a widely used format, which in itself does not do anything. ![]() It can be opened by the widest range of programs The file contains 3d co-ordinates, texture maps polygonal faces along with other information. obj format is widely considered to be the universal format for 3d image editing applications. ![]() The COLLADA format is now supported jointly by sony and the Kronos group. dae file format with a view to exchanging digital assets between multiple graphics programs.īased on the COLLADA ( COLLAborative Design Activity) xml schema, now owned and developed by Autodesk. This file type can be opened with : Windows Colours are described using the RGBA ( red, green, blue and alpha channels) values. It uses triangular meshes to describe surfaces. It is XML based and is designed to be simple, scalable, forwards and backwards compatible. The American Society for Testing and Materials (ASTM) released an open format. This file type can be opened with: WindowsĪs time goes on and 3d printers become more complex the need for a new standard was identified. The colour mixing of the Zmorph printer already uses their own software rather than the usual slicer. stl (stereolithography) format will not allow the addition of colour – so two colour printer will struggle to use the file format without major modifications. This is still the most popular, but I can see this fading away into the distance with new printers coming onto the market.
