Additive manufacturing technologies
Published in Adedeji B. Badiru, Vhance V. Valencia, David Liu, Additive Manufacturing Handbook, 2017
The use of the STL format limits the exchange of trades data (§2.2). If the STL format allows exporting from a surfacing model toward the specific software, the designer needs to insert rules in upstream work in CAD. The emergence of more enriched new exchange format appears such as the additive manufacturing file format (AMF) with important parameters (<material>, <composite>, <metadata>, etc.) or the STL 2.0 (Hiller and Lipson 2009). Alternative file format exports are also required to support depiction of complex organic geometry, while allowing multiple-material and mono/multicolor capabilities; the development of STL 2.0 or AMF is promising, particularly for the composition of complex geometries and multiple materials (Paterson et al. 2012). The article shows that we need to transfer more trades data to the AM machine through an enriched exchange format. The standard ISO/ASTM 52915:2013 Standard specification for additive manufacturing file format (AMF) Version 1.1 (International Organization for Standardization: www.iso.org) describes a framework for an interchange format to address the current and future needs of AM technology.

A newer CAD output format for 3D printing is the open standard (ISO/ASTM 52915-16, 2013), XML based, AMF file (from “Additive Manufacturing File Format” and has an “.AMF” extension). Unlike STL, vertices, edges, materials, and colors are natively defined in the AMF file format, allowing for vector graphic like scaling and simplified translation of multiple materials (or colors) to multinozzle 3D printers.

There are a number of formats available for 3D model representation in AM, such as the STL format, 3D manufacturing format, additive manufacturing file format, and Wavefront object format (Qin et al. 2019b). Among these formats, STL is the most used format and has been the actual standard 3D model format in AM. Almost all CAD (computer-aided design) systems can read and write STL files, and almost all AM machines include the support of the STL format. Without loss of generality, the proposed method takes the 3D models encoded by the STL format as input.
A short survey of sustainable material extrusion additive manufacturing
Published in Australian Journal of Mechanical Engineering, 2023
Step 1: A computerised virtual 3D model is designed and then converted into a standard AM file format. The acceptable formats in 3D printers are standard tessellation language (STL), additive manufacturing file format (AMF) and 3D manufacturing format (3MF). Among these formats, STL is the most commonly used one (Kumar and Dutta 1997).
