Stereolithography File (.stl)

STL, short for Stereolithography, is a widely used file format in the realm of 3D printing and computer-aided design (CAD). Introduced by 3D Systems in 1987, it represents the surfaces of a 3D object through a collection of triangles, facilitating precise and efficient model creation. Utilized across various industries such as engineering, manufacturing, and healthcare, STL files are critical for prototyping and producing complex geometries. Their simplicity and compatibility with numerous software applications have cemented STL's importance in the digital fabrication landscape.

3D Manufacturing Format (.3mf)

The 3D Manufacturing Format (3MF) is a file extension used in additive manufacturing, commonly referred to as 3D printing. Developed by the 3MF Consortium, it provides a streamlined and improved format over traditional STL files. Introduced in 2015, the 3MF format supports richer data representation, including color, material, and other properties, ensuring better interoperability and more accurate print results. Its adoption has facilitated enhanced efficiency and precision in the 3D printing industry, making it a preferred choice for professionals in the field.
