Cos'è un file AMF?

AMF (Additive Manufacturing Format) is an ISO 52900:2015 open standard to address STL limitations for modern additive manufacturing. AMF uses XML for curved triangular elements, per-vertex color, multiple materials with volumetric composition, assemblies and measurement units.

Usi comuni dei file AMF

Multi-Material 3D Printing

AMF can specify different materials for different regions of a print, including material gradients.

Color 3D Printing

Unlike STL, AMF stores per-vertex RGB color for full-color print files.

Precision Mesh Representation

AMF curved triangle elements reduce the need for ultra-fine tessellation for smooth curved surfaces.

Converti questo formato

Commonly converted from STEP or STL for color printing, to 3MF (more widely adopted), or to STL for legacy slicer compatibility.
