Check our videoThe STL file format is a widely used standard for representing 3D models, primarily in 3D printing and computer-aided design (CAD). It is supported by most CAD software, 3D modeling tools, and slicing programs like Cura, PrusaSlicer, and Simplify3D. The format stores surface geometry as a collection of triangular facets, defined by vertices and normals, but lacks advanced features like color, texture, or metadata, making it simple yet limited for complex applications.
The BMP format is a raster graphics image file format used to store bitmap digital images, primarily on Windows systems, and is known for its simplicity and lack of compression. It is widely supported by image editing software like Adobe Photoshop, GIMP, and Microsoft Paint, as well as various operating systems and tools for basic image manipulation. The format stores pixel data in a straightforward manner, with optional support for color depths, alpha channels, and basic compression methods like Run-Length Encoding (RLE), though it is generally uncompressed, leading to larger file sizes compared to other formats.
You can also convert STL into many other file formats. Please see the complete list below.
