ABC to STL Conversion: FAQ

What are ABC files?

ABC (Advanced Bitonal Compression) is a proprietary image format designed by Lead Technologies for storing scanned documents of all types and sizes. The format is included in a larger imaging pack called LeadTools and its main advantage is the use of a 1-bit compression algorithm, allowing great image quality at a smaller file size when compared to other similar formats available. This translates into easier access, storage and transmission, which adds to the option of using lossless or lossy compression.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing.
