HRZ to STL Conversion: FAQ

What are HRZ files?

HRZ is an image format associated with slow-scan television (SSTV) software. This obsolete mode of video communication implies a slow transmission of still images and is generally fitted for limited bandwidth conditions, requiring specialized software. Opening HRZ images with regular image viewers is not very likely, so for easier access we recommend converting to a more popular format, such as JPG or PNG.

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. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
