PDF to STL Conversion: FAQ

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics. As opposed to other formats with a similar function, PDFs can be easily transferred between different applications and different operating systems, and generally don't have a very large size. Moreover, they can offer decent image quality in a compressed format and can be secured with passwords or watermarks.

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.
