The IEEE-ISTO Printer Working Group (PWG) has released IPP 3D Printing Extensions v1.1 (PWG 5100.21-2019) and PWG Safe G-Code Subset for 3D Printing v1.0 Best Practices (PWG 5199.7-2019). These documents build on previously defined extensions to the Internet Printing Protocol (IPP) Internet Standard (IETF STD92) that combine existing high-level 3D file formats with the IPP network printing protocol and Job Ticket formats to describe the printer’s capabilities, the objects to print, and the status of submitted jobs to better and more portably produce physical objects with additive manufacturing devices, also known as 3D printers.
