What is IPP? The Internet Printing Protocol (IPP) is a secure, highlevel printing protocol originally developed 20 years ago that is supported by almost all 2 D printers sold today. • Used over traditional wired and wireless networks, Wi. Fi Direct, and USB. • Core protocol for Air. Print™, IPP Everywhere™, Mopria®, and Wi-Fi Direct Print Services. • Semantics and data model were also used as the basis for Bluetooth BPP and Windows XPS printing. Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO. ®

IPP Features • IPP provides a descriptive, extensible high-level protocol for expressing: • Printer information (identification, location, etc. ) • Printer capabilities • User intent via a Job Ticket (number of copies, finishings options, etc. ) • Printer and Job status information (supply low/empty, jams, job waiting for input, etc. ) • Direct and indirect (cloud) printing. • Encrypted (TLS/HTTPS) communications, authentication, and access control.

What is IPP 3 D? • IPP 3 D is a version of IPP for 3 D printers • Extends and adapts the model used for 2 D printers to 3 D printers: • 3 D printing materials, temperature/humidity, accuracy requirements/print quality, etc. • Capability information needed for print file generation • Support for cameras • Provides guidance/recommendations for existing 3 D printing file formats (3 D PDF, 3 MF, G-Code) Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO. ®

IPP 3 D Use Cases • Print a 3 D object has loaded • Print a 3 D object • View a 3 D object using whatever materials the printer using specific materials using an intermediate (cloud) service using a service bureau as it is being printed Copyright © 2018 The Printer Working Group.

® The Printer Working Group What's New in 2018 Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO.

What's New in 2018 • IPP Get-User-Printer-Attributes • New operation to enable per-user IPP capabilities (print policy) • IPP Presets • IPP attribute that bundles together a set of Job Template Attributes with a localizable label and an optional attribute trigger to apply the settings in a batch • IPP Privacy Attributes • Defines attributes for specifying the privacy policies of Document, Job, Printer, and Subscription objects. Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO. ®

2018 3 D Work In Progress • IPP 3 D Printing Extensions v 1. 1 • Making 3 MF CONDITIONALLY REQUIRED for Printers that do Slicing, RECOMMEND support for a standard layered format otherwise • Adding new attributes • "material-nozzle-diameter" and "material-retraction" member attributes added to "materials-col" • "platform-shape" Printer Description attribute • "chamber-humidity" and "chamber-temperature" Job Template attributes • Defining a naming convention for standard "materialtype" values for extensibility similar to MSN 2 (PWG 5101. 1) to allow for specification of standard (ASME/ISO/etc. ) materials • Schedule: Approve/Publish in late 2018/early 2019 Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO. ®

2018 3 D Work In Progress (con't) • PWG Safe G-Code Subset for 3 D Printing • Best practice document that defines a "safe" subset of G-code for use in 3 D printing with IPP along with the capabilities and parameters needed to allow a Client (or cloud service) to generate generic G-code compatible with any Printer • Specifically to enable existing G-code based printers to adopt IPP 3 D and existing cloud services to support IPP 3 D printers • Not standards track since G-code only supports a subset of 3 D printers and has many well-known issues • Schedule: Publish before the end of 2018 Copyright © 2018 The Printer Working Group. All rights reserved. The IPP Everywhere and PWG logos are registered trademarks of the IEEE-ISTO. ®

2018 3 D Work In Progress (con't) • IPP System Service v 1. 0 • Service for interfacing with the IPP System object • Container that hosts instances of IPP service objects such as the 3 D Print service • Operations create, manage and delete these objects • Get-Printers operation lists all available Printers • With authentication, list will contain only those Printers available for that particular user • Schedule: Complete in 2018 and Approve/Publish in 2019 Copyright © 2018 The Printer Working Group.

America Makes & ANSI Additive Manufacturing Standardization Collaborative (AMSC) • America Makes – Quoted From their web site: • “Established in 2012 and based in Youngstown, Ohio, America Makes is the flagship Institute for Manufacturing USA, the National Network for Manufacturing Innovation, infrastructure of up to 45 Institutes to follow and is driven by the National Center for Defense Manufacturing and Machining (NCDMM). ” • America Makes is a membership driven public – private partnership. While it collaborates with SDO’s (Standards Developing Organizations), it does not develop standards itself. Much of the information created as part of different America Makes sponsored projects is only made available to paying members. • America Makes & ANSI Additive Manufacturing Standardization Collaborative (AMSC) – https: //www. ansi. org/standards_activities/standards_boards_panel s/amsc/Default? menuid=3. The IEEE-ISTO Printer Working Group is participating in the AMSC initiative. • The AMSC Version 2. 0 Work Effort is scheduled to conclude in June 2018 with the publication of the updated 2. 0 AMSC roadmap Copyright © 2018 The Printer Working Group.

RAPID + TCT Conference April 23 rd-26 th, 2018 in Ft. Worth, TX • SME profiled the work of AMSC via a Forum on Tuesday April 24 th, 2018 from 2: 15 to 4: 15 pm • PWG was represented by Paul Tykodi at RAPID on April 24 th, 2018 • Mr. Tykodi was invited to present on the topic “IEEE-ISTO PWG IPP Working Group: Process-Declaring Workflow Intent and Querying Device Capabilities” • SME unveiled their new ITEAM Concept at the RAPID + TCT Conference. Introductory meeting held Mon April 23 rd, 2018 • “The group agreed on the need and that SME is uniquely positioned to serve as the unbiased, trusted 3 rd party in the AM community. To further that effort, SME will stand up the Additive Manufacturing Consortium for the Independent Technical Evaluation of Additive Manufacturing (ITEAM). This consortium will include industry thought leaders from various industries. ITEAM, with the support of the Florida Institute of Technology (FIT), will create a platform to enable inquiry and analysis, education, community forums, and training. This provides an unbiased assessment of AM technology, materials, processes and equipment for AM users and adopters. ” Copyright © 2018 The Printer Working Group. All rights reserved.
