Attached is an excellent report that provides a powerful global overview of 3D printing and 3D scanning, plus a wide range of current and emerging standards.

	Technology Trend Report on 3D Printing and Scanning
	September 30, 2016
	ISO/IEC JTC 1 Plenary (November 2016, Lillehammer, Norway)
	Prepared by the ISO/IEC JTC 1 Advisory Group (JAG) 3D Printing and Scanning group

Executive summary
The purpose of this report is to assess the possible contributions of JTC 1 to the global market enabled by 3D Printing and Scanning.

3D printing, also known as additive manufacturing, is considered by many sources as a truly disruptive technology. 3D printers range presently from small table units to room size and can handle simple plastics, metals, biomaterials, concrete or a mix of materials. They can be used in making simple toys, airplane engine components, custom pills, large buildings components or human organs. Depending on process, materials and precision, 3D printer costs range from hundreds to millions of dollars.

3D printing makes possible the manufacturing of devices and components that cannot be constructed cost-effectively with other manufacturing techniques (injection molding, computerized milling, etc.). It also makes possible the fabrications of customized devices, or individual (instead of identical mass-manufactured) units.
3D printing is expected to have a large impact on the economics of global manufacturing. 3D printing, coupled with 3D scanning, also raises significant issues related to international copyright laws.

The data that drives a 3D printer can be generated either by a CAD system or a 3D scanner, or both. This data is machine interpretable and can use an open or proprietary formalism. The formalism might be open-source or proprietary. It needs to be stored, exchanged, indexed, secured, etc. The integrity of the data, especially for safety or mission critical components or devices, must also be ensured.

Together these developments show that many standards and projects for JTC 1 entities are relevant to 3D Printing and Scanning.

This report was produced to support further discussions on this topic by the JTC 1 Advisory Group. Given the potential impact of this IT intensive technology on global commerce, JTC 1 should create and mandate a Study Group to further assess its potential contribution in the area of 3D Printing and Scanning.

JTC 1 is the senior International Standards Organization (ISO) body focused on Information Technology.  They already supervise many of the central standards efforts, and have a strong influence on the other relevant standards development organizations (SDOs).
| JTC 1 is the standards development environment where experts come together to develop worldwide
|Information and Communication Technology (ICT) standards for business and consumer applications.
| Additionally, JTC 1 provides the standards approval environment for integrating diverse and complex ICT technologies.
| These standards rely upon the core infrastructure technologies developed by JTC 1 centers of expertise
|complemented by specifications developed in other organizations.

Of note: the work of Web3D Consortium and Extensible 3D (X3D) Graphics International Standard indeed appear to be central in the broader set of capabilities that seem to be emerging.  Of particular interest is Annex 3, which provides a 3-page overview summary of all efforts relating to X3D Graphics for CAD, 3D Printing and 3D Scanning.

An important insight for X3D during the past year is that CAD model export, 3D printing and 3D scanning are closely interrelated and might all be handled in a single X3D profile.  The attached report documents many useful capabilities and candidate requirements for this continuing endeavor.

Thanks to Anita Havele, Vince Marchetti, Christophe Mouton, Nicholas Polys, Roy Walmsley and all other Web3D Consortium participants for their review and contributions.

Follow-on work: the CAD Working Group is building on progress from this past summer's workshop at the Web3D 2016 conference.  We are next working to document this strategy with examples, work flows and tools that will soon be elaborated in a detailed technical report.


Exciting opportunities are beckoning!  Report feedback, observations, and further participation in the CAD Working Group are welcome.

all the best, Don
