Abstract
The National Institute of Standards and Technology (NIST), an agency of the United States Department of Commerce, in support of efforts to establish the measurement science required for development of the standards and industry for Additive Construction by Extrusion (ACE), is establishing the Additive Construction by Extrusion (ACE) Consortium ("Consortium"). The Consortium will bring together stakeholders to identify and address gaps in current standards related to materials, methods, structural performance, and engineering design. The Consortium efforts are intended to study the measurement science needs for the successful adoption of ACE by the construction industry, and to identify and propose new standards to address industry needs not met by existing standards. Participation fees will be at least $10,000 annually or in-kind contributions of equivalent value. Participants will be required to sign a Cooperative Research and Development Agreement (CRADA). At NIST's discretion, entities which are not permitted to enter into CRADAs pursuant to law or other governmental constraint may be allowed to participate in the Consortium pursuant to a separate non-CRADA agreement.

DEPARTMENT OF COMMERCE
National Institute of Standards and Technology
Additive Construction by Extrusion (ACE) Consortium
AGENCY: National Institute of Standards and Technology, Department of
Commerce.
ACTION: Notice of research consortium.
-----------------------------------------------------------------------
SUMMARY: The National Institute of Standards and Technology (NIST), an
agency of the United States Department of Commerce, in support of
efforts to establish the measurement science required for development
of the standards and industry for Additive Construction by Extrusion
(ACE), is establishing the Additive Construction by Extrusion (ACE)
Consortium (``Consortium''). The Consortium will bring together
stakeholders to identify and address gaps in current standards related
to materials, methods, structural performance, and engineering design.
The Consortium efforts are intended to study the measurement science
needs for the successful adoption of ACE by the construction industry,
and to identify and propose new standards to address industry needs not
met by existing standards. Participation fees will be at least $10,000
annually or in-kind contributions of equivalent value. Participants
will be required to sign a Cooperative Research and Development
Agreement (CRADA). At NIST's discretion, entities which are not
permitted to enter into CRADAs pursuant to law or other governmental
constraint may be allowed to participate in the Consortium pursuant to
a separate non-CRADA agreement.
DATES: The Consortium's activities will commence on October 15, 2023
(``Commencement Date''). NIST will accept letters of interest to
participate in this Consortium on an ongoing basis.
ADDRESSES: Completed letters of interest or requests for additional
information about the Consortium can be directed via mail to the
Consortium Manager, Dr. Shawn Platt, Materials and Structural Systems
Division of NIST's Engineering Laboratory, 100 Bureau Drive, Mail Stop
8615, Gaithersburg, Maryland 20899, or via electronic mail to

SUPPLEMENTARY INFORMATION: Additive construction by extrusion (ACE)
technology has the potential to revolutionize the construction industry
by eliminating the need for formwork and enabling architectural and
structural designs that cannot be achieved through current standard
practices. As ACE remains in the early stages of development, this
Consortium will study the measurement science needs for the successful
adoption of ACE by the construction industry. The objective of this
Consortium is to identify and then translate cementitious material
measurements to in-line or in-process measurements for quality control
and quality assurance in the ACE process. Participants in the
Consortium will work with NIST toward the following goals:
(1) Correlating Off-Line Measurements to Print Quality
A focus will be on correlating off-line measurements of fresh and
hardening ink to a measure of print quality. The objectives are to
determine material performance characteristics that are critical to the
success of ACE.
(2) In-Situ and In-Process Measurements
A focus will be on developing in-situ and in-process measurements
that may be used to provide feedback into the control of the ACE
process. The objective is to implement material property measurements
in line to the ACE process.
(3) Hardened Properties and Scaling up From Paste to Concrete
A focus will be on measurements at the structural scale, including
a proper consideration of in-field issues. This includes, but is not
limited to, hardened property measurements; studies on curing practices
and finishing procedures; and development of numerical simulations of
material deposition. The objectives are to develop measurement
techniques to assess hardened properties of 3-D printed structures and
investigate how early age properties and measurements may inform ACE
through the use of numerical simulations.
Participation Process
NIST is soliciting responses from all sources, including other
Federal Government agencies, State or local governments, foreign
government agencies, industrial organizations (including corporations,
partnerships, and limited partnerships, and industrial development
organizations), public and private foundations, and nonprofit
organizations (including universities). Eligibility will be determined
by NIST based on the information provided by prospective participants
in response to this notice. NIST will evaluate the submitted responses
from prospective participants to determine eligibility to participate
in this Consortium. Prospective participants should provide letters of
interest with the following information to NIST's Consortium Manager:
1. Narrative of interest in ACE and description of related
experience and expertise to contribute to the Consortium.
2. List of anticipated participating individuals.
3. If proposing in-kind participation instead of a fee
contribution, description of anticipated in-kind donation and its
equivalent value to fee.
Letters of interest must not include business proprietary
information. NIST will not treat any information provided in response
to this notice as proprietary information. NIST will notify each
organization of its eligibility. In order to participate in this
Consortium, each eligible organization must sign a CRADA for this
Consortium. Entities which are not permitted to enter into CRADAs
pursuant to law or other governmental constraint may be allowed to
participate in the Consortium, at NIST's discretion, pursuant to
separate non-CRADA agreements with terms that may differ, as necessary,
from the Consortium CRADA terms.
Participants will contribute US $10,000 annually in funds or
equivalent in-kind contributions to be members of the Consortium. NIST
does not guarantee participation in the Consortium to any organization
submitting a letter of interest. This phase of the Consortium will be
for up to five years.
Authority: 15 U.S.C. 3710a.

NIST Executive Secretariat.
