One of the key aspects of Circular Economy (CE), particularly when focusing on the product level, lies in its emphasis on designing products to facilitate the circulation of resources and maximize value throughout their entire lifecycle. To effectively

Economics of Digital Twins: Costs, Benefits, and Economic Decision Making

October 30, 2024
Author(s)
Douglas Thomas
This report examines the economics of digital twins in the manufacturing industry, including the costs, benefits, and economic decision to invest in the adoption of a digital twin. It characterizes the costs and benefits along with the circumstances under

Improving Fitting CAD to 3D Point Cloud Acquired with Line-of-Sight Sensor

November 7, 2023
Author(s)
Marek Franaszek, Prem Rachakonda, Kamel S. Saidi
Due to self-occlusions in 3D point clouds acquired with line-of-sight sensors, an incomplete representation of an object's surface is used in fitting a CAD (computer-aided design) model to the data. For certain types of object geometry, CAD pose fitted

In situ Probing of Interfacial Roughness and Transient Phases During Ceramic Cold Sintering Process

October 15, 2023
Author(s)
Fan Zhang, Russell Maier, Igor Levin, Andrew J. Allen, Jun-Sang Park, Peter Kenesei, Ivan Kuzmenko, Jan Ilavsky, Pete Jemian
The ceramic cold sintering process (CSP) offers an eco-friendly approach to producing fully dense ceramics at low temperatures. However, an incomplete mechanistic understanding hinders its optimization and widespread adoption. In this study, we analyze the

RECENT DEVELOPMENTS IN ONTOLOGY STANDARDS AND THEIR APPLICABILITY TO BIOMANUFACTURING

August 21, 2023
Author(s)
Milos Drobnjakovic, Boonserm Kulvatunyou, Vijay Srinivasan, Simon P. Frechette
ISO and IEC have jointly initiated, and recently issued, a series of standards (the ISO/IEC 21838 series) for top-level ontologies. These standards have been used by industrial consortia to develop and disseminate standards for mid-level ontologies to ease

A Methodology for Digital Twins of Product Lifecycle Supported by Digital Thread

February 8, 2023
Author(s)
Laetitia Monnier, Guodong Shao, Sebti Foufou
The technological advancement has led to the transition of manufacturing industries to Smart Manufacturing and Industry 4.0. Promising concepts such as Digital Twin and Digital Thread could help speed up the transition. One of the benefits of using digital

STEP-NC Process Planning for Powder Bed Fusion Additive Manufacturing

October 20, 2022
Author(s)
Fahad Milaat, Paul Witherell, Martin Hardwick, Ho Yeung, Vincenzo Ferrero, Laetitia Monnier, Matthew Brown
Powder bed fusion (PBF) is an additive manufacturing (AM) technology that uses high-power beams to fuse powder material into layers of scanned patterns, thus producing parts with great geometric complexity. For PBF, the selection of appropriate process

Towards the Physical Reliability of 3D-Integrated Systems: Broadband Dielectric Spectroscopic (BDS) Studies of Material Evolution and Reliability in Integrated Systems

September 30, 2022
Author(s)
Papa Amoah, Joseph J. Kopanski, Yaw S. Obeng, Christopher Sunday, Chukwudi Okoro, Lin You, Dmirty Veksler
In this paper, we present an overview of our current research focus in developing non-destructive metrology for monitoring reliability issues in 3D-integrated electronic systems. We introduce a suite of non-destructive metrologies that can serve as early

Simulated stress mitigation strategies in embedded 3D bioprinting

August 30, 2022
Author(s)
Leanne Friedrich, Ross Gunther, Jonathan Seppala
Extrusion-based 3D bioprinting is a powerful tool for fabricating complex cell-laden constructs. Embedded Ink Writing (EIW) is an extrusion-based printing technique wherein a nozzle embedded into a support bath writes continuous filaments. Because it

Advancing Autonomous Robot Development and Adoption Through Standards

May 4, 2022
Author(s)
Craig I. Schlenoff
Autonomy is the ability to perform tasks without help. In the case of autonomous robots, obstacles may arise internally like an electrical short or a broken part or externally such as encountering debris. These instances can cause mission interruption or

Refocusing the Barriers to Sustainability for Small and Medium Manufacturers

February 14, 2022
Author(s)
Xavier R. Escoto, Demsas Gebrehewot, KC Morris
Sustainable manufacturing practices are a necessary component of sustainable development. Current practices in a linear economy—produce, consume, discard—will not be sufficient to sustain humanity over the long term. At the same time manufacturing is

BUILDING A DIGITAL TWIN FOR ROBOT WORKCELL PROGNOSTICS AND HEALTH MANAGEMENT

December 15, 2021
Author(s)
Deogratias Kibira, Guodong Shao, Brian A. Weiss
The application of robot workcells increases the efficiency and cost effectiveness of manufacturing systems. However, during operation, robots naturally degrade leading to performance deterioration. Monitoring, diagnostics, and prognostics (collectively

Using Simulation and Digital Twins to Innovate: Are We Getting Smarter?

December 15, 2021
Author(s)
Simon Taylor, Bjorn Johansson, Sumin Jeon, Loo Hay Lee, Peter Lendermann, Guodong Shao
Digital Twins have recently emerged as a major new area of innovation. Digital Twins are often found at the core of "smart" solutions that have also emerged as major areas of innovation. Modeling and Simulation (M&S) approaches create a model of a real

Assessing Industrial Robot agility through international competitions

August 31, 2021
