New digital approaches leveraging cloud simulations and other advanced analytics are helping manufacturers optimize production lines and end products.
By Lisa Eitel | Executive editor
At the forefront of digital transformation (DX) initiatives is digital manufacturing. Leveraging an integrated computer-based approaches for design, simulation, testing, and production, the use of digital manufacturing could double over the next two years to become a $767B market before 2027. In fact, digital manufacturing is part of a larger trend towards digitization for efficiency and increased ability to customize products.
Common permutations include sensor-based IoT functions, cloud-connected computer-aided design (CAD) and engineering (CAE), and digital twins. Artificial intelligence and machine learning are seeing rapid adoption as well — especially to predict the ramifications of manufacturing process changes and automate decisionmaking.
Common applications include those in smart factories, additive manufacturing, and operations specializing in custom and on-demand manufacturing. Circular-economy initiatives also benefit from digital-manufacturing approaches for the way in which the latter maximizes resource efficiencies.
We recently asked several industry experts about these digital-manufacturing variations and applications. Here’s what those experts had to say.

What technologies of yours are spurring innovation in digital manufacturing?
Kato: CADDi Drawer, designed to support DX in the manufacturing industry, is a unique AI-enabled search platform that centralizes drawings in one platform regardless of format with proprietary image-analysis algorithms (with a patent pending). Through high-precision similarity searches on the most important digital asset in manufacturing, drawings, it enables cost reduction in design, procurement, and production departments.
CADDi Drawer is not merely a drawing management tool; it serves as a powerful knowledge retention solution. In procurement, essential data is often scattered across decentralized databases and the minds of employees, resulting in a significant knowledge drain when employees leave. Using AI-enabled shape recognition, CADDi Drawer centralizes drawings and cross-references them with purchase histories, effectively preserving crucial knowledge and reducing the time it takes to search for drawings by up to 80%.
Wierzchowski: We’re enhancing our overall ecosystem by integrating manufacturing-related functions within the shop floor control system. This integration is facilitated by the adoption of a low-code programming language, which enables us to efficiently scale and increase our adaptability to meet the unique needs of our end users. The success of this modernization stems from the business process management system we established four years ago, which catalyzed the adoption of Jabil’s enterprise process standards.
We’re also advancing our enterprise capabilities in the fields of computer vision, knowledge and language processing, and analytics and intelligence. The Jabil strategy for rapid industrialization and deployment of technologies leverages a modular architecture composed of various technologies. These can be combined to fulfill precise customer needs. As a result, we’re cultivating new capabilities to analyze data; address failures in realtime; and anticipate as well as prevent potential failures before they occur.
Any new offerings leveraging AI?
Kato: CADDi is addressing critical issues in the manufacturing industry, offering innovative solutions for procurement and data management, including CADDi Drawer — a SaaS solution that turns drawing libraries into searchable assets for manufacturers. By allowing easy and precise searches for drawings (critical digital in manufacturing) CADDi Drawer helps manufacturing companies save costs in their design, procurement, and production departments.
As a global manufacturing solutions provider servicing 600-plus supply chain partners fabricating custom metal partners, CADDi realized a pain point every customer seemed to have — accessing past drawings was an absolute nightmare. So, the team developed a proprietary image analysis algorithm to help clients digitize and search for drawings much faster and more accurately than any other platform in the marketplace. CADDi uses AI to streamline and digitize the procurement process.
Realizing the impact of this solution, the team launched CADDi Drawer as a SaaS to help manufacturers procure parts for less by reducing pricing inconsistencies and fabricators win more deals by semi-automating their quotations. CADDi Drawer reduces drawing search time by 80% and overall procurement costs by 30%.
What makes CADDi unique in the industry is that is designed with the manufacturing industry and its needs top of mind. If you imagine AI as a child that continues to learn, CADDi’s AI has been born and raised in manufacturing. It doesn’t go off on tangents in other disciplines. It simply knows manufacturing in and out.
Lemire: Our machining centers (and Industry 4.0 implementation of intelligent digital technologies in our manufacturing and industrial processes) are key to satisfying future gear demand for robotics applications. Soon, we’ll be collecting data via next-generation computing for a large digital database to allow AI modeling of errors in backlash.
For us, AI is also key to supporting predictive maintenance and reducing manufacturing costs. Motion control is evolving to integrate AI learning and predictive models. Electromechanical systems are now more integrated with the IoT. Supporting the robotics industry, carefully documenting the characteristics and unique DNA of next-generation motors and gearmotors will allow for better performance and predictive maintenance.

Describe some recent use of digital twins or digitization.
Wierzchowski: By creating a detailed digital replica of our sites, we’ve enhanced our overall asset use, minimized excess inventory, and improved the flexibility of transferring machines across manufacturing sites.
Rangarajan: The next step in the evolution of 3D printing will be the implementation of digital twins — a virtual replica of 3D printers and their operations. Every serial number has its unique live model that represents the machine state. These digital twins are created leveraging physics models of the underlying process as well as telemetry data supported by AI and ML techniques. Digital twins support the creation of continuous, automated, and efficient 3D-printer operations via adjustment and optimization of build and print parameters. This in turn maximizes uptime and reduces variability across machines and within a given build. Digital twins also contribute to efficient and scalable systems for high production.
As more processes along the production lifecycle become automatized, manufacturing capabilities will expand beyond the constraints of labor costs — extending production into night and weekend shifts so costly to manufacturers. With lower total cost of ownership (TCO) for 3D-printing technologies, access can expand to new verticals and prompt a new wave of manufacturing marked by lights-out factories.
Wierzchowski: We initially implemented digital-twin technology at Jabil for the design of complex automated stations. This technology has since advanced to encompass factory-floor design to give us high-performing production lines, streamlined material flow, and reduced manufacturing costs. The comprehensive view of the manufacturing floor provided by digital twins has also facilitated timely maintenance scheduling so crucial for maintaining uninterrupted production.
Kato: Over the past year, AI has been increasingly utilized in optimizing machine and circuit designs, with innovative applications like CADDi Drawer standing out. CADDi Drawer represents a significant advancement in this field by digitizing historical drawings, which includes both design elements and documented quality issues encountered during manufacturing. This comprehensive digital archive enables engineers to learn from past experiences, focusing on innovation rather than reiteration.
The AI in CADDi Drawer goes beyond mere digitization. It analyzes various aspects of the drawings, such as the shapes of parts, to identify similarities in designs. This capability allows for the standardization of parts where feasible, which in turn enhances production efficiency and cost-effectiveness. By standardizing parts based on historical data and design similarities, organizations can streamline their manufacturing processes, reduce costs, and improve overall product quality.
In essence, tools like CADDi Drawer embody a shift in design philosophy, leveraging AI to convert historical data into actionable insights. This approach helps in avoiding repetitive issues, fostering innovation, and cost of production of machine and circuit design.
