Manufacturing’s<br />

Great<br />

Convergence:<br />

Most manufacturers’ concerns revolve around figuring out how to improve the supply of raw<br />

materials and meet demand while controlling both costs and quality. For many manufacturers,<br />

the solutions to these issues have emerged in the application of the technologies known<br />

collectively as Industry 4.0.<br />

INDUSTRY 4.0<br />

The costs associated with adopting robots continue to decline,<br />

making them more accessible even for small and medium-size<br />

businesses due to rising labour costs. The unit cost is expected to<br />

drop 50% to <strong>60</strong>% by 2025. A decrease in material and technology<br />

costs, improvements in IIoT and cloud infrastructure, as well as the<br />

ease of connecting robots to existing systems all allow for easier<br />

and cheaper transitions for manufacturers.<br />

The introduction of co-bots has made advanced robotics more<br />

accessible to enterprises of all sizes and significantly reduced the<br />

required upfront investment, making it the perfect choice for mass<br />

adoption in the manufacturing sector.<br />

Advanced robots, especially for material handling, are undergoing<br />

a revolution along with advances in autonomous driving and battery<br />

life with automatic guided vehicles. This trend is coupled with pickand-place<br />

robots for simple operations on assembly lines.<br />

Wearables<br />

Wide adoption of wearable technologies across industries has<br />

intensified competition and driven innovation and investments<br />

across the ecosystem. The global industrial wearables market is<br />

expected to reach $8.4-billion by 2027, up from $3.8-billion in 2019.<br />

Cost-effective and more sophisticated AR/VR headsets from<br />

original equipment manufacturers such as Sony, Google, Microsoft,<br />

Apple, Facebook and HTC have emerged in both the consumer and<br />

industrial spaces. AR and VR software developers now implement ML<br />

and AI in apps for wearables, allowing systems to see and analyse<br />

anything in their fields of vision.<br />

The Industrial Internet of Things<br />

The IIoT uses connected assets to provide visibility and transparency<br />

in factory operations. A typical smart factory IIoT ecosystem includes<br />

sensors, connected devices, networking and connectivity solutions,<br />

edge and cloud infrastructures, IIoT platforms and gateways and<br />

analytics applications. This ecosystem is rapidly advancing and<br />

becoming more sophisticated, resulting in the rapid deployment of<br />

MANUFACTURING<br />

new IIoT applications and services to improve quality and productivity.<br />

According to Gartner, 50% of industrial enterprises will use IIoT<br />

platforms by 2025 to improve factory operations, up from 10% in<br />

2020. The global IIoT market stood at $216.1-billion in 2020 and is<br />

expected to reach $1.1-trillion by 2028.<br />

The emergence of 5G-enhanced IoT applications is helping<br />

manufacturers realise their vision of Industry 4.0 more than any<br />

other development.<br />

Artificial intelligence<br />

AI is still a nascent technology in manufacturing, but recent<br />

breakthroughs in ML techniques (deep learning) have sparked<br />

high expectations for future applications. Cognitive modes such as<br />

natural language processing, computer vision, pattern recognition<br />

and reasoning with ML techniques are widening the array of potential<br />

applications for manufacturers.<br />

This growth is being driven by the digitisation of data, rapid<br />

growth in IIoT data sources, hardware developments and the<br />

democratisation of AI and data, among others. Relative to other<br />

Industry 4.0 technologies, the hardware cost for AI is small, and<br />

most of the investment is spent on developing and rolling out the<br />

software solution. Consulting, maintenance and training services<br />

do incur additional costs.<br />

Advanced analytics and ML create tremendous value in applications<br />

where yield and process waste is a big issue, especially in process<br />

industries where even a percentage point of improvement is in the<br />

millions. While the technology continues to advance, many firms<br />

struggle to extract the full value.<br />

THREE CHALLENGES<br />

The shortage economy<br />

Many global manufacturers and distributors have been unable to<br />

achieve their desired outputs because of a shortage of raw materials<br />

or other components, a lack of resources to run their operations or<br />

limitations to internal capacity due to asset or space constraints.<br />

These challenges must be addressed through better planning,<br />

installing more long-term capacity and improving the allocation of<br />

resources. However, when manufacturers look at what they can do<br />

immediately, they should seek to answer one key question: How do we<br />

make better use of the resources we do have? This requires enabling<br />

DEVELOPMENTS IN INDUSTRY 4.0<br />

3D printing<br />

3D printing (3DP) is getting faster and stock material prices are falling.<br />

Even though 3DP’s contribution to manufacturing is minuscule (about<br />

0.1%) compared with traditional manufacturing methods, the growing<br />

number of applications and demand for custom manufacturing will<br />

continue to expand the market. One major driver of the increasing<br />

speeds for prototyping in a production environment is lasers, which<br />

enable faster sintering or bonding of the build.<br />

The emergence of 5G-enhanced IoT<br />

applications is helping manufacturers<br />

realise their vision of Industry 4.0.<br />

3D printers will continue to evolve, using artificial intelligence<br />

(AI) and machine learning (ML) to improve build rates and quality<br />

while continuing to push the break-even point with traditional<br />

processes. The focus will be on producing cost-effective metal<br />

powders to become even more cost-competitive.<br />

Advanced robotics<br />

The adoption of advanced robotics in manufacturing has steadily<br />

accelerated, with the pandemic’s unique challenges adding a catalyst<br />

for the transformation. The global average industrial robot density<br />

in manufacturing reached an all-time high of 126 robots per 10 000<br />

employees in 2021, compared with 66 robots per 10 000 workers in<br />

2015. Advancements in technology platforms such as the Industrial<br />

Internet of Things (IIoT) and connected systems are upgrading<br />

the functionality of robots and paving the way for collaborative<br />

robots (co-bots).<br />
