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 />
