Biggest change in manufacturing since the industrial revolution?
Probably the biggest change since the industrial revolution is currently ongoing in manufacturing technologies. You may think that 3D printing has nothing to do with your business, but is that really the case?
3D printing is expected to change the production of goods. It is not only going to automate and digitalise manufacturing, but also enable us to build better products and new applications.
What is 3D printing?
While the traditional manufacturing is mostly based on processes where materials are removed, 3D printing adds thin layers of material until the desired product is created. This is also called additive manufacturing. The method is applicable to various raw materials, including metals, ceramics, rubber and plastic. So far, it has mostly been used for fast prototyping, but the number of commercial products is increasing all the time. Printing is based on computer aided design (CAD) models, which makes the manufacturing process part of digital businesses.
The benefits of 3D printing include time to market, fast ramp-up of production, agile manufacturing, ability to avoid some of the expensive phases of the traditional production process, customisation and personalisation of products, and high-end production.
However, the capability to produce something better, or something that was not possible before, should be key for renewal.
It seems that technology evolution is beating the limitations one at a time.
There are still some limitations to be compensated, such as durability and other material related characteristics of the printed components, printing time, and the price of raw materials and commercially available printing equipment. However, it seems that technology evolution is beating the limitations one at a time.
In addition to rapid prototyping, 3D printing is today used commercially in medical applications such as implants, jewellery, decorations, and mobile phone covers.
The aerospace industry is a strong believer of 3D printing, seeing it as an opportunity for less costly tooling to build more durable and lighter aircraft, which would save substantial amount of energy during the flights.
Trends like design and personalisation are clearly drivers for 3D printing. Also sustainability, local production and open innovation are driving future manufacturing towards 3D.
Is 3D printing going to change the world cargo flows?
The biggest change induced by 3D printing may happen in global value chains and logistics. Nobody knows what is really going to happen, but it is wise to keep the eyes open and be ready for change.
Globalisation has been a major industrial trend in which low labour costs have driven companies to set up their production sites in low cost countries, thus creating growth of cargo shipping between continents. The balance between transportation and labour cost may change. A new trend in the future may be glocalisation, where the global business is supported by local 3D production that optimises the business through speed, quality or personalisation.
Part of the global production may shift back to wealthy countries, leading to decreased shipping volumes of goods between Asia and other continents, at the same time increasing the shipping volumes of raw materials between continents.
Another potential change scenario is the optimisation of cost and operational efficiency of global logistics, once the local production of spare parts becomes technically and economically feasible. The local printing ecosystem may produce the critical spare parts quickly on a need basis, thus minimising warehousing needs. This would change service parts logistics and even decrease downtime due to better availability of critical spare parts. This would also create new roles in the value chain: CAD model creation for spare parts, local printing business and digital distribution network of the CAD models.
The product development speed, cost and quality may be optimised by fast prototyping, as well as design of parts that could not be manufactured before. For example, producing one part instead of assembling several parts together would optimise the production process. This would enable production of personalised solutions for cabins of the cargo handling equipment in order to optimise the fit for purpose.
Miniature models create another opportunity for our industry. Printed miniature models of cargo handling equipment ease the R&D effort while seeking justification between different alternative models. On the other hand, printed miniature model of the entire terminal layout could make terminal development cooperation between solution provider and the terminal operator more tangible, for example, by helping both parties to see the major operational bottlenecks easier. Miniature models would also be interesting tools for marketing and communication purposes.

What’s in it for me? There’s a possibility for change around us. It’s up to you to start taking your role in the changing value chain before others make the decisions for you.
