Flexibility will allow you to place it anywhere in any direction. Scalability will help you scale performance and production volume depending on customer demand. It will also reduce transportation costs and risks. ?? Circular practices, such as recycling, reusing, and remanufacturing products, extend their lifetime and are an attractive aspect of AM. ??

Additive Manufacturing (AM), commonly known as 3D printing, plays a pivotal role in supporting and enhancing the principles of resilient production within the manufacturing ecosystem. By leveraging the capabilities of Additive Manufacturing (AM) and integrating it into the production ecosystem, organizations can effectively enhance their operational resilience, foster sustainable manufacturing practices, and drive continuous innovation and product development initiatives that empower them to navigate and thrive in the face of market disruptions, competitive pressures, and evolving consumer preferences.

Using AM, companies can achieve a decentralized production and flexible manufacturing system. This can immediately increase the robustness/resilience of the production system because if one additive manufacturing station fails, other stations can flexibly cover the production. Also – as a well-documented and valuable use of AM- 3D printers can produce the spare parts on-site, reducing the machine maintenance time in the case of breakdown. Think about a case that you need to order for spare parts from the part suppliers and wait for a few weeks for the line to back to its normal operation.

- Consider how additive manufacturing (AM) can value add to your manufacturing processes before jumping onto the "bandwagon". - Replacing your parts manufactured from conventional methods will not give you an edge when switching over to AM if there are no product re-design or due considerations. - Simple parts such as washers can be easily produced via conventional subtractive manufacturing (SM) such as stamping and there are no clear benefits in using AM to produce these in masses. - AMs are more suited for complex parts that are difficult to achieve using SM. - AMs are also suitable to replace a few SM processes into 1 integrated part thereby leading to higher quality parts and shorter production time.

Resilient production with AM extends beyond the article by highlighting its potential to reduce lead times and supply chain disruptions. By enabling on-demand production, AM can minimize the need for large inventories, improving resilience against unforeseen disruptions in the supply chain. Additionally, AM's ability to produce complex geometries and lightweight structures can enhance product performance and durability, contributing to overall resilience in manufacturing.

Implementing CPS in resilient production involves several steps. Firstly, assess your production system's current state and identify vulnerabilities. Integrate sensors and data collection points across the manufacturing process to enable real-time monitoring.
