Changing Industry Norms with Additive Manufacturing

Additive manufacturing (AM), also known as 3D printing, is making waves across industries by fundamentally altering how products are designed, produced, and delivered.

While its application for cutting costs, creating complex geometries, and rapid prototyping is widely acknowledged, there’s a more profound shift occurring beneath the surface.

Additive manufacturing is not merely another tool in the production toolbox; it has become a catalyst for changing long-standing norms and practices within the manufacturing industry.

This post will explore how AM is reshaping conventions in ways many have overlooked.

Read on to uncover how additive manufacturing transforms supply chains, redefines business models, and fosters sustainability in ways unmatched by traditional methods.

Additive Manufacturing Beyond Prototyping

For decades, the manufacturing industry has adhered to traditional workflows, focused on mass production, logistics-heavy supply chains, and one-size-fits-all design approaches. However, additive manufacturing is fundamentally challenging these norms.

Many blogs and articles focus on additive manufacturing’s widely known abilities like rapid prototyping and cost efficiency for low-volume production.

However, this raises a critical question: Can AM break away from simply being viewed as a prototyping tool and redefine entire industry standards?

The answer lies in three key areas that industries must focus on more carefully to unlock the full potential of AM.

1. Disruption of Traditional Supply Chains

One of additive manufacturing’s most revolutionary contributions lies in transforming supply chains. Traditional supply chains are fragmented and reliant on global networks for raw materials, manufacturing, and distribution.

They also incur significant lead times and storage costs.

How AM is redefining supply chains:

Distributed Manufacturing: Additive manufacturing enables production at or near the point of demand. Businesses can replace large, centralised facilities with decentralised hubs, cutting down delivery times and reducing the carbon footprint of transportation.
On-Demand Production: Additive manufacturing does away with the need for extensive stockpiles. Components can be created precisely when needed, reducing inventory costs and waste.
Simplified Logistics: AM eliminates multiple production stages by consolidating entire assemblies into single parts. For instance, rather than shipping separate components, a single design file can be transferred digitally and printed at the end location.

Application Example

Consider the aerospace industry, where additive manufacturing is already enabling the production of complex, lightweight parts at specialised hubs.

Some companies have adopted distributed manufacturing models, whereby spare parts are printed near operational sites as needed, reducing downtime and inventory overheads.

2. Enabling Hyper-Customised Business Models

The standardisation seen in mass production often creates inefficiencies where products are poorly matched to customer needs. Additive manufacturing challenges this paradigm by enabling ultra-customised solutions.

The power of customisation through AM:

Bespoke Products: Additive manufacturing allows a move away from “design for manufacturing” to “manufacturing for design”. Products can be shaped and customised to the unique preferences or requirements of individual customers without cost penalties.
Personalisation at Scale: The healthcare industry is a prime example where bespoke implants and prosthetics crafted via AM ensure better patient outcomes while keeping costs low. Similarly, the footwear industry has seen brands create customised shoe soles tailored to a customer’s foot.
Flexible Production at Lower Costs: Unlike traditional methods, AM removes the steep setup costs associated with tooling or moulds, making small-batch or one-off production viable.

Emerging Opportunities

Industries such as automotive and jewellery are already leveraging these capabilities. For instance, automotive manufacturers are offering limited-edition, custom interior parts printed using AM, adding value to their high-end product lines.

3. Fostering Sustainability in Manufacturing

Few discussions on additive manufacturing adequately address its potential to drive the shift towards sustainable industrial practices. AM’s role here is pivotal due to its capacity to minimise waste and optimise resource use.

Sustainability through AM:

Reduced Material Wastage: Unlike subtractive manufacturing, which carves parts out of large blocks of material, AM uses only the material required to build a component layer by layer, leaving little to no waste.
Use of Recycled and Renewable Materials: AM also enables the use of eco-friendly materials. Research shows that polymer recycling and advancements in biodegradable materials are expanding AM’s environmental impact.
Energy Efficiency: By consolidating parts, AM reduces manufacturing energy expenditure. Furthermore, its ability to produce lighter components benefits sectors like aerospace, where weight reduction leads to lower fuel consumption.

Real-World Example

A recent study highlighted how turbine blade production for aircraft via powder-bed fusion reduced raw material waste by over 60% compared to traditional methods.

4. Empowering Localised Innovation Ecosystems

One of additive manufacturing’s most understated impacts is its empowerment of localised innovation ecosystems. By decentralising manufacturing capabilities, AM reduces barriers to entry for small businesses and innovators.

How this drives progress:

Democratisation of Manufacturing: Access to low-cost 3D printers allows start-ups and independent innovators to design and produce new products without requiring expensive infrastructure.
Reduced Dependency on Global Supply Chains: AM enables resilience in regions where access to traditional manufacturing facilities may be limited. This is especially vital during crises, such as COVID-19, when global supply chains were disrupted.
Educational Opportunities: Educational institutions can incorporate AM to foster a culture of hands-on learning and innovation, preparing the next generation of engineers for the demands of Industry 4.0.

A Case Study in Action

During the peak of the COVID-19 pandemic, 3D printing hubs distributed in multiple regions played a crucial role in producing ventilator components when global supply chains struggled to keep up with demand.

5. Future Outlook – From Niche Technology to Mainstream Adoption

The transition of additive manufacturing from a niche technology to a mainstream industrial process hinges on three critical factors:

Material Innovation: Broader adoption will depend on the availability of cost-effective, high-strength materials offering consistent performance.
Regulatory Standardisation: Standardisation across AM processes and materials will be crucial to enabling widespread adoption across industries.
Integration with Traditional Manufacturing: Rather than replacing traditional methods, additive manufacturing is likely to work in tandem with them, creating hybrid factories better equipped for evolving demands.

Bridging the Gap

Engineers and manufacturers need to explore combining AM with predictive analytics and AI-driven design optimisation tools to unlock its full potential. Teams need to foster multi-disciplinary collaboration to realise highly efficient and sustainable workflows that blend AM seamlessly into traditional setups.

Unlocking the Future of Additive Manufacturing

Additive manufacturing is no longer constrained by its early application in prototyping. Today, it enables decentralised production, better customisation, and sustainable practices that redefine the future of manufacturing. Integrating AM into your manufacturing processes doesn’t just offer you a competitive edge; it positions your business as a forerunner in the era of Industry 4.0.
