Laser processing offers numerous advantages over conventional manufacturing methods. For instance, it can reduce lead times, improve quality standards, and decrease material wastage. 

Due to such benefits, the use of laser processing applications is increasing. According to Precedence Research, the worldwide laser processing market is projected to double. It is expected to grow from $20.64 billion in 2022 to approximately $44.09 billion by 2032.

Understanding Laser Processing Solutions

According to Novanta Photonics, laser processing is a manufacturing technique that uses a laser to melt, cut, and mark materials. It can be used to produce goods with complex geometries and surface textures. Laser processing technology has existed since the 1970s, but it's only recently become widely available as an affordable solution.

Almost every type of manufacturing company can use laser processing. Recently, the fabrication sector has adopted ultra-high power fibre lasers in the 10-40 kW range for cutting. These high-efficiency lasers reduce operating costs and also lower the cost per part. 

Key Advantages of Laser Processing in Manufacturing

Laser processing has many advantages over traditional manufacturing, including:

• Increased speed: Lasers can cut, drill, and bore through materials at extremely high rates. These speeds can be further enhanced by using multiple lasers in conjunction with one another. This means your manufacturing processes will be much more efficient than before you started using lasers in your facilities.
• Improved surface finish quality: Laser processing can produce high-quality finishes on products. That's because they create smooth surfaces without any tool marks or burrs left behind on the piece they are working on.
• Versatility: Lasers can be used on various materials, including metals, plastics, ceramics, and composites. This versatility makes laser processing suitable for multiple manufacturing applications.
• Non-contact process: Since lasers are non-contact tools, there is minimal wear and tear. This results in a longer equipment lifespan and reduced maintenance costs compared to traditional mechanical tools.
• Reduced heat affected zone: Laser processing can be highly controlled, minimising the heat transferred to the surrounding material. This is critical for materials sensitive to heat, reducing the size of the heat-affected zone and minimising distortion.
• Cost-effective: Since lasers are non-contact tools, there is less wear on tooling, resulting in lower tooling costs over time. Laser processing can be highly efficient, minimising material waste and reducing production costs.

Facilitating Innovation in Manufacturing

Laser processing is a good way to innovate. It can be used to create new products or improve existing ones. Here are some ways in which laser processing solutions can facilitate innovation in manufacturing.

Customisation and Personalisation

Laser processing solutions can facilitate innovation in the manufacturing industry through customisation and personalisation. Customisation refers to making changes to a product, while personalization refers to making each unit unique. These aspects are essential for innovation because they allow manufacturers to create more efficient products that fit specific needs.

Laser processing allows you to customise your products by changing their shape or size quickly and easily. For example, simply use lasers if you need a part smaller than your current product. They'll allow you to cut the product precisely to decrease its weight significantly. Thus, customers can carry your products without breaking their backs.

Another way laser technology improves customisation is through personalisation. It can help engrave text onto any surface, such as glassware or other decorative items like cups or plates. This can make the product personalised for individual customers.

Design Flexibility

Laser processing is a flexible and powerful solution that can be used for many different applications. The ability to create new designs, customise products, and achieve high-quality results makes it an ideal choice for manufacturers looking to innovate.

Here are several ways in which laser processing contributes to innovation in manufacturing:

• Precision and accuracy: Laser processing provides unmatched precision and accuracy. It is so precise that the chances of sharp edges, protrusions, and other irregularities are reduced. This, in turn, lessens the number of tasks to be performed in secondary deburring processes. Laser processing allows manufacturers to create intricate and complex designs with minimal margins of error.
• Material versatility: Laser systems can be tailored to work with various materials, including metals, plastics, ceramics, and composites. This versatility enables manufacturers to explore novel material combinations, fostering product design and performance innovation.
• Micro-machining and miniaturisation: Laser technology enables micro-machining, allowing manufacturers to create extremely small and intricate components. This capability is essential in the miniaturisation trend in various industries, from electronics to medical devices.
• Customisation and personalisation: Laser processing facilitates mass customisation, where each product can be tailored to individual specifications without sacrificing production efficiency. This is particularly relevant in industries like automotive and consumer goods.
• Rapid prototyping: Laser systems are integral to rapid prototyping processes, enabling manufacturers to quickly iterate and test designs. This accelerates the product development cycle, fostering innovation by allowing for faster exploration of ideas.
• Additive manufacturing (3D printing): Laser-based additive manufacturing, commonly known as 3D printing, is transforming the manufacturing landscape. It allows for creating complex geometries that were previously impossible or highly impractical. This is especially beneficial in the aerospace and healthcare sectors.
• Surface modification and finishing: Laser processing is used for precise surface modification and finishing, enhancing products' functional and aesthetic qualities. This is crucial in industries such as automotive, where surface properties are vital for performance and appearance.
• Reduced waste and environmental impact: Laser processing is a highly efficient and controlled manufacturing method, reducing material waste. The focus on sustainability and environmental impact drives manufacturing process innovations, and laser technology aligns well with these goals.

Applications in the Manufacturing Industry

Laser processing solutions have become integral to the manufacturing industry, offering a versatile and precise method for various applications. One key area where lasers excel is in material cutting. With exceptional accuracy, lasers can cut through multiple materials, including metals, plastics, and composites. This capability is particularly valuable in industries such as automotive and aerospace, where intricate parts demand high precision.

In addition to cutting, laser welding is another critical application in manufacturing. Laser welding provides a non-contact and localised heat source, enabling the precise joining of materials. Laser welding is mainly used in the automobile and aeronautical sectors. It increases production rate, reduces production cost, and has a high power density of around 1 MW/cm2.

The manufacturing industry also benefits from laser engraving and marking solutions. Lasers can etch permanent marks on various surfaces, adding serial numbers, logos, or other identifiers with precision and speed. This is crucial for traceability and branding purposes, enhancing quality control and facilitating product identification throughout the supply chain.

Furthermore, manufacturing processes employ laser ablation for surface modification and cleaning. This technique can selectively remove layers or contaminants from materials without causing damage to the underlying substrate. Applications range from cleaning delicate electronic components to preparing surfaces for adhesive bonding.

Rapid prototyping and additive manufacturing have also embraced laser technology. Laser sintering and melting processes are commonly used in 3D printing to build intricate components layer by layer. This enables the creation of complex geometries and facilitates the production of prototypes and customised parts cost-effectively.

Lasers play a crucial role in measurement and inspection in quality control. Laser-based sensors and scanners can quickly and accurately assess dimensions and detect defects in manufactured products. This contributes to maintaining high-quality standards and reducing the likelihood of faulty items reaching the market.
