Cynthia Wirth, a 3D printing expert at Siemens Energy, finds satisfaction in shaping the future of sustainability. Through additive manufacturing, the company is revolutionizing turbine blade production, reducing material waste by up to 65%. With over 15,000 components produced annually, these advanced 3D-printed parts are used in Siemens’ turbines and sold to external customers.⁴ These technologies are good for the environment and allow engineers to create complex designs that were impossible to manufacture using traditional methods.

In manufacturing, robotics automates complex processes, enhancing safety and productivity. Boston Dynamics, a company at the forefront of robotics innovation, has developed robots to perform tasks in warehouses and hazardous environments. For example, the company’s robot, Stretch, handles warehouse work for shippers such as Maersk, DHL and Gap. Spot, the dog-shaped robot, assists first responders and conducts about 200,000 industrial inspections per quarter. There are 1,500 of these robots working across customer sites.⁵

Meanwhile, 3D printing, also known as additive manufacturing, has opened new avenues in product development by enabling rapid prototyping and reducing material waste. Siemens, for instance, uses additive manufacturing to create custom turbine blades for power generation, which enhances performance and efficiency while minimizing material usage.⁵

Advanced Materials Engineering

Advanced materials are revolutionizing modern engineering by driving the development of stronger, lighter and more versatile products across industries. These include composites. nanomaterials and smart materials.

Advanced Composites

In advanced composite materials, two or more materials with different chemical or physical characteristics are combined. Because they have unique properties, such as heat resistance, increased strength and lower weight, engineers can use them to develop advanced structures and technology:⁶

• The aerospace industry uses carbon fiber, fiberglass and other advanced composites to build stronger, more lightweight aircraft
• The automotive sector uses carbon fiber to produce faster, more fuel-efficient, lighter-weight vehicles such as racecars⁷
• The renewable energy industry uses advanced composites to make longer, lighter wind turbine blades that adapt better to changing wind speeds, boosting energy capture more efficiently than traditional blades⁸

Nanotechnology and Nanomaterials

What if we could use nanotechnology to develop pharmaceuticals that precisely target cancer cells, improving treatment outcomes? How about leveraging nanomaterials for environmental solutions, such as binding toxins for efficient cleanup during disaster remediation?^9,10

Nanotechnology refers to the science and techniques used to manipulate materials at the nanoscale—typically between 1 and 100 nanometers—to create new tools, devices and systems. Nanomaterials, on the other hand, are the materials themselves engineered at this tiny scale.¹⁰ While nanotechnology promises innovation, it also raises environmental and health concerns.

According to the National Institute of Environmental Health Sciences, even familiar materials like silver can pose health risks when engineered down to nano size. We can inhale and ingest particles that small, which can then be absorbed into the body. Fibrous carbon nanomaterials, much like asbestos, have been known to cause lung swelling.¹⁰ Scientists haven’t yet developed methods for detecting levels of nanoparticles in the air, which could mean that humans are vulnerable to unintentional, unsafe exposure.

Smart Materials

According to the National Aeronautics and Space Administration (NASA), smart materials can change properties in response to stimuli such as temperature, light or pressure.¹¹ For example, NASA has found a way to create adaptive aircraft wings that respond to environmental conditions using shape memory alloys (SMAs). These substances are remarkable in that, no matter how much they are stretched or heated, they always return to their original shape.¹²

This materials science revolution has led scientists to develop self-healing and self-sustaining materials. The healthcare industry could then use these substances to create electronic skin, device implants and wearable biosensors.¹¹

Eco-Friendly Engineering Technologies

As the global green technology market is set for rapid growth—from $17 billion in 2023 to $112 billion by 2032—there will be new opportunities for innovation.¹³ This quickly growing sector spans energy-efficient appliances and vehicles, waste management, renewable energy and green building materials. Engineers will be challenged to create systems that meet technical and environmental standards: Balancing the two is easier said than done.

Consider the case of Tesla’s Gigafactory in Germany. While praised for advancing electric vehicle production, it has stirred controversy over its environmental impact, particularly related to water usage and pollution. Tesla claims it recycles nearly 100% of its industrial water and uses 33% less water per vehicle than the industry average, but critics point to the environmental toll of lithium mining for batteries.¹⁴ This case highlights the complex role engineers play in balancing technological progress with environmental responsibility, raising questions about sustainable practices in large-scale manufacturing.
