Challenges and Limitations of 3D Printing in the Energy Sector

While additive manufacturing has several benefits to the energy sector, there are many limitations to also keep in mind. They include the following:

Material Limitations

Traditional manufacturing often works with various materials, including metals, plastics, and ceramics. On the other hand, many 3D printers can only work with plastics and low-strength materials. This limitation can be problematic for applications requiring heat-resistant or high-strength materials.

Another limitation is the need for specialized materials for certain energy applications. For example, solar cells require materials with specific electrical and optical properties. Some applications also require specific dimensional accuracy, surface roughness, and mechanical strength. 3D printing may not be compatible with such materials. Therefore, its usefulness may be limited in some applications.

Scaling Up Production

Many 3D printers can be relatively slow. As a result, it may be challenging to produce large quantities of parts quickly and efficiently. While there are 3D printers that can print larger components, they may be limited to specific size ranges. This can be challenging for energy projects requiring parts of varying sizes.

While it may be cost-effective for rapid prototyping and low-volume runs, 3D printing mass production may not be the most cost-effective option. Likewise, the quality of 3D-printed parts can vary depending on printing parameters and environmental conditions. This can lead to inconsistencies in large-scale production.

Regulatory and Safety Concerns

Plastic filament is the most widely utilized material in 3D printing. Although this material is relatively inexpensive and offers excellent quality, its waste contradicts environmental sustainability goals. Furthermore, some 3D printers can emit potentially dangerous nanosized particles into the air.

If not used in a properly ventilated atmosphere, they may have negative health consequences. Aside from environmental considerations, plastic usage in 3D printing also raises energy challenges. 3D printers use much more electrical energy than traditional manufacturing methods. This raises questions regarding energy efficiency and the need for more sustainable 3D printing materials.

Intellectual Property and Standardization

Additive manufacturing has changed the perception of value by shifting it from the object itself to its design. However, not addressing intellectual property (IP) concerns in 3D printing could lead to security issues for the public. It could also lead to liability issues for the designer if anyone can print a pirated or unprotected design.

While 3D printing offers the advantage of producing single items inexpensively, the quality may be inferior to traditional manufacturing. This is partly due to the lack of universal standards and the high cost of high-end machines that produce quality goods. Consequently, many manufacturers and end-users find it challenging to guarantee the consistency of parts or products produced via 3D printing, whether on the same printer or across geographies.

Many manufacturers remain cautious about using additive manufacturing technology without the assurance of consistent quality, strength, and reliability. They perceive the risks of uncertain quality to be too costly for any benefits they might realize.

Renewable 3D Printing Energy Projects

Additive manufacturing has found extensive application in optimizing components across diverse renewable energy sectors. From designing and manufacturing lighter wind turbine blades to developing new designs of nuclear reactor components, 3D printing has played a vital role.

Moreover, it has facilitated the creation of next-generation designs of photovoltaics for use in solar panels. It also helped develop innovative catalysts for hydrogen production and contributed to the decarbonization efforts of several manufacturing firms. Thus, 3D printing has emerged as a crucial technology driving innovation and efficiency in the renewable energy sector.

Here are some notable projects with 3D printing for energy devices:

A. Solar Power

The growth of the solar energy sector is remarkable. This industry benefits from the simplicity of 3D printing for energy generation technologies.

1. Lightweight and Customizable Solar Panels

3D printing has revolutionized solar panel production in multiple ways. The first approach involves applying semiconductor ink onto the wafers of solar panels using 3D printing. This technique allows for the application of the conductive material, made from a combination of boron and polysilicon, on ultra-thin cells that are only around 200 microns thick.

The result is a significant boost in efficiency, as the large specific surface area of the semiconductor ink enhances energy conversion. More remarkably, this 20% improvement in efficiency can be achieved at a lower cost. Meanwhile, 3D printing companies have adopted a different strategy for enhancing solar panel design. We now have high-performance solar panels using a patented volumetric 3D printing technique.

Furthermore, the volumetric 3D printing technique can cure an entire 3D-printed project in a single step. This speeds up the manufacturing process and drives down costs. When used correctly, this technology can make solar electricity more accessible to a larger population. As a result, it is a strong instrument in the transition to a more sustainable energy future.

2. Advanced Solar Cell Designs

Traditional silicon solar cells have several issues, including high production temperatures, environmental impacts, and high manufacturing costs. T3DP, a company that developed a solar cell 3D printing process using perovskite, has improved upon these drawbacks. Perovskite is a semi-conductive material that can be manufactured at lower temperatures, thus reducing manufacturing costs.

The process utilizes volumetric 3D printing to shape the solar material into sturdy hexagon scaffolds. Solar cell technology is vital for ecological sustainability and energy independence, but the current solar cell technology based on silicon wafer technology has shown only incremental progress. Recent research aims to increase photovoltaic efficiency using cheaper materials and novel techniques.

Thin film solar cell development focuses on reducing electron-hole recombination, lowering manufacturing costs, and advancing light management for optical absorption. 3D printing can also improve electric connections, light management, composition/structure of light absorbing layers, and other parts of solar cell modules. 3D printing significantly contributes to the fabrication of solar cells and their components.

B. Wind energy

As we strive towards reducing greenhouse emissions, attention is turning towards wind energy. Consequently, there is increasing research towards creating environmentally friendly wind turbines.

Here are projects to keep an eye on:

1. Efficient Turbine Blade Design

The NREL and the University of Maine have developed methods to improve wind turbine blades and molds, respectively. McGill and Ryerson Universities engineers are turning wind turbine blade waste into a new 3D printable material. Purdue University, RCAM Technologies, and the Floating Wind Technology Company are working on creating lighter and cheaper concrete-based anchors and turbine substructures using 3D printing.

The University of Maine is also working on creating the largest 3D printer in the world to print full-sized molds for wind turbine blades using a cheaper biopolymer. GE has used 3D printing to create lighter turbine blades for their GE9X jet engines and has partnered with COBOD to create 3D-printed wind turbine towers. By optimizing blade models, wind turbines can become more efficient and cheaper to make.

C. Nuclear energy

Attention is turning towards 3D printing for nuclear energy because this technology enables the creation of complex shapes and geometries. This leads to more efficient and effective designs for nuclear components, such as fuel rods and reactor cores.

1. Production of Complex Components

The Russian State Atomic Energy Corporation, Rosatom, is exploring additive manufacturing to produce complex metal components for nuclear products. The company developed its own 3D printers that have undergone successful testing.

It is possible to generate new designs and shapes for batteries by 3D printing them. As a result, they may operate better under certain scenarios. Some researchers are exploring making batteries with 3D structures rather than flat layers. This could make batteries more efficient and last longer.

2. 3D-Printed Fuel Cells and Electrolyzers

Fuel cells and electrolyzers can convert fuel into electricity and electricity into gas for energy storage. Polymer exchange membranes (PEM) and solid oxide cells (SOCs) are two of the most promising technologies.

3D printing has been used extensively in PEM and SOC technologies for depositing thin layers of the main components of the cells, such as electrolytes, functional electrodes, or catalysts, over conventional substrates. This approach enhanced the individual cell performance based on the 3D printing’s ability to use graded compositions or functional layers.

Recent advances in stereolithography and dynamic light processing (DLP) printing of ceramic ionic conductors open the door to more complex shapes. However, in the case of PEM cells, manufacturers only explore complex shapes for the structural components, such as interconnected metallic plates. 3D structured PEM and SOC cells are the next generation of high-performing devices.

E. Fossil Fuels

3D printing technology has the potential to reduce the environmental impact of fossil fuels significantly. Energy-efficient 3D-printed devices help reduce the number of fossil fuels consumed.

1. Enhanced Drilling Equipment

3D printing creates more efficient and durable drilling equipment, which can reduce the fossil fuels needed to power drilling operations. Its ability to create customized and complex parts improves the performance and safety of drilling equipment. As a result, it minimizes the risk of accidents and spills that can have significant environmental consequences. Advanced 3D printing operations use sustainable and recyclable materials, reducing the overall environmental footprint of drilling operations.

2. Innovative Carbon Capture Technologies

Solvent-based absorption is the most advanced carbon capture (CC) technology compared to other processes like membrane separation or cryogenic distillation. However, CC has a few drawbacks, such as high corrosion rates, low CO2 capacity, and the need for high energy input.

One method to reduce energy input is interstage cooling, where the solvent is cooled between the absorber stages using an external heat exchanger. This helps control the heat accumulation generated by the exothermic reaction between CO2 and the solvent. High temperatures can negatively affect the reaction equilibrium and CO2 solubility, reducing the driving force for absorption.

By venting excess heat and keeping the absorber at an optimal temperature, capture efficiency improves, and energy consumption reduces. Additive manufacturing provides new design possibilities for reactors and heat exchangers. This enables the creation of complex geometries and topologies that can help reduce complexities, which is essential for interstage cooling applications.
