Markforged Composite Strength compared to Aluminium Strength

November 13, 2023

The comparison between the strength of Markforged composite materials and traditional aluminium is a topic of significant interest and importance in engineering and manufacturing. Markforged's innovative composite materials offer a unique value proposition and have the capability to enhance the performance of existing aluminium parts. Understanding the respective strengths of Markforged composites and aluminium is crucial for engineers and designers seeking the most suitable materials for their specific projects. Let's delve into the comparison of strength between Markforged composites and aluminium:

Each type of Markforged fiber provides specific advantages to the parts. For example, Carbon Fiber offers high strength, Kevlar enhances toughness, and Fiberglass provides an economical option for increasing part strength. HSHT Fiberglass excels in high-temperature applications. Markforged composite parts reinforced with Carbon Fibre, when designed and manufactured correctly, can be significantly lighter than their aluminium counterparts while maintaining comparable or superior strength. This makes composites ideal for applications where weight reduction is crucial, such as in aerospace and automotive components.

On the other hand, aluminium is a relatively lightweight metal with good strength properties. It is a versatile material suitable for a variety of applications, with the advantage of being machinable to tight tolerances. Aluminium is commonly used in industries where a balance between strength and weight is essential. Although aluminium has a respectable strength-to-weight ratio,composites can often achieve higher specific strengths (strength per unit weight). Additionally, aluminium has a significantly higher heat deflection temperature than Markforged composites, making it a more suitable choice for applications that require resistance to high temperatures.

In summary, Markforged composites, particularly those reinforced with continuous fibres, offer exceptional strength properties that can compete with or even surpass aluminium in specific areas. However, the choice between composites and aluminium depends on the specific requirements of the application, including factors such as weight constraints, environmental conditions, and cost considerations. Engineers and designers must thoroughly evaluate the performance characteristics of both materials to make informed decisions for their particular projects.
