Materials engineers play a critical role in the development of new products and materials. Their expertise in materials science and engineering enables them to identify and evaluate the properties of materials, and then develop new materials or modify existing ones to meet the needs of their clients. In doing so, they ensure that the materials developed are safe, reliable, and cost-effective.

The effects of this work can be far-reaching, as it can enable the creation of new products, improved performance of existing products, and more efficient manufacturing processes. Furthermore, their research into new materials can lead to breakthroughs in a variety of industries, including automotive, aerospace, medical, and communications.

Steps How to Become

Earn a Bachelors Degree. To become a materials engineer, you will need to earn a bachelors degree in materials science, engineering, or a related field. Most engineering programs are accredited by the Accreditation Board for Engineering and Technology (ABET).
Pursue Specialization. Some materials engineers specialize in one specific type of material, such as metals, ceramics, or polymers. You may be able to pursue a specialization within your degree program or at the graduate level.
Participate in an Internship Program. Many engineering programs offer internships or co-ops that allow students to gain hands-on experience working with materials and technologies. These programs may provide you with valuable experience that you can use to pursue a career as a materials engineer.
Earn a Masters Degree. Although not required, some employers may prefer to hire materials engineers with a masters degree. You may be able to pursue a masters degree in materials science or engineering.
Get Certified. The American Society for Materials (ASM) offers several certifications for materials engineers. These certifications demonstrate your knowledge and expertise in the field and may help you stand out from other applicants when applying for jobs.
Obtain Licensure. In some states, materials engineers must be licensed in order to practice professionally. To become licensed, you must pass the Fundamentals of Engineering (FE) exam and the Principles and Practice of Engineering (PE) exam.

Material engineers use a variety of techniques to create reliable and capable products. To ensure the quality of materials, they use a range of analytical methods such as failure analysis, destructive testing, and finite element analysis. They also use advanced manufacturing techniques such as additive manufacturing and 3D printing to develop and test prototypes.

In addition, they use sophisticated computer-aided design (CAD) and computer-aided engineering (CAE) software to design products and evaluate them for strength, durability, and performance. By combining these techniques, material engineers can produce reliable and capable products that have the right properties and quality for their intended use.
