The Best Free Tools & Platforms to Practise Materials Science Skills in 2025/26
Materials science is one of the most exciting multidisciplinary fields today, sitting at the crossroads of physics, chemistry, engineering, and data science. It underpins advances across sectors — from developing new semiconductors for electronics, to creating sustainable polymers, to innovating alloys for aerospace and defence.
In the UK, demand for materials scientists is growing rapidly. Employers are looking for candidates who not only understand theoretical principles, but can also demonstrate practical skills in modelling, simulation, data analysis, and design.
The challenge? Commercial materials software packages can cost thousands of pounds. Fortunately, a wide range of free and open-source tools make it possible to practise materials science without financial barriers. These platforms allow you to explore everything from atomic-scale quantum simulations to computer-aided design, visualisation, and machine learning for materials discovery.
This guide highlights the best free tools and platforms to practise materials science skills in 2025. Each section explains what the tool does, why it’s useful, and how you can leverage it to build portfolio-ready projects and prepare for a career in the sector.
Why Practising Materials Science Skills Matters
Like many technical fields, materials science has a significant gap between theory and practice. Employers want to see more than exam results — they want to know you can apply methods in real-world contexts.
Hands-on practice with free tools allows you to:
Model materials at different scales — from atomic to structural.
Simulate properties and behaviours — thermal, mechanical, electronic.
Work with real datasets from open repositories like Materials Project or NOMAD.
Design and test structures using CAD and finite element analysis.
Explore machine learning applications in predicting new materials.
Showcase portfolio projects on GitHub or in job applications.
By practising, you’ll not only master technical methods but also develop the ability to communicate results clearly — a skill employers in the UK highly value.
