Surface roughness plays a critical role in mechanical engineering, especially in how parts interact under stress. A rough surface increases friction, which can be beneficial in applications like brake pads or gripping tools. But in precision machinery, roughness can lead to wear, heat build-up and inefficiency. Measurements of roughness and the type
From aircraft engines to life-saving medical implants, the future is being built one layer at a time. Metal 3D printing allows engineers to design and produce intricate weight-saving designs not previously possible with conventional manufacturing processes. One of its main drawbacks is that parts are left with a rough surface finish, often limiting
Over time, the language underlying the epochs of innovation has consistently been shaped by technological advances. There were steam and factories in the first, electricity and mass production in the second and computers and automation in the third. Today, we are living the Fourth Industrial Revolution defined by big data, robotics and autonomous and
Malta’s science and arts festival Science in the City returns to Valletta on September 26 and 27 with the theme “Past Forward”. The festival, which draws in over 33,000 visitors every year, features over 600 volunteers and 90 organisations creating an “unforgettable celebration of science and art”. This year’s festival encourages visitors to explore
