What Steel Is Made Of: Composition, Elements, and Types

Weerg staff: Aug 5, 2026

What is steel made of? The short answer is: iron and carbon. The complete one opens up a whole world. Steel is a metal alloy composed of over 95% iron, but it's the remaining elements that determine its characteristics.

Understanding the composition of steel means understanding why an S355 behaves...

Threaded inserts for 3D printing: types, choice and installation

Weerg staff: Jul 29, 2026

When a 3D printed component has to be assembled with screws, especially if it's intended to be opened and closed several times during its operational life, the problem of thread durability quickly emerges. The polyamides and polymers used in 3D printing don't, in fact, offer the same threading...

MJF, FDM or resin: which 3D printing technology to choose

Weerg staff: Jul 22, 2026

MJF, FDM or resin? It's the first question anyone with a 3D file to produce asks themselves. Each technology offers different performance, materials, tolerances and costs; choosing the most suitable one directly affects production times, budget and the final result of the project. A wrong choice...

Elongation at break: what it is and why it matters in design

Weerg staff: Jul 15, 2026

Elongation at break is one of the main parameters on material test certificates. It indicates how much a material deforms plastically before breaking under load and is a fundamental parameter for assessing its ductility. For the designer it's an essential piece of data: it makes it possible to...
