When designing components for sectors such as automotive, electronics, industrial, UAV, or medical,materialselection cannot be based solely on mechanical properties. It is essential to also consider safety regulations and certifications, such as UL94 and the so-called Blue Card (UL Yellow Card).

Over the past few weeks, we have published four articles dedicated to four companies that chose SLA resin 3D printing to solve real problems: not to look good in a press release, but to reduce costs, shorten development times and produce better parts.
Today, it is time for the recap. Weerg’s SLA...

If you are an engineer tasked with choosing between SLA and FDM, avoid comparisons based on opinions. This guide is founded on concrete data: tolerances measured to the micrometre, impermeability tests carried out by a university laboratory, and the use of these technologies by Ford in the...

If you think of SLA resin, you probably picture small translucent models, aesthetic prototypes, or display miniatures. It's a widespread perception — and a completely mistaken one.
In recent years, the applications of SLA resin have expanded dramatically. Thanks to technical materials such as Rigid...

The galvanisation of an SLA resin print triples its breaking load, quadruples its stiffness, and improves flexural resistance by nearly 10 times. This is the finding that convinced Volkswagen to choose SLA 3D printing — rather than a metal printer — to produce the wheel covers for the "Type 20"...

Metrology is the science of measurement and represents one of the fundamental pillars of modern industry. Without precise and reliable measurements, it would be impossible to guarantee product quality, compliance with tolerances, and the repeatability of manufacturing processes.
In particular, ...
