SLA Resin: 4 case studies that prove why it’s worth twice the price

Weerg staff: May 5, 2026

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...

5 Applications of SLA Resin

Weerg staff: Apr 21, 2026

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...

SLA Resin 3D Printing: Why Volkswagen, Ford and Unilever Use It

Weerg staff: Apr 14, 2026

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: What It Is and How It Is Used in Industrial Manufacturing

Weerg staff: Mar 12, 2026

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, ...

Metallographic Analysis: Microstructure and Quality Control

Weerg staff: Mar 4, 2026

Metallographic analysis is a fundamental technique used to study the microstructure of metals and alloys. By observing a specially prepared sample under a microscope, it is possible to assess:

• material quality
• internal defects
• heat treatments
• phase distribution
• grain size
• causes of fracture

It is...

Thermoplastic and Thermosetting Polymers: Differences and Uses

Weerg staff: Feb 25, 2026

Polymers represent one of the most versatile families of materials in modern industry. Within this category, the fundamental distinction is between thermoplastic polymers and thermosetting polymers: two classes with profoundly different behaviour in relation to heat, processing and final use.
