Casting quality depends heavily on understanding the internal porosity of metal parts. Hidden voids and shrinkage pores can compromise integrity, lead to early failures, and increase costs - especially in safety-critical applications. While traditional thresholding methods like Otsu segmentation have proven effective for fast evaluations, they sometimes miss fine or low-contrast defects. To overcome these challenges, Dragonfly 3D World introduces AI-driven segmentation tools that take porosity analysis to the next level.

Computed tomography (CT) has evolved into a critical tool for non-destructive testing, yet its true value depends on the software used to visualize, segment, and analyze the data. This article breaks down the core technical requirements of modern CT software and explains how Dragonfly 3D World addresses each one with precision, speed, and real-world usability. From high-resolution CT visualization and AI-powered segmentation to sub-voxel surface extraction, GPU-accelerated processing, and automated inspection workflows, the article shows why 3D World has become a trusted platform across manufacturing, materials science, electronics, research imaging, and more.

Understanding the internal skeletal anatomy of fossilized organisms has long been a challenge in paleontology. The braincase, often concealed beneath layers of dermal bone, is rarely visible without damaging the specimen. Traditional mechanical preparation cannot expose delicate internal structures without loss of information.

Researchers have now overcome this challenge by using high-resolution micro-computed tomography (µ-CT) and advanced visualization tools in Dragonfly 3D World to study the braincase of Lepidotes, a bony fish that lived approximately 180 million years ago in ancient European seas.

Ancient pottery is like a time machine to the past – pottery relics give us insights into the cultures of the past. Most often, shards or fragments are found, rather than complete objects. Sometimes, nearly complete objects are found but are fragile and contain many cracks. But what exactly can X-ray CT reveal about an ancient vase? Let’s take a look.

The Megalodon is an extinct species of giant shark that lived millions of years ago, roaming the oceans in search of its next meal. It is said to be one of the most fearsome predators in earth’s history. Its huge jaws contained 276 large and sharp teeth growing up to 7 inches long, arranged in multiple rows. Today, many fossilized Megalodon teeth are still found and are often sold as collector’s items. But what can X-ray tomography tell us about an ancient Megalodon tooth? Let’s take a look.
