📸 3D Scanning – Digital Revolution in Reality Capture

In today’s world of precision, customization, and rapid prototyping, 3D scanning has emerged as one of the most powerful tools in modern engineering and design. From medicine to manufacturing, art to archaeology – 3D scanning helps us digitize the real world with amazing accuracy. 🌐✨

In this article, we’ll explore:

🧠 What 3D scanning is and how it works
🔍 The main types of 3D scanners
📦 Where and why it’s used
🎯 How ElWood 3D integrates scanning into their process

🔍 What Is 3D Scanning?

3D scanning is a process that captures the geometry and appearance of physical objects and converts them into precise digital models. Using various techniques, it creates a point cloud or a mesh, which can be used in 3D modeling, analysis, or direct 3D printing. 🖨️📐

The result? A digital twin of a real-world object, ready to be analyzed, modified, or printed.

⚙️ Types of 3D Scanners

There are multiple 3D scanning technologies on the market, each suited to specific needs and environments:

🔦 Laser scanners – extremely accurate, often used in industrial applications
💡 Structured light scanners – fast and contactless, ideal for body scanning and design
📷 Photogrammetry – uses multiple photos taken from various angles
📱 Mobile scanning (LiDAR) – built into modern smartphones and tablets

🚀 How ElWood 3D Uses 3D Scanning

At ElWood 3D, 3D scanning is deeply integrated into our workflow. Whether a client sends us a physical object or just wants something recreated — we scan, model, optimize, and print. 🎯

Here’s how we use it:

📦 To recreate missing or broken components
🔁 To modify existing items based on new needs
🧩 To build clean STL files from scans for precise 3D printing

After scanning, our team processes the model using the latest tools and slices it for high-quality printing using PLA, PETG, TPU and even metallic composites. 👉 Related: 3D Printing with Metal
