Enhancing your 3D Printing Workflow with 3D Scanning

February 03, 2025

3D printing and 3D scanning are complementary technologies. 3D scanning transforms physical objects and the real world into digital models. On the other hand, 3D printing converts digital models into physical objects using a wide range of materials such as PLA, carbon fiber, metal, or even wood fibers.

Continue reading to learn how 3D scanning can enhance your 3D printing workflow and which 3D scanners we recommend for hobby and professional 3D scanning.

How does 3D scanning work?

While advancements in other industries may seem complex, the operation of 3D scanning technology is surprisingly straightforward. It functions by projecting structured light onto an object, which is then captured by cameras to produce an image of the object with the projected light pattern. By analyzing the distortions of this structured light on the object's surface, the scanner calculates the 3D coordinates of each point. These points are then combined to generate a digitized 3D model.

The synergy between 3D printing and 3D scanning

In most use cases, 3D scanners capture an object’s geometry, intricate details, and physical dimensions and store it in a computer as a 3D model. This 3D model can then be adjusted, based on a project’s specifications, dimensions altered, additional details added, or simply replicated, and printed using a 3D printer. Together they create a seamless feedback loop between the physical and digital worlds.

This combination makes it particularly useful for digital archiving (storing an object's original details), reverse engineering (recreating objects without digital files), or prototyping (adjusting the details of scanned objects using the digital model).

Why integrate 3D scanning into your workflow?

  • High accuracy and precision: 3D scanning captures an object’s details at the micron level, leaving no room for design errors, especially when designing models from scratch with CAD. 3D scanners have an accuracy ranging from 0.01 to 0.1mm, enabling them to capture hidden features and the finest details. While the accuracy of each 3D scanner is different and depends on the calibration and the technology used, the point cloud data can create a precise model for redesign or analysis, resulting in highly detailed prints.

  • Rapid prototyping and design iterations: With 3D scanning, manufacturers can capture the details of an object or part, digitize it, 3D print it, and analyze for defects faster than in traditional manufacturing. This allows for faster iteration and speeds up the design and production process. With rapid prototyping, manufacturers can save the cost of expensive tooling, especially in the early design stages, since iterations can be done directly on the digital model before 3D printing.

  • Reverse engineering: 3D scanning makes it easy to recreate or reference objects without access to the original CAD design files. This can include creating replacements for damaged parts or converting an existing object into a 3D model to replicate the design. This is especially useful for legacy parts, discontinued components, or historical artifacts.

  • Customization: 3D scanning makes it easy to tailor designs for specific applications, such as prosthetics, custom insoles, custom-fit tools, or personalized consumer products like custom car parts or wheels. Once the object is scanned using a 3D scanner, the model can be adjusted based on the new requirements before 3D printing.

Get Started with Einstar Vega and Einscan Libre

Whether you’re new to 3D scanning and need a hobby scanner to start with, or you’re into more professional applications, you’ll find the scanner for your needs at Shop3D. For hobbyist-level scanning, we recommend the Einstar Vega, and the Einscan Libre for professional use. 

Einstar Vega

The Vega is an all-in-one 3D scanner. Designed for versatility and precision, it combines two scanning technologies; MEMS Projection for highly detailed close-up scanning, with a working distance of 120~250mm, and VCSEL Projection for long-range scanning or outdoor 3D scanning, with a working distance of 350 ~ 1500mm. It comes with built-in computing and wireless solutions, and is easy to use and budget-friendly, making it ideal for hobbyists.

Einscan Libre

The EinScan Libre, on the other hand, is a fully wireless, standalone 3D scanner with a built-in screen and NVIDIA processor, offering a seamless and efficient scanning experience. It features laser and infrared light for adaptability across various materials and excels at capturing detailed textures. Its Laser HD mode enhances accuracy by supporting texture alignment, making it ideal for scanning complex surfaces. Notably, it is the first standalone 3D scanner to support texture alignment, ensuring high precision and ease of use. Its advanced features make it ideal for professionals looking for high accuracy, a powerful processor, and versatility in a 3D scanner.

Some of the overall benefits of both scanners are:

  • Wireless Scanning with Touch Interface: The Vega and Libre, featuring a 6.4” and 5.5” display respectively, enable built-in computing with their touchscreen displays for wireless scanning.

  • No need to tether to a laptop or computer: Most scanners require connecting to a laptop or computer while scanning. However, the Einstar Vega and Einscan Libre eliminate this need. With their truly wireless technology, you can scan on the go, wherever you need to go.

  • On-Site Scanning: Whether you need to scan outside your station or outdoors, you can simply pack your scanner and be on your way. Both scanners are lightweight and don’t require a cumbersome setup making it ideal for scanning on-site when necessary.

  • Easy to Use: While equipped with the latest scanning technologies, the Vega and Libre are intuitive and have an easy-to-use interface. You can learn to use them and start scanning in less than 30 minutes of unboxing.
