Welcome to our comprehensive guide on selecting the ideal 3D scanner for reverse engineering. Whether you’re dealing with mechanical objects or intricate designs, finding the right scanner is crucial for accurate CAD models and successful project outcomes.
Determine Your Use Case
Understanding your specific needs is the first step. Are you scanning small mechanical parts, large objects, or items with complex surfaces? Let’s explore the options:
3D Scanner Options
Einscan SP & Pro HD
The Einscan SP and its big brother, the Pro HD, are excellent choices for small objects. They offer high detail, accuracy, and resolution, making them ideal for reverse engineering. However, structured light scanners struggle with dark, reflective, or transparent surfaces.
Einscan H2
The Einscan H2 is great for body scanning, full-color scans, and even cars. While it handles black surfaces better than other structured light scanners, it still falters with reflective and transparent surfaces.
Einscan HX
Featuring blue lasers, the Einscan HX excels on black and reflective surfaces, providing high accuracy without needing scanning spray. This scanner is versatile and effective across various surfaces.
Freescan Trio
Laser scanners like the Freescan Trio require markers, adding extra steps but offering superior accuracy. It’s more suited for larger objects and includes a photogrammetry mode.
Freescan Combo
The Freescan Combo combines laser and infrared modes for markerless scanning of large objects with high precision. With an accuracy of 0.2 mm, it’s perfect for detailed mechanical parts and inspection tasks in machine shops.
Additional Tools and Techniques
Turntable / Marker Table
Using a marker table can simplify scanning by eliminating the need to place markers on the object itself. This is especially useful for reverse engineering tasks.
Disappearing Scanning Spray (AESUB)
Scanning spray helps with capturing data from reflective or transparent objects. AESUB spray evaporates after a few hours, leaving no residue, and is particularly useful for difficult surfaces.
Scanning Process and Results
After setting up your scanner and preparing your object, scan from multiple angles to ensure comprehensive data capture. Utilize tools like Geomagic Essentials for processing and converting your scan data into CAD models.
For example, scanning with the Freescan Combo and using AESUB spray can significantly enhance data quality, even on challenging surfaces.
Conclusion
Choosing the right 3D scanner depends on your specific needs and the nature of the objects you’re scanning. From the Einscan series to the Freescan options, there’s a solution for every application.
