How to Select the Right Resolution for Different Scanning Scenarios

Choosing the Right Resolution for Your Scanning Needs

EinScan series scanners offer a wide range of resolution settings — from as fine as 0.16mm to as broad as 3mm. With so many options, picking the right resolution for your specific scanning project can often be confusing. This guide will walk you through key points and recommendations to help you make the best choice.


What Does "Resolution" Mean in 3D Scanning?

Resolution, also referred to as “Point Distance,” is the smallest measurable distance between two points on a scanned model.

  • Higher resolution = more detail, closer representation to the real object.

  • Lower resolution = less detail, but faster scans and smaller file sizes.

Understanding Resolution Ranges and When to Use Them

1. High Resolution (0.16mm–0.24mm)

This is the scanner’s finest setting — offering maximum detail and accuracy. It’s ideal for small objects or items with intricate features, like jewelry or miniatures.

  • Pros: Excellent detail and realism

  • Cons: Slower scanning speed, longer processing time, large file size

  • Best For: Small artifacts, precision models, or anything requiring detailed restoration

Tip: Great for when detail matters most and the object is not too large.

2. Medium-High Resolution (0.3mm–0.5mm)

This range offers a balance between fine detail and manageable data size. It's often used in engineering and mechanical design where accuracy is important, but efficiency is also a priority.

  • Pros: Good detail with reasonable processing time

  • Best For: Reverse engineering, mechanical parts, functional prototypes

Tip: Ideal when you need both precision and workflow speed.

3. Medium Resolution (0.5mm–1.5mm)

This range is the most versatile and commonly used. It provides a good balance for everyday scanning tasks, offering decent detail without overwhelming processing requirements.

  • Pros: Balanced speed and quality

  • Best For: Furniture, household items, general use cases

Tip: Your go-to for most day-to-day scanning tasks.

4. Medium-Low Resolution (1mm–1.5mm)

This setting is optimized for scanning larger, non-rigid objects like the human body. It allows for quicker scanning and faster processing, which is crucial when scanning subjects that can’t remain still for long.

  • Pros: Fast scan speed, lower processing time

  • Best For: Human figures, biological models, educational use

Tip: Common in healthcare and academic settings where speed is essential.

5. Low Resolution (2mm and above)

This setting is designed for scanning large-scale items. While it doesn’t capture fine details, it excels in speed and efficiency, especially when dealing with big objects like vehicles or structures.

  • Pros: Extremely fast scans, small file sizes

  • Cons: Lower detail capture

  • Best For: Cars, boats, or any large object where detail isn’t the main focus.

Tip: Use this when speed matters more than detail — especially with large surfaces.

Final Thoughts

The resolution you choose should depend on both your object size and the level of detail required. While this guide gives general recommendations, your specific needs may vary. Evaluate your project's goals and choose a setting that gives you the best balance of accuracy, efficiency, and usability.
