Understanding AESUB Dice: A Must-Have Tool for Accurate 3D Scanning

Need to use reference markers for 3D scanning but can’t—or prefer not to—stick dots on the object? AESUB Dice offer the perfect alternative!

In this guide, we will cover the following topics:

What are AESUB Dice?

AESUB Dice are geometric objects with circular markers on their multi-sided faces. They are used when 3D scanning challenging objects that lack distinctive features.

Featureless objects—especially along edges and corners—as well as symmetrical parts pose significant challenges in 3D scanning, often leading to scanner tracking issues and reduced accuracy. AESUB Dice effectively address this issue by providing a reliable and precise reference tool for seamless scanning. By providing additional reference points, AESUB Dice help 3D scanners maintain tracking and also make it easier to align and stitch multiple scans into a complete 3D model.

These lightweight reference markers simplify 3D scanning of challenging objects by allowing you to place them directly on the part being scanned (available in magnetic and M4 thread versions). One of the big advantages is that AESUB Dice offer quicker setup with less preparation compared to applying individual reference markers. This reduces setup time and improves scanning efficiency—especially valuable when scanning parts on-site.

With 11 faces, the AESUB Dice feature coded targets on multiple sides, making it easier for the 3D scanner to detect them from various angles during the scanning process.

What this means:

• Less repositioning of the marker
• Better tracking, especially in 360° or complex object scans
• Reduced blind spots compared to flat or single-face targets

AESUB Dice are especially great for:

• Multiple angle views
• Low scan angles
• Perfect for corners

Each one has an offset bottom for minimized covered surface.

This video demonstrates how AESUB Dice excel at angular detection—even at 90 degrees—ensuring the 3D scanner maintains tracking.

Benefits of using AESUB Dice

Here are the top reasons for using AESUB Dice:

1. Reusability

   Unlike AESUB Dots—which are adhesive, single-use reference markers—AESUB Dice are reusable and can be used repeatedly without losing accuracy.

2. Less Time Spent on Preparation and Cleanup

   AESUB Dice don’t require sticking or peeling. Simply place them on the scan object or in the surrounding area. Save time on prep work before scanning and post-scanning clean up.

   

   

3. Superior Stability and Accuracy

   The rigid structure and high manufacturing precision of AESUB Dice ensure exceptionally stable and accurate reference geometry for aligning scans—especially useful in metrology-grade or high-precision work.

4. Ideal for Challenging Surfaces

   On curved or delicate surfaces where dots don’t stick well, AESUB Dice are a safer and more reliable option.

5. Flexibility in Using Them for Small to Large Objects

   Due to the size of AESUB Dice, it’s generally more convenient for larger objects. However, you can use AESUB Dice on smaller objects by placing a few around the scan target.

   When scanning an object on a table, placing a few AESUB Dice around the object can significantly improve your workflow and deliver more accurate results. You can even use them on small symmetrical objects like a coin.

6. Better for Complex Scan Setups

   In setups where multiple views or scan positions are needed, AESUB Dice maintain consistent reference geometry across all angles—something dots can struggle with if they shift or detach.

When do you use AESUB Dice instead of AESUB Dots?

The comparison chart below outlines the similarities and differences between these reference markers to help you choose the most suitable option for your needs. It’s not about one being better than the other, as each is designed to perform best in specific situations. Think of it like using different types of knives: a butter knife works well for spreading, while a paring knife is best suited for peeling fruit or making detailed cuts.

Comparison between AESUB Dots and AESUB Dice

	AESUB Dots	AESUB Dice
Type	Individual reference markers (stickers)	Multi-faced polyhedron reference markers (objects)
Form Factor	Flat, adhesive dots	Solid geometric object with 11 faces
Use Case	Scanning featureless objects Scanning objects with large, flat, or simple surfaces	Scanning featureless, more complex objects where markers can't be attached Scanning objects with multiple angle views, low scan angles, or corners Scanning objects with large, flat, or simple surfaces
Placement	Placed directly on the object or surface, or near the object
Reusability	Usually single-use	Reusable
Detection Method	2D pattern recognition	Coded 3D geometry with identifiable marker patterns
Cost Efficiency	Low-cost per use	Higher upfront cost, long-term reusable
Adhesive	Yes, uses adhesive backing	No sticking required. Available as magnetic or M4 thread. Also use putty for sticking if needed.
Ideal Surface Conditions	Flat surface, with room to apply markers	Delicate or curved surfaces
Portability	Highly portable (small and flat)	Portable but bulkier than dots
	AESUB Dots	AESUB Dice

When Do You Use AESUB Dots Instead of AESUB Dice?

AESUB Dots are a smart choice for short-term projects due to the cost when compared with AESUB Dice, which are reusable. When scanning flat or easily accessible surfaces, dots offer a simple yet effective way to ensure accuracy without adding bulk or complexity to the workflow.

Benefits of AESUB Dots:

• Higher Density of Markers: You can apply many dots in close proximity, providing dense referencing for intricate scanning tasks.
• Cost-Effective for Single Use: Dots are relatively inexpensive and ideal for one-time or short-term projects.
• Better for Flat or Matte Surfaces: When the surface allows for sticking markers, dots provide excellent accuracy.
• Lightweight and Low Profile: Being flat and small, they don’t interfere with the scanning process or object handling.

Key Technical Properties of AESUB Dice

Dealing with Multiple Scanning Challenges

What do you do when you're scanning a featureless object as well as a challenging surface—one that's reflective, transparent, or dark?

You can combine the use of AESUB Dice and AESUB Dots to solve both challenges at once.
