How It Works
Zâmbet uses a custom-built AI pipeline to transform a single headshot into a personalized jewelry pendant.
​
Below are actual outputs of Zâmbets algorithm, displaying both digital and physical manufacturing outputs.
Input a headshot
Receive a custom pendant
1. Facial Feature Segmentation
The process begins with image segmentation, where the input headshot is broken down into distinct facial regions such as eyes, nose, lips, ears, and cheeks.
This segmentation model is trained using the CelebA-Mask-HQ dataset, which contains over 30,000 publicly available, high-quality headshots with detailed facial annotations.
2. Feature Aware 3D Construction
Once the face is segmented, each facial region is processed independently using a monocular depth estimation model (based on the open-source MiDaS architecture).
​
Analyzing features separately prevents visual ambiguity caused by strong color contrasts, for example between lips and teeth, and allows the system to treat different facial structures appropriately. Complex geometries like ears are analyzed differently than smoother surfaces such as cheeks, resulting in a more accurate three-dimensional profile.
​
Note how the iris appears significantly darker than its surroundings. The color contrast causes the algorithm to misinterpret the boundary between the iris and the whites of the eye, incorrectly projecting the iris toward the back of the head. This behavior highlights a flaw in the algorithm’s depth inference.
3. Assembly and Pendant Construction
The reconstructed 3D facial components are then stitched together into a unified three-dimensional headshot. This final model is refined, flattened into a pendant-ready relief, and prepared for fabrication as a wearable piece of jewelry.
The result is a highly personalized pendant that preserves the unique facial structure of the subject, created from a single photograph.

The prototype to the right is fabricated out of aluminum oxide. The same slurry based lithography techniques can be used to make the same parts out of any precious metal. A US quarter is placed next to the prototype for reference.

Our Story
I was in a severe car accident as a young child that resulted in the loss of my four front teeth and nearly fifteen years of dental work. After orthodontics, corrective jaw surgery, and implants, I finally achieved a full smile. The impact was immediate and profound. My confidence improved, and everyday acts like eating, speaking, and socializing became natural again.
That experience led me to LightForce Orthodontics. What I initially hoped would open the door to dental school instead introduced me to digital manufacturing and the power of mass customization.
Traditional manufacturing constrains output to identical geometry, producing the same part repeatedly. Additive manufacturing, despite its tradeoffs, removes that limitation. Digital manufacturing when combined with additive manufacturing, unlocks the ability to produce parts that are the same, but different.
The idea crystallized at the Formnext trade show in Frankfurt, where I encountered a lithography-based metal printing system capable of producing parts in precious metals like gold, platinum, and silver. While searching for a holiday gift for my mother, it clicked. The same mass-customization principles used at LightForce could be applied to jewelry, creating a pendant that captures a smile.
After teaching myself to build an AI pipeline and training an image segmentation model, I fabricated my first prototype. Zâmbet, the Romanian word for smile, was born.

What's Next
Zâmbet is actively refining its model to reliably generate high-quality outputs. Using qualitative evaluation, the current system produces acceptable pendants approximately 50% of the time. Fine facial features, such as open eyes, teeth, and ears, remain the most challenging to reproduce. The near-term objective is to achieve high-quality digital outputs in 98% of a 1,000-image sample. Reaching this milestone will enable a fundraising round to support launch preparation.
Preparing for launch will focus on three core areas:
-
Marketing
-
Brand development
-
Website design
-
Digital marketing
-
-
Customer Interface
-
Develop a customer portal allowing users to generate a digital file at no cost
-
-
Manufacturing
-
Establish a production partnership with a contract manufacturer
