Case Study: Vowsmith achieves scalable, high‑detail mass personalization of wedding rings with 3D Systems ProJet MJP Series

3D Printing Helps Jewelry Start-Up Ride the Mass Customization Wave

Vowsmith, founded in 2014 by industrial designer Charles-Olivier Roy, set out to deliver premium, personalized wedding rings—each engraved with a partner’s fingerprint—while solving the challenge of making true mass customization scalable and affordable. The company needed a production method that preserved fine detail for casting, eliminated common casting faults, and could be automated from online ordering through to manufacture.

Vowsmith implemented an automated online customizer that converts customer choices and uploaded fingerprint images into high‑resolution STL files and prints them on a 3D Systems ProJet MJP Series real‑wax printer using VisiJet M3 Prowax. The result is crisp, cast‑ready models with easy post‑processing, high yield and energy savings; current throughput is 35–40 rings per print run with 3–4 runs per day (theoretical annual capacity ~50,000), a target 4–5k rings in the coming year, and a roadmap to 72‑hour order turnaround and global, inventory‑free scaling.
