Breezm CEO Park Hyung-jin Presents 3D-Printed Eyewear Case Study at Harvard Business School

Breezm co-CEO Park Hyung-jin presented the company's business model at Harvard Business School (HBS) on May 4, 2026, as part of Professor Juan Alcacer's Owner/President Management (OPM) 'Strategy to Win' program. The presentation was based on the HBS case study 'Breezm: Innovative 3D Printed Eyewear (A),' which Alcacer authored and adopted as official course material. Park was joined by co-CEO Sung Woo-seok and US business development director Kim Si-hyun, who provided real-time feedback during discussions with global executives on market entry and localization strategies. The session focused on Breezm's personalized manufacturing system, which combines 3D printing with facial data analysis to address the standardized production and inventory challenges of the traditional eyewear industry.

This event places Breezm within a narrow but significant pattern: a Korean consumer-electronics vertical player using polymer vat photopolymerization (VPP) or material jetting to achieve product-market fit in a high-margin, mass-customization segment. The eyewear industry is a natural AM beachhead because it tolerates per-unit costs above injection molding while demanding geometric complexity and personalization that conventional manufacturing cannot economically deliver. Breezm's mobile-app facial scanning, virtual try-on, and data-driven design pipeline represent a complete digital thread from consumer to production, which is the same structural advantage that Align Technology exploited with Invisalign. The HBS case study adoption is a reputational signal, not a commercial milestone, but it does validate that Breezm's operational model is coherent enough to withstand academic scrutiny from strategy faculty.

The practical takeaway is that Breezm now faces the same scaling challenge as every mass-customization AM company: maintaining unit economics while moving from hundreds to tens of thousands of unique frames per month. The company's next credible signal will be production volume disclosures or a confirmed partnership with a major optical retailer in a developed market. For AM industry observers, the case study is a reminder that the most durable AM business models are often invisible to the hardware-centric press, quietly solving inventory risk in verticals where personalization is a feature, not a gimmick.
