Case Study: Kunming Medical University achieves faster, more effective facial scar treatment with Stratasys 3D-printed masks

Hong Kong Polytech University doctor 3D prints face masks to treat burn scars

Kunming Medical University’s Second Affiliated Hospital, led by Dr. Wei Yating, faced the challenge of treating pediatric facial hypertrophic scars from burns, where traditional plaster-molded pressure masks are time-consuming, painful, opaque and often poorly fitted. To find a less invasive, more precise option, the team turned to Stratasys technology, using the Objet30 Prime printer and biocompatible MED610 material to explore 3D‑printed transparent therapeutic face masks.

Using non‑contact facial scanning, CAD customization and Stratasys’ Objet30 Prime, the team produced fitted masks in one day (versus 5–7 days for plaster molds), with controlled modifications to within 5 mm and digitally smoothed designs for comfort. The Stratasys-enabled solution delivered more even pressure distribution, greater patient comfort and confidence, and follow-ups at one and three months showed a significant decrease in average scar thickness and hardness; the research also produced two academic publications.
