Hospital Authority (HA) of Hong Kong is considered to be Immune material’s earliest recurring client, as well as granting the status of authorized supplier.

Since the workshop’s opening, HA has collectively commissioned hundreds of IMU+®  embedded products and IMU+® antimicrobial materials, where they play a vital role in enhancing infection control and protecting the patient’s, visitor’s, and staff’s hygienic safety.

Enhancing Queen Elizabeth Hospital Hygiene with IML’s IMU+ 3D-Printed Antiviral Technology

Background

Queen Elizabeth Hospital (QEH) is one of the largest hospitals under the joint management of the Hospital Authority (HA) in Hong Kong. Located in the southern Kowloon district, QEH boasts a capacity of over 1,900 beds and provides a comprehensive range of services for both inpatients and outpatients. As a major tertiary hospital, QEH plays a critical role in serving the region's healthcare needs.

Shortly after IML’s production workshop began operations in 2022, QEH partnered with IML to implement innovative solutions for infection control. The hospital commissioned the production of IML’s IMU+ 3D-printed (3DP) Antiviral Handle Covers, which were installed on ward doors, office doors, and trolleys throughout the facility. This initiative aimed to enhance hygiene measures in high-contact areas and improve the safety of patients, staff, and visitors.

The Challenge

In mid-2022, Hong Kong was grappling with the aftermath of the fifth wave of COVID-19—the city’s most contagious outbreak to date—peaking at 50,000 cases a day. As hospitals struggled to manage the surge in cases, the sixth wave emerged, leaving healthcare facilities overstretched and vulnerable to further outbreaks.

QEH, like many hospitals, faced an urgent need to strengthen infection control measures to prevent the spread of pathogens in high-contact areas. Antimicrobial products became critical for minimizing infection risks by actively reducing harmful pathogens on frequently touched surfaces. However, traditional coatings on surfaces often wear off quickly, diminishing their effectiveness over time. Hospitals needed durable, cost-effective solutions to improve hygiene protocols, create safer environments, and reduce the risk of cross-contamination for patients, healthcare workers, and visitors.

Our Solution

IML’s IMU+ technology provided a critical solution to QEH’s challenges. IMU+, an advanced antimicrobial agent, is capable of killing over 99% of surface-level pathogens within 20 minutes of exposure, including the COVID-19 virus. Using our in-house 3D printing (3DP) capabilities, IML produced custom-designed handle covers tailored to fit the hospital’s doors and trolleys. These products were developed to maximize hygienic safety while minimizing costs.
 

Unlike traditional filament (FDM) printing, IML employs liquid crystal display (LCD) printing, which allows for a smooth, non-porous surface finish that is both pleasant to the touch and easy to clean. This ensures that the handle covers not only deliver superior antimicrobial performance but also meet the aesthetic and functional requirements of hospital environments.
 

QEH proudly became the first hospital in Hong Kong to implement IML’s Anti-COVID-19 3DP products, marking a groundbreaking achievement in the adoption of advanced antimicrobial technologies in healthcare. Despite some initial curiosity about the product’s antiviral efficacy and appearance, QEH was thrilled with the outstanding results. Their positive experience not only validated the product's effectiveness but also inspired other HA-affiliated hospitals to explore IML’s innovative solutions.

The Benefits

The collaboration between QEH and IML successfully demonstrated the efficacy of IMU+ 3D-printed antimicrobial products in a high-demand healthcare setting. Key benefits include:

  • Enhanced Infection Control: The IMU+ handle covers actively reduced surface-level pathogens, protecting patients, staff, and visitors during critical times.

  • Cost-Effectiveness: The custom 3DP handle covers were designed to be durable and long-lasting, reducing the need for frequent replacements and lowering overall maintenance costs.

  • Improved Hygiene Protocols: The smooth, easy-to-clean surface of the LCD-printed products contributed to more efficient cleaning practices and supported the hospital’s infection control measures.

  • Proof of Concept: QEH’s adoption of IML’s products validated the practicality and effectiveness of IMU+ technology, encouraging other hospitals under the Hospital Authority to explore similar implementations.

Conclusion

Queen Elizabeth Hospital’s partnership with IML marked a significant step forward in the fight against hospital-acquired infections during the COVID-19 pandemic. By leveraging the advanced antimicrobial properties of IMU+ and the precision of 3D printing technology, QEH not only enhanced its infection control measures but also set a precedent for innovation in healthcare.

This successful collaboration underscores the potential of IML’s IMU+ technology to transform hygiene practices in healthcare settings, ensuring safer environments for patients, healthcare workers, and visitors alike. As more hospitals recognize the value of durable, cost-effective antimicrobial solutions, IML remains committed to supporting the healthcare industry with cutting-edge products tailored to their needs.
