COVID-PPE

Community engagement and impact

In March 2020, at the start of the global COVID-19 pandemic, the UK’s supply chain for medical grade PPE collapsed under unprecedented demand and a workforce that could be sent into quarantine at a moment’s notice. As a result frontline clinical staff in some of the UK’s busiest hospitals were left to care for patients without adequate protective equipment. To respond to this, a coalition of experts in medicine and surgery, medical devices, product design and digital manufacturing was formed between Queen Mary University of London and the Royal London Dental Hospital to design safe, effective and reusable PPE (Personal Protective Equipment) that could be manufactured quickly to meet the urgent demands of London’s hospitals and medical and dental surgeries.

Outcomes

This project resulted in the manufacture of over 3,000 3D printed face visors, and a further 20,000 injection moulded visors which were distributed to hospitals, schools and community medical practices within days of the nationwide PPE shortage. These were also the second 3D printed face visors to gain regulatory apporoval (CE mark) in the UK, and the first to be specifically designed for high-risk aerosol generating dental procedures. The accompanying paper, “Innovation in the time of SARS-CoV-2: A collaborative journey between NHS clinicians, engineers, academics and industry” was published in the Journal of the Royal College of Surgeons of Edinburgh and goes into more detail about the manufacturing and logistical steps required to design and distribute a product, from scratch, within a matter of days.

High efficiency manufacturing of prosthetic sockets

Research Aims

  • Identify and develop advanced 3D printer designs to significantly increase the speed at which a viable, lower limb prosthetic socket can be manufactured.

  • Explore mateirals and manufacturing strategies to enhance the strength of 3D printed prosthetic sockets to a point where they can reliably pass ISO10328 testing.

  • Develop a logistical model sof distributed manufacturing of custom fitted prosthetic sockets in LMICs.

The Challenge

Millions of people worldwide, primarily in low and middle-income countries (LMICs), live with limb loss. Traditional prosthetic socket manufacturing is time-consuming, labor-intensive, and requires specialized skills. This creates a significant gap between the need for prosthetics and the availability of affordable, accessible solutions. While 3D printing offers potential, existing challenges such as slow print times and insufficient mechanical strength hinder its widespread adoption in LMICs.

The Solution

The POLAR 3D printer addresses these challenges by offering a rapid, cost-effective, and customizable solution for producing prosthetic sockets. Our innovative polar kinematics design significantly reduces print time compared to traditional Cartesian printers. By employing dual print heads and advanced materials, we aim to achieve the required mechanical strength while maintaining high production speed [1].

CAD render of the prototype POLAR 3D printer

Our Approach

We have developed a prototype polar 3D printer optimized for socket production. Key features include:

  • Polar kinematics: Enables faster circular motion, ideal for cylindrical socket shapes.
  • Dual print heads: Increase material deposition rate and allow for composite materials.
  • Advanced materials: Support for high-performance materials like PEEK and nylon to enhance strength.
  • Custom slicing software: Optimizes toolpaths for the polar printer, ensuring precise and efficient production.

Impact

Initial simulations demonstrate a dramatic reduction in print time compared to existing 3D printers. We are currently refining our prototype and conducting rigorous testing to evaluate print times, mechanical strength, and overall performance. Successful development of the POLAR 3D printer has the potential to revolutionize prosthetic care in LMICs by providing a scalable, affordable, and efficient solution for producing personalized prosthetic sockets.
