The advent of 3D printing technology has revolutionised various fields, from manufacturing and healthcare to fashion and art. On a lovely sunny day, a real-life case of facial trauma led to the use of 3D printed face technology, a story we will explore in detail later.
One of the most intriguing and rapidly evolving applications is 3D printing faces. This technology offers groundbreaking possibilities, from creating realistic facial prosthetics to customising masks and even immortalising one’s visage in a lifelike sculpture.
By leveraging 3D printing, it is now possible to significantly enhance the visual aspects of facial prosthetics and reconstructions, improving realism and boosting patient confidence.
Let’s delve into the fascinating world of 3D printed faces and explore how this innovation is shaping the future, ensuring the best results in terms of print quality and efficiency.
For individuals who have suffered facial injuries or congenital deformities, 3D printed prosthetics provide a lifeline. These advanced solutions are especially valuable for patients with full-thickness burns and partial-thickness burns, which damage all layers of the skin and require complex reconstruction. 3D printed prosthetics are also used for those needing a large orbital prosthesis after severe eye socket injuries.
One such case is that of Dave Richards, also known as Mr Richards, a dedicated family man and cyclist. On a lovely sunny day, Dave and his two friends were cycling when a speeding drunk driver, who was over the drunk driving limit, struck them and then left the scene. While his two friends were thrown clear, Dave was trapped under the car, suffering severe injuries, including broken ribs, exhaust, and half his face. Dave was lucky to survive, but he endured all the pain of his injuries, both physically and emotionally, especially in the early days of his recovery. The drunk driver received a reduced sentence and was released early for good behaviour, which left Dave and his family feeling the impact of the justice system.
Dave underwent complex medical procedures, including free flap surgery—free flap taking tissue with blood arteries and veins, and tissue with blood arteries—from other parts of his body. This involved taking tissue and transplanting it to his face, with the flap completely covering the damaged area and the need to secure the flap completely. There was also a risk of infection spreading down the optic nerve. During his recovery, Dave wore a neck brace to help soften scar tissue and improve comfort, and his patient’s progress was closely monitored. Dave’s recovery has been remarkable; he continues to rebuild his confidence, has started indoor cycling as part of his rehabilitation, and 3D printed prosthetics have played a crucial role in restoring his appearance and function.
Traditional prosthetic methods can be time-consuming and may not achieve a perfect match. These methods relied on impressions from manual processes, such as wax impressions and moulds, which were less precise and often uncomfortable for patients. Wax impressions from manual processes were commonly used before the adoption of digital 3D scanning.
By using different materials, 3D printing allows for highly customised and accurate facial prosthetics, significantly improving the quality of life for patients. Surface scanning patients with advanced 3D imaging technology enables the creation of accurate models for prosthetic fittings and ongoing adjustments.
These prosthetics can be made to match skin tone, texture, and even fine details, providing a seamless appearance. 3D printed prosthetics can be designed to closely resemble the patient’s original facial features, including eye colour and skin, and the technology mimics his hair colour for a more natural appearance. For patients who have lost part of the side of their face due to trauma, 3D printing allows for precise reconstruction and improved appearance. 3D printing also enables the creation of a far more natural implant compared to traditional methods. These advancements help patients feel more confident in their appearance and social interactions.
3D printed prosthetics can also accommodate movement, improving comfort and daily function. Some patients may need to wear prosthetics or splints for long periods during recovery. Monitoring scars using advanced scanning is important to track healing and adjust prosthetics as needed, and it also helps track the patient’s progress over time using 3D scanning and printing technologies. The use of neck scar splints and neck braces, particularly custom-made or 3D printed ones, helps manage scar tissue, support healing, and improve comfort after facial injuries.
Treatments are used to soften scar tissue, reduce scar tension, and improve the appearance of the scar line. In some cases, follow-up procedures are needed to release tightened scar tissue after initial surgery, and further surgery may be required to optimise results and track the patient’s progress over time. Reconstructive prosthetics created with 3D printing technology offer improved realism and confidence for patients.
Surgeons use 3D printed models of patients’ faces to plan complex reconstructive surgeries. Senior reconstructive scientists, with expertise in surface scanning, 3D printing technologies, and prosthetic design, provide scientific and technical support throughout the treatment process, ensuring precise planning and execution of reconstructive surgeries. Amy Davey is recognised as a leading expert in the use of advanced 3D scanning, digital design, and printing technologies for facial reconstruction and prosthetics.
These models help in visualising the exact structure of bones and tissues, allowing for precise surgical planning. Creating a 3D model for surgical planning enhances the accuracy and effectiveness of the procedure.
Additionally, 3D printed faces are used in medical training, providing students with realistic models to practice on before performing actual surgeries. The file for 3D printing these models is crucial, as it ensures the accuracy and quality of the training aids.
Artists and designers are leveraging 3D printing to create custom masks and lifelike portraits. These masks can be used in theatre, cosplay, or as unique fashion accessories.
When exporting a 3D printable file, it is crucial to select the correct file format, such as 'export STL file', to ensure compatibility with the slicer app for 3D printing. Portraits made using 3D printing capture every detail of a person's face, offering a modern twist to traditional sculpture and art forms.
In the entertainment industry, 3D printed faces are making waves in virtual reality (VR) and gaming. By creating realistic avatars based on a person's face, developers can enhance the immersive experience of VR and games.
Slicer software, such as Ultimaker Cura, PrusaSlicer, Simplify3D, and FlashPrint, is used for preparing 3D models for printing. This technology also enables more accurate facial recognition and expression in digital environments, making characters more relatable and engaging.
For those looking to immortalise their appearance, 3D printed busts and miniatures are becoming popular. The final step in finishing these printed busts and miniatures involves tasks such as removing support structures, sanding, polishing, painting, or coating to improve their appearance and functionality.
These personal keepsakes make for unique gifts and can be passed down through generations, preserving family heritage in a tangible form.
The future of 3D printed faces holds immense potential. Future advancements will open up a whole range of possibilities for facial reconstruction, including the ability to produce materials that closely match natural tissue. Post-processing will play a crucial role in future advancements, improving the appearance and functionality of printed objects. As technology advances, we can expect even greater accuracy, affordability, and accessibility.
Selecting the right printer will be essential for achieving realistic textures and colours. Innovations in materials, such as the use of advanced plastic resins, will lead to more realistic and durable prosthetics, further enhancing the applications in medical, artistic, and cultural fields. Future prosthetics will involve advanced plastic resins that are safe for long-term skin contact and closely resemble natural bone and tissue, enabling more natural and comfortable implants.
Additionally, the integration of artificial intelligence and machine learning will enable more sophisticated modelling and customisation, pushing the boundaries of what’s possible.
3D printed faces are more than just a technological novelty; they represent a convergence of art, science, and innovation.
Whether it's transforming medical procedures, revolutionising the arts, or preserving our heritage, the applications of 3D printed faces are vast and varied. As we continue to explore and refine this technology, the possibilities are limited only by our imagination.
