In the dynamic field of healthcare simulation, 3D printer technology offers many possibilities for the enhancement of educational experiences. However, simulation centers must carefully consider the pros and cons before such a significant investment is made. This article by Rémy Roe, Ph.D and Simulation Technology Specialist at the Stanford University School of Medicine’s Center for Immersive and Simulation-based Learning (CISL), will explore the advantages and challenges of the incorporation of 3D printers into healthcare simulation programs, and focus on four key areas: initial costs and long-term cost benefit, space requirements, educational benefits, and technical considerations.
Initial Costs and Long-Term Cost Benefit
The upfront investment for 3D printer equipment can be substantial for healthcare simulation centers. High-quality 3D printers suitable for medical applications often range from $3,000 to $50,000 or more, with cost dependent on the model and capabilities. Additional costs may include materials, software licenses, and staff education. However, the long-term financial benefits can offset these initial expenses. 3D printers allow centers to produce custom task trainers, anatomical models, and simulation props in-house. This capability can lead to significant cost benefits over time, as centers reduce their reliance on expensive, pre-made commercial products.
For example, a clinical simulation center might spend $5,000 on a 3D printer and materials but save $15,000 annually when they print their own task trainers and anatomical models. Over a five-year period, this could result in a net of $70,000 saved, a strong return on investment. Moreover, 3D printers enable a center to rapidly prototype custom healthcare simulation tools. This flexibility allows centers to create unique, scenario-specific props that might otherwise be unavailable or prohibitively expensive to purchase.
Space Requirements and Infrastructure
3D printers require dedicated space within a clinical simulation center. A mid-range 3D printer typically needs an area of about 2 feet by 2 feet, plus additional space for material storage and equipment to post-process. Centers should also consider ventilation requirements, as some 3D printer materials can produce fumes throughout the print process. Infrastructure needs include a stable power supply, network connectivity for file transfer, and potentially specialized workstations for 3D modeling and print preparation. While these requirements may not be an encumbrance, they do necessitate careful consideration and a potential need to modify infrastructure.
However, there should be acknowledgement that a 3D printer can save space in the long run. Through the on-demand production of healthcare simulation tools, centers can reduce their inventory of pre-made products, and give back valuable storage space.
Educational Benefits and Versatility
The educational advantages of 3D printers in healthcare simulation are numerous. This technology allows for the creation of highly accurate anatomical models, which can enhance learners’ comprehension of complex structures and variations. Custom task trainers can also be designed to focus on specific skills or procedures and provide targeted practice opportunities. 3D printers also enable the development of patient-specific models based on actual medical imaging data. This capability allows for personalized clinical simulation scenarios and prepares healthcare professionals for unique cases they might encounter in clinical practice.
Another bonus of 3D printers is their ability to enable the creation of rare pathology models or complex anatomical variations that are difficult to source commercially. This expanded access to diverse educational materials enhances the breadth and depth of healthcare education, which means learners can encounter a wider range of medical scenarios in a controlled environment.

The versatility of 3D printers extends to multiple disciplines within healthcare. From the creation of dental models for orthodontic education to the production of custom prosthetics for rehabilitation clinical simulations, the applications are diverse and continue to expand. Furthermore, learner involvement in the 3D design and print process can foster creativity and the ability to problem-solve. This hands-on experience with emergent technology can be valuable for future healthcare professionals.
Technical Considerations and Challenges
While 3D printers offer many benefits, they also present technical challenges. Operation and maintenance of 3D printers requires specialized knowledge and skills. Healthcare simulation centers must invest in staff education or hire personnel with relevant expertise. The experience curve for 3D model software can be steep, and the creation of accurate medical models often requires advanced design skills. Centers may need to allocate resources for continued staff development or outsource some design work.
Print quality and material properties are another crucial consideration for medical simulations. To achieve the right balance of realism, durability, and cost-effectiveness can be a challenge that requires experimentation with different materials and print techniques. Additionally, 3D printers are not instantaneous machines. Complex models can take hours or even days to print, which requires a careful plan and schedule that meets clinical simulation needs.
3D Printers are an Investment for Simulation Centers
This article by Rémy Roe, Ph.D. and Simulation Technology Specialist, has discussed the pros and cons of healthcare simulation centers investment in, and subsequent use of, 3D printer technology. The decision to incorporate 3D printers into a clinical simulation program requires careful consideration of financial, spatial, educational, and technical factors.
While the initial investment can be substantial, the potential for long-term cost benefit and enhanced educational experiences makes 3D printers an attractive option for many healthcare simulation centers. The ability to create custom, highly accurate models and task trainers can significantly enrich educational environments and prepare healthcare professionals for a wider range of clinical scenarios. However, centers must also be prepared to address the challenges that come with the implementation of this technology, like space requirements, staff education, and continued technical support. The success of a 3D printer program often depends on dedicated personnel who can navigate the complexities of the 3D design and print process.
As 3D printer technology continues to advance, the applications in healthcare simulation will likely expand. Future developments may include more realistic multi-material printers, faster production times, and integration with other technologies, like augmented reality (AR). For simulation centers, a thorough assessment of current needs, future goals, and available resources is crucial. Pilot programs or partnerships with other institutions can provide valuable insights before commitment to full-scale implementation.
Ultimately, when thoughtfully implemented, 3D printers have the potential to revolutionize healthcare simulation and offer unprecedented levels of customization and realism. As the technology matures and becomes more accessible, 3D printers may become an essential tool for clinical simulation centers committed to the provision of the best medical education available.
