The Role of 3D Printing Services in Medical Innovation

3D printing, also known as additive manufacturing, allows healthcare providers to create custom medical equipment. It can be used to manufacture replacement parts and make made-to-measure prosthetics.

In addition, the technology is being used for creating models of human anatomy to help surgeons prepare for complex procedures. One study showed that using 3D-printed anatomic models decreased surgical time by 62 minutes.

Cost Effectiveness

3D printing technology allows medical organizations to create spare parts on demand, cutting down inventory costs. This means that there is no need to keep a stock of items that are rarely used or require constant replacement. Instead, the spare parts can be printed on request, reducing the number of storage and shipping expenses that would otherwise need to be incurred.

The cost of a 3D print depends on the complexity of the model and the material used. Complex models with many overhangs or a high percentage of infill require longer printing time and consume more material, driving up the overall cost. Manufacturers can improve the cost-effectiveness of their prints by optimizing their designs and choosing the appropriate build volume.

Additionally, the use of 3D-printed guides reduces operating room time, saving money on equipment and labor. The breakeven point for using 3D-printed anatomic models or surgical guides is calculated by dividing annual operational costs by cost savings per case, using previously published data on operating room time savings with maxillofacial and orthopedic focuses.

Beyond prototyping, 3D printing can be used for end-use production parts as well. Streamlined manufacturing processes can result in lower part counts, simplified geometries, and reduced weight, all of which reduce machining and assembly costs. For example, GE has developed walnut-sized jet fuel nozzles that can be printed in multiple parts to save on assembly and weight while maximizing performance.

Customization

Custom 3D printing is a revolutionary technology that allows for mass customization by making bespoke products more accessible. 3D printing can produce a wide range of shapes and structures that are not possible with traditional manufacturing methods, and it can be used to create a range of products, including prosthetics, orthotics, and dental aligners. It can also be used to create prototypes and test models before committing to an expensive investment, ensuring that the final product will meet all necessary requirements.

The process of 3D printing is unique from other traditional manufacturing techniques because it builds up objects layer by layer based on a digital design. This makes it possible to create complex shapes and intricate geometry that would be impossible with other technologies. In addition, it reduces assembly requirements and streamlines logistics by eliminating the need for assembly tools or manual handling. Furthermore, it is energy-efficient, saving on electricity costs during the printing process and throughout the product’s operating life.

Choosing the right 3D printing service provider is vital to ensure that the quality and precision of the prints are up to par. Evaluate a potential provider’s experience and expertise, and ask for samples to evaluate the level of detail and accuracy achieved in their prints. It is also important to consider the pricing structure and turnaround time, as this will influence the cost of the finished print.

Safety

With 3D printing technology, companies can create prototypes that are highly accurate and allow for quick testing of tolerances before moving to production. This allows engineers to optimize for performance, resulting in significant cost savings. 3D printers can also be used to create custom-fit prosthetics for patients, helping to eliminate the need for costly, time-consuming adjustments. This innovative technology has been widely embraced across numerous industries, from healthcare to construction and automotive. In fact, Habitat for Humanity recently partnered with PERI 3D Construction to print the first home using this method, reimagining what affordable housing may look like in the future.

However, the use of this technology comes with a number of health and safety concerns that need to be addressed in order to safeguard the well-being of users. The main issues involve the emission of fumes from 3D printers, which can produce harmful concentrations of ultrafine particles and chemical vapors.

Depending on the materials and printing processes used, health hazards can vary from skin and respiratory irritation to the potential toxicity of the finished product. For example, the popular filaments acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) emit toxic fumes when they are heated. Additionally, the metal printing process known as Directed Energy Deposition produces ultrafine particles and volatile organic compounds (VOCs) when the powdered metal is exposed to a heat source.

Environmental Impact of 3D Printing

3D printing has a positive impact on the environment because it reduces material waste and energy use. Furthermore, it allows for a more streamlined supply chain and reduces transportation costs and carbon emissions. The technology also encourages innovation in the healthcare industry, allowing for the production of customized medical devices and prosthetics that are tailored to each patient’s unique anatomy.

For example, surgeons can use 3D-printed models of the patient’s anatomy to identify possible risks and complications before performing surgery. This improves surgical outcomes and reduces operating time and patient recovery times. The customization capabilities of 3D printing also enable doctors to create more effective treatment plans for patients with complex conditions.

Another benefit of 3D printing is that it allows for on-demand manufacturing, reducing the need to maintain large inventories of medical equipment. This is particularly beneficial for hospitals with limited space. Additionally, it allows for the production of medical devices and implants in remote locations, increasing access to healthcare services in underserved areas. Although 3D printing has a positive impact on health care and the environment, it must be carefully used in conjunction with other technologies to ensure safety. While this new technology has the potential to reduce the environmental impact of traditional manufacturing, it must be legitimized before it can be widely adopted.
