What are the Benefits of Point of Care 3D Printing?

The main benefits of point of care 3D printing involve enhancing the number of options available for clinicians when working with patients. In particular, the growth of on-site 3D printing hubs and regulatory clearance for software and hardware combinations makes it easier for 3D anatomical models to be integrated into traditional workflows without significant delays. Physical models make it easier to visualize surgeries ahead of time, with prints capable of being used to simulate procedures before going into the operating room.

When dealing with complex surgical and diagnostic scenarios, 3D printed models offer an additional resource to explain and illustrate planning to colleagues and patients. As a complement to virtual models, physical models can be designed to accurately represent the touch and feel of anatomies, making it easier to reassure patients ahead of surgeries. In addition, models can be repurposed as hands-on teaching aids for trainee clinicians.

In terms of operational factors, point of care 3D printing can help to improve general problems for hospitals and other clinical settings, from reducing the risk of revision surgeries through personalized models, to increasing the choice of bioprinting options through different structures that are compatible with the human body. Entire patient workflows can therefore be made more customizable and scalable to a particular institution.

The uptake of 3D printing in these settings has been recognized at the regulatory level by the U.S. Food and Drug Administration, whereby devices and workflows can be factored into manufacturing and the development of new devices that incorporate printing, or that use it as part of validation workflows. Some more information on the current approach of FDA, and ongoing questions, can be found .

How Does Point of Care 3D Printing work?

Hospitals using point of care 3D printing may have an in-house hub with machines and technicians to produce their models or might outsource to a partner company that can turn around scans and models to specific deadlines. In both cases, the process typically begins with obtaining a 3D scan of the patient’s anatomy via methods such as MRI, X-ray CT, CT, or 3D ultrasound. The resulting image data can then be processed in software to segment, or isolate, regions of interest, and take measurements.

草榴社区 Simpleware software, for example, includes a number of segmentation tools to process 3D image data, as well as to prepare files for a 3D printer by adding connectors, logos, colors, and other features. Before printing, the 3D models may be segmented into multiple surface parts representing different parts of anatomy, pathologies, and medical devices, and exported as STL files to a 3D printer. At this stage, surfaces might also be portioned to help with disassembly and reassembly. 3D printers receiving the data can then complete the final steps, such as support structures, before creating the final model using different materials and finishing processes.

Where and When Does Point of Care 3D Printing Fit in the Product Portfolio?

Point of care 3D printing is established within 草榴社区 through Simpleware ScanIP Medical software, an FDA 510(k)-cleared and CE-marked product. The software has been validated with certain 3D printers to enable a complete workflow from 3D imaging to segmentation, measurements and landmarking, a combination of anatomical images with CAD models, and finally to export and printing. 草榴社区 has also to help widen awareness and uptake of 3D printing in healthcare settings.

Going Beyond Point of Care 3D Printing

While Point of Care 3D printing is a rapid and easily reproducible method for hospitals, additional options are also available for R&D by medical device manufacturers and those combining clinical practice with research. In this context, medical device manufactures use Simpleware software to test implant designs, export models for simulation of part performance, and to utilize AI-based automation tools to scale up analysis and production of 3D parts.
