3D Printing in Healthcare Settings: Overview and Best Practices

Introduction

3D printers are revolutionary tools that bring digital models or scans into the physical realm. While the technology has been available for several years, it has become more affordable, accessible, and applicable across various industries, including healthcare settings such as local libraries, schools, and individuals owning 3D printers for as little as a few hundred dollars. In the healthcare context, 3D printers have limitless potential, serving as not just a "toy factory" but also as a resource for adaptive and medical education equipment, personalized keepsakes from bereavement experiences, and much more.

3D Printing Process

The typical steps involved in 3D printing, from start to finish, include the creation of a 3D model, conversion into sliceable code, the printing process, and post-processing. Each step presents various options and a learning curve, making decisions about the printer, software program, and 3D model crucial. This complexity makes 3D printing an ideal tool for Game Techs, offering flexibility and bandwidth that other hospital programs may lack to fully utilize this technology.

3D Model Creation

A 3D model is a digital representation of a three-dimensional object, surface, or scene created using specialized computer software, primarily computer-aided design (CAD). These models are essential in 3D printing, providing the digital instructions necessary for the printer to create a physical object.

Best Practices

FDM vs SLA in Healthcare Settings

In non-clinical pediatric healthcare settings, two suitable 3D printing technologies stand out: Fused Deposition Modeling (FDM) and Stereolithography (SLA).

FDM: This widely used process involves extruding thermoplastic filaments through a heated nozzle, building up the physical model layer by layer. FDM is popular for its simplicity, low cost, and versatility. It is suitable for the non-clinical healthcare setting due to its simplified workflow and minimal post-processing needs.
SLA: Utilizing a UV layer to cure a liquid resin layer by layer, SLA offers more detailed and complex geometries with finer features and smoother surfaces. However, it requires a more in-depth and time-consuming post-processing procedure, involving potentially harmful liquid solutions.

While FDM is a good initial fit for non-clinical healthcare settings, program-specific needs and accommodations may influence the choice of 3D printing technology.

Models/Scans as PHI

Considerations related to Protected Health Information (PHI) are crucial in 3D printing. General rules of thumb include:

3D Scans

Concerns arise from photographing and converting 2D images into 3D renders.
Identifiable features, whether facial scans or fingerprints, may fall under PHI/HIPAA concerns.

Printing Patient Data

When printing personalized data/models (e.g., patient scans, bereavement/legacy items), consider who may see the end product, especially when displayed to patients, families, and guests.

Storage of Patient Data

Ensure data storage adheres to hospital guidelines and rules, with metadata anonymized to protect patient information.
Be cautious if using cloud storage solutions, considering the risk of data leaks and the need for security measures.

Consent forms are recommended to ensure compliance with hospital procedures and standards regarding PHI and HIPAA. For more information on HIPAA cloud-computing and general HIPAA security guidance

While many hospitals have various operating procedures and standards, consent forms are always a safe step in ensuring and protecting staff and the hospital in a similar capacity as to when photography and videography is used.

Recommended Uses

-=== FDM vs SLS in Healthcare Setting ===
+== 3D Printing Process ==
-There are currently two major commercial types of 3D printing fused deposition modeling (FDM) and stereolithography (SLA). FDM is the most widley used and works by extruding thermoplastic filaments, through a heated nozzle and applying the plastic layer by layer to build a models. SLA uses a laser to cure liquid resin into hardened plastic creating detailed and smooth finished results. While SLA printers can create smaller and more detialsed prints, FDM is likely the best fit to use in the healthcare setting. The main reason for this is the the printing process and uses of resin, requires proper ventilation and often the use of a respirator when working with the materials.  Most spaces in a hospital do not allow for open windows or ventilation options that would make this process safe, making SLA a poor choice for this setting. If your program is located offsite, or has access to a workshop space, you may be able to make safety accommodations.

-==Slicers==
+*[https://www.printables.com/@LurieChildren_642788/models Models created at Ann and Robert H Lurie Children's Hospital of Chicago]
-Slicers are programs that take 3D models and "slice" them into horizontal layers for the 3D printer to print. This is also where you will be adjusting layer height (affects detail/time of print), supports (needed to print overhangs), print speed/temperature (slight adjustments needed depending on the [[Main Page:3D Printing#Filament | filament]] being used), and other settings. Most printers have a default slicer but some are better supported and most can be used with any printer.

-===[https://ultimaker.com/software/ultimaker-cura Cura]===
+===Adaptive Equipment===
-The default slicer for the UltiMaker devices, but the arguable favorite in the 3D printing community. Actively being developed with updates coming out several times a year, often with industry changing advancements. Can be a bit more complex in advance settings, but nothing that isn't learnable through watching a few YouTube videos. Also has an option for community add-ons which offer several quality of life improvements.
-===[https://www.flashforge.com/product-detail/FlashPrint-slicer-for-flashforge-fdm-3d-printers FlashPrint]===
-The default slicer for the Flashforge devices. Works well with these devices and can be used with other brands of printers, but nothing flashy or special that puts it above other slicers.
-== Modeling Software==
-To edit or clean up 3D models, there are several different programs one can use. Each has different levels of complexity and limitations.
-===[https://www.tinkercad.com/ Tinkercad]===
-A web based design program that allows the user to create 3D models using predefined shapes. Shape dimensions can be modified free hand or inputting precise measurements. Users combine normal and "ghost" shapes to delete portions of objects. While it will load already created STL files, it does have a set limit on file size/triangle account. This is a great introduction into 3D modeling and a good resource to introduce to a patient to create their own project.
-===[https://www.blender.org/ Blender]===
-A free program revolving around 3D modeling and animation. A bit more in depth then other software, requiring time spend watching tutorials or simply messing around to get a feel for the process. Users can modify models on the mesh level by adjust vectors and face or use the sculpting mode for a more artistic approach. Will load most complex STL files and is a great way to combine two models into one (e.g. a [[lithophane]] and a stand).
-===[https://www.autodesk.com/products/fusion-360/overview?term=1-YEAR&tab=subscription Fusion360]===
-Fusion 360 is a cloud-based 3D CAD program that utilizes the cloud storage for easier use in collaboration on complex projects. Another advantage of the cloud platform is that Fusion stores the entire history of the model including the changes to it. Numerous design options are available, including freeform, solid, and mesh modeling. The software is free for personal and noncommercial use, but has limitations on the number of projects stored on the cloud.
-===[https://meshmixer.com/ Meshmixer]===
-While it is no longer being developed, Meshmixer provides straight forward and unique tools in editing mesh models including planner cuts, filling/hollowing models, and creating tubes. While likely not the first choice in creating models from scratch, these tools can be helpful in end stage processing.
-==Filament==
-Fused deposition modeling (FDM) printers use rolls of filament as their material source andare several different types that each have ideal usages, strengths, and limitations. Below are some of the most common types used, but advancements are made each year, so other unique products may be available/best fit for your needs.
