Additive Manufacturing Enhances Custom Splint Design and Patient Adherence

Research Explorer (The University of Manchester) · 2012

Key Findings

01Additive manufacturing allows for the creation of custom-fit splints with integrated novel features.
02A specialized 3D CAD methodology is crucial for effectively designing splints with AM capabilities.
03Improved aesthetics, hygiene, and fit through AM can positively impact patient adherence.

Application

Design takeaway

Integrate additive manufacturing and user-centered design principles early in the design process for medical devices like splints to improve both functionality and user experience.

How to apply

When designing any form of wearable medical device, consider how additive manufacturing can enable greater customization for improved fit, comfort, and patient engagement.

Project actions

01Consider how patient feedback can directly inform the design of custom medical devices.
02Explore how different materials can be combined in a single print to achieve varied properties (e.g., flexibility and rigidity).

Method & Evidence

AimHow can additive manufacturing and specialized 3D CAD methodologies be employed to develop custom-made wrist immobilisation splints that improve design efficiency and patient adherence?

MethodDevelopment and evaluation of a novel CAD methodology integrated with additive manufacturing capabilities.

ProcedureThe study involved developing a specialized 3D CAD methodology tailored for splinting practitioners to design custom splints. This methodology was then used to create splints with integrated novel features enabled by AM's multi-material capabilities, with the aim of evaluating their impact on adherence factors.

ContextMedical device design, specifically orthotics and splinting.

Variables

IVAdditive manufacturing and specialized 3D CAD methodology.

DVDesign efficiency, patient adherence (influenced by aesthetics, hygiene, fit).

CVType of splint (wrist immobilisation), specific AM technology (Objet Connex).

Strengths & Limitations

Strengths

+Addresses a clear user need for improved splint design and adherence.
+Explores the innovative application of multi-material AM.

Limitations

The complexity of the CAD software and the cost of multi-material 3D printers can be barriers to implementation.

Reliability & validity

The validity of the findings regarding adherence would be strengthened by direct user trials and long-term follow-up. The reliability of the CAD methodology would depend on its consistent application by practitioners.

Think critically

To what extent can the benefits of multi-material additive manufacturing for custom splints be generalized to other types of personalized medical devices or consumer products?

Design Principles

"Personalization through advanced manufacturing technologies can significantly enhance user adherence and satisfaction."

Traditional splint fabrication is often time-consuming and can result in patient discomfort or dissatisfaction due to poor aesthetics and hygiene. AM offers a pathway to create highly personalized devices that address these user-centric concerns, leading to better treatment outcomes.

What This Means for Your Design

Using 3D printing to make custom splints can make them fit better and be more appealing, which means patients are more likely to wear them as prescribed.
