3D Printed Nasal Dilators

In resource-limited countries, access to basic medical devices is limited and expensive. This project proposes manufacturing nasal dilators using 3D printing as an accessible and affordable alternative, improving patients' breathing and promoting domestic production.

Supplies:

Materials Used

1. PLA filament (used for the initial prototype)
2. TPU filament (used for the final version due to its flexibility and comfort)

Tools and Equipment Used

1. Creality Ender 3 (FDM 3D printer)
2. Fusion 360 (for 3D modeling and design)
3. Cura (for slicing and print preparation)

Measurements.

For our first step, we will use the measurements required by the user to design the nasal dilator, taking into account comfort and effectiveness. The goals are to achieve a symmetrical structure with rounded edges to avoid discomfort, and to regulate the thickness so that it is neither too thin nor too thick.

Import the STL file into Cura.

Adjust print settings (layer height, infill, temperature, and speed) according to the filament type (PLA for prototype, TPU for final version).

Generate the G-code file.

Print the first prototype using PLA filament.

Evaluate shape, size, and structural integrity.

Why PLA?

PLA is used for the initial prototype because it is easier to print and helps evaluate the shape and structure before moving to the final flexible version in TPU.

Based on the prototype results, modify dimensions or thickness in Fusion 360 to improve comfort and functionality.

Evaluate the fit and make small adjustments to curvature, width, or size to improve stability, airflow, and overall comfort before printing the final TPU version.

Print the final version of the device using TPU filament to achieve greater flexibility and comfort.

After printing, carefully inspect the piece to ensure it has smooth edges, proper shape, and no printing defects. If necesary, lightly clean or trim any rough areas so the device remains comfortable and safe to wear.

Test the final version for fit and overall comfort.

Check that the device maintains its shape while still allowing flexibility, Also confirm that airflow improvement is noticeable during use and that breathing feels easier compared to without the device.

This are the G Codes of our project.
