Replacing Broken Plastic Parts with 3D Printing: A Step-by-Step Guide

In today's Filament Friday, we will delve into a practical solution for replacing broken plastic parts using a paper scanner and 3D printing. Often, when faced with a broken plastic piece, the immediate reaction is to buy a replacement or search for designs online. However, the process of scanning and 3D printing the part yourself can be a rewarding and cost-effective alternative.

Scanning the Broken Part

If you have a broken plastic piece like a clip, for instance, that needs replacing, you can start by scanning it using a simple paper scanner. By gluing the broken pieces together and carefully placing them on the scanner bed, you can capture the part's image effectively.

Use a paper scanner to scan the broken part.
Ensure the broken pieces are glued together securely.
Place paper over the part to prevent glare during scanning.

Editing the Scanned Image

Once you have scanned the broken part, you may need to edit the image to remove the background and make any necessary touch-ups before converting it into a 3D printable file.

Use image editing software to remove the background.
Fill in any spots or imperfections in the image.
Convert the edited image into an SVG file for 3D modeling.

Modeling the Replacement Part

With the SVG file ready, you can import it into a CAD program like Tinkercad to create a 3D model of the replacement part.

Import the SVG file into a CAD program.
Resize the model to match the original part's dimensions.
Adjust the height, width, and length of the model accordingly.

Generating the 3D Print File

After modeling the replacement part, export it as an STL file that can be used for 3D printing. Prepare the file with suitable settings for optimal print quality and strength.

Export the modeled part as an STL file.
Set printing parameters such as layer height, shells, and infill.
Print the part using a 3D printer, ensuring proper adhesion and support.

Testing and Implementation

Once the 3D printed part is ready, test it by fitting it into place to ensure it functions correctly. In this case, the newly printed clip should securely hold the cable in its place.

Test the 3D printed part for proper fit and functionality.
Verify that the dimensions and design match the original part.
Implement the 3D printed part for practical use.

In conclusion, by leveraging the combination of scanning, modeling, and 3D printing, you can effectively replace broken plastic parts with ease. This DIY approach not only saves time and money but also allows for customization and creativity in addressing common repair needs.
