Prusa 3D Printer Data Input Modificiation

Client

Problem Statement

In order to adhere to Navy Cybersecurity Regulations, conventional file transfers through wifi, bluetooth, SD, and USB is prohibited.

Concept of Operation

Solution

  • Rewiring the SD card slot on the printer to the microcontroller using an SD Card Prototyping Board.

  • Establishing a connection between the microcontroller and the USB DVD drive using a Host Shield.

  • Reading data from the DVD and storing it in the microcontroller's external memory.

  • Making the stored data accessible for the printer to read and use for printing.
