This is an Ender 3 3D printer, with a few upgrades. These upgrades include a Raspberry Pi that allows more data analysis and enables printing over Wi-Fi instead of requiring to be hardwired. I replaced the main board and added new stepper drivers to reduce noise and smooth out the stepper motor movements. I have added 4 Noctua fans to reduce noise compared to the stock fans. Although the new fans have a reduced CFM (Cubic Feet per Minute), therefore an extra fan was needed to maintain proper CFM with calibrated voltages. The airflow to the extruder provides better cooling to the filament after extrusion, which is very important for overhangs, to improve airflow custom vents were produced to provide more consistent airflow. As well, beside the extruder is an item called a BLtouch. This is used with some coding to find the tilt of the printing bed and adjust the z-axis while printing to perform a perfect print even if the bed is not perfectly level. To the right of the 3D printer is an example of what this printer is capable of. It is a helmet for a future Halloween costume.
