[Sonic Mega 8K] Replacing the LED

The LED is an essential component of Sonic Mega 8K, as it provides the UV light to cure the resin and create your 3D models. However, the LED may experience wear and tear over time and eventually become burnt out.

Replacing the LED is therefore necessary to ensure that the printer is functioning optimally and producing high-quality prints consistently. In this article, we'll guide you through the process of replacing the LED in your Sonic Mega 8K.
