Generally, a 24V extruder can heat up faster and maintain a more stable temperature compared to a 12V extruder. However, using a 24V system may require additional safety precautions due to the higher voltage. It is important to consult the manufacturer's recommendations and specifications to determine the appropriate voltage for the extruder to ensure safe and efficient operation. **

This type of ink also provides a rich and vibrant color when printed onto paper. **
