The LGX can also be ordered to come with different add-ons including the LGX Shortcut and the LGX ACE. The LGX Printheads are the combination of these add-ons with the LGX.

The LGX™ Shortcut is a special hotend that mounts to the side of the LGX™ eXtruder. With the LGX™, it forms a print head that will excel at printing ALL most common materials and especially the soft and flexible. This add-on comes in two variants: Copperhead® and Mosquito®

The Bondtech LGX ACE Hotend is an add-on attachment that mounts to the front of the LGX eXtruder. The different variants (Copperhead®, Mosquito®, Mosquito Magnum+®) of the LGX ACE Hotend are designed for rigid and flexible materials, improved cooling capacity, and high flow rate applications.
