- Multiple mounting hole patterns for easy and flexible setup
- A small step for a greener future: craft boxes without bleaching and no coating
3D Printed Housing using PA12
The housing parts are professionally printed with nylon for maximum strength and precision and higher temperature resistance.
Designed With Flexibles In Mind
The LGX For Flexibles Set is a special setup that contains the parts necessary to create, with the LGX eXtruder, a print head that will excel at printing most materials and especially soft and flexible filaments. This set includes a reversible heat sink that can be installed on the left-hand or right-hand side of the cold block. The heat sink also includes a hole pattern for attaching 40×40 fans.
Main Advantages
- Gives access to softer materials
- Enables you to print flexible and soft materials faster
- Keeps the print-head small and lightweight
- Allows for many different mounting options
