SL Tool Head (Micro) - Small Layer - 0.25mm

The LulzBot SL Tool Head (Aerostruder v2 Micro) is a 3D printer extruder head that is perfect for engineers, digital artists, and designers seeking a higher level of detail and surface quality. Enjoy the convenience and reliability offered by the LulzBot ecosystem including Cura LulzBot Edition software and Marlin firmware. Featuring layer heights less than 1/30th the thickness of a penny, think small with this LulzBot Mini 2 3D printer tool head.

The LulzBot SL Tool Head features a genuine E3D Titan Aero Extruder/Hot End with a 0.25 millimeter nozzle enabling out of the box 3D printing at resolutions as low as 0.05 mm layers, or 50 microns! Advanced users can achieve even finer resolutions.

A high-output centrifugal fan and quad-port cooling duct support elaborate prints with extensive bridging, cooling filament in 360-degrees before it has time to sag between points. Lightweight and compact, the SL connects to your LulzBot Mini 2 3D Printer quickly and easily to bring high-resolution 3D prints to your LulzBot 3D Printer.

This tool head is intended for advanced users, and produces precision prints with impeccable detail.

NOTE: Due to the small nozzle diameter of this 3D printer extruder head, use of abrasive or composite (wood-filled, metal-filled, etc.) filament is not recommended due to the potential risk of clogging.
