This is a drop in All Metal Conversion kit for the LNL 3D printers. It requires absolutely zero modification to your printer to install. With the all-metal hotend kit installed, you'll be able to print all kinds of high-temp materials using your LNL printer : Nylon, TPU, ASA, PETG, PolyCarbonate and PolyPropylene. You'll also be in the perfect place to upgrade further, by installing a Hardened Steel Nozzle, allowing you to print abrasives such as NylonX and NylonG.

• This Heatbtreak is made from two components, Copper and Titanium TC4. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. The inner wall of the titanium is very smooth Plus the DLC nano coating so that the filament can pass through very smoothly and stop clogging. This special Nano Coating called DLC, DLC Nano Coating not only has excellent wear resistance, but also has a very low friction coefficient and excellent corrosion resistance, with a generally smooth surface, better for filament feeding.
• this hardened steel nozzle has higher toughness and hardness, not only suitable for common 1.75 mm 3D printer filaments, but also can print filaments of carbon fiber, fiberglass, etc. The inner wall of the MK8 nozzles is smooth and has no burrs, the viscosity coefficient is small, extruder nozzle diameter error less than 0.02 mm, provide you an accurate and smooth extrusion. MK8 extruder nozzles are made of hardened steel, good abrasion resistance, heat resistance and corrosion resistance, sturdy construction makes them durable to serve you for long time, suitable for 3D printing at high temperature.
