High-temperature Resistant Teflon Tube: LK5 Pro 3d printer's teflon tube can withstand high temperature which up to 280℃ (others printers are 250 ℃ in normal), is not easy to soften, and is easier to feed filaments during printing which helps to improve the printing quality and reduce nozzle clogging. Exceptional circumstances may extend this time frame (such as holidays, snowstorms, heavy rain, or COVID-19, etc. This is the first 3D printer I have used that has a triangle structure Z brace and a high-temperature resistant Teflon Bowden tube. The layer cooling fan duct was too far away from what it’s cooling and pointing too much towards the 3D printer nozzle. The power resume function on the Longer LK5 Pro works if you catch it in time before the heated build plate cools down.

The FDM 3D printer is equipped with an upgraded ceramic coating glass for easily peeling off from the printer's base. The result of using the high-temperature resistance Teflon tube is reducing and eliminating clogs inside the printing tube nozzle. Loved printing this 3D model very high detail that the Longer LK5 Pro budget 3D printer handled pretty well even for the smaller Harley Quinn and Poison ivy.

You won’t be able to use the supplied spool holder as it won’t work because the pen holder needs to be placed on the left Z extrusion.

lower installation inclined material rack, low centre of gravity does not shake, oblique into more smooth.

Being a professional 3D printer, the LK5 Pro is equipped with a high-temperature resistance Teflon tube to stand up to 280℃. The LK5 PRO is integrated with 3kits of TMC2208 chipsets for the X / Y / Z axis for quiet printing, which will be reduced noise from the motor.
