    While electrical parts with the Longer LK4 3D printer were installed and secured, I had to assemble the rest of the printer. It took about 45 minutes to set up and begin printing. The printer is made of a sturdy aluminum frame that is long-lasting and gives the machine a stylish look. You’ll also notice the printer has a filament runout detector and can make quality print offline.

    You should have some knowledge about 3d printers before purchasing. It is really difficult to level the heated bed because it is not entirely flat. The bed leveling knobs are small and make leveling the bed difficult. There is no auto-bed leveling feature but is equipped with a five-point assisted manual leveling setup and the cooling fans are pretty loud. Overall, the build volume is very good and prints are smooth and well detailed. With the resume print and filament runout detection, it’s a great model for the price.
