If you want to have accurate prints, then you need to ensure the 3D printer has a level bed. As a result, bed leveling becomes quite important. The main types of leveling are manual and automatic. With manual leveling, you need to adjust the screws, which can prove to be tedious and time-consuming. Moreover, the process must be repeated after many prints because of the possibility of misalignment after continuous use.
You should note that an uneven bed can result in problems with the first layer. This can cause poor adhesion of the printed part. Also, it can cause scratch marks on the print and clog the extruder. Many 3D printers feature automatic bed leveling that ensures easy printing.
Every person using a 3D printer agrees that leveled bed is necessary for accurate 3D prints. However, is auto leveling feature necessary? There is a need to understand both the advantages of disadvantages of auto bed leveling.
How Auto Bed Leveling Works
So, how does 3d printer auto leveling work? When it comes to 3D printing, the distance between the bed and nozzle ought to be uniform throughout the build area. However, this is quite difficult to attain, considering the contraction and expansion that takes occurs during the 3D printing process.
Although most 3D printer beds appear even and flat, irregularities do occur because of the usage of tapes and other things that are placed on the bed. Also, mechanical defects in the design of your 3D printer can also result in flaws on the nozzle and bed. Therefore, bed leveling helps compensate for the anomalies on the bed.
Some 3D printers come with the auto level feature. Thus, you can confirm whether the bed is level before printing. Ideally, the printer has a switch the checks various points on bed to ensure the bed is level.
Benefits of 3D Printer Auto Bed Leveling
With auto leveling, it is easier to make changes to build surface without the need of reconfiguring the printer. You can enjoy high precision; no matter bowed build plate or uneven heating. The sensors direct the print head to move parallel to the build plate. Another benefit of auto leveling is the reduction of time spent fiddling with Z height and the platform. Even if you are a beginner machinist, you can easily use this feature. Thus, you can be assured to get accurate prints.
Disadvantages of Auto Bed Leveling
Some experts opposed to auto bed leveling of 3D printer argue that it increases the weight of the print head. Moreover, assembling this type of printer can be time-consuming and difficult. For instance, most printers have a mesh bed auto leveling mechanism that is dependent on induction sensors to measure the distance to the print head. Also, printer firmware can mask errors that make it leveling difficult.
Experienced machinists do not require auto bed leveling. That is because manual leveling of the bed offers you a better understanding of 3D printing, and it is what can make you become a pro. Although this feature is not necessary, it does save time and suitable for beginners. Therefore, when considering buying a 3D printer with this feature, you need to take into account your skill level.
