Three Point Leveling
By Mustafa Alkhulaitit – Project Manager
Another minor upgrade that will be applied to the heat bed is what’s called “three point leveling”. The previous heat bed had what people uses on their 3D printers. The most common method used on heat beds is the four point leveling, which is simply having four bolts on each corner of the heat bed to mount it.
This figure shows the positions for the bolts to mount the heat bed- “Four point Leveling”
There are few problems when it comes to using the four-point leveling such as over-constraint and complicating leveling procedure. To fix this issue, the three-point leveling is introduced and is beginning to spread among 3D printer users.
Advantages of 3-point leveling:
- High quality prints
- Reliable printing
- Increase of first layer adhesion
All of those advantages will help us meeting our requirements. All of those advantages depend on a leveled bed, which is a very important point when it comes to 3D printing.
The procedure depends on how many points of attachment are used to mount the bed. Three-point of attachment avoid the problem of over-constraint and simplifies leveling procedure. Three-point leveling uses a triangular pattern that can be seen in Fig.2. There will be only three bolts to mount down the bed instead of four.
