How To Prevent Warping

Why Warping Happens
Warping problem occurs during 3D printing when the printing object is cooling after printing. Cooling causes stress along the object's lateral surfaces. The stress applied on sides causes the corner of the object to pull up and deform. Then, what you see is a warped and unusable printing object. 
How To Prevent Warping
Although PLA filament has a much lower shrinkage factor than ABS filament, both can warp and curl. Here are some methods to deal with this problem. 
1. Use heated bed 
Printing on a heated print bed makes a printed object to cool much more slowly and evenly. Heated bed helps greatly with ABS prints and large PLA prints. 

2. Print with a raft 
Raft is the lower-most layer of your printed object, it helps to reduce warping by allowing your printed object to adhere better to your print bed. 

3. Make sure the first layer is flat
If starting Z axis of your 3d printer is too high, the extrufed filament will not be able to adhere the build platform well. You can try to lower your Z axis by 0.05mm increments until you find a good first layer. 
4. Make sure your build platform is clean
PLA and ABS filament stick better to a clearn build platform. Keep your platform clean is important. 
5. Print slower 
Printing slower allows better adhesion to the build platform and gives the printed object more time to cool evenly.  
6. Enclose your printer or eliminate drafts
The best way to prevent warping is actually to enclose your printer so that temperature remains stable.
