Advantages: 

• Excellent Adhesion
  For most of the filaments like pla, tpu, wood, petg ect, it stick well. Unlike the PEI-powder cotated plate, the prints will fall off automatically after power off,  the PEI filmed plate has no problem to resume printing after power off.  
  
  
• Super Easy to Remove the Prints
  No need any tools, just bend the plate, and the prints will pop off.
   
• Repeatable Use
  Compared with PC magnetic flexible plate, the PEI Film is easier to replace by spraying the alcohol and removing.
  
  
• Very Smooth and Clean
  As the PEI Film surface is very smooth and clean, the bottom of the prints will be very smooth and clean too, for some filament, the bottom of the prints would shine like a colorful mirror. 
  
  
• Wearable Resistance Durable
  The PEI film, stainless steel, magnetic base, every parts are made with high-quality material, it is very durable, and wearable, the scratch would not be obvious and doesn't affect the printer quality a lot.
  
  
• High-Temperature Resistance
  The max temp can be 110c, easy to print with some high temp filament.

Installation guide: 

1. Tear off the back adhesive, stick the magnetic build plate on the surface of the heated bed. If you find air bubbles, during installation, please tear it off and stick it again.
   
   
2. Put the PEI flex plate on the magnetic build plate.
   
   

3. level the heated bed first. Keep the distance between the nozzle and the heated bed within 0.1mm（A4 paper）, about a sheet of paper thickness at the best.

4. After completing printing, please take off the PEI plate until the heated bed has been cooling down. You can gently take off the model by bending the PEI flex plate.

 The installation is the same as the flexible magnetic plate below.
