Topic: Adding Citric acid and PE to PLA pellets

Hi,

I just bough some PLA pellets from australian cardia bioplastics BL-F02 - the resseller said that, to make filament from this PLA you have to add 1% of citric acid and some PE to make it less brittle and adhere better to the heatbed.

Anyone tryed any of this 2 things to PLA? Does it make any sense?

Thank you!
