Environmental Stress Cracking

Environmental stress cracking often referred to as ESC causes a stressed plastics part to become brittle and crack when in contact with a wide range of fluids that act as stress cracking agents It is the combination of stress and fluid contact that causes failure to occur much earlier than either component could achieve in isolation if at all It is not easy other than by experiment to

PLA not sticking to bed

07 01 2017I have found for getting PLA to stick the best solution (for me!) is to use Kapton tape cleaned with Isopropyl alcohol on a heated bed at 57 0 C I apply the Kapton tape onto the glass after first coating the glass and tape with soapy water Then squeegee the water out and let it dry for a couple go hours It sticks so well I often have trouble getting the print off afterwards

PLA does not stick to glass anymore?

05 01 2013I agree PLA does not easily dissolve in acetone In any case printing to glass is not hard at all if you follow the correct advice You don't need to sand it or add kapton or buy special glass or anything like that 1 Make sure the glass is securely attached to the bed You can use kapton around the edges or a couple of binder clips
