Lazy annealing of PLA (covered on heated bed after 3D printing)

Annealing of the PLA will improve properties of the printed object, mostly temperature resistance, but the object will deform during this method. Using the oven is not too accurate method and uses too much energy. Heating covered on 3D printing bed is simpler solution and saves energy too. But is it worth it? Let’s find out..

In this test I used Amazon Basic PLA and everything was printed on Ender-3 S1 Pro.
