Biodegradable pla resistant at 140°c

VOLUMIC’s ULTRA PLA has a little-known property. That of being able to move its glass transition threshold (TG) from 50° to 140°.

What you are looking for when an object printed in PLA Ultra is annealed:

First increase its TG (up to 140°C) then slightly increase its resistance. The double advantage of this process is that it does not alter the aesthetics/finish of your room. In order to take full advantage of the annealing process, the piece must be printed with a 100% lineal fill. (the part must be full)


The processes are as follows:

In water:
1. Immerse your object with a light grid (so as not to deform it during annealing with the weight) in water at room temperature.
2. Bring to a boil and boil for 10 minutes.
3. Turn off and allow to cool gradually.

In an oven:
1. Put your object in the oven at room temperature.
2. Heat slowly to 95° and cook for two hours.
3. Turn off and let cool as gradually as possible until it reaches room temperature.

Do not open the oven in the meantime so as not to create a thermal shock that could cause the baking to fail!

NB :Prefer the oven process because boiling with bubbles and other swirls could overheat (and therefore damage) the piece.

The annealing process (water or oven) causes a shrinkage on the PLA that must be taken into account on the dimensions of the parts in question if they are accurate. A loss of 2 to 3 tenths less once annealed is to be expected.
