Why an Heated Chamber at 90°C

I made tests with my ABSolute using ABS and different temperatures of heated chamber…

The part is very simple : a Square 170mm, 5mm thickness, 50mm height

It looks very easy to print, especially with a printer with Heated Chamber…

In fact no… Not so easy, I print this square with my ABSolute 2 and a Chamber at 75°C, the part still warps !

And these warping create stripes on the part easy to see with low-angled light

The same file printed in a 88°C chamber… Same print parameters except chamber temperature

Result :

Even with low angle light

The print is very nice, zero tension in the part, zero warping, zero mark !

These 13°C make the difference.

If you want perfect prints, you need 85°C heated chamber, minimum… 70°C or 75°C is not enough for large parts in ABS.
