Preventing warping when printing 3D ABS objects

February 17, 2013 · admin 3D Printing Prusa Mendel ABS

The biggest issue when printing 3D ABS objects is warping. As an example, this 8 cm x 8 cm bit holder is badly warped. In this example, 5 mm. !](http://www.ctheroux.com/wp-content/uploads/2013/02/dremel-bit-holder-warpage.jpg) Adding disks (1.5 cm x 1 mm) at each corners prevents warping almost completely. These anti-warping disks can be easily added on the plater of Slic3r. The printing end result printing is shown on the picture below. 1 cm x 0.6 cm disks also works fine.

I was not able to reach 110 Celsius with a Prusa PCB Header Bed MK1. My initial installation was with the PCB traces down with a borosilicate glass on top of it. I found out that installing it with the traces up as show below resolved the issue. Nevertheless, the thermistor does not read the real printing area temperature since it is underneath the PCB. There is a 15 Celsius offset and the glass is slightly offsetted. These are small inconveniences. The bed is getting hot pretty fast and is able to reach 110 Celsius.
