raft lifting

[John_Gervais]

I am running a duplicator i3 and abs with the default abs settings but when I test print I find the raft lifting while it is printing. what would the proper bed settings and extruder temp. settings be for abs. I am assuming it is a heat issue.

What adhesive are you using on the print bed?

How are you prepping the print bed? What temp are you running the heatbed at?

Also its been recommend on some printers to slow down or turn off the blower fan while running ABS due to cooling too quickly.

While PLA is VERY recommended that you use a cooling fan, this does not hold true for ABS.

painters tape or such that was sent with the printer

painters tape that was sent with the printer and 245 deg c for the extruder and 90 deg c for the bed

Bed is too cold. Run it 100C+

Painters tape will not really get you very far. You need to prep the surface with ABS juice (google) or hair spray (AquaNet is preferred)

The very best stuff I have found to date is 3DLac - available from Technology Outlet - its not cheap but it lasts a long time and it really works. I have tried pretty much everything (ABS Juice, tape, Pritt Stick etc etc) and this stuff simply does the job. I run the bed of my Wanhao D4S at 60C with no issues

I was struggling with the same problem on my duplicator i3 , and i have tried a lot stuff. But in my opinion abs juice (50%acetone, 50%ABS) works very well. The print will stick nicely on the print bed and you don’t have to change a lot of settings.
