ABS-Printing: When should ambient temperature reach to which value?
Hi,
I want to know when the temperature within enclosure should reach which value for successful printing ABS objects?
- From the beginning?
- At begin of 2nd layer?
- At begin of Xth layer?
I did test and the temp reached 33Grad celsius when the first layer was finished. Of course it matters how much on the first layer is printed since the smaller the footprint, the shorter are there time to heat.
My enclosure doesn't have active heating, so it passively heated by the printer. But the cooling is temperatur controlled. I'm using isolated rack-cabine (commonly used for servers 😉 ).
Best regards

I would submit to you that its dependent on the material being used (different manufactures produce ABS's with different quality's) as well as the models shape and size plays a large roll in the correct answer for you, I think your best recourse is to play, experiment and have fun doing it, and you will develop a feel for your system and what it takes to succeed using it.
Good Luck have fun

RE: ABS-Printing: When should ambient temperature reach to which value?
I've been playing around with the control points for the temperature in the enclosure (homebrew RPi fan controller) and I've found that temperatures in the low-mid 30s range seem to work quite well for most filaments.
After using the enclosure for a few months, I would say that the enclosure itself makes more of a difference than the particular temperature inside.

Hello Schweizer-Käse 😉
thank for your reply. Of course it matters which material and quality you use as filament. I was hoping to know the moment, when the temperature should have.
Currently my prints are well somewhere 3-5mm. Then it start warp while the temperature sensors displays somewhere 30-33 grad celsius (don't remember the exactly value). I'll close the remaining holes (drillhole, cutout hole, etc...) and warm um the room before start the printing.
I'm using ABSpro Flame Retardant.
I believe I need a heater for preheating the chassis. :/
@jsw: You said, the enclosure itself make more of a difference. Could you explain more about that?

@jsw
I have had a similar experience and great success in the mid 30s.

As far as a difference, the big one is that I no longer need to use a draft shield to be confident that I'll get a good ABS print.
I think successful ABS prints depend on many factors, each which will add a bit to the mix, but when combined it's kind of like a Gestalt thing. Some of the things that I've found that help with ABS prints include:
Always use a release agent. Lately I've been using Layerneer Bed Weld. I'll spare your eyes from yet another view of the photo of the bottle. 😉 Be sure to cover the corners of any large flat pieces to avoid warping and curling-up off the bed.
Preheat the machine. Let it sit and stabilize 10-15 minutes or so before launching the print.
Use an enclosure or a draft shield, preferably the former.
When the print finishes, let it cool to almost room temperature before trying to remove it.
Avoid the temptation to use metal instruments to help 'persuade' the print to release. I learned the hard way on that one!
ABS is a good material and produces very strong prints. I regularly use it for small trim pieces such as window frames on model buildings that will be press-fit into window holes and have a so-called-clear pane piece pressed into them.
