ABS temp???

@Geit, I have a question about ABS. My wife lost the air concentrator for her hair dryer. She asked if I could print a new one. I quickly designed one and printed it with Hello3D PETG Carbon black filament. It printed beautifully; I mean really beautiful. As I’ve noted before about this filament, it’s difficult to even see any layer lines. However, I warned her that it may not be able to withstand the hair dryer’s temperature. And that turns out to be the case. I tried it for about a minute this morning and it softened quite a bit. Obviously, I don’t want her using it for her hair. I don’t want to take a chance that it will emit nasty fumes for her to breathe in.

So, my question is: do you think ABS would work for this application? Could it withstand the temperature?

Says it can withstand temps of up to 85 C before starting to deform.

That’s too low.

found another website that says it can go as high as 100 c.

Yeah. PETG can do similar, so still no go. Oh well, tough luck.

Most likely your best bet would be nylon but without an enclosure printing anything but a small part can be very difficult if not impossible.

Well, it starts to get a little soft at around 100 to 105°C. This does not mean it instantly fails at that temperature. If so we would just use 100°C to print ABS. We usually are at least 120°C hotter than that.

It starts to get a little soft. If you make the nozzle walls of a decent size it could work as it softens on the inside first, while the outside acts as a heat sink. I would give it a try with a 1-1.5mm wall size and a solid wall.

I could imagine that the usage time is not even the worst case. I think it is the moment when you turn it off. The heated air is stuck in the nozzle. Even with my hair dryer, I use the cold mode for a few seconds, before hanging it back to the wall. Usually happens automatically as the cold mode is beyond off. So I switch from 3 to cold, back to off. :smiley:

It is an interesting project, you have the model and a reason to do some practical printing. What can go wrong?

It did soften quite a bit, especially the outlet part. I hadn’t thought about using the cold air setting. My concern was that it might release fumes while hot. With her compromised immune system, I don’t want my wife breathing any filament fumes.

The design took very little time: a couple of lofts, and shells, and it was done.

BTW, it fits the hair dryer like a glove :slight_smile:
