Silicone sock over 300C?

Bambu Lab H2D
1

On most silicone socks I see they’re rated to 300C and it is recommended to remove them if printing over 300C.

I noticed on the product page for the H2D sock the upper limit is not listed.

Is the design of the H2D extruder as such that it can do 350C with the sock on, or is the limitation not being clear just an oversight?

I don’t want to ruin a sock (even though they’re cheap) by printing high temp stuff.

Is it safe for the printer to run 350C with the sock off?

The filaments I’m looking at are 320-330C - while I don’t intend to print with them a lot - I have a few projects coming up where I will.

TL;DR - can the sock on the H2D handle 300C+ print temps and will printing without the sock damage the printer in any way?

The function of the sock is to prevent the heat from escaping. If you run the hot end without it there is a high chance the heater wont be able to keep the hot end at operating temperature.

I have printed PPA and PPS both at higher temps than standard (for better layer adhesion), close to 350c without any problems or damage to the sock.

TLDR - use the printer like it was designed and keep the sock always on.

My intention isn’t to run it without a sock, I just was more trying to figure out if I will be replacing the socks often if I am running over 300C.

I have some spares, but haven’t ever done printing that required over 300C before so this is new territory for me.

Ive had to replace both of mine already. They tend to tear at the rib between the two holes. I wound up ordering 40 pack from aliexpress for $18, I would suggest you inspect them often.

Oh nice, I ordered a few packs from Bambu, so I should hopefully be good to go for a bit.

Are you sure those can handle 350C also?

Ive printed both PPA and PPS which I print at close to 350c for better layer adhesion with no problems. Also they have not ripped yet, still on my first ali sock set.
