printing environment

Recommended Posts

Hi guys, I'm just wondering, how many of you run your printers in temperature / humidity controlled environments? such as an air conditioned office?

The last few days here in Sydney have been hot and humid, and my UM2 has been under extruding a lot, using PLA

It's cooler today, but humidity is still at 65% so I'm running a portable air con unit in the room.

Printing a test now, a small cube, at 0.06 layer height, that was under extruding, even at 250 degrees the other night. Right now, printing at 230 degrees, and it seems to be going well.

I'm wondering if humidity can cause a sort of sticking in the bowden tube.

Well, the difference today would make you think the prints came off different machines. Also noticing though, the blue ultimaker PLA doesn't seems to print as nicely as the orange, even when not under extruding, the surface finish isn't as smooth at the same speed and layer height.
