PEI Bed Surface

[jdacal]

Here's what the bottom of the print looks like if you use the smooth side of the PEI surface:

You can see yourself in it! :) Those layer marks on the bottom are actually a reflection, not part of the print.

Nice, the pattern in it almost looks like palm trees.

Yowsers! Beautiful mirror finish!

That's that new photographic filament, I'm surprised you hadn't heard of that one Jim!

Well, I finally put the sheet of PEI on a spare boro and....I'm liking it!!! (I think i could get to liking it as well as the Zebra - we'll have to see how the print removal goes on something bigger than a calibration square.) 55°C for PLA and it sticks all over the bed. (Ran the leveling print - A-okay hunky dory. )

That tape though...........grrrrrrr.

Going to try again, and next time, i'll do it the right way. (Still works, even if it looks diseased, and has a couple of major bubbles from where the adhesive wadded up on itself.)

I'm still loving it except for one thing. I'm finding I'm having to put a lot of my ABS prints in the freezer.

I don't mind that since most pop right of after about 15 minutes. But quite a few of them are still hard to take off, hard enough that when they do pop it stresses the bottom layer and leaves kind of white markings on it. Looks almost like a moisture stain.

I need to experiment a little more with bed temperature. Haven't found a happy medium yet. 80'ish does not bond well for me. 100 bonds great but hard to remove.

Perhaps... 90 might work.

Looks like most of you are using .03 or .06 sheets and bonding them to the boro. Anyone attempt or successfully using a thicker sheet on top of the boro using the bed clips only?

The only problem with that is the same one you have already experienced with the zebra - you have to use the small clips to clamp it down, and even the thinnest 0.03 sheet bonded to the boro is thicker than the zebra. Any thicker and you won't be able to clamp it.

Matter of fact, you won't be able to clip it down without bending out the small clips with a couple pairs of pliers first. Mine barely fit.
