longest print to date - 8 adaptors at once, took 5 hours plus.
perfect.
And it actually finished a couple minutes after I got back from a job. And while being held firm, they popped off the bed while hot with no problem.
Not sure whether it's the fact that this stuff is perfectly flat or what. But the prints are coming out better than ever.
Even tape is not perfectly level, and gluestick tends to thicken up over time. So you'll get tiny imperfections in that.

But because you never need a scraper with this and nothing gets added or removed it should last indefinitely, the printing is definitely better.
The bases are mirror smooth.

All in all I'm impressed.

I'll try polycarbonate next.
