I printed some 1/144 scale Halberstadt D-II fighters yesterday, and they turned out not to be without issues. Issues which I didn't notice, alas, until it came time to remove the supports to reveal the printed model underneath.
Each of them printed with a semi-broken back, probably because the models were printed tail-down at about 60° to the build plate, and lacked any supports along the underside of the fuselage, so they sagged just a little bit before the upper layers started printing.
I've rebuilt the gcode with more supports in the problem area and I'm trying another one; we shall see how that turns out.
They also all printed the tail fin poorly. I added more supports there too, but that problem isn't nearly as troublesome to me.
They're all usable as gaming models, even as they are, but I would prefer it by far if they were less flawed.
A few days later
Here's one painted in a livery for late 1916-ish. At some point in 1917, I'm not sure exactly when, the official colours changed from green and brown to green and mauve.
This particular model was printed split into two pieces, with the fuselage cut just behind the lower wing. It improved printing of the tail section quite substantially, but the struts are all pretty grungy.
