My FDM printer (Ender 5 Pro) has been working non-stop on some terrain that turned out rather good. The terrain is from a Kickstarter called Isolation Protocol Terrain, so I am not certain it is still available. However there is quite a bit that you can make with this set and I still have some more ruined buildings that I have parts printed out for. These definitely turned out good with stairs and bridges that can be placed where you want them.
I will say that all of this took a couple weeks to print out and yet.... only a day to paint up as you see it. However the results are fantastic.
I started printing these in white PLA and learned something interesting.... print it all in black and priming will be a little less tedious if you happen to miss some deeper details while priming.
There were some issues I had while printing which I have as of now attributed to the PLA I was using. It was a nightmare in many aspects and have now moved to a different brand SUNLU which seems to adhere better to the build plate and do overhangs with a ton less difficulty.
