We are working through our terrain catalogue and creating 15mm and 20mm versions of them. This is because we now have a couple of new smaller printers (Kingroon KP3s very heavily modified!) which we have dedicated just for these smaller scales as it is something we get asked for a lot. It will leave our delta printers free to keep on printing miniatures and the bigger Sovols can focus on the larger (28mm and 32mm) terrain. Not to mention our ChironBot - the giant custom printer we built that can pretty much print an entire 8 piece set of 32mm Ulvheim in one go (over a couple of days!) - it's currently running some test prints of a 60mm version of our stone walls as a custom order.
There will be lots more 15mm and 20mm variations coming soon - we are busy with the test prints for the Ulvheim ruined houses and painting up some 15mm sci-fi terrain too. Hopefully we'll be listing all of these in the next couple of weeks, and be able to print enough stock for Reveille in Bristol at the end of the month.
If you are interested in a particular terrain set in a different scale, do please get in touch.
