All of our terrain pieces are printed using high quality PLA plastic at a .16 layer height resolution. We pride ourselves in printing at a much higher quality then out competitors. Terrain models are Print to Order, meaning we will not start the print until your order is received. Please allow for up to a week for printing and processing before your order is shipped. Terrain products are 3D printed and as a result of production, the models may require some sanding, trimming or assembling. There also may be some fine layer lines, these lines can be minimized by using a spray-on filler primer before painting. All pictures of finished products are for examples only.
