These models are manufactured in house at Tabletop Heaven using liquid resin SLA 3D print technology. A special blend of resin is used to make the models more durable than standard 3D photoresins, while still maintaining a high level of detail and smooth finish on the models. The models are all washed and cured and the supports are removed prior to shipping. Prints are supplied unassembled and unpainted and may have minor flash, or blemishes, remaining after the supports have been removed. Prints are made to order and may take up to one week for dispatch depending on order volumes. If you have any issues with your models please contact sandy@TabletopHeaven.com and I will be happy to work with you to ensure you are completely satisfied with your purchase.
