Threeding is an online 3D printing marketplace and community for exchange and sale of designs and templates to assist in 3D printing. The website provides users with personal storefronts where they can list and sell 3D-printable models to a global audience. Threeding is one of several 3D file repositories that have emerged in the fast-growing 3D printing industry. [1]



Threeding was founded in 2013 by a group of students from the Bulgarian National Academy of Arts. Significant parts of the 3D objects available at Threeding are digital copies of historical artifacts. Several Eastern European historical and archaeological museums have also opened stores and sold 3D printable models of their exhibits via Threeding. [2] [3] [4]


Threeding works in a manner similar to early eBay. In order to sell 3D printing models on Threeding, users register to create a storefront. Creating a store and uploading a product on Threeding is free, and the website charges a commission for each sale, although free exchange of 3D models is also possible and requires no fee. The website has integrated PayPal and major credit cards. [5]

3D printing of cultural heritage

Several Eastern European historical and archaeological museums, including the Regional Museums of Bulgarian cities Varna and Pernik have signed cooperation agreements with Threeding and opened virtual stores. Threeding 3D scans museum exhibitions and artifacts contained in their permanent collections, enabling museums to sell the digital 3D scans through their virtual stores. The available 3D printing models are historical artifacts and architectural features from the prehistoric period, ancient times, as well as medieval and modern history. [6] [7] [8] [9]
