This is the first draft of the large scale 3d printing protocol for granulated thermoplastics. The main purpose of this document is to share the key steps of operating, preparation, data entry, and optimization procedures while handling the robotic 3d printing equipment. One main aspect of this protocol is that it is independent of specific 3d printing hardware or software setups. The aim is to have the users from robotic 3d printing from various technologies follow these steps and be able to set the basics up when it comes to handling such 3d printers.
