An improved 3D printer includes an airflow enabled print bed ensuring secure placement of a print base prior to printing. The modular assembly technique provides for improved ease of manufacture and assembly, as well as adjustments of print sizing. The improved printhead includes a heat sink disposed internally therein for improved heat and cooling properties. The printhead itself includes z-axis position detection techniques. The inclusion of VSU insertion techniques in software modeling and printing further improves the print operations by including vertical stability for the print object.

Three-dimensional printer

A 3D printer calibration system and method includes a controller controlling movement of the 3D printer printhead in a first axis, such as the z-axis. The printhead includes a hotend for depositing material to generate the 3D printing. The hotend is connected to the printhead via a connector being moveable along the first axis. The hotend further includes an arm that extends outward from the side of the hotend. An optical sensor assembly is affixed to the printhead, the optical sensor assembly that has a light emitter and a light detector. The controller calibrates a starting position for the printhead based on the first axis deflection of the hotend as detected by the optical sensor assembly. The connector allowing first axis deflection of the hotend distinct from the first axis movement of the printhead.

Printer head z-axis alignment method and system

A method, storage medium and system for routing data messages between a plurality of processes running on a plurality of computers connected to a network, at least one routing process acting as an interface between each application process and other application processes and routing processes, each data message including data and indicating at least one property of the data, including at least one routing process that receives at least one interest message of at least one application process and incorporates information from the interest message into a data structure. Each interest message has information including the identification of at least one property of the type of data messages that the respective application process is interested in receiving. A first routing process receives a first data message from a first application process, compares at least one property of the first data message with information included in its data structure and determines which among the plurality of application processes is interested in receiving the first data message.

Method, storage medium and system for distributing data between computers connected to a network

A data management and distribution system has been described that includes router processes for controlling data communications between child processes running on computers connected by a network. Preferably, a router process runs on each computer, with the application processes running on the computer connected directly to the router process. As a result, all interprocess communications must pass through the routers. Each router process includes a connection table listing its connections with all other router and application processes, as well as an interest table listing the type of objects that each of the other processes are interested in receiving. Data communication is accomplished by an application process providing an object to its local router, which then distributes the object to all other interested routers. The object includes a destination list indicating which processes are to receive the object. Thus, with the use of routers, application processes that need to communicate with each other over a network need not know the intricate details (such as the communications protocol used, the exact address of the receiving process, etc.) involved in transmitting information. By placing the burden of managing the network communications on the local routers, the complexity of the application code is reduced since it has only a single connection to its local router.
