Abstract: Systems and methods for aggregating and analyzing digital manufacturing data are disclosed. An aggregator can collect output data generated by a number of digital manufacturing machines. The output data can be filtered and transmitted to a server for storage in a database. One or more clients can access the data in the database via an API. This can extract 3D printer data, transform it into a canonical form, and upload it to a network-based database. These services can interact using a client-centric messaging system like Kafka or, more generally, a message manager. When a client's producer sends a message, the messaging system responds that the message request either can or cannot be processed. If the message can be processed, then the aggregator sends the message; otherwise the producer can retry at a future time.

Abstract: Embodiments herein describe monitoring the progress of a 3D printing job using a digital twin which can provide corrective actions in real time. The quality of a 3D printed object is dependent on the conditions of different components of the 3D printers such as a heating module, a nozzle, and the level of vibration in different parts, etc. To detect problematic conditions that may negatively impact the 3D printing job, a digital twin simulation of the 3D printer can detect or predict what types of defects have (or will) happen as the object is printed. That way, a corrective action can be taken while the object is printed to either prevent a defect or correct a defect in the 3D object.

Multiple print materials can be printed into the support material simultaneously.

Abstract: The premise of this invention is to improve the methods for allowing one to carve the surface of a hollow core panel or other hollow core materials, such as but not limited to Sing Core, U.S. Pat. No. 7,147,741. In the past, in order to achieve a shallow carving in the surface of the panel one would apply a thicker surface material, or skin material, greater than the depth of the desired carving. Skin materials can be any flat sheet building materials such as plywood, MDF, HPL, fiberglass, wood products, metals, or any other type of flat sheet building materials. Another previously used method is to implant solid lumber that is the same thickness of the core inside the panel. The skin materials can then be pressed over the core and lumber implants. That method works well, but the use of solid lumber creates a weak point across the panel and greatly increases the thermal bridging between each face of the panel.

The display may have a display cover layer formed from three layers of glass fused together. The display cover layer may have outer glass layers that have lower coefficients of thermal expansion than a core inner layer that is formed between the outer glass layers.

An exposed portion of the inner glass layer in the notch may be chemically strengthened.
