11577462 · 2023-02-14 · ·

In in-process inspection or calibration of a print bed or 3D printed part with a 3D printer, toolpaths defining printing material shells for deposition by a 3D printer are compared to surface profile scans from a range scanner to identify differences between the print bed, instructed deposition and the measured result, permitting pausing or alteration of the toolpaths or printing process.

3D printer and inventory control and distribution system for 3D designs

A digital platform enables 3D printing where the designs are protected from piracy/redistribution. A single board computer (SBC) communicates with a first server and a second server. The SBC requests a unique hardware ID from the first server, which assigns and sends the ID to the SBC. The SBC submits the ID and a secret key to the second server to request registration of a user and a printer, and the second server sends private certs, a client ID, and a unique public identifier to the SBC. The second server also receives and stores 3D print designs through a designer portal, and on-demand displays the designs in a GUI screen. The SBC user may purchase a 3D print design, and the second server, in response, sends an access token to the SBC. The SBC redeems the access token for a selected 3D print, and the second server adjusts geode for the selected 3D design for the particular printer, and streams the adjusted geode to the printer through the SBC, thereby protecting the code from unauthorized user/replication.

20230234293 · 2023-07-27 ·

Embodiments represent acceleration along three orthogonal axes at two or more times as a three dimensional plot. Each point in the plot is positioned according to three coordinates, each of which is proportional to the amount of acceleration along one of the orthogonal axes at a moment in time. Some embodiments render the three dimensional plot as a three dimensional article of manufacture in which each point in the plot is represented by a volume of material. Some embodiments represent the three dimensional plot in two dimensions in a graphical interface. System embodiments may include an accelerometer, processor, output device, and a non-transitory computer readable medium storing instructions causing the processor to map points with coordinates proportional to acceleration along the respective axes to a virtual three-dimensional plot and then control the output device to render the plot in two or three dimensions.
