Systems and methods of forming structures on flexible substrates
Embodiments related to systems and methods of forming structures on substrates (e.g., flexible substrates, fabrics, textiles, leathers) are disclosed. In some embodiments, a method of forming a structure on a substrate is provided. The method may involve submerging at least one surface of the substrate into a resin bath. The method may include patterning electromagnetic radiation through a window onto one or more regions of the substrate to polymerize the resin onto the one or more regions of the substrate. An alternative method may involve covering a surface of the substrate with a layer of polymeric powder. The alternative method may include directing electromagnetic radiation toward one or more regions on the surface of the substrate to heat the polymeric powder to form a layer on the surface of the substrate. A method of depositing an ultraviolet (UV)-curable material onto a substrate by a valve jetting process is also provided.

FILAMENT SPOOL DRY BOX
A filament spool dry box includes a shell, a dehumidifier and a sleeve component. The shell includes a hanging structure configured to allow a bracket to be disposed in for hanging the shell. The dehumidifier is disposed inside the shell. The sleeve component is rotatably disposed inside the shell and configured to allow a filament to be disposed on. A central axis of the hanging structure is offset from and above a central axis of the sleeve component. The filament spool dry box can isolate the filament from an external environment outside the shell and remove moisture from an internal environment inside the shell by the dehumidifier. Therefore, the filament spool dry box can prevent the filament inside the shell from absorbing moisture. Furthermore, the filament spool dry box can replace disposable spools in the prior art and be energy saving and environmental protecting.
A DOCKING ARRANGEMENT FOR AN ADDITIVE MANUFACTURING PROCESS
A Docking Arrangement for an Additive Manufacturing Process An operating handle (50) for controlling the operational state of a valve arrangement (26) associated with a container (12) to control dispensing of material from the container (12) to a component of an additive manufacturing process. The operating handle (50) includes a rotatable shaft 56 which is coupled to the valve arrangement (26) and is rotatable between a plurality of angular positions corresponding one or more operational states of the valve arrangement (26). A lever (52) is operatively coupled to the shaft (56) and is configured to cause rotation of the shaft (56) between the plurality of angular positions upon rotation of the lever (52). The handle (50) is also rotatable under the operation of an actuator (40) provided as part of a docking arrangement (10) associated with the component.
RESIN LEVEL DETECTION IN ADDITIVE MANUFACTURING
In some embodiments, a method of determining the fill level of a resin pool in a bottom-up additive manufacturing apparatus includes the steps of: (a) providing an additive manufacturing apparatus including a build platform and a light transmissive window (12), the build platform (15) and the window (12) defining a build region therebetween, with the window (12) carrying a resin pool, the pool having a resin top surface portion; (b) advancing the build platform (15) and the window (12) towards one another until the build platform (15) contacts the resin top surface portion; (c) detecting the impact of the build platform (15) with the resin top surface portion; and (d) determining the fill level of the resin pool from the detected impact.
