  • Patent number: 11897720
    Abstract: 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.

  • Patent number: 11884015
    Abstract: A system and method for facilitating separation of 3D-printed objects from build platforms. The principle of separation in the present invention involves a build platform configured to be removable or flexible or partially deformable, such that at least a portion of the build platform may be bent or tilted to separate the build platform from the 3D-printed object once the 3D-printing is completed. In some embodiments, a base assembly is adapted to magnetically move a build plate along a surface of the base assembly such that the build plate automatically self-aligns along a boundary of the base assembly and magnetically couples to the base assembly. In some embodiments, a build platform includes a flexible layer with a printable surface and a rigid layer coupled to the flexible layer so that applying a force on the flexible layer deforms a localized portion of the printable surface without deforming the rigid layer.
