The invention is generally a nasal pharyngeal and oral swab that may be mass-produced via three-dimensional (3D) printing. To achieve the right materials for 3D printing the swabs, exemplary embodiments employ a set of materials that result in a rigid structure that has bendable properties (at least in the neck or stem region of the swab), but more rigid and bridle properties at a breakpoint of the swab. In exemplary embodiments, this may be achieved by constructing the device of a first photosensitive material that is generally soft and bendable when cured, and a second photosensitive material that is generally rigid and brittle when cured, wherein the soft bendable material comprises of about 70% to 90% of the photosensitive composition used to 3D print the swab, and the rigid and brittle material comprises of about 30% to 10% of the photosensitive composition used to 3D print the swab.

System and method for facilitating separation of stereolithography 3D-printed objects from build platforms
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.

Apparatus, system, and method for use in three-dimensional printing
The present invention concerns a reservoir assembly for use in three-dimensional (3D) printing for building a 3D object, which includes a top frame that may be filled with liquid material, and a tensioned film being held underneath the top frame. The tensioned film may be air permeable and elastic at the same time, wherein surfaces of the tensioned film are micro textured so that the tensioned film becomes optically clear when it contacts with the liquid material. The tensioned film minimizes the creation of bubbles between the top and bottom surfaces. This also helps blurring the boundaries thereby enhancing the surface finish of the fabricated parts.
