Abstract: The present disclosure relates to the use of occluding fluids, such as a high-density fluid (a “z-fluid”) or a low-density fluid (an “a-fluid”), to displace resin within a vat during 3D printing. Further, an a-fluid may act as a protective boundary for a 3D printing resin wherein the a-fluid sits on top of the printing resin. Another embodiment of the disclosure provides a process of assessing which regions of a computer-aided design (CAD) model take advantage of a buoying force supplied by the occluding fluid, such that fewer support structures are needed for printing a final CAD model compared to printing the CAD model without the occluding fluid.

Abstract: The trays (V) are provided with identical vertical spacers (4) which enable the trays to be stacked on top of each other in a centred way, with a suitable spacing betweem them, and enable the various adjacent stacks of trays to be raised and lowered in steps, by means (BM) which act only on the bottom tray of each stack. The sides of the stacks of trays of the kiln are thus free and can be engaged by conveyors (37-37′, 77-77′, 57-57′) of the means provided for the translation of the trays between the stacks, both in the normal operating cycle and in the short operating cycle. However, the lower translation conveyors (24-24′) which transfer the trays from the stack with the unloading station (K2) to that with the loading station (K1) are positioned in the usual way under the stacks of trays and transversely with respect to the trays.
