I'd suggest no more than a 15% infill, and a 0.15mm layer height. That would cut down print time per piece, I wager. These pieces are BIG, so will already have some heft, especially when assembled, so don't need extra infill to keep them on the table, I expect. The piece as a whole, assembled, looks to be around 2'hx2'x1' on the table, so I can see it taking a while. Would recommend PLA rather than resin, both for durability and for cheapness. But won't be getting to it soon myself. Eventually.
