Model to big-need to split it

Without an image to reference, I'm going with a wild guess here. Shape of a frisbee implies a saucer/circular shape, but with contours approaching that of an aircraft wing in cross-section. Too large for the printer requires some guesses as well, in that you may mean you can't lay the "frisbee" flat on the surface of the printer. Such a layout would result in layer lines being placed in parallel with the "line of flight" and may be the strongest method to print.

By the same token, one may not require that level of strength, allowing for layer lines in other directions.

If you split the disk radially, in two pieces, across the diameter of the disk, will the model have sufficient thickness to adhere to the print bed and sufficient thickness to be glued together? As an extension of this concept, if you make the cut across the diameter of the disk but slant the cutting plane to 45°, there will be greater surface area on the cut, more surface area to stick to the bed and to stick to the glue, plus the layer lines will be diagonal rather than perpendicular to the disk plane.

The image above has the cutting plane across the diameter, but has been tilted 45° to the right. The resulting cut is of greater area than if it were sliced vertically. Of course, this is simply a flattened sphere and a frisbee would have much less material, but it serves as a suitable demonstrator.

Another option, if you have the height in your printer and at least one of the horizontal dimensions of your bed is large enough is to tilt the disk. It will obviously require support, but you'll have a good compromise between layer line strength and ease of build.

How about a drawing, sketch or photo of the model?
