500 instructions per product is already very tedious and error-prone; much respect for people who can do 6p solves in thousands of cycles without blinking an eye.

I don't think there is a way to do this in finite area without at least two of either projector, purifier or disposal, so I went with the combo of projector and purifier for 5 area total. The real challenge for quantum-bonded products is that you cannot afford to make wrong bonds, which keeps cropping up when you try to make this product atom by atom. What eventually worked was making a diamond shape for the second and third layers before bonding to the rest of the product.
