We recently posted a new support article about how you can change the hardness of TPU 90A on Fuse with just some different power and scan spacing parameters: customer_v2
Here are three .fps files that we used when doing that testing, for 80A, 60A, and 40A. By 40A some things like finer lattices start being a bit harder to get out, but not impossible! Good luck
