I mean you can try until enough users own this machine. By reading the instruction FL sent to me, they already chipped the cartridge which means you can only use their powder for the sake of better material consumption management. But I guess once we have enough users, someone will figure out a way to bypass this material lock.
For the cost, you can use Preform to check. There is Fuse1 profile already inside and you can load files to check the production cost.
Honestly speaking, based on my experience, nylon machine requires a maximum space using rate to lower the percentage of waste material and balance the long heating/cooling time for each print. If you only print a few pieces each time, it is hard to convince to own a small nylon machine is cost-effective compared to outsourcing to other service business.
You know the HP MJP nylon is like $0.2-0.3/gram now for printing service charge?
