You can check now. However it is not guaranteed that it will print in steel. There are some thin wires that need to be thicker than when printed in plastic. It might be worth a try, that would make a stunning piece! If it doesn't print, I think you can get your money back, but I usually keep it as shop credits when that happens.
Oh wow! Yes, it would be a stunning piece - but the price is even more stunning! 180 is a little too much at this time...I will perhaps have to consider the basic plastic option, which would still look good on my desk.
