What did you pay for your equipment?

This is a critical piece. I have been 3D printing for profit for a little over 2 years now and I will tell you that all of your equipment can be depreciated as office equipment. So lets look specifically at the depreciation schedule for various business-related equipment:

    2. Municipal sewers other than property placed in service under a binding contract in effect at all times since June 9, 1996.


You will notice that mining equipment falls into the 5 year category. That means you can spread the cost over 5 years to offset mining gains. Again your CPA can further explain this.
