Running cost

  • The tube is £250 for 1000 hours
  • The lens+mirrors are £150 for 250 hours
  • The power is (say) 1.2kW at £.2/kWh.
  • So 250/1000 + 150/250 + 1.2*.2 = £1.09/hour
  • The space also used a large chunk of funds to get the cutter, this needs to be recouped.

Therefore a recommended donation of £5 for each hour of use would be greatly appreciated.

Laser cutter money held in the the foundation bank account:
