Just Add Sharks Silvertail A0 Laser Cutter

Bristol Hackspace is privileged to have an enormous 1200mm by 900mm 80 Watt laser cutter.
The laser cutter is a fantastic tool that allows you to produce complex shapes from designs made in CAD. It's great for quick production of 2D designs and is one of the easier rapid prototyping machines to understand.

Usage

  • Any use of the laser must be in line with the Usage Agreement
  • There is a charge of £5.00/hour pro rata (0.0833 per minute) for laser cutting time

Inductions

All users MUST be inducted prior to using the laser. Please request an induction on the Google Group and familiarise yourself with the documentation prior to attending your induction.
