Laser Cutting


  • In general, most acrylic sheets are 3mm thick, however always measure the thickness of the sheet you will use because the thickness varies widely
    • This dimension should help with drawings
  • The laser cutter cuts off approximately .07mm of extra plastic when cutting
    • For example, if I were to friction fit a piece of acrylic in another, I should make the width of the hole .14mm smaller than the desired width
