Description

Intended for makerspace educators and interested makers, this course provides an overview of the safe use and maintenance of laser cutter machines. Students design and produce projects on the laser cutter, using a variety of materials (cardboard, paper, wood, acrylic, stone, glass, fabric) and serving a variety of functions (flatpack assembly, art, display, engineering solutions). Advanced topics include rotary tools, filtration methods, machine maintenance, and bed installment/changes. Special emphasis will be placed on reinforcing design thinking concepts and the development of laser cutter makerspace projects to meet the needs of a variety of users.

Course Objectives

The student will be able to:

  1. Identify the major parts and functions of a laser cutter and explain the role of each part in the machine's operation.
  2. Correctly determine which settings to use, including power, speed, and z-axis adjustments, in order to cut and/or engrave a variety of material types.
  3. Identify and describe the properties of materials that cannot be cut and materials that can cause risk or hazards, and practice safety protocols to mitigate risk and eliminate hazards.
  4. Perform machine cleaning and maintenance routines to ensure ongoing machine performance and safety.
  5. Design and produce engravings using a variety of materials, correctly selecting the appropriate settings for the design and the material.
  6. Design and produce three-dimensional objects by cutting and assembling flat materials.
  7. Engrave designs on rounded objects using the rotary tool.
