The Caltech Library TechLab operates largely on the Caltech Honor Code.  By using our service, you agree to the following: 
This is Ernie - a simple two-wheeled robot created with 3D-printed parts, an Arduino microcontroller, an ultrasonic sensor and a pair of IR sensors. Made by one of our undergraduates, Ray Sun

  • I will not print any weapons or offensive material
  • I will not stop another user's job mid-print to start my own
  • I will not occupy more than one printer at a time, unless by special request
  • I will not use slicing settings that use unnecessary and excessive material and time (Printing large objects at 20 micron, printing large objects with 100% infill, etc.)
  • I will examine my sliced model carefully and pay attention to the start of the print job for first-layer issues
  • I will check the build plate is empty before starting my own print
  • I will contact techlab [at] when issues arise
  • I will exercise safety when handling hot or sharp objects
  • I will clean up after myself
  • I understand that I am free to explore the technology, but in the event the machines are operating at capacity, priority will be given to research and class-related projects (upon TechLab admin approval)
  • I understand that the Techlab cannot guarantee the availability of printers or the success of my print

Thank you for abiding to our terms and don't hesitate to contact us for any questions regarding usage and policy.
