In an effort to provide more individuals the opportunity to access the resources of the Fabrication Lab at the end of the semester, additional limits are observed. These limits do not guarantee everyone access, so please be conscientious of your own and others’ needs and start making early.

Between Wednesday, April 16, 2025, and Monday, May 5, 2025, inclusive, the following changes to our “normal” limits will be observed:

Note: For the first time, we will be observing a limit to the total number of hours the CNC router may be booked by an individual.

Zünd Cutter

• Daily limit of 1 hour of walk-up usage
• Daily limit of 2 hours of reserved time
• Total limit of 3 hours of reserved time between April 16th and May 5th, inclusive
• Additional time may be reserved on your behalf, at the discretion and availability of Lab Staff and Technical Assistants, by submitting a job to the FabJob app for review
• Repeat (3) failure to make use of reserved time (recorded as “no show”) or replacement of approved files with others when appearing for reserved time will result in the loss of ability to reserve time in the future
  • Uploading “placeholder” files at the time of making an equipment reservation may be considered a “no show”
  • Failure to be present within the first 10 minutes of reserved time will forfeit the remainder of the reservation and may be considered a “no show”
• Some methods and materials, including all use of the router attachment, require time be reserved by submitting a job to the FabJob app for review, and will not be accommodated through walk-up usage

See the Zünd Policies page for more information.

Laser Cutter

Note: Laser Cutters are now booked in 30-minute slots, rather than full-hour slots, to better accommodate user needs.

• Daily limit of 1 hour of walk-up usage
• Daily limit of 2 hours of reserved time
• “Lina” is designated as walk-up machine, but it also serves as a back-up device should any of the reserved laser cutters become unavailable
• Failure to be present at a reserved laser cutter within the first 10 minutes of the reserved block of time will forfeit the remainder of the reserved time

3D Printers (Dremel)

• May not send prints requiring more than 48 hours of build time
• May not “hold” printers by leaving build plate and/or filament sitting in the device; TAs may remove build plates and filament if the printer is not actively printing
• May not send consecutive prints on the same machine
• May not use more than one printer at a time
• May not send prints on behalf of another individual
• May not send prints under another individual’s account
• May not remove prints belonging to another individual
• Only PLA filament from one of five approved brands may be used:
  • Dremel
  • Hatchbox
  • Overture
  • PollyTerra
  • Bambu
• PLA filament that contains additives must be approved for use in advance. Submit an SDS to [email protected] to start the approval process. For more information, see PLA Filament.
• Failure to observe these or other relevant policies will result in suspension of access to the Dremel 3D printers.

CNC Router

• Total limit of 8 hours of reserved time between April 16th and May 5th, inclusive
• Must prepare MasterCAM file following online tutorial and using a provided template file
• All files must be submitted to the FabJob app for review and approval by Lab staff before machine time may be reserved; files will be reviewed in the order they are received
• Individuals are advised to allow at least 5 full days between submitting a file and reserving equipment time; pay attention to the queue via the FabJob App as machine time is often booked a full week in advance
• Users must be present for the full amount of reserved machine time
• At the discretion of Lab Staff, settings in the submitted files may be modified to optimize to allow limited machine time to be shared by more individuals
