*The L3 CNC Shop will temporarily be closed on Sundays*

General Info

The CNC/Machine Shop at 2 West 13th Street (see map) supports both digital and manual machining with the following equipment:

• 4 Desktop ShopBots
• A 4’x8′ ShopBot Alpha with tool changer
• A Haas Super Mini Mill with 4th axis attachment
• 2 Roland MDX-40A bench top CNC mills with rotary attachments
• 2 Manual Vertical Mills
• 3 Manual Machining Lathes

Model production in the CNC/Machine Shop

With proper training and supervision, students can use this equipment to fabricate projects to high levels of precision out of foams, wood products, plastics, waxes, and metals.

The CNC/Machine Shop also has a Casting and Epoxy Room (more info below) for plastic casting and rubber mold making, and there is a spray booth and airbrush room down the hallway.  These facilities have ventilation for working with certain materials, but students must still use appropriate Personal Protective Equipment and only work with materials from the Approved Materials List.

Safety Orientations

Students must attend a short safety orientation before they can use this shop. Once completed, students will receive a sticker for their ID. This is separate from the Wood Shop or Metal Shop safety orientations.

We’re including the safety orientation at the beginning of all CNC tutorials for the time being.  If you only need access to the Casting Room, please check in with the Technician ahead of time if you have not had a previous orientation.  We can often give a quick safety orientation if the shop is not busy.

CNC Tutorials

We provide hands-on tutorials for the CNC equipment. Students must attend one of the tutorials and then complete a short assignment before they are cleared to use the CNC equipment in the CNC/Machine Shop (the CNC Shop in the 25 East 13th St. building has a drop off service for students who do not want to run their own files). Tutorials last about 2 hours and take place in the CNC Shop on the 3rd floor of the 2 W 13th St. building.  The assignment after the tutorial will take one to two hours to complete, and can be done anytime in the week following the tutorial.

Click the “Mandatory Orientation Sign-Up” button at the top of the page to reserve a spot at one of the CNC Tutorials.

If faculty members plan on assigning CNC specific projects, please reach out to Nathan Carter to coordinate.
