The Keller Center Makerspace is a new space for creativity, innovation, design, and curiosity in the Princeton campus community. Transitioned to an open access makerspace in November of 2021, the Keller Center Makerspace is growing and developing to be a space that fulfills the following mission, vision, and values for the space. 

Current Open Access Hours 

The last day of spring 2023 open access hours is May 5, 2023. 

Summer 2023 open access hours will be set early June.

Mission, Vision, & Values


The Keller Center Makerspace is an open-access makerspace for the entirety of Princeton University's community. The space provides access to a variety of maker equipment enabling users to explore the process of making, entrepreneurial ideas, innovative thinking, creative design, and taking ideas and making them into reality. 

The Makerspace hosts curricular and co-curricular programs along with an active calendar of making activities, talks, and events. 


As part of the Keller Center, Makerspace shares the Center's and Princeton University's vision of fostering a culture of design, innovation, making, and resilient practice for students to use their education, passion, and creativity to grow themselves.   

The Makerspace will serve as a space where the Princeton University community from all disciplines comes together to connect, make and design, work through ideas, and inspire ideas that make meaningful differences in a setting of personal practice.


Culture of Design, Practice, and Making 

  • We value the exploration of design, technology, curiosity, and passion through making things.

Inspiring Innovation & Collaboration 

  • We value the idea of connecting, sharing, and collaboration. We see the space as where a student's passion and pursuit can be infused together. To awaken a new sense of community.

Rewarding and Inclusive Frictionless Experience 

  • We value the inviting and inclusive space to prerogative a rewarding experience in trial & error and making. We aim to make a frictionless process for learning our technology and equipment.

Practiced Discipline 

  • Instead, we value the challenge of problem-solving within a set parameter of discipline and the practice of trial & error. Believing the rigor of practiced discipline nurtures innovation and embeds safety. 

Getting Started at the Makerspace 

The first thing before getting started at the Makerspace is completing the Machine Shop Online Training Module. This will give you the basic safety training of using our space. 

Then, there are few ways you can get ready and started at the Makerspace. 

  1. Drop in during our Open Access Hours and ask one of our staff members to help you get trained on our machines. 
  2. Email us to schedule a tour or a training for a specific machine.
  3. Use our Bookings system to reserve a training or project consultation. (Booking system in development. Will be deploying soon.) 

3D Printing Training 

If you are interested in learning about 3D printing and using our 3D printers, then enroll in the MakeNet Canvas and go through the 3D Printing training module. This training module was created by the MakeNet Makerspaces. Once you have completed the online portion of the training, then come to the Makerspace for the in-person training portion. After completing both parts of the training you will be able to use our 3D printers and the other MakeNet Makerspaces' 3D printers.

How much does it cost for materials? 

At the moment the Keller Makerspace provides the materials (3d printing filament, laser cutting materials, woodworking wood, etc). for “free”. 

There are some materials that are reserved for the courses happening in the Makerspace. Ask one of our Staff to help you identify which materials you can use. 

If you have a large project, please schedule a consultation with the Makerspace Manager.

The best way is to schedule a consultation with the Makerspace Manager, Castle Kim, or with one of the Graduate Student Educators at the Makerspace.

How do I get involved with the design and making community on Princeton Campus?
