3D Printing

CIRT will print 3D models for faculty with our Makerbot Replicator 2 3D printer. We print with Polylatic Acid (PLA) filament. It’s a plant based bioplastic that is non-toxic and biodegradable. The Makerbot Replicator 2 is an additive or Fused Deposition Modeling (FDM) 3D printer ( also know as FFF or Fused Filament Fabrication in the open source community). This means, it adds PLA filament layer by layer on a build plate until an object is formed. Filament is fed through a heated nozzle which melts the PLA and slowly forms the object. If you can imagined a highly sophisticated & automated glue gun, that is basically what an additive printer is.

CIRT staff are happy to meet with you to discuss your 3D printing project. Please email us at or give us a call at 904-620-3927 to create an appointment.  You can also stop by anytime during our lab hours to see the printer.



The Makerbot Replicator 2 has a print volume of 10” long, by 5” wide, by 5” tall. It may be possible to print larger object in pieces, or several smaller objects at one time.

File formats

Printable file formats include .STL and .OBJ. If you have an object in another format we may be able to convert it into a printable format.

Submitting Files to Print

Files may be submitted in person or digitally. You can also use AirDropper (passphrase: cirtunf) to send files over 15MB or e-mail if less than 15 MB. 

Printing Time

Objects can usually be printed in 4 business days. However, the time it takes to print an object varies depending on several factors including, size, fill, complexity, and number of requests in the queue.
