Take a T Make a T
Found a “T”? Now what?
Inspired by Georgia Tech’s long-standing tradition of “stealing the T,” the Take a T, Make a T project puts a fun, hands-on twist on campus culture. With many signs missing their T’s, The MILL has designed custom 3D-printed and laser-cut T’s that fit perfectly into these gaps. Each T features a QR code linking to The MILL’s website, inviting students to learn more about our make-and-measure space.
The challenge? Find a T, take it, and bring it to The MILL to claim a mystery prize! Once you “steal” a T, we encourage you to craft a replacement using our equipment, keeping the tradition alive while exploring materials science and engineering.
The Materials Innovation and Learning Laboratory (The MILL) is the first-ever undergraduate MakerSpace primarily dedicated to Materials Science and Engineering (MSE). The MILL provides a safe and relaxed discovery space to gain hands-on experience with common discipline techniques, including the characterization of materials’ chemistry and structure, the measurement of material properties, and materials processing. All Georgia Tech students, faculty, and staff have open access to learn about any of our equipment during our open hours:
(Mon – Fri ,9 am – 5 pm)
Our Main Lab is located in the J. Erskine Love Building, Room 176.
Types of “T”s
PETG
You Found a Common T!
This “T” is made of PETG, the most common “T” we put out. Don’t let the rarity fool you—it’s a workhorse material! With its toughness, flexibility, and heat resistance, PETG is a go-to for functional parts and outdoor projects.

PLA
You Found a Common T!
This “T” is made of PLA, another common “T” we put out. PLA is the a weaker version of PETG in terms of toughness, flexibility, and heat resistance. PLA is much cheaper than PETG which is why PLA is used to make prototypes or temporary designs, but they do still make for great fidget toy material!

ABS
You Found an Uncommon T!
This “T” is made of ABS, one of the uncommon “T” we put out. ABS compared to PLA and PETG is the best in terms of toughness, flexibility, and heat resistance. The material does have a caveat to its great properties in which ABS produces toxic gas when printed. If you want to use this material at the MILL, make sure to use the Prusa MK4’s and the Bambu 3d printers because they have ventilation!

TPU
You Found a Rare T!
This “T” is made of TPU, a rare “T” we put out. TPU is prone to deform easily when face with intense heat, but its lack of heat resistance is compensated by TPU’s flexibility. TPU is one of the few materials that can be bent without permanent deformation and has excellent impact strength. Despite this property, TPU is very hard to print needing the be used at very low speeds and precise settings for retraction. When using, make sure to never put it in the AMS of a Bambu as it will get stuck!
