Our February Hacker of the Month, Garrett Durland, initially hails from Denver, Colorado and presently resides in Oak Ridge, Tennessee. Garrett’s background is in Mechanical Engineering for a variety of corporations. “I spent 2006 to 2015 working as a Steam and Gasoline Turbine Engineer within the energy technology trade. I labored for GE, Toshiba, and Xcel Power. As an on-site touring engineer, my duties included planning and supervising and routine and emergency upkeep of enormous rotating equipment. Then I moved to Oak Ridge to simply accept a job at Oak Ridge Nationwide Lab (ORNL) on the Spallation Neutron Supply (SNS). I labored within the Central Cooling Methods group from 2015 to 2018. There I used to be a management room operator and the subject material professional for among the subsystems of the accelerator.”
He was first motivated to get into 3D printing by a good friend after he discovered that Garrett had been wanting into quite a few articles on Hackaday and Reddit in regards to the topic. He then went out and bought his first 3D printer, a Monoprice Maker Choose, and was rapidly bitten by the 3D printing bug again in November of 2015.

Garrett began modeling his personal creations in TinkerCad, which he nonetheless makes use of to make a number of designs for his Etsy store. He’s presently bettering his abilities in Fusion 360 and OpenSCAD, and he makes use of Meshmixer to assist him sculpt, hole his prints, and cut back the triangle counts on his fashions. He makes use of Cura and Simplify3D to slice his prints.
Quickly after buying his first 3D printer, he was given a non-working Prusa Mendel IT2 clone, which he repaired himself, after which went on to construct three extra 3D printers! He primarily makes use of these printers to provide gadgets for his Etsy store, Sassy Centaur. His store primarily consists of gender-neutral toilet indicators which might be infused with mythological and imaginary creatures. Garrett explains that “Gender-neutral toilet indicators make all people much less nervous about utilizing a public toilet. Hopefully, the humor within the indicators will even ship the message that it does not likely matter which toilet individuals select to make use of.”
Garrett primarily makes use of PLA for his gender-neutral toilet indicators, PETG for elements that require a little bit extra power, and carbon-fiber PETG for extra demanding functions and prototypes.

Garrett’s indicators turned extraordinarily well-liked, and after 18 months of constant development, he was capable of transfer on from his full-time mechanical engineering job into producing gadgets for his Etsy store as a occupation. After this transfer, Garrett was capable of create much more signal designs, in addition to supply extra choices for personalisation that will not have been attainable whereas working.
However Garrett hasn’t stopped there along with his curiosity in making and creating. Along with his new label as a Inventive Technologist, he has accomplished work for a biomedical imaging firm designing and fabricating a non-magnetic holder for considered one of their scanning devices from carbon-fiber PETG. “The half that I designed, printed, and delivered will assist the corporate calibrate and full reference scans with MRI-type machines.”

Creating 3D printed gadgets then led him to develop his materials choice and he quickly began to manufacture 3D printed molds for concrete planters. “In 2019 previous to the clay printer buy, I made 25+ concrete planter pots of various sizes and styles. With a three-part concrete planter mould, I used to be restricted by the construct quantity of my printer, so I went large and made a 3D printed, 13-part mould, with the thirteenth half being a versatile ice cream tub that I rescued from the trash.”

“I used to be capable of make eight giant concrete planters, however each took lots of prep work, and among the mould sections that had been printed with PLA are beginning to crack. If I did it once more, I might print the mould in PETG, and alter the design to beef up the areas that I discovered to be cracking most frequently. To promote giant concrete merchandise like planters, will probably be more cost effective for me to print them on a concrete printer, quite than utilizing 3D printed molds.”
Quickly after he backed a Kickstarter marketing campaign for a ceramic 3D printer, the Cerambot. The Cerambot permits customers to create objects from a viscous clay combination that comes out of the extruder in a lot the identical approach melted plastics are extruded from a 3D printer. “To date, I’ve used low fireplace clay for printing ceramic fashions, however I want to experiment with porcelain.”

The foremost distinction in 3D printing with clay is the post-processing; these objects must be fired in a kiln to change into sturdy pottery or ceramic items. With the mortgage of a kiln from a good friend, Garrett has been experimenting with varied clay mixtures for his Cerambot and might be including these creations to his Etsy store quickly.
His curiosity within the Cerambot and his concrete pots ultimately led him to a fair greater challenge; 3D printed properties. “Watching the clay because it printed on the Cerambot with a 2mm nozzle had me imagining greater creations and asking, ‘What may I create if I had a concrete printer with a 25mm nozzle?’”
Extra pots created on the Cerambot
To this finish, Garrett has partnered with Jessie Hawkins, proprietor of Strong Engineering in Knoxville, Tennessee to design and fabricate a full-scale, concrete 3D printer to be used in creating properties.
“I am hoping that giant scale concrete printers for architectural functions catch on. I am wanting ahead to the 3D printing group sharing greatest practices and how-to directions for reasonably priced printer builds of this scale. I am additionally hoping new constructing codes and rules might be tailored to make the allowing course of smoother. Ultimately, I might like to be on the group that designs and prints a group of concrete homes.” Understanding the fundamentals along with his house ceramic 3D printer has result in many insights that might be helpful in large-scale functions like 3D printed properties.

As well as, Garrett likes to share what he has discovered with others. “I’m presently growing some lessons and workshops to be held in Oak Ridge. In 2018, I taught a circuit prototyping class, the Atari Punk Console class, at Knox Makers in Knoxville. I might be educating this class once more, and likewise a number of 3D printing lessons the place members can have their mannequin printed proper in entrance of them. I will supply lessons in CAD modeling and slicing 3D printer operation, constructing a 3D printer, printing with clay, and maybe some lessons that develop soldering abilities.”
He additionally hopes that sooner or later, 3D printing is extra accessible to most people, not simply these going to varsities or establishments. “I feel each metropolis’s library ought to have some 3D printers to allow them to supply primary print companies to members, maintain educational workshops and provides demonstrations.”
We’re excited to see much more from Garrett sooner or later, in all of his many endeavors – particularly within the 3D printed properties trade. In case you’re serious about buying any of Garrett’s gender-neutral toilet indicators, or quickly to be accessible 3D printed ceramics, you’ll find them in his Etsy store right here:
