What’s a MakerBot?

MakerBot Replicator with Some Prints

Pictured here is the MakerBot Replicator, a personal, desktop-sized 3D printer. Users are able to design a 3D object on their computer, or download an existing model from Thingiverse.com. Once you have the model, you simply send it to the printer via USB or SD card, and the Replicator will go into action, creating an actual 3D object. Through a process called additive manufacturing, layers as thin as .2mm are piled on top of each other one at a time until the object is completed. With the new Replicator model, dualstrution (extrusion of two different plastics during the same print) is now possible, enabling prints such as the globe on top of the bot to the right.

How do I fit in?

I fill many roles at MakerBot (as most employees of a start-up do), but my main role involves designing improved electronics for the bot. Specifically, I was responsible for designing an all-new electronics platform for the MakerBot Replicator. MakerBot’s previous two 3D Printers, the Cupcake and the Thing-O-Matic, implement an electronics system derived from the popular RepRap open source 3D printer project. While this got the job done, it required each bot to house as many as nine separate circuit boards plus a computer ATX power supply. For the Replicator, I designed the “MightyBoard” (shown above), a new single-board platform capable of controlling the whole machine (even the dual-extruder version) with ease. Since MakerBot is totally open-source, you can check out my handiwork first hand:

Some of my other roles at MakerBot include programming firmware, shooting timelapse videos, building programming rigs for the production folks, testing the shiny new technology (like the MK-7 Extruder), and helping with hiring new members of the R&D Team.

How did I end up working for MakerBot?

In the spring of 2011 I was selected to be one of twelve Cornell University Kessler Fellows. Kessler Fellows are engineering students who possess a unique passion for entrepreneurship, leadership, and technology. Each Kessler Fellow pursues a summer fellowship at a technology startup, with their salary paid by Cornell’s fellowship fund. For my fellowship, I worked at MakerBot Industries, under Co-Founder and Chief Technology Officer, Adam Mayer. After the completion of my fellowship, I’ve continued to consult for MakerBot remotely, and I go work at their Brooklyn headquarters whenever I find the time (usually during breaks from school). You can read Adam’s recommendation of my work, here.

Do I have a MakerBot?

Of course! I own a MakerBot Thing-O-Matic, and I’ll be the proud owner of a MakerBot Replicator very soon. Check out a timelapse video of me building my Thing-O-Matic below. You can also visit my Thingiverse page to see some things that I have designed and printed.
