How-To: 3D Printed Batarang: Part 2

Hey nerdy friends, I’m back with my prop building guide on how to create a 3D printed Batarang from the Batman: Arkham video game series. If you missed part one of my build, that just went through the steps on how to draw the prop on the 3d software. Today we will look at the 3D printing part of it. At Purdue University, the college is blessed that our library has a 3D printer for the students to use.

This is the first time that I had to use a 3D printer, so this is new territory for me. I first found out about this when studying one night in the Siegesmund Engineering Library in the Potter Engineering Center.  Did you know that every student at Purdue gets 75 grams of material a month? I didn’t until this project.

For this build, you need:

The Siegesmund Engineering Library has a great guide on printing out your project to the exact dimensions that the library requires. I recommend following them but I’ll lend you a few hints on working with this.


First, after saving your file as a “.stl” file, boot up the Cube printer application. From there, select your image of that file and start playing with your image. In the picture you see, my Batarang is loaded on the printer base. I figured I could fit the right side of the Batarang on the pad to save time because I would only have to make two trips to the library. You can use the ‘i’ button in Cube print to find your print time and how much material you will use. That last point is critical. Since you only get 75 grams, you have to make sure your print is under that because they will cut you off. If you can, print your project out a week before the end of the month. Why? The 75-gram material limit renews itself, therefore you are really getting 150 grams in a two week if you print one before and after the first week of a new month. That is what I have to do because I want both sides to be finished.

After making sure that your print is underweight and exactly right, save it to a USB drive. You will want to save it as a “.cube3” file, this makes it print on the 3D printer. Make sure you know the name of it because the library will ask you for it. Bring this to the Siegesmund Engineering Library on the first floor of the Potter Engineering Center. Fill out the sheet of paper with your name and the file name of the project on the USB. Due to increased demand on the 3D printer, the printing will take a week. So, give it time and work on other parts of your cosplay.  If you want, you might be able to view your object as it is printing in real time. This is a cool process to see how this whole process really works.


After your print is done, you will receive an email saying to pick up printed item. When you do, the library staff will give you back your USB and the finished printed object. Thanks to the Purdue library, we have just printed our item. You can’t just use it yet, now the cutting, sanding, and gluing come next. Stay tuned to the part 3 of our build on the Nerdy Nexus. Same bat-time, same bat-channel.
