3D 프린터를 구매하셨는데, 이제 뭐해야 하나요? 새로운 3D 프린터를 최대한 활용하세요

Congratulations on joining the exciting world of 3D printer ownership! When I purchased my first 3D printer nearly a decade ago I was so excited about all of the 3D models that would decorate my office. One of my first prints, a Shrek tissue box, printed for over 10 hours until I heard a now very familiar clicking noise from my printer. It had clogged and was now missing the top 20% of the print. You know the old saying When life gives you lemons… make a pencil holder. The incomplete Shrek head has served me well by both teaching me a lesson about how to deal with a clogged nozzle as well as holding all of my pencils and pens inside the holes made by the infill.

In my first months of 3D printing,  I learned the ropes with several fun models like Flexi-Rex(A flexible dinosaur), Cali-Cat(a calibration tool in the shape of a cat) and Benchy(a calibration boat) My biggest challenge and experience came in the the Spring of 2020 when, like many, I felt powerless when it came to the Covid-19 Pandemic and wanted to find a way to help. When I saw on the news that PPE, especially face shields, were in short supply I found my calling. I worked with a group of fellow teachers to bring the 3D printers sitting dormant in our local schools to our houses to create our own “printer farms” capable of printing in mass quantities these desperately needed supplies. With 10 3D printers running in my office and the help of several students, we 3D printed and donated over 3500 face shields to nurses and doctors in need throughout the United States. This experience truly taught me the power that a group of makers can have to change the world. 

Just type “clogged 3D printer nozzle” into YouTube and you will see 1000’s of helpful videos showing how to deal with this dilemma. The only problem is that these solutions are often dated, confusing or simply apply to a different 3D printer than the one you own. The purpose of this class is to provide for new young 3D printer owners a guide on how to handle both the challenges that 3D printers throw your way as well as provide some of my favorite projects that are sure to excite and inspire new 3D printer owners. 

While this is a FLEX class, I am here to serve as a mentor to new 3D printer owners as they begin their exciting journey. In addition to the 4 weeks of screencasts showing everything from setup to troubleshooting, students can message me on OutSchool at any time with questions. I will even be able to schedule a Live session on Zoom if students are in need of more in-person advice. Having someone to bounce ideas off of will lead to more confidence and success as students learn all about their new printer. 

This FLEX class will be useful to owners of a wide variety of 3D printer brands, but will use the printers I personally own for both lessons and specific guidance. I currently recommend the Ender 3 S1 or Ender 3 S1 Pro due to its more up to date technology like a direct drive extruder as well as the more modern sprite hotend. If you are looking to purchase your first 3D printer please free to message me any questions on Outschool and I will be glad to help work through all of the jargon.

Class Interaction Details
This class will go far beyond messaging and classroom posts. Students will be able to send in weekly videos and photos to share with both the teacher and their fellow classmates. We will organize these photos into a “Maker fair” for students to provide feedback and encourage each other as they learn this exciting craft. Each week will also include a “Maker’s Challenge” where students can use Tinkercad and their personal creativity to create and share their designs with the group.
