3D designing & printing Xingming Yin (personal name seals)

Duration: 3 classes

I worked with Yue Tang and Yusi Gao, Class VIII Mandarin teachers at The Brearley School, on a Xingming Yin (personal name seals) project. Historically and currently, a yin is a seal or stamp used to “prove identity on documents, contracts, art, or similar items where authorship is considered important.”


Chinese seals


  • Sharpies
  • Tinkercad or Morphi
  • Inkpad
  • Paper

Yue and Yusi allotted three class periods for students to design a seal in Tinkercad, print their stamp, and try using the finished product. The steps involved are:


printed seals

  • Create a hand-drawn design.
  • Use Photoshop to isolate the ink.
  • Flip the image horizontally.
  • Export as JPG.
  • Convert JPG to SVG (with online converter.
  • Import SVG to Tinkercad.
  • Place SVG onto a box.
  • Slice and 3D print


Seals as tatoos

To view slides  shared with the Brearley girls to help them navigate the Photoshop and Tinkercad steps at their own pace and the slides from a presentation about this project presented at a NYCISTk6 meetup with other technology teachers from NYC independent schools go to Karen's blog.
