Introduction: Tetromino Tiling Puzzle of Dot Matrix Display

By Let's dfab!
About: I am interested in designing something curious but functional. Please take a look at my summary page, https://shiura.com/dfab/index-en.html

A tetromino tiling puzzle that can show all ASCII characters.

  • Fill the 8x8 board with 16 tetrominoes.
  • Each tetromino has 1 ~ 3 ON-pixels on a single side. (the all pixels on the other side are OFF)
  • Surprisingly, it can show all 95 ASCII characters by arranging the pieces.

Supplies

You can print this puzzle with common consumer 3D printers.

Step 1: 3D Print

To give a different color to the pixels, the piece should be printed out with three layers. Please use "Pause at Height" function of your slicer software.

  • Piece : Change the materials twice, at h = 1.0mm and 3.0mm
  • Board : Change the materials once, at h = 0.8mm


Step 2: Enjoy!

  • Typeface is specified as shown above. the other typefaces are not always possible.
  • I confirmed that there is at least one solution for each character using solver program.
  • PDFs of goals and solutions are supplied.
