In this STEAM maker project, students explore movable-type printing by designing and laser cutting reusable character blocks with LaserMaker. The lesson connects cultural history, poem selection, typography, mirrored text, engraving and cutting layers, printing plate design, ink application, paper transfer, and classroom presentation.

1. Lesson Overview

1.1 Project Goal

Students will learn the basic idea of movable-type printing, choose a short poem, count the required characters, design square character blocks in LaserMaker, mirror the text for printing, laser cut the type blocks and printing plate, arrange the poem, apply ink, and create a printed result.

2.1 What Students Will Learn

2.2 STEAM Skills Developed

2.3 Responsible Making

Students should operate the laser cutter only under teacher or lab supervisor guidance. Before processing, check the focal length, material placement, cutting layer, engraving layer, and layer order. During printing, keep ink, brushes, paper, and rollers organized so the workspace stays clean and safe.

3. Cultural Context: What Is Movable-Type Printing?

Movable-type printing is a printing method that uses individual reusable type blocks instead of copying text by hand or carving a full fixed page each time. In the source lesson, students discuss China’s four great inventions, Bi Sheng’s role in movable-type printing during the Northern Song Dynasty, and how individual type blocks can be selected, arranged, inked, printed, and reused.

For the classroom project, students use laser-cut wooden type blocks as a hands-on way to understand the process. The goal is not only to make a printed poem, but also to understand why reusable type can make printing more flexible.

4. Pre-Class Thinking Questions

Teachers can begin the lesson with short cultural and design questions. These prompts help students connect the printing project with history, language, and production logic.

5. Preparation Before Class

Before using LaserMaker, students should choose a short poem and plan the size of each type block. The source lesson suggests choosing a five-character or seven-character poem, counting the number of characters, and designing a square font block before building the full printing plate.

6. Lesson Procedure

6.1 Design the Character Blocks

Open LaserMaker and design one character block using the same general method as a single-character seal. The type block should be square so the characters can align neatly on the printing plate.

After duplicating the first character block, double-click the text in each square and change it to the correct character from the poem. Remove any extra text or engraving layers that are not needed for the final design.

6.2 Mirror the Characters and Set Parameters

Select all the character blocks and use Rotation > Horizontal Flip to mirror the design. This step is essential because the printed result is reversed from the engraved surface.

Set the cutting and engraving parameters. The source workflow uses 3 mm plywood, so the cutting parameter should match 3 mm material thickness. After setting parameters, check the layer order carefully before sending the file to the laser cutter.

6.3 Design the Printing Plate

Select all the character blocks and check their total size. In the source workflow, the total character layout is shown as 125 mm by 125 mm.

Create a new file or draw a square with the same size as the full character layout. In the source example, this layout square is 125 mm by 125 mm.

Draw a second square about 10 mm larger than the layout area and place it around the first square. This larger square becomes the outer border of the printing plate. In the source example, the outer border is shown as 135 mm by 135 mm.

Set the cutting parameter for the printing plate. Because the source lesson uses 3 mm plywood, the plate cutting parameter should also match 3 mm material thickness.

7. Laser Processing and Assembly

7.1 Machine Processing

Import the completed design files into the laser cutting machine for processing. Before starting, adjust the focal length to reduce the risk of incomplete cutting.

7.2 Assemble the Printing Plate

After cutting, align the outer frame with the edge of the plate and secure it with white latex glue or hot glue. Then arrange the finished character blocks on the plate in the order of the selected poem.

8. Movable-Type Printing Process

After the type blocks are arranged, students can use the finished type for printing. Prepare ink, an ink stone, a brush, rice paper, and a roller.

First, use the brush to apply ink evenly across each character block. Then lay the rice paper over the type and gently roll across the paper so the ink transfers evenly. Finally, slowly lift the paper to reveal the printed poem.

9.2 Teacher Suggestions

10. Reflection and Evaluation

10.1 Reflection Questions

10.2 Student and Peer Evaluation

Students can evaluate their own work and give peer feedback based on creativity, technical process, artistic effect, and collaboration.

11. Finished Project and Sharing

At the end of the lesson, students can present their printed poem, explain the type block design, describe how they arranged the characters, and discuss how they would improve ink coverage, alignment, or print clarity in the next version.

12. Extension Challenge

After finishing the basic poem print, students can design another printing plate with a short quote, class motto, personal message, or bilingual text. They can also compare different block sizes, character spacing, ink thickness, paper types, and rolling pressure to see how each factor affects print quality.

For a broader challenge, students can compare movable-type printing with block printing, stencil printing, screen printing, and modern digital printing, then explain which method is best for different classroom or design tasks.

13. Equipment Note for Teachers

This project is suitable for classroom laser cutters that support engraving and cutting of thin plywood for small maker and cultural design projects. For schools and beginner STEAM labs, projects like movable-type printing blocks, seal-style characters, printing plates, and beginner LaserMaker activities can be completed with a classroom laser cutter such as the Thunder Laser Bolt Series.

Teachers can choose the machine and material setup based on classroom space, student supervision needs, material thickness, project size, and ventilation setup. Students should always test settings, check focus, and follow the school’s laser safety rules before final cutting.
