Various depending on finished metal work – example of sizes shown in Teacher Explanation.
Number of pieces:
2 per student
During this project, students have been using various techniques to cut, prepare, shape and join various materials. Students would have used 2D Design to create an image that would then be engraved onto Acrylic using the Laser Cutter. To complete the project the Acrylic will need a base to allow it to stand.
Students will be able to:
- Understand why they need to cover the mild steel
- Understand Tinkercad
- Learn 3D printing techniques
- Create and print in 3D STL models of their base.
Discussion of tools within Tinkercad and re-cap how to perform basic actions.
Discuss the size of the base needed to support the acrylic
Discuss how to transfer the file (STL) to Flash Forge Finder – individual basis when appropriate.
Re-cap the unit of work covering Permanent Greeting Card – workshop techniques.
Discuss with students the shape needed for the base to allow the acrylic to stand up – students will need to measure their acrylic to check the finished sizes. Discuss with students the purpose of adding the plastic – to finish off the product adding colour, and to support it. Discuss the use of Tinkercad and how to transfer the information to Flash Forge Finder – re-cap how to save an STL.
Step 1: Students to measure their acrylic in mm. Students will draw out the shape and record the measurements of their chosen base design.
Step 2: Students draw on prior knowledge of Tinkercad to draw out the base.
Step 3: Student to export to Flash Forge Finder and scale to ensure plastic fits around the metal
Step 5: Printing – each student to print their base exporting from Tinkercad to Flash Forge Finder.
Step 6: Students to attach plastic to acrylic.
Step 7: Students to photograph Permeant Greetings Card for production log
Step 8: Students to write about the process they have carried out in their production logs.
