This lesson is about learning a tool for making colored stickers. First, students should try out their own technique and think about what problems might arise when making colored stickers with the vinyl cutter. You will then receive a ruler template with which you can solve the same task more easily. They should find out how to use the template, write short instructions and discuss possible changes or improvements.
Vinyl Cutter, adhesive film (different colours), transfer film, laser cutted stencil rulers
At the end of the lesson, students should have acquired or improved the following skills:
1. Students can stick multi-colored stickers using a stencil
2. The students develop their own strategies for using stencils and templates
3. Students reflect on different ways to solve problems
4. Students improve their skills using the vinyl cutter
The students should have already gained experience with the vinyl cutter at the beginning of the lesson. This also includes having a good command of the program (e.g. silhouette studio).
It should be noted that the multi-colored stickers are not all that large. Around 5cm x 10cm is a good size. It has also proven to be a good idea for students to cut the transfer film on one arm of the stencil with a knife when applying the sticker parts. If the adhesive film is only fixed on one axis, it is easier to apply. Despite the template, the first results may not be perfect. This requires a lot of training. Once you understand it, the template works really well.
Development of the problem
The students are shown a multi-colored logo that is to be made as a sticker using the vinyl cutter. The students discuss which technical problems need to be solved. They mention aspects such as:
– Each color must be cut individually
– Align several adhesive films precisely with each other
– Accuracy when aligning and placing
Working in pairs, the students try to stick a given multi-colored graphic onto a sheet using the vinyl cutter
A given svg file should be cut out with the vinyl cutter and multi-colored applied to a sheet of paper. The students discuss different possible solutions and try them out. Possible ideas from students:
– The students try to manually align the individual colors on the sheet by eye.
– The students try to manually align the individual colors on the transfer film by eye and then transfer them to the sheet
– The students first transfer a single-color negative of the motif onto the transfer foil and manually fill the gaps with colored foil elements.
Students share how they can use a template and stencil to simplify and improve
The teacher shows an SVG file that, in addition to the multicolored motif, also contains alignment marker dots. A matching stencil ruler is also shown. Students are encouraged to think about how they could use these resources to solve their problem. Students make the multi-colored sticker a second time using the new resources.
The students compare the results and discuss advantages and disadvantages
The students discuss in small groups how they have used the new tools. They describe how they overcame difficulties and the benefits of working with the stencil rulers. They make suggestions on how to write instructions for working with the stencil. The students think about how the stencil could be improved. They make suggestions as to what type of multi-colored graphics the stencil can be usefully used for. The students discuss which multi-colored graphics and applications could reach its limits when using the stencil.
Finally, the students discuss in which areas of technology alignment templates
are used and under what conditions the use of stencils makes sense.
