Lasercutting Process

Overview

In this ninth lesson of Crafting Cultural Connections: Lasercut Jewellery, students move from digital design to supervised manufacture. They will prepare the lasercutter, follow safety procedures, cut their jewellery pieces accurately, and evaluate the quality of the resulting outcome before the final finishing lesson.

Learning intentions

• We are learning to operate a lasercutter safely under supervision.
• We are learning to apply a digital design accurately to a selected material.
• We are learning to check a manufactured outcome against its specifications.
• We are learning to respond respectfully to cultural meaning and design ownership.

Success criteria

• I can cut my jewellery pieces accurately according to my specifications.
• I can demonstrate safe practices when using the lasercutter.
• I can identify and respond appropriately to a cutting problem.
• I can explain whether my outcome meets its intended purpose and cultural design brief.

Curriculum links

• Technology — Technological Practice: planning and managing the manufacture of a technological outcome.
• Technology — Technological Practice: evaluating an outcome against its specifications and intended purpose.
• Technology — Technological Knowledge: understanding how materials and tools are selected and used to create a functional outcome.
• The competencies of managing self, thinking, participating and contributing, and relating to others are developed through safe teamwork and peer support.

Lesson structure (60 minutes)

1. 0–7 min · Reconnect and hook. Teacher displays the manufacturing sequence in the introduction and safety slides and asks, “What could go wrong if a small safety step is skipped?” Students review their jewellery specifications, identify one accuracy requirement, and share one possible hazard with a partner.

2. 7–17 min · Safety briefing and demonstration. Teacher demonstrates the approved start-up and cutting procedure: checking the material, ventilation and focus; securing the bed; confirming the file, scale and power/speed settings; using the lid and emergency stop; and waiting for fumes or flames to clear before opening. Students complete a verbal safety check using the lasercutting preparation and safety checklist and signal when they are ready to operate under supervision. Emphasise that only the teacher starts the machine and that students must never bypass guards, place hands inside, or leave the machine unattended.

3. 17–23 min · Job allocation and final file check. Teacher organises five groups of five and assigns each student a supervised cutting slot, with one operator and designated observers at the machine. Students check their digital file against the specification: dimensions, shape, holes, orientation, material and quantity. Each student obtains teacher approval before cutting; unfinished or unsafe files are returned for correction.

4. 23–48 min · Supervised manufacture. Teacher calls students to the machine in rotation, confirms settings and supervises every cut. Students wear required protective equipment, observe from the marked safe position, monitor the cut without touching the machine, and record the result on the worksheet. While waiting, students inspect their drawings or prepare a short quality check rather than crowding the machine. Students may support peers by explaining the checklist, but only the assigned operator handles their own approved task.

5. 48–55 min · Quality control and troubleshooting. Teacher prompts students to compare each piece with the specification and models safe responses to common issues such as incomplete cuts, unwanted scorching, incorrect scale or misplaced holes. Students inspect edges and dimensions, record “meets”, “nearly meets” or “does not yet meet”, and identify one adjustment for the final lesson. Any failed cut is isolated and reported; students do not restart the machine or alter settings independently.

6. 55–60 min · Plenary and exit reflection. Teacher returns to the plenary and reflection slides and facilitates a quick review: “Which safety action protected people, equipment or materials?” Students complete the final section of the lasercutting preparation and safety checklist by recording one successful technique, one safety practice, and one improvement for finishing. Collect worksheets and store labelled pieces safely.

Resources

• Teacher-approved lasercutter with extraction or ventilation system
• Computer with approved jewellery design files and manufacturer software
• Suitable jewellery materials, labelled with student names
• Required personal protective equipment and machine safety signage
• the lasercutting introduction, safety, workflow and plenary deck
• the lasercutting preparation and safety checklist
• Measuring tools, pencils and storage containers
• Emergency stop and first-aid procedures accessible to the teacher

Assessment

• Observe each student using the safety routine: appropriate position, protective equipment, no unsafe contact, and prompt reporting of problems.
• Check the approved file and finished piece against dimensions, shape, holes, material and quantity in the student specification.
• Use the completed worksheet and exit reflection to assess understanding of safe operation, accuracy and next steps. Record students requiring additional support before the final lesson.

Differentiation

• Provide a graduated role system: observer, checklist partner, supervised operator, and independent file checker. Students progress when they demonstrate confidence and safe behaviour.
• Support students with a visual step-by-step checklist, pre-checked files, paired verbal rehearsal, reduced-complexity cuts, and teacher support for measuring or file preparation. Allow students to explain responses orally where writing is a barrier.
• Provide EAL learners with labelled photographs, demonstrations, gesture-supported instructions and key words such as focus, ventilation, scale, specification and emergency stop.
• Challenge advanced learners to justify a setting choice using material behaviour and design requirements, lead a peer through the checklist, and troubleshoot a simulated fault without touching the machine or changing settings without permission.

Extension

• Students who finish safely may experiment with unique finishing techniques post-cutting, such as testing different sanding patterns or surface treatments on an offcut first. They record the technique, predicted effect and whether it suits the jewellery’s cultural design and intended user.
