Building skills for the future with CNC routers and laser cutters

Across Aotearoa, schools are embracing advanced manufacturing technologies to inspire innovation, foster critical thinking, and better prepare students for the future. 

In 2017, the Technology learning area of The New Zealand Curriculum was revised to strengthen the positioning of Digital Technologies within the curriculum.

This change was designed to ensure that all learners can become digitally capable individuals – not just users of technology, but innovative creators. It reflects a broader national commitment to equipping students with the knowledge, skills, and confidence to design, develop, and deploy technologies that address real-world challenges.

At the heart of this approach are digital tools such as CNC routers and laser cutters, which are increasingly being integrated into schools across Aotearoa.

No longer exclusive to industry settings, CNC routers and laser cutters are becoming core features of school workshops, design studios, and makerspaces, offering students valuable hands-on learning experiences.

By integrating this equipment, schools are enabling inquiry-based learning and encouraging students to explore, experiment, and problem-solve. These tools bring together multiple disciplines and offer creative, technical, and practical applications across the curriculum.

CNC routing: Creating with precision

CNC (Computer Numerical Control) routing introduces students to the world of automated fabrication. With this technology, students use computer-aided design (CAD) software to create digital models that are then precisely cut into materials such as wood, plastic, foam, or aluminium. This process builds digital literacy while providing a solid understanding of materials, design thinking, and production workflows.

CNC routing allows students to explore concepts in geometry, physics, and engineering while producing items like signs, furniture components, scale models, and custom-designed parts. The process of planning, designing, and fabricating strengthens students’ understanding of cause and effect, accuracy, and spatial reasoning. It also enhances their capacity for iterative thinking, as they learn to assess, modify, and improve their designs based on feedback and performance.

Laser cutting: Engaging the imagination

Laser cutters are among the most versatile tools in a school setting. They allow students to cut, engrave, or etch designs into a wide range of materials, from acrylic and plywood to cardboard and leather. Laser cutting is widely used across subjects, including STEM, the arts, and design technology, as it supports both creative expression and functional design.

In a STEM setting, students might use laser cutting to create parts for robotics or construct engineering models. In visual arts and media studies, students may create intricate stencil designs, layered artworks, or display materials. In design and technology, laser cutting provides an efficient method to realise product concepts or architectural plans with professional precision.

The accuracy and speed of laser cutting make it an ideal tool for prototyping and production. It enables students to focus on problem-solving and iteration without being limited by traditional hand tools, allowing them to take their ideas further.

To learn more about how this technology can be implemented in school environments, School News spoke with Makerspace NZ Director and “Chief Do-er” Marcus Lund.

How have CNC routing and laser cutting transformed the way students engage with hands-on learning and creative problem-solving? 

CNC routing and laser cutting machines have significantly transformed hands-on learning and creative problem-solving for school-age students by introducing accessible, precise, and versatile tools that bridge digital design with physical creation. These technologies empower students to engage in STEM/STEAM education in a dynamic way, fostering skills like critical thinking, collaboration, and innovation. 

Digital fabrication technology can facilitate enhanced creativity and design thinking by allowing students to develop original ideas and bring them to life through iterative design processes. It promotes hands-on engagement with technology, giving learners practical experience with digital tools and materials in real-time. 

Through these experiences, students strengthen their problem-solving skills by addressing real-world challenges that require critical analysis, experimentation, and revision. The use of CNC routing and laser cutting also supports interdisciplinary learning, bridging subjects such as science, technology, engineering, the arts, and mathematics. Importantly, these tools help prepare students for future careers by building digital fluency and exposing them to technologies commonly used in design, engineering, and manufacturing industries.

Essentially, CNC routing and laser cutting machines have revolutionised STEAM education by making hands-on learning interactive, interdisciplinary, and future-focused – equipping students with the tools and mindset needed to tackle complex problems creatively.

What safety and accessibility considerations should schools prioritise when implementing this equipment? 

CNC Laser and CNC Router machines should always be purchased from reputable NZ- based suppliers who can provide machines with appropriate safety systems, user training and ongoing support and machine servicing. 

Machines sourced directly from overseas are often lacking in safety systems and may not conform to local safety standards, not to mention the lack of training and onsite service.

There are several important safety aspects to consider when implementing digital fabrication technology in schools. Machines should be equipped with emergency stop buttons (E-stops) and interlocks to ensure they can be safely shut down in the event of a malfunction or emergency. 

Appropriate dust collection systems or fume extraction and filtration must be installed, depending on the materials being used, to maintain a safe and healthy working environment. 

Comprehensive training for both staff and students is essential, with consideration given to age appropriateness and supervision requirements. Clear signage and restricted access to machine areas should be in place to prevent unauthorised or unsupervised use. 

Finally, both routine user maintenance and scheduled maintenance provided by qualified suppliers are necessary to ensure machines remain in safe, working order over time.

By prioritising these safety and accessibility considerations, schools can integrate CNC routers into their programs responsibly, fostering a safe and inclusive environment where all students can explore digital fabrication and creative problem-solving. 

Finally, what advice would you give to schools looking to invest in CNC or laser cutting tools for the first time?

Do your research! Speak with fellow tech teachers from around NZ – forums and Facebook groups can be really helpful for making these connections.

It’s also important to have open conversations with suppliers. Ask them what options they can offer to meet your school’s specific needs, and whether they can provide a comprehensive “turnkey” solution that includes delivery, installation, training, and ongoing support. 

Reputable suppliers will stand by their products and offer the post-sale service that helps ensure long-term success.
