How LASER systems contribute to STE(A)M learning in schools

Future workers will spend less time on routine tasks and more using technology. Advancement in technology will continue to replace manual tasks, allowing more time for creative thinking and problem solving.

 How are kids preparing for this digital and process automated world?

Curriculum now includes development of skills in STE(A)M (Science, Technology, Engineering, Art and Mathematics) to engage students. Rather than just content and assessment, STEAM focuses more on outcomes and what students will gain from the learning experience. This type of learning adds more meaning to their studies as it is dealing with real-world problems. This curriculum will better prepare students for future jobs, with real-life experience with advanced technology.

 Why a laser cutter/engraver?

Laser cutting and engraving technology has an integral part in the manufacturing sector, among other industries, and is continuing to evolve rapidly. Sophisticated, multi-axis robotic and cartesian laser cutters are proof of how far this has come. This is one reason why laser cutters/engravers are emerging as such important technology right across STEAM based curriculum.

 What projects and subject areas do laser systems cater for?

Almost any design, technology or STEAM project can have an element cut and/or engraved on the laser, whether it be prototyping, electronics, woodwork, textiles, art, sculptures, décor or scientific modelling. It doesn’t mean that the whole project must be focused around use of the laser system, but it teaches students the process of applying a new technology. In addition, these systems can be used by the school administration to save money by engraving awards, trophies and any signage required.

What are some materials the laser system can work with?

• Acrylic
• Timber
• Plywood & MDF
• Leather
• Textiles
• Glass
• 2 ply & traffolite
• Rubber
• Cardboard & paper

What are some of the core skills students will develop using the laser system?

There are three key core skills developed throughout the design phase and use of the laser cutter/engraver;

Design – Involves the critical inventive thinking, creativity, use of human-centered design processes and visual-spatial skills to create, design and draw a project for laser cutting and assembly. In the case of designing a model for assembly, precision and accurate measurements are needed in the drawing to ensure everything will fit together once cut.

Laser operation – Learn the technology and machinery principles involved around operating such a system. An understanding of principles around safety, how the laser works, sustainability and use of material, as well as understanding the implications of their design.

Post laser processing – Depending on the project, this may involve hands-on assembly work, fitting together of an inlay, applying a finishing coat to the timber, stitching together of the textile or whatever the project may entail.

 How does use of laser systems contribute to enterprise/entrepreneurial curriculum?

Laser cutting/engraving partners well with enterprise as it requires critical and analytical thinking to develop a solution that fulfils a need. Working through the “user-centered design process”, students identify a need, research the market and develop their idea with prototypes. This entire process reflects what any aspiring entrepreneur will have to work through to be a success in the real-world. The remarkable thing about laser cutter/engravers, is that these machines cut and engrave to a quality that matches that offered by the commercial sector, making their products perfectly saleable in the real-world. 

Are laser systems difficult and daunting to use?

No, these systems are very easy-to-use once adequate training has been provided. A simple Windows print driver is used to set parameters and send your drawing to the laser. There is no confusing additional software. The use of this technology is ideal for breaking failure paralysis we so often see in students of today. In fact, failure is a critical part of STEAM. For example, a student may set an insufficient power parameter into the laser and result in a partially cut job. This doesn’t matter, let’s adjust the parameters and try again. This continual ‘trial and error’ means students are leveraging failure as a natural part of the learning process.

Laser cutting/engraving systems provide scope for enormous creativity and innovative design. Incorporating a laser system into your STEAM teaching will contribute to the development of students into the creators, inventors and thinkers of the future. They will develop from continually making, tinkering, fixing and improving. It’s these students who will go develop and push the boundaries of technology and be tomorrows change-makers.
