A Comprehensive Tutorial on Using 3D Printing Pens in Education
In recent years, 3D printing has become an increasingly popular tool in education. It provides a unique way for students to learn about design, engineering, and various STEM subjects by allowing them to create physical models of their ideas.
What is a 3D Printing Pen?
A 3D printing pen is essentially a handheld device that melts and extrudes plastic filament, allowing users to “draw” in three dimensions. These pens are typically used with PLA or ABS plastic, which can be heated up to a high temperature so it flows easily from the nozzle of the pen.
Why Use 3D Printing Pens in Education?
There are numerous benefits to incorporating 3D printing pens into educational settings. Firstly, they provide a hands-on approach to learning, allowing students to engage with the subject matter in a tangible way. This can help to spark creativity and encourage problem-solving skills.
Secondly, using a 3D printing pen requires an understanding of various STEM concepts, such as geometry, physics, and engineering principles. By engaging with these ideas through the creative process of 3D modeling, students can gain a deeper appreciation for these subjects.
How to Use a 3D Printing Pen in Education
1. Choose the Right Materials
Before beginning any project with a 3D printing pen, it’s essential to select the appropriate plastic filament. PLA (polylactic acid) is a popular choice for educational settings due to its biodegradable nature and relatively low melting point.
2. Develop a Design
Before starting to draw in 3D, it’s crucial to have a design or plan in mind. Students can use computer-aided design (CAD) software to create detailed blueprints for their projects, which can then be printed out and used as a guide while using the 3D printing pen.
3. Practice Safe Use
As with any tool that involves heat, safety is paramount when using a 3D printing pen. It’s essential to supervise students carefully and ensure they understand how to handle the device safely. Plastic filament can reach extremely high temperatures (around 240-265°C), so it’s crucial to wear protective gloves and goggles while using the pen.
4. Start Drawing in 3D
Once students have selected their materials, developed a design, and are properly equipped for safety, they can begin drawing with the 3D printing pen. The process is similar to writing or drawing, but instead of creating lines on paper, students create solid objects in three dimensions.
Applications and Examples
There are numerous ways that educators can incorporate 3D printing pens into their lesson plans. Here are just a few examples:
- Geometry: Students can use a 3D printing pen to create physical models of various geometric shapes and structures, helping them to better understand spatial relationships and properties.
- Biology: By creating 3D models of biological structures like cells or molecules, students can gain a deeper understanding of complex anatomical and molecular concepts.
- Engineering: In engineering classes, students can use a 3D printing pen to design and build functional prototypes, such as bridges or gears, which they can then test and analyze for strength and efficiency.
In short, incorporating 3D printing pens into educational settings offers countless opportunities for hands-on learning and creative exploration. As the technology continues to advance, it’s likely that we’ll see even more innovative applications of these devices in classrooms around the world.
