How 3D Printing Works
Stage I : create a 3 D model
Stage II: G-code (NC Program) generation in slicing software
Stage III: Print in 3D with 3D printer
Raw Material: Raw material comes in the form of spools of filaments. Filaments can be of any material like PLA, ABS, PLA+, woodfill, PETG etc
The type of 3D printer most often found in classrooms is called an FDM (Fused Deposition Modeling) machine
Here are just a few examples of how schools and students can use a 3D printer in the classroom:
· - History students can print out historical artifacts to examine
· - Graphic Design students can print out 3D versions of their artwork
· - Geography students can print out topography, demographic, or population maps
· - Chemistry students can print out 3D models of molecules
· - Biology students can print out cells, viruses, organs, and other biological artifacts
· - Math students can print out 3D models of problems to solve
These are some of the ways 3D printing technology is bridging the gap between the physical and the digital worlds - find what you need on the screen, then print it into existence.
Benefits of 3D Printing in Education
Practical Hands-On Approach: 3D printing in academics helps transform students being passive consumers to active creators. Current system relies heavily on theoretical learning and very little on real-world deployment of knowledge. Having access to 3D printing technology at grass root level allows more students to adopt a practical hand-on approach.
Creates Excitement – 3D printing offers students the ability to experience their projects from the model stage to actual creation of the model. This creates both excitement and a better understanding of the design process as they gain hands-on experience it from conception to creation. The individual features are seen more clearly as the student builds the project layer by layer. Excitement also stems from the ability to explore details in reality, not just on a screen or in a textbook. 3D printing also brings the world of theory to the physical world where students can see and touch, opening up new possibilities for learning and activities.
· Complements the Curriculum – No matter what curriculum is being used, 3D printing can help students and teachers work better. 3D printing elevates students from being passive consumers of information on a screen with no thought given to productivity. Unlike conventional classrooms where students are easily bored, they become active and engaged participants through the conception, design, and execution of their projects and interacting with the 3D printer and the teacher.
· Gives Access to Knowledge Previously Unavailable – Because most 3D printers are pre-assembled and plug and play, it is a fun cutting-edge technology for students to learn. Students learn that it is perfectly acceptable to fail on the first try and then try again in order to improve. As students begin to understand that failure is part of the process, they become less afraid to attempt and execute new and different ideas in life. This builds students’ confidence and teachers enjoy the results of having self-motivated, self-confident students.
· Opens New Possibilities for Learning – An affordable 3D printer opens up unlimited learning opportunities for students. 3D printing provides students with opportunities to experiment with ideas, expanding and growing their creativity. It is not easy to have young students figure things out without the benefit of visualization. A visual learning environment improves their understanding of the world, being able to touch and see their projects. 3D printers open up new opportunities for presenting information to young students in an economical and efficient manner.
Future of 3D Printing in Education
3D Printing is going to have a profound impact on all of us, whether you consider yourself a designer or not. In future, there will be 3D Printers which can print a three dimensional structure out of a living cell. Any complex structure can be created like a blood vessel or skin tissue. The whole organ can be built with the 3D Printers and that too with your own genetic cells, so you won’t have to find the donor of the organs anymore.
Japan researchers are taking data from the sonogram so that they can actually scan a pregnant woman’s belly & thereby 3d print the figure of her torso. How interesting would it be to determine what your baby looks like when it enters the world?
How schools get funded for 3d printing lab:
In an effort to encourage innovation and promote scientific temper, Niti Aayog as part of its Atal Innovation Mission (AIM) will provide ₹ 10 crore to 100 new incubators and ₹ 20 lakh to 500 tinkering labs in schools, Niti Aayog CEO Amitabh Kant said in a live chat on Monday.
Niti Aayog has invited applications from eligible schools, organisations and individuals to apply for the three major schemes under Atal Innovation Mission including establishing tinkering laboratories in schools, establishing new incubation centres and scaling-up established incubation centres.
