3D printing is an additive manufacturing procedure that makes a physical article from a digital design. There are distinctive 3D printing advances and materials you can print with, however, all depend on a similar guideline: a computerized model is transformed into a strong three-dimensional physical object by including material layer by layer.
Every 3D print starts as a digital 3D design file on your PC or any supported smart device. This plan document is cut under slim layers which is at that point sent of the 3d printer. One may create this design using a specific software like Blender, or downloading ready to print file from variety websites like, Thingiverse.com or www.shapeways.com.
The printing process varies by technology, starting from desktop printers that melt a plastic material and lay it down onto a print platform to large industrial machines that use a laser to selectively melt metal powder at high temperatures. Time: The printing can take hours to complete depending on the size, and the printed objects are often post-processed to reach the desired finish.
Available materials also vary by printer type, ranging from plastics to rubber, sandstone, metals and alloys - with more and more materials appearing on the market every year.
How do you use it?
To use 3D printing technology one will need:
A 3D printer. Some printers support network printing through Ethernet or Wi-Fi.
Printing materials, plastic or metals or both.
Laptop or supported smart device with a 3D printing or designing Software.
3D file to print, you may download it or design it yourself.
How large it can go?
The have built 10 houses in one day and the cost was less than 5000 using 3D printing tech
How can you use it?
Drew Lentz from MakerBot team teaches how to integrate a 3D printing into a classroom setting. He started by giving a simple definition of what a 3D printing means (a 3D printer is a tool that takes something digital and turn it in physical). Drew also covers the MakerBot in the Classroom handbook and explain what might seem like difficult concepts in a manner that is clear and straightforward.
Advantages of the technology
Create classroom complex designs: 3D printing gives teachers and students a chance to make complex shapes and parts many of which cannot be created by conventional manufacturing methods.
Customize each object: 3D printing takes into consideration simple customization; one just needs to change the design digitally to roll out improvements with no extra tooling or other costly assembling process required to deliver the last item. The outcome? Every single thing can be redone to meet a classroom particular needs without additional manufacturing costs.
Effective production cost: Since there is no expensive tooling required to create objects through 3D printing,
3D printing offers students from from different fields of study a reasonable solution to make their concepts tangible in the early stages of the design process.
Low waste: normally, when an object is manufactured this way, it just uses as much material that is expected to make that specific protest. Moreover, the vast majority of these materials can be reused and re-purposed into more 3D printed objects.
Weaknesses of the technology
Higher cost for classroom: 3D printing is not yet competitive with conventional assembling forms with regards to huge school usage.
Less material choices, colors, and finishes: Regardless of there being more than six-hundred 3D printing materials accessible today – The greater part of which would plastics and metals – the choices are still limited compared to conventional product materials, colors and finishes.
Examples of how may this technology support teaching and learning
Printing 3D fossils models gives Geology students the chance to experience almost real touch to the fossils and stones without having real samples. This increases students engagement.
Students designed and printed their own unique atom model using Tinkercad.com and Maker Bot printer.
Printing useful classroom manipulative for Math, Science, and History.
