Questions to ponder about:
~What is 3D printing?
~How does 3D printing works?
~What are some applications of 3D printing?
It is used to construct physical models directly from a computer-aided design (CAD)
7 different process/technology:
Electron Beam Melting
-Laminated Object Manufacturing (LOM)
~Prototypes are made faster
~Able to produce customized parts
~Able to create more complicated internal models compared to conventional machines
How does it work?
-Similar to squeezing toothpaste out of the tube.
What can you print?
-Food(NASA printing food in space)
-Sports(wheelchair basketball; customized seat)
[Mostly prototypes, moulds and functional parts]
Comparison between modern and traditional hearing aids:
Traditional: A lot of manual work and human intervention, thus high chance of human error.
Modern(3D printing): Using infrared to scan ear structure, automated process and therefore, least chance of errors occurring.
Does not restrict to machine size:
Able to make multiple parts then join them together:
-Central wing span
1) industry use
2) consumer use
-Biomedical research(printing organs)
Efforts made by NTU:
-organised the 1st exhibition in Singapore last year
-specific class for 3D printing
-$30 million research centre
