Transcript of 3D Printing


Ultra Violet Light
Laminant Layers
CAD/CAM (computer-aided design/computer-aided manufacturing)
Vessel of liquid polymer that hardens
Most rapid technique
"Cut" into thin horizontal slices
Computer-controlled laser

3D Printing
By: Juvia Davis, Kiana Krahulik, Brian Dorn, Jenna Solfisburg
What is 3D printing?
Why does 3D printing matter?
This provides teachers with 3 dimensional visual aids
enhances hands on learning
provides more room for interactive class activities
Biology: model, human body

History behind 3D Printing
Who made it?
Charles Hull
Thank you!
About him:
Design engineer at UVP
Grew up in rural Western Colorado
B.S. in engineering physics
Moved to California; engineer at two places (worked on analytical equipment for chemists)
Manufacturer of UV products
Developed an idea that led to 3D printing
Process of making a three dimensional solid figure from a digital file
Created by laying down successive layers of material until the entire object is created
Seen as thinly sliced horizontal cross-section of the soon to be object
The Future of 3D Printing
Stereolithography (SLA)
How Does 3D Printing Work?
Make a virtual design of the object trying to be created
Software put its into layers
Melting or softening methods used to model object together
3 different types of methods that are used (SLS, FDM, SLA)
Fused Deposition Modeling (FDM)
Layer-by-layer, bottom up
Heating and extruding thermoplastic filament
Semi-liquid state
Break away support material or it dissolves into water
Tiny particles of plastic, ceramic, or glass fused together
Heat from high-power laser
Various Powders- atomic diffusion
Sintering is used for jewelry, bricks, and porcelain
Common plastics
3D printers can make prosthetic limbs for $100 when a conventional ones are over a $1000
A company customized a 3D printing machine to make candy from ingredients such as chocolate, mint, sour apple, and cherry.
Scientists are hoping that bio printing someday will enable them to take cells from a working organ to making them useful for testing new drugs or even as organ transplants.
Engineers has gone a step further and printed an entire car and the vehicle that took about 2,500 hours to make.
Selective Laser Sintering (SLS)
Worked in buisness (Made tough coatings and tables - using UV light)
Wanted his own lab to experiment with the UV light - blueprints and designs would not be used until a while later
Observed: thousands of thin layers created three dimensional objects
Special instructions which were described by CAD/CAM
First object - small cup (March 9th, 1983)
How was it made? Where did it come form?
