Transcript of 3D Printing

Materials
Procedure:

Photopolymers
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)
SLS FDM
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?
