With the world카지노 게임 컬렉션s attention on Queen카지노 게임 컬렉션s physicist Dr. Art McDonald after he received the Nobel Prize in Physics for breakthrough neutrino research, we decided to shine a spotlight on other innovative Queen카지노 게임 컬렉션s physicists.
Professor James Fraser and master카지노 게임 컬렉션s student Allison Sibley study light 카지노 게임 컬렉션 particularly laser light and its uses in manufacturing. They are studying lasers used in 3D printing and the challenge of printing in metal, instead of plastic.
카지노 게임 컬렉션What카지노 게임 컬렉션s going on at the rich and beautiful world at the pinpoint of a laser beam?카지노 게임 컬렉션 says Dr. Fraser. 카지노 게임 컬렉션Energy is hotter than a volcano down there, so you can imagine the physics going on.카지노 게임 컬렉션
And working at that high temperature (around 1600 C to cut metal), they have to figure out what카지노 게임 컬렉션s going on very quickly.
카지노 게임 컬렉션I am imaging the actual process while it카지노 게임 컬렉션s happening so I can detect defects in the parts,카지노 게임 컬렉션 explains Ms. Sibley. 카지노 게임 컬렉션We can change the parameters of the processing laser and correct the defects, stop the process while it카지노 게임 컬렉션s happening.카지노 게임 컬렉션
Their hope is that their research into additive manufacturing, building up with metal, instead of subtracting, will contribute to a number of different areas 카지노 게임 컬렉션 automotive, aerospace, and transportation in general, where small improvements can yield great results.
카지노 게임 컬렉션If you can make a car 10% lighter, that directly translates into reduced CO2 emissions. There카지노 게임 컬렉션s a lot of opportunity,카지노 게임 컬렉션 says Dr. Fraser.

James Fraser: We exploit laser light for fundamental studies of nanostructures; these might have important properties for future technologies. We also exploit laser light to create novel structures.
Allison is looking at the field of laser additive manufacturing, also known as 3D printing. This is a new paradigm for manufacturing: an engineer can create a 3D CAD drawing of a part, press a button, and a system prints out a metal part. At least, that is the goal!
The challenge in 3D writing with lasers is being able to understand what you카지노 게임 컬렉션re doing when you카지노 게임 컬렉션re doing it, and that카지노 게임 컬렉션s what our research is centred on. The point of a focused laser beam is the tool that draws the part 카지노 게임 컬렉션 we want to know what is going on there. Temperatures are hotter than a volcano, so you can imagine the richness and complexity of the physics going on.
Allison Sibley: I work on 3D printing 카지노 게임 컬렉션 imaging the actual process while it카지노 게임 컬렉션s happening.
We take substrate and place a layer of metal powder on it. We take the processing laser over it in whatever pattern we want. We can have our imaging laser on it at the same time, so we can see what카지노 게임 컬렉션s happening. And then when our first layer is done, we lay down a second layer and do the same thing, and we keep doing that until we have our finished cube, or whatever object we카지노 게임 컬렉션re building.
James Fraser: Because we카지노 게임 컬렉션re imaging what카지노 게임 컬렉션s happening when the laser writing process is going on, the user gets immediate information if there is a problem so they can stop the build and correct the problem.
The next step would be automatic control so the system will know how to correct itself. The goal is to have a system that can create optimal structures every single time.
You can now buy commercial units 카지노 게임 컬렉션 you press a button and out comes a part. Most of those are plastic. We work in metal. This is harder to do, because you can make plastic flow at much lower temperatures.
We use the laser to melt the metal and make the shape we want. And again, the metal is hot 카지노 게임 컬렉션 the melting temperature is around 1600 C. It카지노 게임 컬렉션s not at that temperature very long 카지노 게임 컬렉션 you have to figure out what카지노 게임 컬렉션s going on very quickly.
