3D printed titanium parts
itsme:
well my hotmail account doesn't show any messages from bikeguide now...
I thought of something earlier after seeing stuff about how when you print/sinter/deposit metal stuff, it has different properties from machined blocks, like the whole thing is made of weld bead.
There are a few companies using giant metal printers right now, that can have layers on the micron-scale, and if stuff gets better/cheaper in the future, someone will definitely try printing car/bike rims. You could do all kinds of crazy internal modeling, then polish and anodize them, and they'd be perfectly flat/true without a seam... Mag wheels in the future are going to be sweet.
Example - the giant medallion at around 2:30 in this - http://www.youtube.com/watch?v=LuXvZt887D8 - plus the fact that the materials cost for the mesh hand was less than 80 dollars.

I wish I had a billion dollars.

I don't understand why so much of the bike stuff goes uncolored...
"Scientists have 3D printed giant titanium bugs..."
"Australian scientists have created a customized set of purple titanium shoes for a Melbourne race horse using 3D printing."

read something the other day about f1 teams and aircraft manufacturers using 3d printing for components. not on a large scale, but still very cool. int he next few years i bet well start seeing a lot of 3d printed big bike stuff

In the video of the dropouts he specifically claims that they couldnt have made those dropouts any other way and yet that is rubbish. You could investment cast them for a relatively low tool cost.

i clicked on this topic specifically to see the rant that i knew you would put in here. You dont know that for a fact, that is speculation. Just because you have some sort of cut rate 3-d printer at home doesnt make you any kind of expert in the field, nor does reading about it in forums or internet articles. Any time i see a topic about something new that you are doing it is you talking about how it is the best thing around and every time i see a topic about a new process that you didnt adopt it is bashed on or questioned. get over yourself.

--- Quote ---Chief Architect Cong Sun recently unveiled that 3D printing has been widely used in designing and producing of the newest J-15 prototype which had its first successful test in October 2012. 3D printing has been used to manufacture critical titanium alloy load-bearing structure on the aircraft, including the entire nose landing gear.
China aims to become a leader in commercializing 3D printing technology to manufacture titanium parts in aviation industry. The laser additive manufacturing technology could save 90% of raw material, and the cost is only 5% of the traditional method - for example, the cost of a part made with traditional technology is 25 million RMB (4 million USD), but using laser additive manufacturing technology the cost is only 1.3 million (210K USD). Because no tooling is required, the processing charge is also just 10% of the orginal.
