is it possible to print Lego Technic parts by 3d printer?
there are several 3d designs of Lego Technic parts .can be these designs used to print Lego parts by using 3d printer ?if not , which other methods exit to get hard-copy of these designs .
You can try to print the models on a 3D printer, but the result will most likely be terrible.
Cost is another factor. Lego bricks cost about $0.10 each when purchased as a set, I suspect you'd need to print a lot of bricks (even if the quality was high enough) to offset the cost of the printer.
To get a hard-copy of the Lego models, check out www.lego.com
A site like http://www.brickowl.com will allow you to purchase specific bricks and colors if you are looking to create a custom model.
