The closer a crash test dummy is to a real human body the more effective it is at showing just how safe a car is and exposing flaws in the design. The exact accuracy of a crash test dummy though is nigh on impossible to achieve though every year designs improve with the material more like human flesh, structure more like bone and joints working more like those of a human.Progress is still slow though and there are more lives which could be saved.

One problem with crash test dummies which are realistic, is that the more realistic they are the more difficult they are to make and the more time consuming they are to make. Humanetics Innovative Solutions of Ohio supply several industries including car makers, aviation companies and the military with Crash Test Dummies, or to give them their real name anthropomorphic test devices. They are already highly successful but are now using 3D printing service technology to get one step ahead of competitors. 3D printing services they use drastically cut down on the costs and time needed to make a Crash Test Dummy or more importantly the molds needed. The cost saving comes from far less man hours having to be expended as the process is automated from a 3D CAD file rather than aluminum molds made by hand and also the amount of waste material is virtually zero: important where expensive materials are in use they save hundreds of dollars in materials each time.
