People are often amazed at how lightweight and strong our 3D printed Nylon plastic can be with the correct geometry. It is an important part of the design process to test your 3D printed designs to breaking point. Prototyping a product before releasing it for sale to others in your Shapeways shop is essential to ensure that your design will stand up to the stresses of use, and not make your customers find out for you.
“People keep asking me, how strong is that printed chassis. My answer usualy was..”uuhhmm pretty strong I think”
People keep asking me, how strong is that printed chassis. My answer usualy was..”uuhhmm pretty strong I think”… Well since version 3 is being build right now, I have version 1 and 2 lying around doing nothing. Might as well break one to see how much force it takes. And now for the scientific part, torque is force times lever-arm distance…
In this case the distance from the applied torque to the scale (to measure the force) is about 20 cm (about 8 inch). The force measured at the time of the snap is about 2 Kg (2000 g or about 4.4 lbs). This means the torque applied at the time of the snap is probably more than it will ever be driving the chassis around on any trail….
