After the surprising strength of PLA in our PLA flexural strength test, we decided to try something a little different. Let’s just say it involves a Honda S2000. Check it out in the video below.
The real thing now exists and is around 39 feet in diameter, there’s a picture of it attached. There’s also a picture of the model which was made at 1:40 scale, together with an image of the CAD model that I had to construct to be able to 3D print it.
The other amazing thing with this model was it had zero infill and just a 0.8mm wall thickness, yet it withstood the wave-tank forces really well. As well as people under-estimating the strength of PLA they also often over-estimate the amount of infill required to print a model that’s strong enough for their needs.
