Fusion 360 material experiment – 3D printing

So I’m on version 24 of my 3D printed unobtanium part….. I keep tweaking the dimensions and re-printing. It occurred to me that Autodesk Fusion 360 thought I was working in Steel, when I’m actually working in plastic. ABS plastic to be precise. Fusion 360 is a really nice CAD/CAM tool that represents the future of software delivery. It’s cloud-connected which means I can work on my project from anywhere, but I still get the power of my 8-core AMD Bulldozer CPU with 3 24″ screens when I’m at my home office.

So I made the inner radius a little smaller. That is the part I’m working on. I then exported the STL 3D model as I always do. And then I went back and changed the part material from Steel to ABS Plastic. I exported that as 16mm ball cap v24-ABS. I put both of them in Simplify3D and we’ll see how it goes. The “steel” one is on the left. The “ABS” one is on the right. The question to be answered is does Fusion 360 compensate when exporting the STL for 3D printing? It’s 3D aware and creates beautiful, defect free STL files.

Here is a screen grab of the Simplify 3D. The thin red lines are the tool paths when not extruding.

And the answer is NO. Both versions are absolutely identical to each other.
