Title: 3D Printer Measurement Unit
Post by: extreme.aly on September 17, 2014, 08:09:52 AM
Hello, I have a plan to buy a 3D printers, and I google'd about them a lot. One of the most cheap and reasonable I came across was the Two-Up 3D Printer. And I have started making basic 3D objects in AutoCAD.

There's one thing which is not clear to me is, the STL file that we provide to the printer, what are the measurement units used?
In AutoCAD, when I build a 3D object, lets say a cube, it asks me for the dimensions (width, length, height), but it is unit less.

So, do I have to change some settings in AutoCAD or does the 3D printing software by default assumes some units?

Thanks in advance.

I don't design in AutoCAD, but most of the slicers I've dealt with work in millimeters. I typically design in inches, so I end up needing to do a scale of 2540%

Hope this helps!
