I'm trying to find the correct way to read and understand the dimensions of a 3D printer. For example, if I read the following dimensions for the Robo 3D R1 Plus as 10x9x8 Inch - I want to know what 10 stands for (does it mean print height?), 9 (depth?), and 8 (width?); etc. I'm not sure if I'm assuming correctly.

I know this should be simple, but I'm not sure where to reference the proper ordering, respective to each aforementioned dimension.


While looking at Makerbot's Replicator technical specifications, I see them listing their dimensions as follows:

Build Volume

29.5 L X 19.5 W X 16.5 H CM [11.6 X 7.6 X 6.5 IN] 

So, if I'm reading this correctly, can I infer that 11.6 IN is referring to the length/depth, 7.6 IN is referring to the width, and 6.5 IN is referring to the height. Would this be the universal/standard way of referring to build specifications for all 3D printers?

Having the dimensions of your 3D printer ordered in Length x Width x Height is a common way, but nobody actually decided it. I think it has something to do with the 3rd dimension being the "new" dimension for printing things, that's why it's appended at the end. Additionally, the first axis on a 2D-coordinate system usually is the horizontal one, so writing Length x Width makes sense for me. If you are unsure you can always test your printer (if you have one) by writing your own G-Code that moves the printhead on a defined axis.
