    Print area vs Print volume. LulzBot Mini vs Ultimaker 2 Go

    Hello everyone!

    Im a little confused here (this will be my first 3d printer) What is the difference between print area and print volume? The mini has a print area of 6x6x6.2 in but a print volume of 223 in3. The GO has a print area of 4.72x4.72x4.53 in, but a print volume of 633 in3. So to help my simple mind, which could print a larger square?

    Thanks!

    The print volume of the Ultimaker 2 GO is not 633 cubic inches. The print dimensions i found (12 x 12 x 15.5 cm) work out to about 136 cubic inches. No idea where you got the 633 figure from.

    The cube root of 633 is 8.586205. The build volume would have to be about 8.6 inches (21.84 cm) per axis.

    Thank you very much for the help. That makes sense.

    I got that information from here

    That's what they say on that page alright, but something's wrong somewhere.
    - If we multiply 12 x 12 x 11.5 we get 1656 cubic cm (i do anyway). When i convert that into cubic inches, on my handy dandy Windowz calculator/converter, it works out to 101 cubic inches - less than i figured out above.
    - Converting the length measurements first to inches:
    12 cm = 4.72" and 11.5 cm = 4.53"
    Therefore 4.72 x 4.72 x 4.53 = 100.9 cubic inches.

    So, my original calculation of 136 cubic inches above was off, and the build volume appears to be 101 cubic inches. Why the manufacturer shows "10608 cm3 [633 in3]" as the build volume is a mystery. It doesn't inspire much confidence. It might be worthwhile emailing them and asking about it. Perhaps we've missed something obvious.

    how about just using cm and litres as volume ?

    Seriously dose anybody actually use inches for anything technical ?

    Only homebrew niche hobbies, like the aerospace industry.

    I don't get the Ultimaker 2Go. Students cannot afford it, and the ones that can can also afford to drive a car to transport larger machines. Right, this one frees up more space for groceries or fits into the rear of a Twizy or Smart car. Are they envisioning some kind of mobile inner city 3D print delivery service? Then it would also have to be able to keep printing while on the go.

    Simpler than that - they saw lots of people buying small printers and thought it was because they were small.
    They didn't realise that people were buyign small printers because they were really cheap - something an ultimaker will never be.
