Different between ISO and ANSI

[steenH797P]

Use Inventor 2016 for models to 3D printer

That is the different of using ISO or ANSI  ?

I am not sure you should see any difference in relation to 3D printing - I thought these standards related to 2D documentation.

I think that for 3D printing the Units are the parameter that you should be aware of.

ISO or ANSI does not matter..

Hello @steenH797P here is a thorough article explaining the two:

What is the difference between ANSI and ISO?

As for your 3D printer, I think you might be wondering why it comes out a different size?

It just depends on the unit options you set the model to, mm or inch. 

See these posts:

Inventor 2016 units ( mm) don't does not match my 3D printer

3D Printing/ standard vs metric system

Hope that helps!

so what is the difference between ANSI Unified screw threads vs iso metric profile? When someone ask me usually say not a thing.  Its a common question.

oops I should be more clear, the difference between ANSI METRIC M PROFILE VS ISO METRIC PROFILE is what I should have said.

Hello @Anonymous there are many different standards and they all vary depending on geography, use, environment, material, etc. Some good information and links:

Differences Between ASME Y14.5-2009 and ISO 1101

I don't think there is a size difference it is just how it is notated? Are you talking about the settings within the annotation type?

A copy of Machinery's Handbook (within the last 25 years or so) would have those standard thread profiles detailed for comparison, as well as many other reference books, and web sites.

The ASME standard is B1.13M, and is available for $72(!) from ASME.  But the information is readily available on line, too.

The basic 60° profiles are the same, but of course the nominal sizes, pitches and minor diameters are different.

Good idea, I don't think there is a difference at all. A m3 is a m3. Just ansi vs iso is different documents.
Thanks for the help sir!!!
