Is there a standard for a 3D Printed Part Drawing? 1

I work in the aerospace and defense industry and wonder if there's a standard and/or examples when creating a 3D Printed part drawing?

Standard Notes?
Do you show Dimensions or make them a reference?

Thank you.

I thought drawings were supposed to be production method agnostic?

I assume the logic is similar to what led to the development of Y14.8 for castings, forgings, and molded parts.

artnmotion,

Will the 3D printed part be modeled and manufactured as per your drawing, or will it be manufactured from the 3D model you submit?

It will be manufactured from the 3D Model.
 
artnmotion,

How much control do you need?

I claim that the standard for drafting is what I inspectability. I send the drawing or some other documentation to the vendor. When the part comes back, I determine whether or not the part conforms to my documentation. The part is not inspectable if...

[ol]
[li]...the part is not fully dimensioned.[/li]
[li]...the drawing is not fully toleranced, and/or the tolerances are not achieveable.[/li]
[li]...drafting standards are not followed.[/li]
[li]...there is no way to inspect it.[/li]
[/ol]

In the absence of a drawing conforming to ASME Y14.5 or some other standard, you need some agreement as to how close the part must come to the model. My experience has been that a rapid prototyping firm will ignore the drawing and fabricate from the 3D[ ]model.

On an ASME Y14.5 compliant drawing, you can apply a note stating that any undimensioned feature must be fabricated to within a 1mm profile with respect to the model.

Sounds like a conversation with a Contractor on a project with "Architecturally Acceptable Welds". There were no viable specs so everybody looked over at a nearby welded hand rail and all decided that those welds would be their comparison spec.
