Engrave and Fill

To create Engrave and Fill marking, your parts are laser marked or machined engraved, and then the laser-engraved sections are filled with ink, according to your specific requirements.

Engrave and Fill is available on aluminum.

Standards

ProtoSpace Engrave and Fill is a form of marking that is compliant with the following standards:

• MIL-STD-130
• A-A-56023D
• A-A-00208D (US Department of Defense Property)

MIL-STD-130

Laser Marking and Engrave and Fill are permanent marking methods for applications requiring MIL-STD-130 (Table II).

This standard provides criteria for the selection of the application process, as well as all other specific requirements that will be part of the deliverable item, such as marking protocol, content, font size, type, location, etc.

Simply stating in the product definition data that the marking be in accordance with MIL-STD-130 is not sufficient. The item identification marking requirements must be determined by the Design and/or Acquiring Activity in their contractual instruments, and tailored to meet the needs of their specific application.

ProtoSpace is recognized solely and exclusively as the Manufacturer.

The customer is recognized as the Design Activity. They retain full design and quality assurance control, as well as full responsibility to the acquiring activity for the delivered product.

Ink Fill Font Constraints

We recommend using uppercase letters as much as possible because lowercase letters have varying widths in a stroke.
