For instance, the parts used in the Aerospace Industry last as long as 30 years while the parts used in the computer industry last about a few years.

Applications of Direct Part Marking Methods
The process of Direct Part Marking is predominately used by electronic, aerospace and automotive manufactures to ensure reliable traceability of their parts and products in the long run. Direct Part Marking helps for data logging for safety, conforming to various safety regulatory requirements and also in warranty issues.

Direct Part Marking and Department of Defense
As per the mandate issued by the United States Department of Defense, all tangible assets must have a physical mark on them in order to be compliant to the Item Unique Identification standards.

Advantages of Direct Part Marking Methods

Especially, it helps in tracking defense related items starting from their date of manufacturing through their entire life cycle. There are many benefits that make the use of direct part marking a bare essential amongst many manufactures around the world.

The favorable economics of high-performance, lightweight engineering plastics parts replacing traditionally more expensive metal parts
The indelible, high-resolution alphanumeric and machine vision codes which the direct part marking produces
The growing requirements for component traceability and product unique identification (UID)

The Most Popular Direct Part Marking Method
Direct part marking is a 2-dimensional barcode which offers lifetime traceability for item components. Usually these codes appear very tiny in the normal vision; however, they contain all the critical information about the items. Since the codes are machine readable, any possible human error is removed. Of many common direct part marking methods available in the industry, Inkjet Part Marking technique is the most popular and is used mostly in the aerospace, electronics, automotive, lumber, home building products, food, medical and packaging industries. As compared to some other means of direct park marking, inkjet part marking offers better resistant for long duration. This marking produces the best quality marks possible on most building products. Aside from the DoD military mandate, manufacturers of many commercial industrial products ranging from automotive, pharmaceutical, and packaging to electronic and consumer goods are now into implementing Inkjet Part Marking as the best form of Direct Part Method.

Other Direct Part Marking Methods
The digital process technology is another popular method of Direct Mark Method which is ideal for a wide rang of items especially 3D plastic products as the process yields high-contrast indelible markings and does not require consumables or curing, thus making it one of the most economical direct part marking solutions. Digital process technology is very helpful for micro-marking when there is limited surface area on a product. Alphanumeric, logos, or schematic diagrams; all can be printed even in the smallest size machine vision codes.
