Rockwell Hardness Test

The Rockwell hardness test is a non-destructive testing method performed by comparing depth of indentations. The test is defined in ASTM E-18 and ISO 6508-1. The hardness test is named after the inventor of the Rockwell hardness tester machine...

Designing for Additive Manufacturing DMLS

As predominantly a welding (or sintering) process, metal 3D printing involves similar design guidelines and approaches with fewer restrictions and variables. Additive manufacturing allows more freedom of design with less constraint, the goal of design engineers since designs first revolved around available manufacturing technologies.

Value Added from Additive Manufacturing or 3D Printing

Additive manufacturing processes can provide value at nearly all aspects of a manufacturing line, whether allowing for the supply chain to be brought in-house or opening the manufacturing capabilities to include far more complex parts. Determining whether integrating a 3D printing process into the manufacturing line will increase or decrease efficiency, though, requires a fairly thorough analysis of past, present, and future projects.

Certification and Testing for Additive Manufacturing

The process of 3D printing metal is very similar to welding and the same issues are generally present. Porosity, cracks, undercuts, and more problems can occur during a printing process. Certifying that the part will work as designed requires testing of the material as well as sample testing of the part. In order to guarantee these tests, prototyping a printing process is important.
