The Ultimate Guide to Sealing 3D Printed Parts

Posted by Andy Marin on Thu, May 24, 2018 @ 02:24 PM

When 3D printing was first developed in the 1980’s, it was primarily used for a product’s proof of concept or initial prototypes. The limits of the technology and material did not allow one to use the process for field testing, or production. The past decade has seen a surge in 3D printing use. The rapid developments in 3D printing technology and materials has accelerated areas like product development, offer customized product, and eliminate design restrictions.

How Nondestructive X-Ray Inspects Casting Porosity

Posted by Andy Marin on Fri, Apr 06, 2018 @ 08:35 AM

The term porosity is used extensively when talking about any void in a casting, but it does not describe the actual problem. It can take many different shapes and forms, but it is often described just as “porosity”. When analyzing a casting’s porosity, it is important to describe specifics like size, shape, location, and frequency. Since porosity is within the casting’s walls, the best way to analyze it is through Nondestructive Testing.

Sealant Testing: What Can a Sealant Slug Tell You?

Posted by Andy Marin on Tue, Mar 13, 2018 @ 11:22 AM

Vacuum impregnation is a process that seals porosity in metal castings. If left untreated, then the porosity creates a path for fluids and gasses to leak from the part. When performed properly, vacuum impregnation seals the porosity, but it is undetectable on the surface or in the machined features of the casting.
