How to Seal 3D-Printed Parts: Ultimate Guide to Eliminating Porosity

When 3D printing was first developed in the 1980s, it was primarily used for proof-of-concept models or initial prototypes. Early limitations in technology and materials meant that 3D-printed parts were rarely suitable for field testing or production. However, the past decade has brought rapid advancements in additive manufacturing. These advancements have allowed for more sophisticated […]

What’s the Difference in Gas and Shrinkage Porosity?

Porosity is any void or hole in, or on, a casting and is caused by gas formation or solidification shrinkage that occurs while the metal solidifies. If the casting needs to be pressure tight, porosity can allow gas and fluids to seep from the part. In this blog, we will discuss the difference between gas […]

Die Casting Porosity

How to Seal Die Casting Porosity?

Die casting is a metal casting process that involves injecting molten metal into a die using high pressure. Die casting facilitates the production of hundreds or thousands of pieces with high dimensional accuracy and a good surface finish, making it highly economical; however, maintaining quality and consistency at such high volumes comes with its own […]
