Research Shows that Silicone Resin Prepolymers Can Be Used for Ultraviolet-Assisted 3D Printing

There are many advantages to ultraviolet (UV)-curable systems, like energy saving, rapid curing, environmentally friendly, and high cost performance. These systems are used often with UV-assisted 3D printing, which deposits layers of photocurable liquid polymer crosslinked by an external UV light source to make an object. Silicone materials are promising for 3D printing use due to […]

New Study Shows that SLM 3D Printing Has High Potential for Fabricating Metallic Glass Components

Metallic glass, also known as amorphous metal, was first introduced in the early 1960s, and since then, it seems that everyone wants in on the action. The material is valued for its many exceptional properties, such as low stiffness, near-theoretical strength, high corrosion resistance, and large elastic strain limits. Bulk metallic glasses (BMG), which have characteristic specimen sizes in excess of 1 mm, have […]
