Getting started with a new prototype has never been easier!
PREPERM® is a perfect match for 3D printing technology
Traditionally, prototyping has been carried out by mechanical machining. However, this is complex, slow and generates material waste. The 3D printing technology constructs objects as successive layers. It is a one-step process and can generate complex internal structures. It significantly simplifies the manufacture process and reduces material waste. Furthermore, 3D printing can create perforated structures that are difficult to achieve by machining due to the mechanical strength of the material.
Premix’s PREPERM® is a perfect match for 3D printing technology. In a recent research project, the PREPERM® solution was used in a 10-GHz lens antenna prototype. The novel dielectric lens was fabricated by using PREPERM® 3D filament (ɛr = 4.4, tan δ = 0.004). The manufacturing process was simple and straightforward - no need for machining or assembly. The dielectric constants were tailor-made and the entire dielectric lens was fabricated in a one-step process. The directivity of the source antenna was significantly enhanced.
