Additive manufactured RF components

(request a quote)

SWISSto12 supplies additive manufactured (3D Printed) RF antenna, waveguide and filter components. The company specialises in product designs, which are 3D printed in high-performance polymers and subsequently metal plated through proprietary processes (pat. pend.). This novel approach to manufacturing replaces traditional machining of metallic materials. In this context, SWISSto12 products feature drastic weight reductions, extended design flexibility and reduced production costs.

SWISSto12 either manufactures RF designs specified by its customers or RF designs components from specifications before proceeding with manufacturing.

Revolutionary
The use of 3D printing open up possibilities for RF structures that were previously impossible to manufacture with conventional techniques. The use of plastics allows for weight reduction and thermal insulation. High quality copper plating ensures state of the art RF performances.

Competitive
The performance of SWISSto12's 3D printed components competes with conventionally manufactured components. Custom products are possible with reduced lead times and attractive costs.

Enabling
3D printing enables fast manufacturing of both standard and custom components. Typical lead times are of 2-4 weeks.
