Additive Layer Manufacturing (ALM) provides a new freedom to design to RF components with the goal to increase performance, to reduce mass and to decrease schedule and cost by a higher level of integration directly manufactured. The whole process chain of ALM including post processing for RF components was investigated and especially the electrical effect of the surface roughness including...

Radiofrequencies parts have been identified by TCS as one of the most interesting applications for additive manufacturing. Indeed, these technologies could allow to:
• Decrease dramatically delivery time : from several months with traditional processes to few days
• Make one-piece part instead of assembly of several parts, allowing remove of interfaces which could cause dB losses....

This presentation will focus on the development of waveguide microwave filters through two different additive manufacturing (AM) techniques: selective laser melting (SLM) and stereo-lithography (SLA).
A robust architecture of Ku/K-band passband filters compatible with AM mechanical tolerances will be described. This architecture has been implemented into two different...

The presentation will describe the development of resonator and coupling architectures that enhance the insertion loss and far out of band rejection of single mode waveguide filters. The inherent geometrical freedom of 3D additive manufacturing techniques is exploited to realize complex geometries monolithically. It also has the added benefit of reduced manufacturing lead time. Resonator and...

Additive Manufacturing (AM) is gaining a lot of popularity in the space industry due to the lightweight of the 3D printed components and its versatility when producing complex monolithic 3D geometries. Even though it is not a new technology, the technological improvements in 3D printers are making them more accurate, reliable and affordable than ever. This is why many companies, universities,...

Over the past three years, a collaboration between Imperial College London and the National Physical Laboratory (NPL) has investigated the RF performance limits of 3D printed X-band and W-band metal-pipe rectangular waveguides (MPRWGs). The metal coated FDM and SLA parts have a measured performance comparable with commercial MPRWGs [1]; demonstrating measured dissipative attenuation levels of...

Dielectric materials can be found in RF/microwave filters for a wide range of industrial applications. Compared with other technologies, dielectric resonator (DR) filters offer a perfect balance between performance and miniaturization. These structures are capable of handling high-power levels while providing a quality factor (Q) comparable to that of pure waveguide implementations. In...

Abstract: 3D printing is delivering step changes in fields such as rapid prototyping and additive manufacturing, and it has plenty of potential for a continuous growth in different applications. Fused deposition modelling (FDM), or fused filament fabrication, has recently become readily available. High frequency and microwave technologies could benefit from it. However, the plastic materials...

In this presentation, the possibility of locally modifying the effective dielectric permittivity by changing the infill factor of the printing process is exploited and demonstrated by using the fused deposition modeling (FDM) technology. This allows adopting a single filament material to obtain different permittivity values in the various portions of a microwave component. Moreover, the...

In this contribution a novel evanescent waveguide dual-channel bandpass filter is proposed. The structure is suitable for additive manufacturing as the inner evanescent structure containing elliptical posts attached to a metallic wall is placed in the middle of a standard waveguide. Since the whole filter should be manufactured as a single piece, only additive manufacturing is able to...

This paper deals with a novel additive micro-fabrication process for millimeter-wave components. This fabrication process is based on successive lithography, metal electroplating with micron scale accuracy, well suited for millimeter-wave filter fabrication. As an additive fabrication process, the millimeter-wave components can be fabrication on many types of substrates, like PCB or ceramics....

During the past couple of years, SWISSto12 has developed a proprietary additive manufacturing (AM) technique for the production of RF components. The technique combines high mechanical precision (+/-25 um locally) and low surface roughness (a few hundred nanometers). In essence, it consists of two main steps: first a polymer-based body of a piece is fabricated by stereolithographic (SLA) AM...

3D screen printing is an additive manufacturing technique based on the combination of screen printing and sintering. It is well suited for the manufacture of parts with fine details, complex structures, cavities and material combinations. Ceramic and metal powders are processed into suspensions which are deposited using a screen printing screen. Repetition of this process allows for a layer by...

The design freedom of Additive Manufacturing (AM) is both an advantage and a challenge. More than ever, we need assistance from the computer in exploiting the manufacturing capabilities. Even though Computer-Aided Design (CAD) has been around for 40 years, it is still not ready to fully support design for AM. Meanwhile, the fields of structural optimisation and generative design have developed...
