The (nearly) infinite possibilities of 3d printing

Submitter: Jorrit Siebenga
Description: Additive manufacturing, or just 3d printing, has become a serious addition within many production and prototyping facilities. Here at ASTRON, its immense benefits have already been explored for a few years now.

These images show two custom-made parts, which have successfully been implemented as part of the design effort for accurate time distribution within the SKA1 telescopes. This requires the use of wavelength stabilized (DWDM) lasers, and external DWDM filters. For more information see Stewing White Rabbits.

  • The top picture shows the parts of the assembly forming a plug-in module to secure a DWDM filter. It consists of a spool housing and covering knob, to store and secure the DWDM filter and its connecting fibers. The design also includes a metal bracket fixing the fiber connectors to the front plate.

  • The bottom image shows an elegant but efficient solution to neatly secure optical DWDM filters inside a fiber splice tray. The part also offers safe guidance of the connecting fibers, ensuring that the allowed minimum bend radius is maintained.

  • The middle row of photos shows the parts inside the equipment that they have been designed for.
    And there you go, another custom-made integrated fiber-electronic-mechanic solution successfully covered by the great benefits of 3d printing.
