Longitudinal phase space (LPS) manipulation is critical and necessary for advanced acceleration concepts, radiation sources and improving the performance of x-ray free electron lasers. Here we present a simple and versatile method to semiarbitrarily shape the longitudinal phase space of a charged bunch by using wakefields generated in tailored dielectric-lined waveguides. We apply the concept in simulation and provide examples for radiation generation and bunch compression. We finally discuss the manufacturing capabilities of a modern 3D printer and investigate how printing limitations, as well as the shape of the input LPS, affect the performance of the device.
