3D-Printed Objects for Multipurpose Applications

Visual perception of 3D printed translucent objects

In order to reproduce translucent objects by 3D printers employing fully transparent (or clear) material, modeling the human visual perception of translucency is crucial. In this preliminary study, a set of 256 texture-less samples was created by mixing white and clear materials using multi-jet 3D printing. The samples differ in both lateral light transport properties and transmittance. Two psy...

A Small Printed Quadrifilar Helical Antenna for BGAN/GPS Applications

This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the fou...

ColorMod: Recoloring 3D Printed Objects using Photochromic Inks

Recent research has shown how to change the color of existing objects using photochromic materials. These materials can switch their appearance from transparent to colored when exposed to light of a certain wavelength. The color remains active even when the object is removed from the light source. The process is fully reversible allowing users to recolor the object as many times as they want. S...
