Rheology and Printability: A Survey of Critical Relationships for Direct Ink Write Materials Design
Daniel Rau,Michael J. Bortner +1 more
TL;DR: This review surveys rheological characterization techniques and relationships for Direct Ink Write (DIW) materials design, providing guidelines for predicting printability and identifying rheological requirements for successful DIW inks, with a focus on bridging and printability maps.

Thermotropic orientational order of discotic liquid crystals in nanochannels: an optical polarimetry study and a Landau-de Gennes analysis.
Andriy V. Kityk,Andriy V. Kityk,Mark Busch,Daniel Rau,Sylwia Całus,Carole V. Cerclier,Ronan Lefort,Denis Morineau,Eric Grelet,Christina Krause,Andreas Schönhals,Bernhard Frick,Patrick Huber,Patrick Huber +13 more
TL;DR: In this paper, optical polarimetry measurements of a discotic liquid crystal based on a pyrene derivative confined in parallelly aligned nanochannels of monolithic, mesoporous alumina, silica, and silicon as a function of temperature, channel radius (3-22 nm), and surface chemistry reveal a competition of radial and axial columnar orders.

A Rheology Roadmap for Evaluating the Printability of Material Extrusion Inks
TL;DR: A Rheology Roadmap is developed to evaluate the printability of Material Extrusion Inks, guiding material designers through systematic rheology experiments to predict ink behavior and compatibility for Direct Ink Write Additive Manufacturing, regardless of ink attributes.

A Rheological Approach for Measuring Cure Depth of Filled and Unfilled Photopolymers at Additive Manufacturing Relevant Length Scales
TL;DR: In this article , an experimental method that uses an ultraviolet (UV) photorheometer to enable accurate and repeatable measurements of cure depth for a wide range of photopolymers is introduced.
