3D Shape Reconstruction of 3D Printed Transparent Microscopic Objects from Multiple Photographic Images Using Ultraviolet Illumination

Micromachines, 2018
We propose and demonstrate a simple, low-cost, three-dimensional (3D) shape acquisition method for transparent 3D printed microscopic objects. Our method uses ultraviolet (UV) illumination to obtain high-contrast silhouette images of transparent 3D ...

Real Time Shrinkage Studies in Photopolymer Films Using Holographic Interferometry

, 2012
Polymerisation induced shrinkage is one of the main reasons why photopolymer materials are not more widely used for holographic applications. The aim of this study is to evaluate the shrinkage in an acrylamide photopolymer layer during holographic ...

Flexo‐printable glucomannan‐based biofilm

Coloration Technology, EarlyView.
Abstract Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA).
