In this study, a combined aroma finishing and pigment printing process was investigated in order to develop 1-step, all-in aroma finishing/pigment printing process for Thai silk. Lemongrass oil microcapsules, an aroma finishing agent, was applied on silk by screen printing process and the properties of the printed fabrics were examined. Pigment printing was also performed individually by screen printing and the colorimetric properties of the print were measured. Binder content affected the print properties of both aroma microcapsules and pigment on silk. An appropriate binder content was chosen at 20 g/100 g print paste. The 1-step, all-in aroma finishing/pigment printing process was performed by printing both lemongrass oil microcapsules and pigment simultaneously on silk fabrics. The process efficiency was determined in two different aspects i.e. aroma finishing effect and coloring effect. Aroma finishing effect of the 1-step, all-in process was examined in comparison with the individual microcapsule print results while the coloring effect was compared between the printed fabric from 1-step, all-in process and the individual pigment printing. The results showed that the 1-step, all-in process could provide comparable aroma finishing effect and pigment print quality to the separated finishing and pigment printing processes.

Potential Use

The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. The products decorated by In-Mold Roller are protected from water and fading. These kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate the potential use of combining In-Mold Roller with digital inkjet printing in 3D decoration, e.g. in personalized printing services. The study results found show that digital inkjet printing to the PET film and then transfer to the ABS, the solid ink densities (SIDs) of primaries would increase. The tone values increases (TVIs) from highlight and middle (around 0~60%) were generally higher than those in shadows. The shapes and sizes of color gamut were also varied according to different kinds of digital UV inkjet printing processes. Moreover, after transferred, the color gamut became smaller.

With the development of the green inks, UV ink has been applicated wider and wider in the printing, packaging and the electronics industry. Based on the UV inks and screen printing process, this paper has investigated the influnce of mesh count, screen ruling, printing materials and ink viscosity on print quality by measuring the printing dot gain experimentally. The results show that the higher mesh count and more smooth printing material can induce the better dot, tone reproduction and higher printing precision. The more serious dot gain and the worse tone reproduction will induced by lower ink viscosity. The higher screen ruling cause the bigger dot gain value. Bigger rate of mesh count with screening ruling can reduce the moire phenomena.

This work are made for determine the possibility of generating the specific parts of a threaded assembly. If aspects of CAD generating specific elements was analysed over time in several works, the technological aspects of making components by printing processes 3D through optical polymerization process is less studied. Generating the threaded appeared as a necessity for the reconditioning technology or made components of the processing machines. To determine the technological aspects of 3D printing are arranged to achieve specific factors of the technological process, but also from the specific elements of a trapezoidal thread or spiral for translate granular material in supply process are determined experimentally. In the first part analyses the constructive generation process of a spiral element. In the second part are identified the specific aspects that can generation influence on the process of realization by 3D DLP printing of the two studied elements. The third part is affected to printing and determining the dimensions of the analysed components. We will determine the specific value that can influence the process of making them in rapport with printing process. The last part is affected by the conclusions. It can be noticed that both the orientation and the precision of generating solid models have a great influence on the made parts.

The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. Products decorated by In-Mold Roller are waterproof and protected from fading. What’s more, these kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate potential usages of combining In-Mold Roller with digital UV inkjet printing in 3D decoration, e.g. in personalized printing services. Study results found that when the coverage and the resolution of inkjet printing become higher, the SIDs will become higher as well. When transferred to ABS, SIDs in each combination will increase. Each combination of inkjet conditions, with the isolation of white ink, color differences are less variant. TVIs of white ink decrease 30% to 40% halftone and display in “M” type. In print contrast, C and K colors of each combination are better than M and Y colors. After transferred into print contrast, each combination of PC will be higher about 2 to5. When transferred to ABS, color variances of each combination are not huge, and color differences are about 3to5.

AbstractThis study demonstrated the first case of combining novel continuous granulation with powder-based pharmaceutical 3-dimensional (3D) printing processes to enhance the dissolution rate and physical properties of a poorly water-soluble drug. Powder bed fusion (PBF) and binder jetting 3D printing processes have gained much attention in pharmaceutical dosage form manufacturing in recent times. Although powder bed-based 3D printing platforms have been known to face printing and uniformity problems due to the inherent poor flow properties of the pharmaceutical physical mixtures (feedstock). Moreover, techniques such as binder jetting currently do not provide any solubility benefits to active pharmaceutical ingredients (APIs) with poor aqueous solubility (>40% of marketed drugs). For this study, a hot-melt extrusion-based versatile granulation process equipped with UV-Vis process analytical technology (PAT) tools for the in-line monitoring of critical quality attributes (i.e., solid-state) of indomethacin was developed. The collected granules with enhanced flow properties were mixed with vinylpyrrolidone-vinyl acetate copolymer and a conductive excipient for efficient sintering. These mixtures were further characterized for their bulk properties observing an excellent flow and later subjected to a PBF-3D printing process. The physical mixtures, processed granules, and printed tablets were characterized using conventional as well as advanced solid-state characterization. These characterizations revealed the amorphous nature of the drug in the processed granules and printed tablets. Further, the in vitro release testing of the tablets with produced granules as a reference standard depicted a notable solubility advantage (100% drug released in 5 minutes at >pH 6.8) over the pure drug and the physical mixture. Our developed system known as DosePlus combines innovative continuous granulation and PBF-3D printing process which can potentially improve the physical properties of the bulk drug and formulations in comparison to when used in isolation. This process can further find application in continuous manufacturing of granules and additive manufacturing of pharmaceuticals to produce dosage forms with excellent uniformity and solubility advantage.Abstract Figure

With high effective screen-printing process, the field emission display panel with double stripe emitters was fabricated and their good field emission property was also characterized. Using sintered silver slurry with better electric conduction property as material, the cathode electrode including two parts was formed. The top cathode electrode was made up of two silver stripes, which the carbon nanotube material would reside on its surface. The bottom cathode electrode was separated by the cathode separate layer with the top cathode electrode, but the electric-connection would be performed between them through the preformed round holes. Using carbon nanotube as cathode, the field emission display panel with double stripe emitters was demonstrated.
