Objective. To identify socioeconomic situation factors and behavioral factors associated with the prevalence of acute symptoms among 150 printing workers in 16 printing factories in Southern Thailand. Materials and Methods. A cross-sectional study was conducted by interviewing 150 printing workers in 16 printing factories in Southern Thailand. Results. Acute symptoms comprised dizziness, drowsi...

This paper discusses the design and integration of a desktop system for electrohydrodynamic jet (E-jet) printing. E-jet printing is a micro/nano-manufacturing process that uses an electric field to induce fluid jet printing through micro/nano-scale nozzles. This enables better control and resolution than traditional jet-printing processes. The printing process is predominantly controlled by cha...

With the development of 3D printing technology, 3D printing has recently been applied to many areas of life including healthcare and the automotive industry. Due to the benefit of 3D printing, 3D printing models are often attacked by hackers and distributed without agreement from the original providers. Furthermore, certain special models and anti-weapon models in 3D printing must be protected ...

Three-dimensional (3D) printing has been particularly widely adopted in medical fields. Application of the 3D printing technique has even been extended to bio-cell printing for 3D tissue/organ development, the creation of scaffolds for tissue engineering, and actual clinical application for various medical parts. Of various medical fields, craniofacial plastic surgery is one of areas that pione...

Color printing proceeds with multiple halftone separations overlay. Because of separation overlay misalignment in printing, the percentage of different primary color combination may vary and it will result in color shift. In traditional printing procedure with AM halftone, every separation has different screening angle to make the superposition pattern in a random style, which will reduce the c...

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

3D printing is a method of manufacturing in which materials, such as plastic or metal, are deposited onto one another in layers to produce a three dimensional object, such as a pair of eye glasses or other 3D objects. This process contrasts with traditional ink-based printers which produce a two dimensional object (ink on paper). To date, 3D printing has primarily been used in engineering to cr...

3D printing has now been recognized as a very practical technique to create 3D structures with milli-/micron-scale resolution. In tissue engineering, particularly, people utilize 3D printing technique to integrate biodegradable polymers to tissue scaffolds. Hydrogel is highly potential material that provides aqua environment and enables nutrition and oxygen transportation, all of which are requ...

DECprint Printing Services software controls a variety of printer features for a wide range of printers. It supports several different page description languages, handles multiple media simultaneously, and uses different I/O interconnections and communication protocols. Operating within the VMS printing environment, it implements a large number of user-specified options to the PRINT command. DE...

This paper examines the effects of the dramatic changes incurred in the sector of printing and publishing after the introduction of digital printing. The print production process is rapidly shifting from analogue to digital technologies as the infrastructure (or basis) for workflows. The efficiency of the production process requires the digitalisation of all steps and elimination of analogue me...
