Carcinogenic risk in printing industry: A comparative assessment of occupational exposure to solvents across offset, flexographic, and gravure techniques

Ecotoxicology and Environmental Safety
Volatile organic compounds such as benzene, toluene, ethylbenzene, and xylene, with ethyl acetate, propanol, and ethanol, are commonly used in printing and pose health risks to workers. Despite numerous studies in printing, comprehensive risk assessments

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

Elimination of the Solid Graininess Issue with Different Micro-Pattern Structures at Flexo Printing

Applied Sciences
Flexo printing is a relief printing system, and ink transfers on the solid areas are not transferring well during the printing. That is why graininess is increasing and pinholes are occurring on the solid areas.

Research progress of gravure printing solar cells

Flexible and Printed Electronics
Abstract Gravure printing is a two-dimensional patterning, high-precision, high-speed, and roll-to-roll large-area fabrication method that is expected to directly and rapidly fabricate solar cell modules with high geometric fill factor without the need for laser scribing, thus significantly reducing the fabrication cost of solar cells.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
