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...

Additive Manufacturing In article number 2103334, Hilmar Koerner and co-workers discuss how, with the growth in additive manufacturing, such as 3D printing, nanocomposites have experienced a resurgence due to novel emergent material properties, which are enabled by digitally dialing morphology over several length scales. Topology optimization of printed takes this another level unprecedented co...

Soft Tissue Engineering In article number 2215220, Scott J. Hollister, Michael E. Davis, and co-workers report, 3D printing of a novel architected auxetic with enhanced mechanical biological performance. Specifically, the printed auxetics have high flexibility, permeability, nonlinear deformation behavior as demonstrated through computational, mechanical, analysis. These characteristics provide...

In article number 2100245, Crystal E. Owens, Gareth H. McKinley, A. John Hart and co-workers present a direct-write printing process controlled by two parameters to extrude aqueous carbon nanotube (CNT) solutions with liquid crystalline behavior, drawing highly conductive flexible traces, sensors, circuits integrated circuit elements onto variety of substrates. The high CNT concentration lack f...

Bioresins Light-responsive microgels enable combination of embedded extrusion and volumetric bioprinting. In article number 2301673, Riccardo Levato co-workers report the development granular bioresins as a suspension bath for printing multiple cell types. Within seconds, is shaped into complex 3D constructs with micro-to-macro, multiscale porosity, upon tomographic light exposure, building adv...

The 2019-2021 coronavirus pandemic (COVID-19), which began in the city of Wuhan China, towards end 2019. As March 12, 2020, World Health Organization ordered disease 2019 (COVID-19) as a pandemic, at time its composition, has spread to more than 180 countries on planet. number COVID-19 patients is rise worldwide; given high and disruption production network; this created shortage clinical parts...
