Printing systems of hydrographic organisations are systems of preparation/prepress and reproduction of sea charts and navigational publications. Different procedures (conventional and digital) indicate the necessity to optimise reproduction procedure ( T., Kasum, J., 2006). Conventional printing system refers to conventional cartographic processing of the original and copying procedures for pro...

3D printing has emerged as a method for directly printing complete microfluidic devices, although printing materials have been limited to oxygen-impermeable materials. We demonstrate the addition of gas permeable PDMS (Polydimethylsiloxane) membranes to 3D-printed microfluidic devices as a means to enable oxygen control cell culture studies. The incorporation of a 3D-printed device and gas-perm...

We report on inkjet printing of aqueous colloidal suspensions containing monodisperse silica and/or polystyrene nanosphere particles and a systematic study of the morphology of the deposits as a function of different parameters during inkjet printing and solvent evaporation. The colloidal suspensions act as a model ink for an understanding of layer formation processes and resulting morphologies...

Pretty printing is the task of nicely formatting tree structured data within a given line width limit. In 1980 Oppen published a pretty printing algorithm that takes time linear in the size of the input, independent of the line width, and uses only limited look-ahead. This work inspired the development of a number of purely functional pretty printing libraries in Haskell. Here I present a new f...

In the current scenario of flexible manufacturing processes, the 3D printing shows up as an alternative to generate individual parts with complex geometries. Moreover, the development of the 3D printing machines, software and parameters allows the manufacture of parts in some materials suitable for implantation. In this way, this study investigates the feasibility of the production of patient-s...

Recent developments in 3D printing technologies and design have been nothing short of spectacular. Parallel to this, development of bioinks has also emerged as an active research area with almost unlimited possibilities. Many bioinks have been developed for various cells types, but bioinks currently used for 3D printing still have challenges and limitations. Bioink development is significant du...

As electrohydrodynamic jet (e-jet) printing technology developments have increased in magnitude over the past few years, a low-cost and user friendly, high-resolution desktop system was developed at the University of Illinois at Urbana-Champaign. The original desktop system provided great functionality but it could be improved upon. Along with bettering the hardware of the technology, a more in...

PURPOSE Skin cancer is the most common tumor in the population. There are different therapeutic modalities. Brachytherapy is one of the techniques used, in which it is necessary to build customized moulds for some patients. Currently, these moulds are made by hand using rudimentary techniques. We present a new procedure based on 3D printing and the analysis of the clinical workflow. MATERIAL ...

Electrohydrodynamic (EHD)-inkjet printing is a novel high resolution inkjet printing technology with the advantages of being a maskless, non-contact, direct-write and additive process. Its printing resolution exceeds by about two orders of magnitude in comparison to the conventional inkjet printing systems. It is used in the field of micro/nano manufacturing for patterning of large class of mat...
