Medical Case Study: CTI Renato Archer. “We needed highly accurate, multi-material 3D printers; the Fortus adapts well to industrial applications and the Connex is useful in medical applications.” — Jorge Vicente Lopes da Silva, head of the 3D technologies division in Renato Archer’s Information Technology Center Skull reconstruction Renato Archer used its Fortus 3D Production System for its durable materials.

Medical Case Study: CTI Renato Archer

Connex technology helps Renato Archer develop medical prototypes that require flexibility with its range of rubber-like materials. Renato Archer’s Information Technology Center also serves hundreds of area hospitals with its 3D printing capabilities. Innovation and scientific rigor drive Renato Archer researchers’ every step.

CTI has used Stratasys 3D Printers since 2005. Prototyping a New Skull One such medical application was to help a 12-year-old boy who lost part of his cranium in an accident and needed reconstructive surgery on his head. Supporting Hospitals. ROWIAK GmbH - Photons at Work: MyFemto. The surgeon’s skills, his experience and his creativity must be supported by equipment which is designed to meet his induvidual needs.

The tools have to fulfill the surgeon’s special demands and should be adjustable until they feel like a part of his own body. Femtosecond Lasers have opened a new dimension in ophthalmic surgery. Two forces drive the future of femtosecond lasers in ophthalmology: The experience and the creativity of the surgeon and the congenial manufacturing of physicists and engineers. Outstanding surgical procedures can be performed in many different ways, depending on the experience and the skills of the surgeon. Ophthalmic surgery has extremely high requirements in regar to precision and safety. The machines are highly standardized for economic and for safety reasons.

Wyss Institute. Guiren wang. Continuous liquid interface production of 3D objects. Additive manufacturing processes such as 3D printing use time-consuming, stepwise layer-by-layer approaches to object fabrication.

Continuous liquid interface production of 3D objects

We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers. Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part. We delineate critical control parameters and show that complex solid parts can be drawn out of the resin at rates of hundreds of millimeters per hour. These print speeds allow parts to be produced in minutes instead of hours. Although three-dimensional (3D) printing is now possible using relatively small and low-cost machines, it is still a fairly slow process. Science, this issue p. 1349. Chromaticity. Quantitative description[edit] In color science, the white point of an illuminant or of a display is a neutral reference characterized by a chromaticity; all other chromaticities may be defined in relation to this reference using polar coordinates.

Chromaticity

The hue is the angular component, and the purity is the radial component, normalized[clarification needed] by the maximum radius for that hue. The 3 things you should know about hashCode() In Java, every object has a method hashCode that is simple to understand but still it’s sometimes forgotten or misused.

The 3 things you should know about hashCode()

Here are three things to keep in mind to avoid the common pitfalls. An object’s hash code allows algorithms and data structures to put objects into compartments, just like letter types in a printer’s type case. The printer puts all “A” types into the compartment for “A”, and he looks for an “A” only in this one compartment. This simple system lets him find types much faster than searching in an unsorted drawer. That’s also the idea of hash-based collections, such as HashMap and HashSet. Source: Wikimedia Commons In order to make your class work properly with hash-based collections and other algorithms that rely on hash codes, all hashCode implementations must stick to a simple contract.

The hashCode contract The contract is explained in the hashCode method’s JavaDoc. Objects that are equal must have the same hash code within a running process 1. Axolotl embryonic development of heart. POSITIONS AVAILABLE. Three positions are open, all related to the same project.

A $32M, 5-year project funded by DARPA and the NIH was launched last summer with the aim of creating a game-changing paradigm for drug discovery and development. The project includes teams at MIT, Draper Laboratory, as well as tissue engineering/device/pharma/biotech companies, and is aimed at creating a platform that supports ten interacting micro-organ systems and associated sensors for assessing cellular responses to inflammatory cues and therapeutic interventions.
