Development of acrylate-based material using a multivariable approach: additive manufacturing applications
March 03, 2015
FULL TEXT 1 Introduction Over the last several years, the application of additive manufacturing processes has been steadily growing because of the advantages provided by the type of processing. These rapid prototyping processes, such as stereolithography (SL), mask projection stereolithography (MPSL) technology, inkjet printing (IJP), scan-LED-technology (SLT) and simultaneous deposition and polymerisation (SDP), have been strongly affected by the development of UV-curable materials. Nevertheless, there still are several challenges to overcome to improve the mechanical properties of these materials ([10], [11], [12] Gibson et al. , 2002, 2010a, b; [33] Sangerano et al. , 2009; [5] Cunico, 2011; [18] Kolb et al. , 2011). In addition, several technologies, as such SDP and MPSL, tend to use the material based on methyl methacrylate and Trimethylolpropane triacrylate , in spite its shrinkage during polymerization ([12] Gibson et al. , 2010b; [5] Cunico, 2011; [6], [7] Cunico and Carvalho, 2011a, b; [17] Jariwala et al. , 2011). The main purpose of this work is to investigate the mechanical properties of a UV-curable acrylate material as a function of the tenor of material compounds. In addition, we performed an experimental optimisation to maximise the tensile strength, flexural stiffness and softening temperature and to minimise the time of polymerisation and viscosity.

Screen-free display formed using retro-reflector
March 02, 2015
SPIE has issued the following news release: Futuristic aerial, transparent, and floating displays appear in science fiction movies, for example, the image of Princess Leia in Star Wars. We've been able to create such a screen-free display using a retro-reflector. In theory, forming an aerial image requires light scattering or light emitting in the air. Thus, mist can be used as a scattering screen to form a real image. Laser plasma also has been used to form an aerial display without a screen.1 But mist and laser plasma are not convenient for general users. Purchase SPIE Field Guide to IlluminationWe have realized aerial LED signage using an easy (alignment-free), quick, and cost-effective imaging method. We realized that aerial displays will be explored for use in new fields of signage because they can be installed over roads without obstructing walking and traffic. For example, aerial displays enable traffic signs inside tunnels that do not interrupt airflow. Our approach forms an image of an LED panel in the air. The directivity of the image is sufficiently wide (well over 120 degrees), and it can be observed without an actual screen on the image plane.

Illumiseen LED Reflective Belt Encourages Exercise While Traveling
February 27, 2015
Everybody travels. Unfortunately for many people their normal routines get thrown out the window when they are not in their normal environment. People are often less inclined to exercise while traveling because they don#39;t have access to their usual equipment or gear they no longer have a familiar path to follow and they are sleeping at odd hours. In order to help combat this issueIllumiseen has developed an easy-to-pack LED reflective beltnbsp;that can be worn when exercising as a piece of familiar gear and to help keep visible in an unfamiliar neighborhood.nbsp; The Illumiseen LED reflective belt is both easily foldable and compact. It can fit into a backpack or luggage without taking up much space. This allow individuals to take the belt with them anywhere even while traveling. That way people can keep on exercising and keeping up with their normal routines during travel. The LED reflective belt helps to increase visibility when running or walking and wards off potential dangers. The belt is able to charge through a micro USB port which allows individuals to charge it on the go. It is sold in a variety of colors and offers two LED light modes; flashing or solid. The belt is suitable for both men and women as it is fully adjustable to suit a variety of sizes.nbsp;

Illumiseen LED Reflective Belt Prevents Bike Messenger Accidents
February 26, 2015
Being a bicycle messenger is tough. They face dangerous situations daily. Bicycle messengers must navigate through hazardous obstacles of cities each day. The obstacles include cars other bicyclists pedestrians debris animals and bad weather. Last year in New York City alone twenty-five cyclists were killed in a car collision. The majority of which happened at night and in bad weather. Bicycle messengers and regular cyclists should take the proper precautions to stay safe while biking at night. This includes remaining on well-lit streets mapping out a route wearing a helmet and dressing to be seen.nbsp;
