LIA NEWS


continue with a session on the latest in additive equipment directly from major manufacturers, including Concept Laser and Optomec Design, followed by a session on new additive approaches from both academia and industry experts, such as wire-fed additive manufacturing that can produce features the size of a match head. Te first day will be capped by an excellent opportunity to network – the Exhibitor Happy Hour Reception. Te second day will address ‘bridging the


gap’ of laser additive manufacturing from research to application. Starting off, a keynote address by Professor David Bourell of Te University of Texas at Austin, director of the Laboratory for Freeform Fabrication, will discuss the current status of additive manufacturing. Te morning sessions will provide insights from government, corporate and academic labs and how they are taking innovations from the lab to the factory floor. In the aſternoon, the topics will shiſt to job shops and how they use additive manufacturing for their customers. Tis portion of the event will


hold particular interest for those who wish to start developing prototypes and even production parts using additive manufacturing processes, but do not know where to begin and are not ready to commit to purchasing equipment. Te workshop will close with the latest in process monitoring and control, two very important aspects to developing robust manufacturing processes. Peter Baker, LIA’s executive director, is


excited about this year’s workshop, stating: ‘Now in its eighth year, LAM has become a premier event in the additive manufacturing arena. We are grateful to the contributors and sponsors who create this valuable workshop.’ Of special note to those involved in medical


applications, LAM general chair Denney added: ‘While LAM 2016 does not specifically have a medical focus, those in this industry sector may find the workshop of interest. Technology in sessions on new processes, monitoring-control, research facilities and equipment advances may be of benefit to those in the healthcare arena. LAM 2016 also provides many networking

Introducing LIA’s new Desktop Evaluator software


Y


ou asked and LIA responded! Aſter the inception of the web-based laser safety hazard analysis system, Te Evaluator, LIA created an alternative platform of the


product – the Desktop Evaluator. Aſter the inception of the web-based Evaluator in 2010, LIA worked to create an alternative platform of the soſtware – the Desktop Evaluator – to further meet the specific needs of Laser Safety Officers (LSOs) in the field. Unlike the web-based


Evaluator, the Desktop Evaluator will be available for purchase on a USB drive, from which users can download the soſtware to their computer. Once it is stored on users’ PCs, LSOs will be able to perform a number of repeated calculations based on the ANSI Z136.1 American National Standard for Safe Use of Lasers – including maximum permissible exposure (MPE), optical density (OD), nominal ocular hazard distance (NOHD), nominal hazard zone (NHZ) and laser hazard classification – without worrying about

being connected to the internet. Tis feature will be especially beneficial for military users whose firewalls oſten restrict continuous access to online content. Te format of the Desktop Evaluator most


Evaluator users will be able to switch effortlessly between CW, single pulse, or repetitively pulsed lasers


Desktop


closely resembling the advanced subscription level of the web-based Evaluator, continues LIA’s tradition of offering users an easy and seamless experience. Te program’s accompanying user guide, located in the help menu, gives an overview of the program, from explanation of how to perform an evaluation to parameter descriptions and calculated results. Additionally, users can double-click any input parameters for an instant definition. Similar to the web-based


Evaluator, Desktop Evaluator users


will be able to switch effortlessly between CW, single pulse, or repetitively pulsed lasers, as well as adjust the beam profile (circular, elliptical or rectangular). Tis simplified format allows LSOs to record a number of variables in the leſt-side


panel – including wavelength, pulse width, focal length and more – yielding final calculations on the right-side panel. In addition, intermediate calculations will be displayed throughout the process. Te Desktop Evaluator also provides the classification of the laser and safety calculations for the eye and skin, including MPE, NOHD, NHZ, OD, specular NHZ and diffuse NHZ. Once these safety calculations are completed, users can either print the report or save the information to a file for later review. ‘Te Evaluator laser hazard analysis soſtware


will benefit LSOs or companies that work with sensitive or classified laser systems, where calculations must be kept within the control of the user,’ according to LIA’s education director, Gus Anibarro. ‘Tis soſtware is a standalone product, simple to use and simple to load on a computer. It will serve as a nice addition to the tools that a Laser Safety Officer needs for verifying hazard calculations.’l
