This document discusses 3D printing and how it can empower youth. It is written by Deepak Mehta, who sees himself as an "alien" due to being an early adaptor of new technologies like 3D printing. He believes we are moving into a "post-digital" era where the physical and digital worlds merge through sensors and 3D printing. Mehta advocates teaching 3D printing skills to youth so they are not "boxed" in by old ways of thinking and can use new technologies to drive positive change.
The document discusses UV curing in 3D printing. It notes that UV curing uses photoinitiators and monomers that polymerize when exposed to light. This allows for high resolution printing techniques like stereolithography (SLA) and digital light processing (DLP). The decreasing costs of lasers and projectors will make UV curing more widespread and enable new materials. UV curing offers precise control over chemical reactions and will be a foundational technology for advanced 3D printing applications.

Water-based UV coatings cured with LED systems offer several advantages over mercury lamp systems, including being more environmentally friendly and allowing curing of heat-sensitive substrates. However, oxygen inhibition can reduce curing depth and conversion rates for some systems. Using phosphine oxide photoinitiators and minimizing oxygen penetration through physical drying of dispersions can help overcome this. New thiol-modified chemistries also show promise for oxygen inhibition-free curing and shadow area cure. Proper selection of photoinitiator and coating type are important to realize the full benefits of LED curing for water-based UV systems.
DLP, or Digital Light Processing, was invented in 1987 by Dr. Larry Hornbeck. It uses a Digital Micromirror Device (DMD) chip that contains a matrix of microscopic mirrors to create images by directing light. There are two main types of DLP systems - one chip uses a color wheel while three chip systems use a prism to separate colors. DLP has advantages over LCD like lower power consumption and maintenance. It finds applications in video projectors, 3D printing, and holographic storage due to its speed and ability to withstand mechanical stresses.
DLP (Digital Light Processing) technology was developed by Texas Instruments in 1987. It uses a digital micromirror device (DMD) chip containing a grid of hundreds of thousands of tiny tilting mirrors to produce high-quality images with high brightness and contrast. Each mirror represents one pixel and rapidly tilts between on and off positions to reflect light and produce colors using a spinning color wheel. DLP has advantages over other display technologies as it can create images of any size, has excellent brightness uniformity, and does not use heat-sensitive organic materials. It is widely used in projectors, TVs, and other applications demanding superior visuals.
UV LED - Technology, Manufacturing and Application Trends 2015 Report by Yole...Yole Developpement
Beyond simply replacing mercury lamps, UV LEDs are finding their way into new applications
NOW ESTABLISHED IN UV CURING, UV LEDS WILL FIND GROWTH OPPORTUNITIES IN DISINFECTION AND PURIFICATION AND NEW APPLICATIONS BY 2017 / 2018
Thanks to their compactness and low cost of ownership, UV LEDs continue to make their way in the booming UV curing business, through replacement of incumbent technologies such as mercury lamps. Thanks to this an overall UV LED market that represented only ~$20M in 2008 grew to~$90M in 2014, at a compound annual growth rate (CAGR) of 28.5%...
The document discusses and compares SLA (stereolithography) and DLP (digital light processing) 3D printing technologies. It summarizes that while SLA draws parts layer by layer slowly, DLP works faster by curing entire layers at once but results in pixelated surfaces. EnvisionTEC developed patented technologies including an Enhanced Resolution Module that shifts pixels by half and grayscaling that smooths surfaces. Tests found EnvisionTEC DLP produced parts with 96.3% accuracy compared to 68% for SLA, showing DLP can provide faster, more accurate and smoother surfaces than SLA.
UV LEDs - Technology, Manufacturing and Application Trends 2016 Report by Yol...Yole Developpement
After fast adoption of UVA LEDs for curing applications, UVC LEDs for purification/disinfection are now ready
FOLLOWING THE UV CURING BOOM, DISINFECTION AND PURIFICATION APPLICATIONS ARE FINALLY READY TO TAKE OFF
The UVC LED industry is still small but strong growth is expected in the next 18 months due to dramatic price reductions. In 2016 prices are 1/8-1/10 of what they were in 2015. This has been triggered by the industry’s development, its transition to mass production and improved device performance. With most of the industry believing that $1-$4/mW is the price that would trigger mass market adoption we are getting close to a UVC LED market boom. Another positive sign is that most UVC LED manufacturers are now focusing on developing cost-effective solutions rather than improving device power output. In parallel, the UVC LED industry continues to work on increasing lifetime and developing lower wavelength devices, below 280nm.
UVA LEDs continue to progress in the UV curing space. Continuous improvement of device performance coupled with price reduction has allowed the technology to be increasingly adopted in UV curing applications. Penetration of UV LEDs is increasing but we observe differences in adoption rates depending on application. Small size and low speed applications like spot adhesive and digital inkjets have the highest adoption rate, and most new developments use UV LEDs. This is due to the small module size and low irradiance level needed that limits the extra cost of integrating UV LEDs compared to the total price of systems like inkjet printers. On the other hand, applications that need high speed processes and/or high levels of irradiance such as screen printing or coating applications have lower adoption rates. This is because UV LED performance is not yet good enough to fully replace traditional mercury lamps.
In this context, we expect the UVC LED market to strongly grow from $7M in 2015 to $610M by 2021. Despite increased penetration rate in all applications, the UVA LED market will grow more slowly, from $107M in 2015 to $357M by 2021, moderated by price pressure.
The report presents a comprehensive review of all UV light applications including analysis of UV curing, UV purification/disinfection and analytical instruments. It highlights the UV LED working principle, market structure, UV LED market drivers and associated challenges, recent trends, new applications created by UV LEDs, UV LED market size split by application, and much more.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
