Printed Perforated Lampshades for Continuous Projective Images
From Haisen Zhao, Lin Lu, Yuan Wei, Dani Lischinski, Andrei Sharf, Daniel Cohen-Or, Baoquan Chen:
We present a technique for designing 3D-printed perforated lampshades, which project continuous grayscale images onto the surrounding walls. Given the geometry of the lampshade and a target grayscale image, our method computes a distribution of tiny holes over the shell, such that the combined footprints of the light emanating through the holes form the target image on a nearby diffuse surface. Our objective is to approximate the continuous tones and the spatial detail of the target image, to the extent possible within the constraints of the fabrication process.
To ensure structural integrity, there are lower bounds on the thickness of the shell, the radii of the holes, and the minimal distances between adjacent holes. Thus, the holes are realized as thin tubes distributed over the lampshade surface. The amount of light passing through a single tube may be controlled by the tube's radius and by its direction (tilt angle). The core of our technique thus consists of determining a suitable configuration of the tubes: their distribution across the relevant portion of the lampshade, as well as the parameters (radius, tilt angle) of each tube. This is achieved by computing a capacity-constrained Voronoi tessellation over a suitably defined density function, and embedding a tube inside the maximal inscribed circle of each tessellation cell. The density function for a particular target image is derived from a series of simulated images, each corresponding to a different uniform density tube pattern on the lampshade... (full paper)
Companies, employees not quite ready for cognitive technology wave of robotics, AI, machine learning
Larry Dignan for Between the Lines: Robots, artificial intelligence, machine learning and other cognitive technologies will replace about 7 percent of U.S. jobs by 2025 with office and administrative staff taking the biggest hit, according to a Forrester Research forecast.
The bad news is jobs will be lost. The good news is that new gigs will be created as cognitive technology takes hold. One reason the disruption won't be larger or happen sooner is that companies aren't ready for the change related to the new automated workforce, said Forrester.
Among the key items:
16 percent of U.S. jobs will be replaced, but 9 percent of jobs will be created. That's how Forrester gets to the 7 percent job loss by 2025 figure.
Emerging jobs will be robot monitoring pros, data scientists, automation specialists and content curators.
93 percent of automation technologists feel unprepared to take on smart machine technologies.
83 percent saw cognitive computing as critical to their companies' future.
32 percent of respondents said they are prepared for the cognitive technology changes ahead, but only 12 percent are prepared to deal with the human and organizational fallout.
46 percent say the number of jobs will remain about the same and 43 percent of respondents thought jobs would decline.

'UK manufacturers fail to understand Industry 4.0'
Ian Vallely for Works Management: There isn't enough understanding of Industry 4.0 by UK manufacturers, according to a report by BDO in partnership with the Institution of Mechanical Engineers. It said just 8% of UK manufacturers have a significant understanding of Industry 4.0 processes despite 59% recognising that the fourth industrial revolution will have a big impact on the sector, according to the report .
As the increasing use of automation, data exchange, technology and wider supply chain communications driven by Industry 4.0 provides both huge opportunities and threats to UK manufacturing, there remains a ‘gaping hole’ in the education and understanding of Industry 4.0.
According to the BDO Industry 4 0 Report, increased productivity, better data analysis, increased competitiveness and lower manufacturing costs are the top ways in which Industry 4.0 will affect UK manufacturing. Cont'd...

FIRST 3D TOOLS PRINTED ABOARD SPACE STATION
Evan Gough for UniverseToday: Astronauts aboard the International Space Station have manufactured their first tool using the 3D printer on board the station. This is another step in the ongoing process of testing and using additive manufacturing in space. The ability to build tools and replacement parts at the station is something NASA has been pursuing keenly.
The first tool printed was a simple wrench. This may not sound like ground-breaking stuff, unless you’ve ever been in the middle of a project only to find you’re missing a simple tool. A missing tool can stop any project in its tracks, and change everybody’s plans.
The benefits of manufacturing needed items in space are obvious. Up until now, every single item needed on the ISS had to be sent up via re-supply ship. That’s not a quick turnaround. Now, if a tool is lost or destroyed during normal use, a replacement can be quickly manufactured on-site. Cont'd...
Midea makes bid for robotics maker Kuka official
DW.com: Chinese appliance firm Midea has announced it has launched a cash offer for a stake of 30 percent in German industrial robotics supplier Kuka. The takeover bid has stoked controversy in Germany and Europe.
Midea said on Thursday it would offer 115 euros ($130) per share to Kuka owners under efforts to become the biggest single shareholder in one of the world's leading manufacturers of industrial robots.
The Chinese appliance maker, which is so far only known to be producing washing machines and air conditioners, also said its offer would end July 15, with no ceiling on the percentage of shares it was aiming to buy. Kuka shares closed at just above 106 euros in trading at the Frankfurt Stock Exchange on Wednesday. The stock gained about 26 percent since the deal was first proposed in May. Cont'd...

MIT Food Computers
From MIT: The Food Computer is a controlled-environment agriculture technology platform that uses robotic systems to control and monitor climate, energy, and plant growth inside of a specialized growing chamber. Climate variables such as carbon dioxide, air temperature, humidity, dissolved oxygen, potential hydrogen, electrical conductivity, and root-zone temperature are among the many conditions that can be controlled and monitored within the growing chamber. Operational energy, water, and mineral consumption are monitored (and adjusted) through electrical meters, flow sensors, and controllable chemical dosers throughout the growth period.
Each specific set of conditions can be thought of as a climate recipe, and each recipe produces unique results in the phenotypes of the plants. Plants grown under different conditions may vary in color, size, texture growth rate, yield, flavor, and nutrient density. Food Computers can even program biotic and abiotic stresses, such as an induced drought, to create desired plant-based expressions... (project homepage)

How Big Area Additive Manufacturing is Enabling Automotive Microfactories
Ian Wright for Engineering.com: Make no mistake, 3D printing is changing manufacturing.
Although it may take years before we see the full impact of bringing this technology from rapid prototyping to full-scale production, there are already hints of big things to come.
Take Local Motors’ recent purchase of two Big Area Additive Manufacturing (BAAM) systems from Cincinnati Incorporated (CI) as an example. The former company designs, builds and sells custom vehicles out of its US-based microfactories. The latter is a century-old manufacturer of metal fabrication tools and, more recently, BAAM.

Computational Hydrographic Printing
From Yizhong Zhang, Chunji Yin, Changxi Zheng, Kun Zhou's paper: Hydrographic printing is a well-known technique in industry for transferring color inks on a thin film to the surface of a manufactured 3D object. It enables high-quality coloring of object surfaces and works with a wide range of materials, but suffers from the inability to accurately register color texture to complex surface geometries. Thus, it is hardly usable by ordinary users with customized shapes and textures.
We present computational hydrographic printing, a new method that inherits the versatility of traditional hydrographic printing, while also enabling precise alignment of surface textures to possibly complex 3D surfaces. In particular, we propose the first computational model for simulating hydrographic printing process. This simulation enables us to compute a color image to feed into our hydrographic system for precise texture registration. We then build a physical hydrographic system upon off-the-shelf hardware, integrating virtual simulation, object calibration and controlled immersion. To overcome the difficulty of handling complex surfaces, we further extend our method to enable multiple immersions, each with a different object orientation, so the combined colors of individual immersions form a desired texture on the object surface. We validate the accuracy of our computational model through physical experiments, and demonstrate the efficacy and robustness of our system using a variety of objects with complex surface textures...

Carnegie Mellon Taps Private Gift for Engineering Simulation Center
Dian Schaffhauser for Campus Technology: Carnegie Mellon University has launched a new collaboration with Ansys, a global company that produces software for engineering simulation. Under the terms of the agreement, the company will endow a new "Ansys Career Development Chair" in the College of Engineering and help fund a new building dedicated to the study of Industry 4.0. That facility will bring together faculty, students, researchers and corporate participants.
Industry 4.0 is the name given to a movement that uses sensor, robotic, simulation and other innovative technologies to shrink development cycles and transform product design, development and manufacturing.
The new 30,000 square foot facility, which will be known as the Ansys Building, is intended to expand the "making" capabilities of the college by adding a simulation and collaboration lab and a large open bay facility for undergraduate students to build full-scale projects. That open bay facility will be next door to the fabrication and machining facilities of the Hamerschlag Hall MakerWing, announced in December, where students will be able to make their components and then assemble them into larger systems.
