Design automation is highly beneficial to such industries that develop products which although look the same, have the provision of customization for specific customer requirements.
Raspberry Pi serves as the main controller board for the setup, capturing the images using the Pi Camera, controlling the Line LASER diode and providing control signals to the EasyDriver (Stepper Motor Driver).
By monitoring your printers to ensure they are working correctly you can reduce costs but having the ability to isolate your 3D printer or extra machinery after it has completed the task adds extra cost savings.
From OpenKnit: OpenKnit is an open-source, low cost, digital fabrication tool that affords the user the opportunity to create her/his own bespoke clothing from digital files. Starting from the raw material, the yarn, and straight to its end use, a sweater for example, in about an hour. Designing and producing clothes digitally and wearing them can now happen in the very same place, rewarding the user with the ability to make decisions regarding creativity and responsibility.

Dave Sutton for IT Pro Portal: A technical evolution has taken place, which has made cyberthreats more potent than at any other time in our history. According to PricewaterhouseCoopers, over half of British businesses will suffer cyberattacks by 2018. As businesses seek to embrace Industry 4.0, cybersecurity protection must be a top priority for Industrial Control Systems (ICS). These attacks are financially crippling, reduce production and business innovation, and cost lives. In years gone by, legacy ICS were developed with proprietary technology and were isolated from the outside world, so physical perimeter security was deemed adequate and cybersecurity was not relevant. However, today the rise of digital manufacturing means many control systems use open or standardised technologies to both reduce costs and improve performance, employing direct communications between control and business systems. Companies must now be proactive to secure their systems online as well as offline. Cont'd...
The 3D printing field is expected to grow more than 14% annually to become an $8.4 billion industry by 2020
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)
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)
The additive excavator cab design competition had very few limitations on the cab design and essentially encouraged students to showcase our skills and ideas. We could create something totally unique, aesthetically pleasing, yet functional to showcase the capabilities of additive manufacturing
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...

Understanding Permanent Marks and Methods for UDI Marking and Verification
Why is accessible 3D printing so beneficial for first-time entrepreneurs? Read on for some answers.
Shalini Saxena for ArsTechnica: Customizable, wearable electronics open the door to things like heart-monitoring t-shirts and health-tracking bracelets. But placing the needed wiring in a complex 3D architecture has been hard to do cheaply. Existing approaches are limited by material requirements and, in the case of 3D writing, slow printing speeds. Recently, a research team at Harvard University developed a new method to rapidly 3D print free-standing, highly conductive, ductile metallic wires. The new method combines 3D printing with focused infrared lasers that quickly anneal the printed nanoparticles into the desired architecture. The result is a wire with an electrical conductivity that approaches that of bulk silver. Cont'd...
