3-D printing shapes building industry, creates rapid construction potential
A residential and commercial tower under development in Brooklyn that is changing the New York City skyline has its roots in research at the Department of Energy's Oak Ridge National Laboratory. The tower's white precast concrete façade rising from the waterfront site of the former Domino Sugar Factory evokes the form of a sugar crystal - a pattern created from 3D printed molds produced at DOE's Manufacturing Demonstration Facility at ORNL.
When Gate Precast, a member of Precast/Prestressed Concrete Institute (PCI), was awarded the façade of the Domino building, ORNL researchers saw the building's tower as the perfect platform to demonstrate that Big Area Additive Manufacturing, or BAAM, the technology could rapidly manufacture molds suitable for precast concrete manufacturing.

Georgia Number One state for Aerospace Manufacturing Coupled with Camden's Expertise in Space Industry

Spaceport Camden | October 15, 2020

Separate examinations from the consulting giant PwC and Georgia Southern University's Center for Business Analytics and Economic Research (CBAER) show the business appeal of Spaceport Camden. PwC's 2020 Aerospace producing allure rankings records the State of Georgia as the main state in the nation for aviation fabricating. As per the report, "[Georgia's Aerospace and Defense] workforce of 108,000 is utilized by in excess of 800 aviation organizations. Aviation items, esteemed at $10.8 billion, represent the state's top fares and speak to the second biggest assembling industry in the state, speaking to $57.5 billion in financial effect." Independently, a report by CBAER (PDF) at Georgia Southern University found that Camden County as of now represents 278 of Georgia's 926 direct space industry occupations. As per CBAER, "Camden County has an altogether more elevated level of specialization in the essential dispatch area than does the territory of Georgia… the expansion of a spaceport could help increment the work and wages effectively present here." Direct space industry net local item has expanded since 2008 for both Georgia and Camden County, while information shows statewide GRP has developed by 88% and in Camden County by 125%. The normal yearly wages per specialist in Camden County are $42,757, while the immediate space area normal wages are $150,190 in 2019. This implies that a run of the mill work in the space area wins 3.5 occasions the local standard. "Georgia is the number one state in which to do business, as well as the number one state for aerospace manufacturing. Coupled with Camden's existing expertise in the space industry, we are poised for massive growth with the approval of Spaceport Camden," said Steve Howard, Camden County administrator and Spaceport Camden project lead. Camden County authorities have recently promoted Spaceport Camden's capability to help progressing military from Naval Base Kings Bay and to utilize plane design specialists from Georgia Tech University, the country's biggest maker of architects. Camden County foresees an official conclusion on its Launch Site Operator's License Application by the Federal Aviation Administration (FAA) in the spring of 2021. About Spaceport Camden: Our Vision is to develop a successful world class spaceport through a public-private partnership that establishes Camden County as the Commercial Space Center of the United States. Our Mission is to create the premier spaceport strategically positioned to provide economic diversity with a competitive advantage for the space sector, Camden County, the State of Georgia and the United States of America.

Siemens Launches PCB flow, a Reliable, Cloud-Based Solution for Accelerating Printed Circuit Board Design-To-Manufacturing Handoff

Siemens | April 06, 2021

Siemens recently launched PCBflow, an innovative cloud-based software solution that connects the electronics design and manufacturing ecosystems. PCBflow enhances Siemens' XceleratorTM portfolio by offering a safe platform for printed circuit board (PCB) design teams to interact with a range of manufacturers, as well as by rapidly executing a variety of design-for-manufacturing (DFM) assessments in the context of each manufacturer's process capabilities, enabling customers to accelerate design-to-production handoff. PCBflow, which is powered by the industry-leading ValorTM NPI software engine and executes over 1000 DFM checks, allows PCB design teams to quickly detect manufacturability violations. These violations are then sorted and prioritized depending on the seriousness of the violation, directing users through photographs and locations on the design for quick detection and prompt correction. Siemens' first step toward online PCB assembly solutions that simplify the design-to-manufacturing handoff process is PCBflow. Siemens is the first company to deliver a marketplace featuring online, fully integrated DFM analysis technology, which can help refine projects, minimize front-end engineering cycles, and streamline designer/manufacturer interaction, with a leading role in the design-to-manufacturing flow. PCBflow simplifies client onboarding procedures for suppliers and offers designers a comprehensive source of experience, which will streamline customer/manufacturer cooperation. Furthermore, since manufacturers' capabilities are exchanged electronically, lengthy phone calls and email communications can be minimized, allowing real-time customer contact to concentrate more on the tactical, high-value conversation. PCBflow, as a software as a service (SaaS) technology, implements Siemens' software's strict security requirements, minimizing threats and defending intellectual property (IP) with no additional IT investment. PCBflow is compatible with MendixTM, a low-code application development platform. To realize the benefits of digital transformation more efficiently, the platform enables the creation of multi-experience apps and the sharing of data from any location, on any device, on any server, or platform. PCBflow was designed for ease of use and is accessible from almost any location, including smartphones and tablets. Additionally, PCBflow provides images, tool-tips, measurements, and exact positions of solderability errors and other PCB design violations to designers. For ease of sharing, reports are accessible online and in downloadable PDF format. PCBflow currently supports the ODB++TM language design file format, IPC 2581, with additional formats expected in 2021.
