Well, it was only a matter of time before what happened last Friday happened. I’m talking about the Distributed Denial of Service (DDoS) incident on server farms of a key internet firm, Dyn, that repeatedly disrupted access to major websites and online services including Twitter, Netflix,GitHub, and PayPal across the U.S. and Europe last Friday. The White House called the disruption malicious and hacker groups have claimed responsibility, though their assertion is not yet verified.
The event involved multiple denial-of-service (DoS) attacks targeting systems operated by Domain Name System (DNS) provider, Dyn, that rendered major internet platforms and services unavailable to large swaths of North America and Europe.
“The complexity of the attacks is what is making it so difficult for us,” said Kyle York, Dyn’s chief strategy officer. “What they are actually doing is moving around the world with each attack.”
As a DNS provider, Dyn provides to end-users the service of mapping an Internet domain name—when, for instance, entered into a web browser—to its corresponding IP address. The DDoS attack involved tens of millions of DNS lookup requests from a large number of IP addresses. The activities are believed to involve a botnet coordinated through a large number of IoT devices that had been infected with the Mirai malware.
According to an article this week in Engadget, Apple reportedly plans to eliminate the USB 3.0 and Magsafe ports on its next-gen MacBook, and kill the 11-inch MacBook Air altogether. That’s according to Macotakara, the Japanese rumor site that was among the first to predict that the company would kill the traditional headphone jack on the iPhone 7. It also claims that Apple will unveil a 15.4- and 13.3-inch MacBook Pro at a new product launch event next week.
If the report is accurate, MacBook Pros will only have USB Type C and Thunderbolt 3 ports. As with the new MacBook, you’d presumably charge it through the USB-C port and connect peripherals via Thunderbolt 3. That means you’d need some kind of USB 3.0 adapter, since the majority of storage and other peripherals still use the traditional standard. For the MacBook, Apple sells a $79 USB-C dock that gives you USB 3.0, USB-C for power and an HDMI connection.
Are These Ports Gone In The New MacBook Pros?
The company will also release a new 13.3-inch MacBook Air, but discontinue the 11-inch model, according to the report. That squares with previous rumors that Apple would kill the smaller Air model, since it has been made effectively redundant by the 12-inch MacBook. However, it also shows that it isn’t discontinuing the MacBook Air completely, as some feared (including me).
When it comes to product manufacturing, consumers have zero tolerance for errors, and even less when it comes to vehicles. As we enter into a new generation of vehicle R&D with connected and autonomous cars, these expectations will only increase. What will this mean for automotive manufacturers and how will it change the traditional design and development processes?
Enter 3D modeling, simulation, and virtual reality (VR), things that Dassault Systemes knows something about.
Two announcements made recently by Groupe Renault and PSA Group demonstrate how Dassault Systèmes’ 3DEXPERIENCE platform is helping car companies to use several 3D technologies to design, create, and visualize innovative transportation products, including autonomous vehicles, to meet the demand of their customers with what it calls its Target Zero Defect platform.
Dassault Systemes’ Target Zero Defect Collaborative Platform
The transportation and mobility industries are continually impacted by broad social and economic trends. Concern for the environment is currently the top influencer. The push for improved fuel efficiency has received unprecedented attention, with government agencies worldwide imposing increasingly strict regulations. Environmental friendliness has also become a purchasing concern of consumers, who also demand the same web connectivity and entertainment options they experience at home and on their mobile devices. And then there’s connected/autonomous/driverless vehicles.
Dassault Systèmes is responding to these business and technical challenges with its Transportation and Mobility Industry Solution Experiences. The “Target Zero Defect” Experience builds upon the 3DEXPERIENCE platform with a series of industry-tailored process modules that empower users with the tools needed to address many industry concerns. For customers in the transportation and mobility industry these modules can help initiate the product development process flow using company-established knowledge and best practices that ensure and sustain competitive advantage. Through the full cycle of development from conceptual engineering to component design, manufacturing, and final assembly, the Dassault Systèmes industry process modules are designed to allow users to target zero defects in product delivery.
Target Zero Defect Modules Span the Automotive Product Lifecycle
For as long as I can remember, HP has produced an incredible range of products for science, engineering, and consumer customers. More recently the company has had a huge presence in computers and 2D printers.
Now, HP has vision for 3D printing for manufacturing parts on a relatively economical machine it calls the Multi Jet Fusion (MJF) 3D printer. The company claims these parts will have similar quality and characteristics as injection-molded parts, and will print at speeds that HP claims to be 10x compared to similar competing technologies. More about these claims to follow.
However, I have to wonder if HP will be able to fulfill its promise.
The HP Multi Jet Fusion Printer
HP wants to deliver SLS-quality parts on a system targeted at the professional 3D printer market. So-called professional 3D printers can be run in office environments and use photopolymers as material and inkjet printheads for material deposition. HP’s Multi Jet Fusion uses a printhead to jet a resin onto a powderbed where it will be fused.
In a Multi Jet Fusion technology white paper HP states, “Compared to SLS, HP Multi-Jet Fusion technology helps reduce the overall focused energy requirements needed to attain full fusing, resulting in more consistent material properties.” So SLS has higher “focused overall energy requirements,” yet the strong thermal bonds this energy creates is exactly what make SLS so desirable. So, exactly what is this process and can it really create material properties that match SLS and even injection-molded parts?

Historically, parts made from 3D printers, such as the MJF have lacked the robust mechanical properties of injection-molded parts. SLS is the only viable additive manufacturing technology capable of matching injection-molded parts in tensile strength and long-term stability. Materials undergoing the fusion process have issues that point to a natural limitation, not a technological oversight that HP or any other manufacturer can truly fix.
Last month at IMTS 2016 we checked out a lot of new and improved manufacturing technologies, including several innovative developments in 3D printing/additive manufacturing. A couple of the most unique technology introductions were from Stratasys.
The company demonstrated its next-generation manufacturing technologies as part of its Shaping What’s Next vision for manufacturing that builds on its industrial FDM 3D printing expertise in response to the needs of customers’ most challenging applications, addressing manufacturers’ needs to rapidly produce strong parts ranging in size from an automobile armrest to an entire aircraft interior panel.
Stratasys developed two new prototype machines that they called demonstrators to prove their practicality – the Infinite Build 3D Demonstrator and the Robotic Composite 3D Demonstrator.

The Infinite-Build 3D Demonstrator
The Stratasys Infinite-Build 3D Demonstrator was designed to address the requirements of aerospace, automotive and other industries for large, lightweight, thermoplastic parts with predictable mechanical properties. The 3D Demonstrator featured a new approach to FDM extrusion that increases throughput and repeatability. The system also employed a unique “infinite-build” approach, that prints on a vertical plane for parts that are virtually unlimited size in the build direction, such as entire airplane panels.
The Infinite-Build demonstrator is called that because, by flipping the vertical FDM process on its side, “We’re able to print parts in that vertical plane direction essentially as large as we want,” said Rich Garrity, president of Stratasys Americas.
