Although we recently reported that carbon fiber 3D printing is still in its early stages, we also understand that the development of this field is advancing rapidly. After learning that an Idaho-based company was using an industrial robotic arm for continuous fiber additive manufacturing (AM), we met a Dutch company, CEADgroup, which is deploying large-scale continuous carbon fiber 3D printing.
Prior to the establishment of CEADgroup in 2014, Janssen was the co-founder of Leapfrog 3D Printer, which later became a well-known manufacturer of desktop 3D printers in the Netherlands. However, for Janssen and Leapfrog co-founder Maarten Logtenberg, the consumer market limits AM's ability to innovate, which is why they set up a new company dedicated to making machines for businesses.
The two wanted to combine Jansen's background in industrial design with Rogenberg's background in mechanical engineering, which led to the formation of CEAD, an acronym for "combination of engineering and design". They began manufacturing industrial manufacturing equipment for their customers, including customized CNC machine tools and automated production lines. It wasn't until 2017 that they decided to narrow the focus to 3D printers.
In order to adapt a technology to industrial production, the founders of CEAD began to discuss their needs with potential customers. They found four important criteria:
Size: In order to produce end parts for industrial use, it needs to be greatly expanded from a desktop 3D printer.
Speed: Parts need to be manufactured quickly, especially when they are large.
Strength: Industrial components are subject to a large amount of load and must be sufficiently strong to handle it.
Reliability: The system must be able to perform predictable, high-quality 24/7 work.
To meet these standards, CEAD has developed Continuous Fiber Additive Manufacturing (CFAM), which can print 3D-printed parts up to 4 m x 2m x 1.5m at a speed of 15 kg per hour. To make these components strong enough, the company turned to composites, especially glass and carbon fiber-reinforced materials. It's worth noting that CEAD hasn't disclosed how it's incorporating continuous fiberinto into print at such a fast pace, and until then, there's reason to wonder how it did it. Finally, they combine their expertise with the tools and materials they deem appropriate, such as Siemens' servo motors and control software, for reliability.

Having a kitchen rack blender is a must for home cooking: strong, smooth and ancestral, so many people don't have to beat and knead. But what about a lot of accessories? There are so many, they promise to increase the versatility of your machine. What are the money and cabinet spaces that are really worth it?
To find out, I tried them all out in my beloved vertical blender in the kitchen at home. When they don't want to do too much, attachments are often the best - in most cases, the more direct the task, the better. I rate each attachment based on its versatility (single-use, multitasking, or special interest), price, and overall functionality. There are bad, there are ugly, but mostly great. Here's an outline of my tests, from the ones that are the most worth testing to the least worth testing.
Our daily lives are characterized by information and availability from central sources. Messages are collected, centrally processed, and distributed locally. In many cases, our electricity, water, natural gas and telecommunications networks are centralized, as are wastewater treatment systems. Individual networks can be organized by region or country. In each case, several users in the network are grouped together on a single supply unit.
In vacuum technology, the concentration of vacuum pumps has been used for decades. Vacuum systems are most widely used in packaging applications.

When multiple production lines are running in parallel, it is useful to use concentrated vacuum equipment for extrudering the extrusion of the extruder. Extrusion is the removal of gas from polymer melts in the extruder to remove volatile substances, thus ensuring consistently high product quality. In this process, a similar process is combined and supplied by a central vacuum system. In profile production, PVC melts are degassed using a central vacuum system, and in the compounding process, they are used to degass the polymer melt. In addition, the central vacuum power supply can be used for the calibration tank of profile extrusion.
In addition to demand-driven energy consumption, the main advantage of the central vacuum unit is that it reduces installation work. The central system described below is based on an air-cooled claw vacuum pump that does not require any workflow.
