By demonstrating an entirely new – and significantly more efficient – approach to permit development, Senvol aims to generate tremendous value for the US Air Force, America Makes members, and the additive manufacturing industry as a whole,” said Zach Simkin, president of Senvol. .
“The results of this America Makes program have been incredibly successful. Additionally, we have identified several other areas of opportunity to deepen machine learning capabilities to address this critical industry need. We look forward to continuing to partner with the industry to advance this cutting-edge area. »
Conflux Introduces Quantify Quality Control Software
Speaking of software, Australian company Conflux Technology, well known for its 3D printed heat exchangers, has launched Conflux Quantify, proprietary quality control software developed specifically for the unique geometries required for its heat exchangers. Due to the resolution required of large data sets collected from whole heat exchangers or a series of parts, manual analysis of these sets is not possible; Conflux says its new software provides quantified analysis of large CT datasets.
Conflux uses proprietary Laser Powder Bed Fusion (LPBF) parameter sets that allow for otherwise impossible geometries, and the software analyzes and searches for defects in pore morphology and distribution, surface roughness and thickness of wall, in addition to other areas. It is also said to provide better quality control, cheaper HXs due to less trial and error, and improved development capabilities, leading to lighter/thinner/better performing HXs.
AddUp launches quality assurance software for dashboards
AddUp, a joint venture between French industrial groups Michelin and Fives, recently launched AddUp Dashboards, a new multi-scale monitoring software available for its FormUp Powder Bed Fusion (PBF) and BeAM Directed Energy Deposition (DED) machines. AM’s quality assurance software solution offers both historical processes and real-time data for your printers, regardless of location, and displays a summary on an easy-to-read dashboard. AddUp Dashboards receives data over MQTT and OPC-UA connections, which means it is compatible with all Industry 4.0 platforms.
AddUp Dashboards displays process data for 80 different parameters including powder consumption, gas flow status, oxygen and humidity levels, and more, and the information is updated at a rapid rate five seconds. By tracking data for each release, including the current release, users can get a good view of the progress and status of all their PBF and DED systems over the past month, or just watch to see the latest cycle overlay from the previous version, both of which help to monitor the health of the machine. The user interface only requires a web browser and can easily be customized with over 25 different data visualization styles. AddUp Dashboards also has an alert system. So if a printer’s condition gets out of control, email notifications can be sent to multiple users, or just one, so the issue is resolved in a timely manner.
Headmade Materials Finishes Series A Round
German 3D printing company Headmade Materials, which combines powder metallurgy with plastic 3D printing in its Cold Metal Fusion technology, announced the closing of a Series A funding round that raised approximately $2.5 million. euros; combined with previous funding rounds, the company’s total now stands at €8.25 million.

Photocentric technology used for a reusable name badge
Finally, UK badge maker Badgemaster used Photocentric LCD 3D printing to create a new reusable name badge for a major retailer. Originally, Badgemaster created a design with a plastic injection molded rear component, and a molding company was to tool and produce the badge, but the project was scrapped during the pandemic. Once it restarted, they ran out of time when the client requested a shorter timeframe to coincide with a rebrand launch. Badgemaster knew that Photocentric had built a 3D print farm to make face mask visor components for the NHS and care homes, and asked the company if they could deliver the product on time; after some product testing, the answer was determined to be yes. Badgemaster ordered 30,000 components to be delivered in three weeks and Photocentric printed them all on their LC Magna systems in Peterborough.
“We were delighted to assist Ian and the team at Badgemaster on this project where our print farm was able to provide a quick turnaround of components at the required quality, with no tooling required. Allowing our client to deliver for an important partner under a challenging deadline is a great example of the strengths of additive manufacturing as a solution, and it underscores the benefits of our 3D LCD technology,” said Sally Tipping, Sales Director at Photocentric.
