Machines and Printing Speed

Formnext 2023 showcased an impressive array of printing machines, catering to various sizes and preferences. Notably, exhibitors like BigRep and Hage3D grabbed attention with their expansive stands featuring large-format parts and machines, coinciding with their merger announcement. On the flip side, UpNano stood out by opting for micro-printing. Materials manufacturer Polymaker was also showcasing its high-speed filament range, PolySonic™ PLA, designed to meet these challenges.

What caught our eye this year was the resurgence of FDM desktop solutions, specifically those emphasizing higher print speeds. Users are evidently seeking rapid and repeatable models, making these desktop solutions a focal point at the event.

Furthermore, Stratasys introduced its cutting-edge industrial extrusion 3D printing solution, the F3330, setting a new standard in speed and reliability. With twice the speed of competing models, the F3330 boasts multiple extruders and a redesigned head movement mechanism, ensuring enhanced performance. Accompanied by a spacious print volume of 600 x 600 x 800 mm, this innovation signifies a significant leap forward in industrial 3D printing technology.

Artificial Intelligence 

The manufacturing industry’s, and indeed the world’s, focus on Artificial Intelligence found expression at Formnext. The increasing reliance on this concept by companies is notable, as it empowers machines to emulate human intelligence, leading to reduced manual intervention and labor costs.

One standout example is Automation Acoustics, an Australian company pioneering sensors designed to identify defects in 3D printing by analyzing the machine’s emitted sound. Leveraging seven years of research and data, the company has honed its expertise in interpreting manufacturing machine noises, with a current focus on DED and WAAM solutions.

On the software front, the PRINT&GO solution is worth mentioning, utilizing AI to identify printing errors and collect data on completed prints. The objective is to leverage this data for a deeper understanding of machine behavior, streamlining workflows, and enhancing overall productivity.

The Software Market

In the realm of Additive Manufacturing Software, Formnext highlighted a potential missed opportunity for major software conglomerates. Notably, there was a conspicuous absence of Dassault Systèmes and PTC, along with the limited presence of Hexagon and Autodesk. The maturing nature of Additive Manufacturing (AM) as a production technology, especially in critical industry applications, is giving rise to increasing digital challenges. Consequently, many Formnext visitors emphasized a significant focus on addressing these software challenges.

Given the deep entrenchment of companies like Dassault Systèmes in the value chain of enterprise manufacturers, facilitated through Computer-Aided Design (CAD), Product Lifecycle Management (PLM), and other associated toolsets, it was peculiar to observe this disconnect at Formnext. This is particularly noteworthy since many enterprises are actively seeking closer integration between these traditional platforms and the AM-specific software that drives 3D printing applications.

Integration was a regular topic at Formnext, but amidst a flurry of partnership announcements between hardware Original Equipment Manufacturers (OEMs) and software providers, there was a notable lack of tangible benefits for end-users. These corporate agreements might generate LinkedIn traffic, but if manufacturers cannot properly integrate toolsets, one must ask whether they are, in fact, self-serving partnerships rather than genuine creations of synergistic value for the end user.

Reinvention was a common theme in this space with 3yourmind showcasing their transitioning away from the Manufacturing Execution System (MES) space to instead concentrate on part validation. Meanwhile, there was significant interest at the AMFG booth, particularly in MAGICS integration and partner orchestration. With the additive manufacturers seeking deeper software integration and solutions to facilitate distributed manufacturing, these unique AMFG differentiators were a hot topic amongst visitors, particularly those with an ambition to scale their AM operations.

The University of Stuttgart’s GreenTeam, in collaboration with INTAMSYS, also left an impression with their 3D-printed, electric, self-driving racing car. These instances exemplify the unique applications and capabilities achievable through additive manufacturing (AM). While 3D printing stands out as a more sustainable alternative for crafting individual items, it’s crucial to scrutinize the ‘sustainability’ aspect of AM within the broader context of the automotive industry and mass production.

Formnext 2023 underscores the continued interest in additive manufacturing within the industry. Despite a tense geopolitical context with potential impacts on the market, there’s a dynamic and growth-oriented atmosphere. While some exhibitors scaled down their stands, others expanded, and new entrants placed their bets on the event. This marks a pivotal moment for the industry, and the upcoming months are poised to be decisive for numerous stakeholders.

“That’s the place to be to see the improvements in the AM market. Here at Formnext, we can explore and review all the various systems and materials efficiently in one place. That allows us to find and select the most suitable solutions for our production,” said Chip Gear, CEO of The Technology House.
