VENOX Systems

The Austrian startup VENOX Systems has introduced a truly remarkable 3D printer that is pushing the boundaries of what FDM technology can achieve. This innovative machine is not only capable of printing on five axes, offering unprecedented geometric freedom, but also features an advanced head-changing system that allows for the integration of six different tools. These versatile tools include various FDM printheads for standard thermoplastics, but more importantly, the company’s exclusive CFFP (Collision-Free Fiber Placement) processes designed for continuous fiber printing. Co-founder Nicolai Wampl highlighted that the company was specifically established to address a critical limitation of traditional FDM/FFF printing: the inherent issues with part strength, particularly along the Z-axis. He explained that conventional 3-axis printers can only reinforce parts at a planar level, which often results in significantly low Z-axis strength, limiting the functional applications of FDM parts. The V-REX printer, with its advanced 5-axis capabilities, overcomes this limitation by enabling fibers to be precisely aligned along the part’s actual load path. This intelligent fiber placement dramatically improves the part’s overall durability, anisotropic strength, and structural integrity, making it suitable for more demanding applications.

sallea

While 3D printed meat and fish products have garnered attention, the innovative startup sallea is taking a remarkably unique and indirect approach to food fabrication. Instead of directly 3D printing the alternative meat or fish products themselves, sallea focuses on creating intricate 3D scaffolding. This ingenious method provides non-printable materials with access to complex 3D structures and geometries that would otherwise be impossible to achieve. Their process involves printing templates using common salt, which is then encased with materials that are typically difficult to print or can only be printed in low resolution, such as plant proteins and polysaccharides crucial for cellular agriculture. Once the desired structure is formed, the salt template is dissolved, leaving behind the cast material in the precise and complex geometry initially designed. While the company’s primary focus currently lies in food applications, particularly in creating structured alternatives for cultured meat and fish, the underlying technology holds immense potential for other materials like thermoplastics. By offering an indirect, yet highly effective, method for cellular agriculture, sallea is directly addressing current challenges associated with bioprinting and the creation of textured, complex food products. Their innovative technique could unlock significant advancements in sustainable food production and materials science.
