Q.Big 3D, a large-format additive manufacturing (LFAM) firm based in Aalen, has successfully completed its Series A funding round, raising €2 million. The round was spearheaded by 3D printing specialist, HZG Group. Global high-tech engineering firm Manz AG has supported the startup since its inception and continues to do so, with its founder, Dieter Manz, maintaining a personal stake in the company.

The new injection of capital coincides with Q.Big 3D’s unveiling of its Queen 1 large-format printer. The printer utilizes a patented technology developed by the university spin-off, which uses two nozzles seamlessly during the printing process. One nozzle facilitates rapid, high-volume printing while the other is used to create fine surfaces and structures. This system employs plastic granules, a readily available and time-honored base material.

Throughout Queen 1’s initial roll-out phase, which began in the fall of 2022, beta customers created large-scale components like rear light mounts, complex pipe flanges for the energy technology sector, and helicopter cockpit side doors. Q.Big 3D is now ramping up its sales efforts for the final product, which is slated for delivery by the end of the current year.

“In the field of additively manufactured large components, Q.Big 3D’s technology covers a very broad spectrum from prototypes, design, and functional samples to spare parts, operating equipment, and end products. We are thrilled by the potential range of applications because this is exactly where the classic advantages of 3D printing are effectively merged with a short and tool-less process chain to manufacture large components. We are excited about the next steps we will take together with the team and its Queen 1,” said Kerstin Herzog, founder and managing director of HZG Group.

“Compared to alternative processes such as milling, laminating, or casting, we enable a significantly shorter lead time for the production of components at a lower price. For example, one customer confirms a lead-time reduction of 70 percent and a cost reduction of at least 30 percent. With this customer feedback and HZG Group as an investor at our side, we are very confident about the market launch. Following the R&D phase, we are now set for growth,” said Katja Herrmann, co-founder of Q.Big 3D.

Large-scale becomes economical

A crucial step in additive manufacturing is the nozzle placement, as it’s challenging to maintain component precision during this process. Users typically had to choose between large components with rough surface structures and smaller ones with detailed structures. However, Q.Big 3D’s innovation, the VFGF (Variable Fused Granular Fabrication) process, allows for precise control of extruded plastic, depending on the part’s geometry.

Boasting an installation space of 1700 mm x 1100 mm x 1050 mm, and utilizing plastic pellets, the Queen 1 printer presents a cost-effective solution for various large-format 3D printing applications. Clients of Q.Big 3D include Voith, Kärcher, and John Deere. The technology holds significant potential in sectors like rail and commercial vehicle manufacturing, shipbuilding, aerospace, mechanical engineering, architecture, and construction, along with exhibition stand construction and building technology businesses.
