POOLP: Championing the Circular Economy with Urban Microfactories

Kicking off our journey through 2023’s innovative startups was the French company POOLP. Founded by two forward-thinking students from ENPC (École Nationale de Ponts et Chaussées), POOLP embarked on a mission to significantly expand the potential of additive manufacturing within the realms of art and architecture. Their early endeavors involved extensive experimentation with a diverse range of recycled and bio-based materials, striving to unlock their compatibility with 3D printing processes. This dedicated research led to the development of their proprietary solution, specifically engineered to make these sustainable materials suitable for additive manufacturing.

The culmination of their efforts is the innovative “urban microfactory,” a highly localized and sustainable production tool. This microfactory boasts the remarkable capability of valorizing local plastic waste, transforming it from an environmental burden into a valuable resource for additive manufacturing. POOLP’s 3D printing system utilizes large-format FGM (Fused Granulate Modeling) technology. Unlike traditional FDM printers that rely on plastic filaments, FGM technology processes plastic pellets directly. This approach not only facilitates the use of recycled materials but also enables the creation of a vast array of three-dimensional parts, often larger and more complex than those achievable with filament-based systems. Through this pioneering manufacturing system, the POOLP team is actively promoting the principles of the circular economy, advocating for an alternative philosophy of production and consumption that minimizes waste and maximizes resource utility. Their vision offers a compelling model for sustainable local manufacturing.

Spherecube: Advancing Sustainable Composite 3D Printing

Originating from an impactful project at the Università Politecnica delle Marche, Spherecube emerged as an innovative startup dedicated to making the 3D printing of composites more sustainable and efficient. Composites are highly valued in various industries for their superior strength-to-weight ratios, but their traditional manufacturing often involves complex processes and material waste. Spherecube addresses these challenges head-on with its groundbreaking laser thermal curing system. This advanced system, meticulously developed by their expert team, is capable of automatically creating high-performance composite products without the geometric constraints typically associated with conventional composite manufacturing methods.

At its core, Spherecube’s proprietary technology is built upon the precise extrusion of two distinct raw materials, each existing in a different physical state. The first is a thermosetting polymer matrix, provided in a viscous fluid state, which forms the foundational material of the composite. The second is the reinforcement material, presented in the form of fibers, which imbues the composite with its enhanced mechanical properties. The printhead itself is a marvel of engineering, specifically designed to efficiently and homogeneously mix the polymer matrix and the reinforcement fibers. This meticulous mixing process ensures perfect adhesion between both components during the critical manufacturing process, resulting in a composite material with optimal structural integrity and performance. With this cutting-edge technology, Spherecube is strategically targeting high-stakes industries such as aerospace, where lightweight yet robust materials are paramount; biomedical, for advanced prosthetics and implants; and sports and marine sectors, where durability and performance are key.

Axtra3D: Redefining Resin 3D Printing with Hybrid PhotoSynthesis (HPS)

In the dynamic and highly competitive field of resin 3D printing, two established technologies have long dominated: SLA (Stereolithography) and DLP (Digital Light Processing). Each possesses distinct advantages and disadvantages. SLA is renowned for its exceptional precision and ability to produce highly detailed parts, but it often sacrifices speed, leading to longer print times. Conversely, DLP technology offers significantly faster print speeds due to its ability to cure entire layers simultaneously, yet it frequently comes with limitations in terms of surface quality and resolution, especially across larger build platforms. Recognizing this inherent trade-off, the American startup Axtra3D has engineered a revolutionary solution to overcome these challenges and deliver the best of both worlds.

Axtra3D’s breakthrough is its proprietary Hybrid PhotoSynthesis (HPS) technology. This innovative process ingeniously combines the strengths of both SLA and DLP methods to guarantee unparalleled high resolution and surface finish on parts, all within a printing process that is significantly faster than traditional stereolithography. The core innovation lies in its machines, which integrate both a projector (for DLP-style area exposure) and a laser (for SLA-style precision tracing) simultaneously within a true coaxial optical system. This unique integration allows for the rapid curing of large areas with DLP, while the laser simultaneously refines contours and intricate details, ensuring superior part quality and accuracy. This advanced additive manufacturing method is therefore ideally suited for a wide variety of demanding industrial applications. These include high-precision prototyping in automotive and aerospace, rapid manufacturing of custom components, and highly detailed parts for healthcare and dentistry, where accuracy and biocompatibility are critical.

The ColdStream software then automatically optimizes the design, ensuring that the generated cooling structures are not only maximally efficient but also fully manufacturable within the specific constraints and capabilities of the selected 3D printing technology. This proactive approach eliminates design-for-manufacturing headaches and significantly accelerates product development cycles. To gain a comprehensive understanding of Diabatix and the transformative capabilities of the ColdStream platform, we encourage you to read the full interview with their team.

Gastronology: Revolutionizing Food for Dysphagia Patients with 3D Printing

Dysphagia is a prevalent and challenging medical condition that causes significant difficulty swallowing for millions of patients worldwide. This condition necessitates more time and considerable effort for the body to move food or liquids from the mouth to the stomach, often leading to malnutrition, dehydration, and a diminished quality of life. Traditional solutions for dysphagia patients typically involve pureed foods that, while easier to swallow, often lack visual appeal, natural flavor, and the original texture of the ingredients, transforming mealtime into a less enjoyable experience. The Dutch company Gastronology is tackling this critical issue by ingeniously employing 3D food printing technology.

Gastronology has developed a sophisticated additive manufacturing solution that allows food to be presented in its authentic, recognizable form. Their process begins with fresh puree, which serves as the base material. This puree is then expertly 3D printed to recreate the natural shape and appearance of the original food item, meticulously preserving its inherent smell and taste. Imagine a perfectly formed carrot, a visually appealing piece of broccoli, or a delightful chicken nugget, all crafted from smooth puree but retaining their distinct, appetizing forms. Gastronology’s products are designed for convenience and can be found frozen and pre-packaged, ready for consumption. The production involves a precise five-step process: starting with meticulous puree production, followed by advanced food 3D printing, then rapid shock freezing to lock in freshness, careful packaging, and finally, frozen storage for extended shelf life. Thanks to this innovative technology, Gastronology is transforming meals for dysphagia patients from a bland necessity into a moment of pleasure, replacing the currently existing tasteless and often unappetizing mixed options with visually appealing, flavorful, and dignified dining experiences.
