The first 3D startup to start 2023 was French company POOLP, which was created by two ENPC (École Nationale de Ponts et Chaussées) students who wanted to expand the potential of additive manufacturing in art and architecture. After experimenting with a multitude of recycled and bio-based materials, they developed their own solution to make them compatible with 3D printing. Thus arose the so-called urban microfactory, a production tool capable of valorizing local plastic waste and transforming it into material for additive manufacturing. The 3D printing system uses large-format FGM (Fused Granulate Modeling) technology, which uses plastic pellets instead of filaments to create all kinds of three-dimensional parts. With this manufacturing system, the POOLP team seeks to promote the circular economy, an alternative philosophy of production and consumption. You can find more information about this startup in the interview we conducted with its team.

Born from a Università Politecnica delle Marche project, Spherecube is an innovative startup working to make 3D printing of composites more sustainable. The laser thermal curing system, developed by its team, is able to create high-performance composite products automatically, and without geometric constraints. Specifically, Spherecube’s technology is based on the extrusion of two raw materials in different physical states. On the one hand, there is the thermosetting polymer matrix (in a viscous fluid state) and, on the other, the reinforcement material (in the form of fibers). In this way, the printhead has been designed to efficiently mix the matrix and the reinforcement, so that there is perfect adhesion of both during the manufacturing process. With this technology, the startup is targeting industries such as aerospace, biomedical, sports and marine. Learn more about Spherecube in this 3D startup interview from 2023.

In the field of resin 3D printing, two technologies stand out: SLA and DLP. The former is precise but slow, while the latter is much faster, but with great limitations in surface quality. The American startup Axtra3D has come up with a solution to this problem. The HPS (Hybrid PhotoSynthesis) technology developed by the company combines both methods to guarantee high resolution of parts in a much faster process than stereolithography. Specifically, its machines integrate a projector (DLP) and laser (SLA) simultaneously in a true coaxial system. Thus, this additive manufacturing method is ideal for applications in a wide variety of industries, including automotive, aerospace, prototyping, healthcare and dentistry, among others. Read more about HPS technology and the company’s upcoming plans HERE.

The Belgian startup Diabatix was created with the aim of helping companies with the design of their products to obtain proper cooling. To this end, it has developed ColdStream, a cloud-based platform that enables the use of generative design tools to provide better cooling of 3D printed parts. From thermal analysis to thermal design, the platform is based on state-of-the-art simulation methods without the need for additional software or hardware. In addition, something very interesting about the solution developed by Diabatix is that it adapts to the manufacturing method to be used later. That is, before starting the design process, the user will select the manufacturing technique of his preference, and the software will automatically optimize the design within the limits of the chosen technique. To learn more about the company and the ColdStream platform, read the full interview.

Dysphagia is a medical condition that causes difficulty swallowing in many patients. This causes the body to need more time and effort to move food or liquids from the mouth to the stomach. In order to make swallowing easier for those with this condition, Dutch company Gastronology has turned to 3D food printing. Specifically, it has developed an additive manufacturing solution that allows food to be presented in its original form, made from fresh puree, with its natural smell and designed with its original shape. Gastronology’s products can also be found frozen and packaged. This requires a five-step process: puree production, food 3D printing, shock freezing, packaging, and frozen storage. Thanks to this technology, the company manages to transform meals into a moment of pleasure, replacing the tasteless and mixed options that currently exist for patients with this condition. You can find out more about about this 2023 3D startup HERE.
