Following the crash of its earlier MIRA in May 2024, POLARIS refined the design and mounted two lighter aerospike engines manufactured by AM Global. MIRA II successfully completed a brief but significant three-second in-flight burn, solidifying what the company calls the first real-world demonstration of a linear aerospike engine.This design deviates from standard bell nozzles, potentially improving performance at varying altitudes. Although a small fuel leak led to the loss of a hatch during the flight, MIRA II landed safely, allowing POLARIS to gather performance data on low chamber pressure operations. The company plans further testing, culminating in a full-scale Aurora spaceplane by 2028.A digital rendering of POLARIS Spaceplanes future aerospike-powered vehicle.

Midrange and professional 3D printer shipments dipped significantly in early 2024, yet the entry-level segment costing less than $2,500 continued to grow, buoyed by demand for models from Bambu Lab and other Shenzhen-based manufacturers. Vice President of Global Analysis at CONTEXT, Chris Connery, cited cooling inflation and declining interest rates as drivers of renewed investment in 2025. Metal 3D printers, particularly laser powder bed fusion systems aimed at Chinese markets, are predicted to lead a 15% rebound in the industrial sector by the second half of next year.The CONTEXT logo. Image via CONTEXTInvestor activism continued at Nano Dimensions 2024 Annual General Meeting, where Murchinson Ltd. succeeded in removing CEO Yoav Stern from the Board, and terminating his role as CEO. Murchinson also removed board member Michael X. Garrett and installed two of its own nominees, intensifying the ongoing confrontation around Nano Dimensions strategy. Murchinson has repeatedly criticized Sterns expansionary tactics, notably proposed acquisitions of Desktop Metal and Markforged, labeling them overpriced.By the close of 2024, multiple court rulings had validated earlier Murchinson-led shareholder meetings that removed incumbent directors and pressed for a simpler de-classified board structure. While that measure failed to pass with the required 70% majority this month, Murchinson claims it achieved over 67% support, calling for the boards immediate cooperation. Ultimately, Nano Dimension now faces a scenario in which additional Murchinson nominees could further sway decisions on acquisitions and corporate direction.Yoav Stern (left) and Julien Lederman (right): Leadership transition at Nano Dimension.

The Geomagic brand includes Design X for reverse engineering, Control X for inspection, Freeform for intricate modeling, and more. In explaining the decision, CEO Jeffrey Graves stressed that the companys future growth lies in high-volume polymer and metal printing ecosystems driven by 3D Sprint, 3DXpert, and Oqtonplatforms integral to advanced digital workflows. While Geomagic has historically been recognized for scanning and mesh-processing solutions, 3D Systems expects the portfolio to flourish under Hexagon, a firm that sees 3D scanning and CAD bridging as essential to its design and simulation capabilities.Geomagic Design X software.

Led by two of its original co-founders plus a dedicated Eindhoven-based team, the company leveraged a profitable Dutch subsidiary and WVS International Inc. to preserve the Shapeways brand, production facility, and website. Because the trustee could not transfer user intellectual property, the marketplace structure from before is effectively gone.Shapeways has been reestablishing core functionalities: users can once again upload designs for printing on a professional production line, with an eye toward reactivating e-commerce integrations such as Etsy and Shopify. Days after this relaunch, Shapeways acquired the Thangs 3D sharing platform, which features over 24 million printable models and advanced IP scanning from Physna. By combining the new Thangs 3D Inc. with Shapeways digital manufacturing capacity, CEO Marleen Vogelaar believes the result should surpass the defunct Shapeways marketplace. Thangs will focus on consumer and creator needs, while Shapeways pivots toward professional and industrial solutions.The iconic Shapeways logo.
