Studio 3e8 Launches $3,500 Desktop Metal 3D Printer Mesa 1: Powder Direct Extrusion + Built-in Sintering Solution

2026-11-01

On November 1, Somerville, Massachusetts-based Studio 3e8 announced the Mesa 1 desktop metal 3D printer with a built-in sintering furnace. It is scheduled to launch on Kickstarter on December 1, 2026, with a starting price of $3,500. The Mesa 1 uses a powder direct extrusion process that requires no laser or binder. After printing, there is no loose metal powder to clean up and no support structures to remove. Together with the built-in sintering furnace, it enables end-to-end metal part production, targeting makers and low-volume metal prototyping. Desktop metal printing has long been constrained by equipment cost and post-processing barriers. The Mesa 1's $3,500 price point challenges this status quo, and together with trends such as AI voice ordering in 'Vibe manufacturing,' it is lowering the barrier from idea to metal part. For powder companies, the growth of desktop metal printing will create demand for small-pack, multi-grade metal powders. Companies can get ahead by developing retail-level stainless steel and titanium alloy powder product lines.

Parts "Grown" in the Workshop: Three Afternoons Spent Beside an Additive Manufacturing Machine

In 2024, a front-line operator at an additive manufacturing workshop documented three consecutive afternoons of production on metal additive equipment: the recoater blade in the workshop lays each powder layer at roughly two-thirds the thickness of a human hair, about 60 to 70 microns, and a laser fuses the metal powder layer by layer along a preset path into a dense metal lattice; the resulting parts can withstand tens of MPa of pressure. Freshly removed parts are covered in titanium alloy powder as fine as flour and require sandblasting and surface grinding to meet installation surface requirements. The operator once printed a small aviation bracket; preheating, powder spreading and laser scanning took 14 hours in total, but a gap in the workshop's dust-proof door let powder humidity exceed the limit by 0.3 percentage points, causing insufficient interlayer bonding and accumulated internal stress at the bottom that warped the top layers, scrapping an entire batch of titanium powder. Workshop environmental controls require temperature fluctuations of no more than 2 degrees Celsius and no drafts, and personnel must stand in an electrostatic discharge area for half a minute before entering. Hard clumps left on the recoater blade create thin spots in the powder layer that the laser melts through during scanning, with no way to remedy the defect. The workshop replaced the traditional drilled angled holes with threaded plugs in hydraulic valve blocks with additively manufactured internal curved oil passages, reducing pressure loss. For conformal cooling channel inserts printed as a single piece, the channels run equidistant from the part's curved surface, cutting injection-molded part sink marks in half and raising the yield rate by 20 percent. The same operator compared a solid aluminum milled block of the same size with an additive part containing an internal grid-based lightweighting structure: fatigue test life was comparable, while the additive part weighed 40 percent less. However, for solid large parts such as half-ton machine tool bases, additive manufacturing costs four times more than conventional cast steel processing and takes twice as long, so these are still handled by foundries.

Multiscale Characterization Study on the Formation Mechanism of Lamellar Phases in Tungsten Heavy Alloys Fabricated by Laser Powder Bed Fusion

On November 1, 2026, the journal Materialia published a study titled "Hierarchical phase formation in tungsten heavy alloys fabricated via laser powder bed fusion," which systematically revealed the non-equilibrium solidification microstructural characteristics of 90W-7Ni-3Fe tungsten heavy alloy fabricated by laser powder bed fusion (LPBF) using multiscale characterization methods. SEM imaging showed position-dependent thermal gradient variations during the LPBF process. EBSD analysis indicated that the alloy exhibits a randomly oriented equiaxed grain structure with no preferred texture, an average grain size of approximately 10.75 μm, and an average geometrically necessary dislocation density of 3.06×10¹³ m⁻². Submicron γ precipitates and nanopores of approximately 100 nm were observed within W grains. Selected area electron diffraction confirmed the orientation relationship [011]W∥[001]γ between BCC W and FCC γ phases. TEM directly observed, for the first time, high-density dislocation pile-ups in LPBF tungsten heavy alloy and revealed nanoscale Fe₂W Laves phase precipitates in some matrix regions that had not been previously reported in conventional powder metallurgy processes. Although Fe₂W is generally regarded as a brittle phase, its presence as nanoscale precipitates is expected to strengthen the tungsten alloy through the Orowan mechanism. Tungsten heavy alloy (WHA) is a dual-phase composite composed of tungsten with elements such as nickel and iron, and is widely used in aircraft engine flywheels, rotors, counterweights, medical radiation shielding, and plasma-facing components of fusion reactors. Conventional powder metallurgy processes such as liquid-phase sintering are mature, while additive manufacturing has become an emerging alternative route owing to its near-net-shape capability for complex components. This study lays the foundation for establishing process–microstructure–property relationships for AM tungsten heavy alloys and for promoting microstructure-driven design.

Fourth National Metal Additive Manufacturing Technology and Application Exchange Conference Concludes in Hangzhou

Held in Hangzhou from October 30 to November 1, the Fourth National Metal Additive Manufacturing Technology and Application Exchange Conference was co-hosted by Hangzhou City University, University of Science and Technology Beijing, Central South University, Kunming University of Science and Technology, Nanjing University of Science and Technology, and the Ningbo Institute of Materials Technology and Engineering, CAS. Tang Huiping served as conference chair, with Qu Xuanhui, Zhou Kechao, Yi Jianhong, Liao Wenhe, and Pu Jibin as co-chairs. Among the four main topics, 'Powder Preparation for Metal Additive Manufacturing and Development of New Alloy Systems' ranked first, followed by AI-based structural design and process control, microstructure and properties, and technology applications. Plenary talks included Yi Jianhong's 'Research on Titanium Powder Preparation and Its Adaptation in LDED/BJ Forming Processes.' As China's annual academic conference on metal additive manufacturing, its agenda opens with 'powder preparation,' underscoring the upstream position of the powder segment in the industry's technology roadmap—a development worth the attention of powder companies tracking the latest alloy grades and process requirements emerging from academia.
