Runnest (Shanghai Ruang) Showcases Ultrasonic AM Powder Handling Solutions at the 5th Additive Manufacturing Innovation Conference 2026
Cutting-edge inert gas-protected ultrasonic linear sieve & ultrasonic recoating system address core metal powder pain points for industrial 3D printing
Shanghai, China – July 16, 2026 Held in Ningbo, Zhejiang Province from July 15 to 17, the 5th Additive Manufacturing Innovation Conference 2026 gathered global AM scholars, enterprise leaders and full-chain practitioners to exchange insights on advanced AM materials, processing equipment and mass industrialization pathways. Shanghai Ruang Ultrasonic Equipment Co., Ltd. (Brand: Runnest) attended the summit with two flagship ultrasonic powder processing devices, demonstrating how ultrasonic technology revolutionizes metal powder sieving, recycling and uniform recoating workflows for additive manufacturing.
Core Challenges in Metal Additive Manufacturing Powder Processing
Metal powder bed fusion imposes stringent standards on powder particle size distribution, flowability, homogeneity and cleanliness. During repeated powder recycling, particles frequently agglomerate, oversized contaminants emerge, and powder flow performance degrades – all of which undermine recoating consistency and printing repeatability. To resolve these long-standing production bottlenecks, Runnest integrates proprietary ultrasonic vibration technology into two core AM auxiliary equipment lines, delivering full-process tailored powder handling solutions from powder recovery and precision classification to uniform layer recoating.
Exhibit 1: Explosion-Proof Inert Gas Protected Linear Sieve
Developed for reactive metal powders and high-purity material screening scenarios, this fully enclosed linear sieve supports customizable nitrogen/argon inert gas shielding systems to isolate powders from ambient air and prevent oxidation. Built-in ultrasonic high-frequency vibration superimposed on mesh surfaces rapidly disperses agglomerated particles, drastically reducing mesh blinding and powder adhesion. Qualified fine powder passes through screens efficiently while oversized debris and impurities are fully intercepted. Key equipment advantages:
Fully sealed structure to eliminate dust leakage and material loss
Configurable inert gas protection for titanium, aluminum and other oxidizable metal powders
Ultrasonic self-cleaning mesh to cut clogging frequency and boost continuous throughput
Linear conveying design shortens powder residence time inside the unit
Fully customizable layout, mesh grading and throughput based on material properties Primary applications: 3D printing metal powder recycling, new energy raw material classification, fine reactive metal powder processing and other high-cleanliness powder workflows.
Exhibit 2:
3D Printing Powder-Spreading Equipment
Uniform recoating is a decisive factor for stable metal 3D printing. Powder agglomeration, static adhesion and inconsistent flow easily cause uneven layer thickness and local powder accumulation, leading to printing defects. Runnest's dedicated ultrasonic Powder-Spreading Equipment integrates a matched ultrasonic vibration module calibrated to powder characteristics, recoater structure and machine operating parameters. High-frequency sonic energy loosens clustered powders, optimizing particle dispersion and flow distribution across the build plate. Functional improvements delivered by ultrasonic assistance:
Eliminates powder clumping and uneven local accumulation
Enhances overall powder dispersion uniformity
Achieves consistent layer thickness across continuous printing cycles
Stabilizes forming quality and reduces scrapped parts Unlike simple mechanical vibration retrofits, Runnest custom-tunes ultrasonic frequency, energy transmission and mounting positions to match each client’s powder and printer hardware, delivering production-ready recoating performance.
On-Site Technical Exchange & Industry Collaboration
At the conference booth, Runnest’s technical team held in-depth discussions with industry experts and visiting manufacturers covering inert gas screening, ultrasonic powder recycling and integrated recoating solutions. Attendees prioritized inquiries around four critical production pain points:
Efficient impurity removal post metal powder reuse
Closed-loop inert screening for oxidation-prone fine powders
Mitigation of agglomeration and mesh blinding in ultra-fine metal powder
Ultrasonic optimization to boost recoating uniformity
Seamless integration of screening equipment with existing 3D printing auxiliary lines
Runnest's specialists explained tailored equipment structures, mesh selection, ultrasonic system matching and full production line connection logic for different powder grades, particle sizes and throughput demands. The team emphasized that one-size-fits-all equipment cannot satisfy diverse AM powder characteristics; customized parameter calibration and pre-production material testing are essential to align hardware with on-site manufacturing processes.
