SHENZHEN, China — As the curtains closed on Formnext Asia Shenzhen 2026, Zongheng Additive Intelligent Technology (Zhuhai) Co., Ltd. walked away with something more valuable than leads: validation that its “industrial-grade quality at accessible prices” philosophy resonates with the market.
Held at the Shenzhen World Exhibition & Convention Center from August 26–28, the exhibition marked a significant milestone for the Zhuhai-based manufacturer, which brought three distinct machines to Hall 15 — each targeting a different segment of the additive manufacturing spectrum.
DM200: Precision Manufacturing in a Compact Package
The DM200 desktop DLP printer is engineered for industries where microns matter. With a 4K optical engine, 25-micron minimum layer thickness, and surface finish below Ra 0.8μm, the machine is purpose-built for dental applications, jewelry fabrication, and precision component production.
Measuring just 450×400×800mm, the bottom-up DLP system delivers a build volume of 192×108×120mm — a combination of footprint efficiency and print capacity that appeals to clinics, studios, and research labs alike. On-site demonstrations of dental models and intricate wax patterns gave visitors a firsthand look at the speed and uniformity that surface-light projection technology brings to high-precision workflows.
SLS 1518: Breaking the Price Barrier for Professional Nylon Printing
If one machine captured the crowd’s attention, it was the SLS 1518. This desktop SLS printer offers a 160×160×200mm build envelope at $13980 — a price point that repeatedly drew reactions of disbelief from attendees.
“FDM pricing with SLS capabilities” became a recurring phrase at the booth.
But the SLS 1518 is no stripped-down compromise. It features a 10W laser paired with an industrial-grade galvanometer scanner, achieving ±0.15mm accuracy and surface roughness as low as Ra 12μm. The system runs on a broad materials portfolio — PA11, PA12, TPU, and carbon-fiber-reinforced nylon — and leverages SLS’s signature support-free printing to handle complex internal channels and undercuts with ease.
For small-batch production runs, functional prototyping, and R&D applications, the SLS 1518 effectively lowers the barrier to entry for professional powder-bed fusion technology.
SLS3540Pro: High-Throughput Production, Uncompromised
At the other end of the spectrum sits the SLS 3540 Pro — a production-oriented system designed for scale. With a 350×350×400mm build volume and dual laser options (CO2 or fiber), the machine is built for continuous 24/7 operation.
The exhibit featured two striking demonstrations: an automotive air duct exceeding half a meter in length, and a densely packed build chamber loaded with hundreds of end-use parts. For service bureaus, automotive suppliers, and aerospace manufacturers, the SLS 3540 Pro offers a compelling total cost of ownership equation — particularly when factoring in its energy efficiency and material utilization rates.
Behind the Price: Full-Stack In-House Engineering
What enables Zongheng3D to deliver SLS performance at such competitive price points? The answer lies in vertical integration.
The company is one of China’s few manufacturers with in-house capabilities across SLS, SLA, and DLP technologies — including proprietary control boards, slicing software, and material formulations. Its first-generation integrated control board consolidates the computer, motion controller, and laser controller into a single unit, reducing system costs by over 50% through full domestic supply chain localization.
This approach extends beyond cost savings. By controlling the entire stack, Zongheng3D maintains tighter quality control, faster iteration cycles, and greater responsiveness to customer feedback — advantages that become increasingly critical as industrial 3D printing moves from prototyping to production.
