Manufacturers today increasingly demand large-scale 3D printers capable of producing full-size tooling and end-use parts in a single build. Industrial SLA (stereolithography) and SLM (selective laser melting) systems answer this need by scaling up build volumes without compromising accuracy. ChanhonTech’s portfolio includes such industrial systems – each a “3D printer big” enough for industrial-sized parts – that deliver on precision, productivity, and scalability. For example, ChanhonTech (an official Farsoon partner) offers the CHPro 800HD for large resin parts and the Farsoon FS1521M for large metal parts. Both machines bring advanced features to support high-throughput manufacturing. We examine each model’s technical highlights, build capacity, applications, and industrial advantages below.
CHPro 800HD (SLA): Large-Format Resin 3D Printing
The CHPro 800HD is a professional-grade SLA 3D printer designed for large-format resin parts. It features an 800 × 800 × 550 mm build envelope – large enough to produce one-piece molds, master models, or full-size prototypes without assembly. Inside its rigid steel frame, a high-power solid-state Nd:YVO₄ laser (UV) and ScanLab galvanometer system deliver fast, accurate curing. The optical system provides a variable beam diameter (~0.12–0.2 mm) with scanning speeds up to ~10 m/s, yielding rapid layer exposure over the entire build area. Layer thickness is as fine as 0.10 mm, and the machine achieves ±0.15 mm positioning accuracy (or ±0.15% on larger parts). In practice this means the CHPro 800HD can print complex geometries – including burn-out casting patterns and precision tooling prototypes – with smooth surfaces and tight tolerances. Its automated calibration, vacuum resin degassing, and closed-loop control ensure consistent high-quality prints. These features make the CHPro 800HD an ideal large-scale SLA printer for industries like aerospace, automotive, and footwear tooling, where high-detail, repeatable resin parts are required (for example, burnable master models and complex prototyping).
Key Features (CHPro 800HD):
Build Volume: 800 × 800 × 550 mm, enabling one-piece fabrication of industrial-sized parts.
Laser & Optics: High-power Nd:YVO₄ laser (355 nm) with galvanometer scanner. Variable beam (0.12–0.2 mm) yields fine detail.
Speed: Scanning up to ~10 m/s accelerates layer curing, improving throughput on large parts.
Resolution: 0.10 mm minimum layer thickness, ±0.15 mm accuracy on small features for smooth, dimensionally accurate builds.
Materials & Applications: Prints tough UV-curable engineering resins (including casting resins). Ideal for high-precision patterns, large prototypes, tooling masters and “investment casting” patterns used in aerospace molds or automotive prototypes.
Precision Surface: Provides high-precision, smooth-surfaced parts of any complexity, reducing post-processing.
These technical capabilities make the CHPro 800HD a precision, high-productivity SLA printer for large-scale manufacturing. Its large build envelope and fast, accurate scanning allow manufacturers to replace assembled tooling or multi-part molds with single-piece prints, shortening lead times and improving consistency.
FS1521M (SLM): Large-Scale Metal 3D Printing
The FS1521M is Farsoon’s flagship large-format metal powder-bed fusion (SLM) system, offered by ChanhonTech for industrial production. It delivers an enormous 1510× 1510 × 850 mm build Dmiension, enabling one-shot printing of very large metal components. The machine is configurable with up to 16 synchronized 500 W fiber lasers, dramatically boosting throughput for high-volume production. In practice the dual- or multi-laser system melts metal powder simultaneously over large areas, slashing build times while maintaining uniform material properties. Farsoon reports that the FS1521M was explicitly designed for large-scale, high-efficiency production in aerospace, automotive, and energy industries. Its massive build platform and optional circular/square build cartridges eliminate the need for welding or assembly of large parts, reducing costs and improving structural integrity.
The FS1521M’s advanced process controls ensure repeatable precision at scale. Integrated melt-pool monitoring, real-time thermal management and intelligent powder handling keep the build stable even under intensive multi-laser operation. The system can process engineering alloys (Titanium, Nickel superalloys, Maraging steels, etc.) to produce parts with excellent mechanical strength and heat resistance. Typical applications include aerospace engine or airframe components (e.g. Ti parts), automotive structural and powertrain parts, and energy/industrial components like turbine blades or heat exchangers. Farsoon notes that FS1521M systems have been used globally for large titanium engine parts and copper alloy thermal systems. In these fields, the ability to print big, complex metal parts in one go—with ten- to hundreds-of-laser-level productivity—translates to higher throughput and new design freedom for manufacturers.
Key Features (FS1521M):
Build Envelope: Extremely large (up to 1510 × 1510 × 850 mm), so the largest metal parts (e.g. a 1.45 m diameter panel) fit in a single build.
Multi-Laser Productivity: Configurable with 16 or 32 fiber lasers (500 W each). Synchronized lasers dramatically increase melt rate and throughput while preserving accuracy over the whole large area.
Process Control: Real-time monitoring, optimized thermal management and intelligent powder mixers/conveyors ensure stable builds and high material utilization.
Industrial Design: Fully enclosed, high-energy optics and safety systems. Optional build cartridges (square or circular) and alloy mixers support continuous, unmanned operation.
Materials: Capable of printing high-strength alloys (Ti-6Al-4V, Inconel 718, maraging steel, etc.) with uniform microstructure.
Applications: Suited for aerospace (titanium engine/structure parts), automotive (engine blocks, frames), and energy/heavy industry (large heat exchanger manifolds, turbine components). The FS1521M delivers series-production precision for large metal parts, enabling lighter, consolidated components and faster time-to-market.
By combining enormous build volume with multi-laser speed and robust controls, the FS1521M offers high productivity and scalability for metal additive manufacturing. As one industry review notes, Farsoon’s large-format machines (like the FS1521M) are enabling “large-scale printing for complex, monolithic parts” in sectors from aerospace to space/rockets. In practice, users get precise, repeatable builds of heavy-duty parts in materials that meet demanding specifications.
Precision, Productivity and Scalability
Both the CHPro 800HD (SLA) and FS1521M (SLM) exemplify how modern large-scale 3D printers combine precision with high throughput. Their large build volumes eliminate secondary assembly of components, while high-speed lasers and advanced controls maintain fine detail across big parts. This means manufacturers can achieve production-grade accuracy and surface finish at far larger scales than desktop systems allow. For example, the CHPro 800HD produces fine resin features (±0.15 mm accuracy) on parts nearly a meter wide, and the FS1521M can print full-scale aerospace components with synchronized lasers maintaining uniform part quality. In both cases, the result is faster cycles and lower per-part cost in high-end prototyping or low-volume production.
In summary, ChanHonTech’s large-scale 3D printers – from the CHPro 800HD SLA system to the Farsoon FS1521M metal system – deliver the precision, throughput, and scale that industrial manufacturers need. Each machine’s combination of precision optics or lasers, massive build volume, and automation supports complex part geometry, tight tolerances, and year-round productivity. Manufacturers are encouraged to explore these industrial 3D printing solutions on ChanhonTech’s website, where detailed specifications and support resources are available. By investing in a truly large-scale 3D printer, companies can accelerate innovation and production for next-generation products in aerospace, automotive, energy and beyond.
