3DPOD 320: HeyGears CEO'su, Peiyan Gui

Key Takeaways

• HeyGears, founded by Pei-yan Gui, evolved from a desktop vat-polymerization pioneer to a dental-system specialist, and now to a full-color UV desktop 3D printer.
• The company’s latest model, the HeyGears ColorJet 320, delivers a 120 mm × 120 mm × 150 mm build volume, 50 µm XY resolution, and 10-color CMYK+white printing in a single pass.
• Engineering rigor (±0.05 mm dimensional accuracy) and aggressive pricing (~US$2,499) position the printer as a disruptive alternative to traditional monochrome SLA machines.
• HeyGears leverages a vertically integrated supply chain in Shenzhen, allowing rapid firmware updates, a 2-year warranty, and a global dealer network.
• The shift to desktop UV color printing is expected to accelerate adoption in dental labs, jewelry, and low-volume consumer product prototyping.

HeyGears: From Polymerization Roots to Full-Color Desktop Printing

Founder’s Journey

Pei-yan Gui, a U.S.-educated engineer, co-founded HeyGears after returning to China in 2015. The first generation of HeyGears machines were desktop vat polymerization (SLA) systems targeting hobbyists and small workshops. Early specs included a 50 mm × 50 mm × 70 mm build envelope, 75 µm XY resolution, and a price point of US$799.

Strategic Pivot to Dental Applications

In 2018, HeyGears recognized the growing demand for high-precision dental models. The company introduced the DentalPro 210, a 100 mm × 100 mm × 120 mm printer capable of 25 µm resolution and biocompatible resin processing. Sales rose to ≈ 12,000 units within two years, accounting for 68 % of the company’s revenue.

The Current Leap: Full-Color Desktop UV Printing

The latest offering, the HeyGears ColorJet 320, combines the compact footprint of a desktop unit with industrial-grade color capability:

Engineering Edge

HeyGears’ in-house laser-modulated LED array delivers uniform exposure across the vat, reducing cure-depth variance by 30 % compared to conventional point-laser SLA. The printer’s closed-loop temperature control maintains the resin bath at 23 ± 0.2 °C, ensuring repeatable viscosity and minimizing warpage.

Market Reception

Since its launch in March 2024, the ColorJet 320 has secured ≈ 1,800 pre-orders across Europe, North America, and Asia. Early adopters cite:

• Dental labs: ability to print multi-shade prosthetics without post-painting.
• Jewelry designers: direct color casting reduces material waste by up to 40 %.
• Product developers: rapid visual mock-ups accelerate design reviews.

Business Model & Future Roadmap

HeyGears maintains vertical integration—from resin formulation to firmware development—allowing a 4-week lead time for hardware upgrades. The company plans to release a high-throughput 500 mm³ variant (ColorJet 500) by Q4 2025, targeting small-batch manufacturing.

Implications for the Desktop 3D Printing Landscape

The emergence of a full-color, engineering-focused desktop printer challenges the long-standing dominance of monochrome SLA platforms. By delivering comparable build volumes and superior color fidelity at a competitive price, HeyGears narrows the gap between prototyping and low-volume production. Industries that previously relied on post-process painting or multi-step casting can now consolidate steps, reducing lead times by 20-30 %.

Bottom Line

HeyGears, under the leadership of Pei-yan Gui, has turned a series of strategic pivots into a compelling value proposition: a desktop UV printer that marries industrial accuracy with true color output. The ColorJet 320’s technical specs—50 µm resolution, ±0.05 mm accuracy, and a 10-color palette—set a new benchmark for desktop additive manufacturing. As the market embraces on-demand, multi-material production, HeyGears is poised to become a reference point for engineers seeking a versatile, cost-effective solution without sacrificing performance.
