Technology & Products

Key Products

VULCAN 600 and VULCAN 1200 industrial FDM printers (far-infrared heated chamber, dual independent hotends); X2Pro/X3Pro desktop-format industrial printers; SC12060 large-format closed-loop linear-motor printer; nationwide 3D printing/CNC hybrid manufacturing service network (创联三维)

Technological Advantage

Far-infrared rapid-heating chamber technology, direct-drive linear-motor motion system, in-house high-temperature sintering furnace for PEEK/high-performance polymer post-processing, and an integrated additive+subtractive (3D printing + CNC machining) manufacturing service model.

Differentiation

Value Proposition

Large-build-volume, far-infrared-heated industrial FDM printers with an open material platform, paired with nationwide 3D printing service centers, letting industrial customers move from prototyping to direct end-use part production.

How They Differentiate

Positions as an open, brand-agnostic material platform rather than a closed filament ecosystem, and bundles equipment sales with a nationwide 3D printing + CNC hybrid service network rather than selling hardware alone.

Market & Competition

Target Customers

Industrial manufacturers in automotive, aerospace/drone, robotics, medical device, defense and mold-making sectors needing large, high-temperature-capable end-use polymer parts.

Industry Verticals

Aerospace, Robotics, Drones/eVTOL, Automotive, Medical, Defense, Mold-making, Education

Competitors

Markforged; INTAMSYS; Raise3D (复志科技)

Growth & Milestones

Growth Metrics

Grew from a 2012 precision-machining startup into a multi-city operation with 7,000+ sqm Qingdao facility, R&D centers in Qingdao/Nanjing/Taiwan, and service centers in 6+ Chinese cities as of 2025-2026.

Major Milestones

2012: founded as Qingdao Inlong Electromechanical (precision parts); 2014: built dedicated Inlong Zhizao facility; 2017: National High-Tech Enterprise + Shandong 'Little Giant' certifications; 2020: began industrial nonmetal 3D printing R&D; 2024: SC12060 large-format printer mass production; 2025-07: merger with Taiwan's INFINITY3DP; 2025-09: Vulcan 600 far-infrared printer mass production; 2025-11: Shenzhen subsidiary opened; 2026-03: partnership with Western China Intelligent Connected Vehicle Innovation Center.
