Formnext, the annual global additive manufacturing event, takes place in Frankfurt, Germany, from November 17 to 20, 2026. Nanjixiong has learned that Shandong Yinglong Zhilian Additive Technology Co., Ltd. (INLONG) will make its international debut there with large-format industrial FDM 3D printers equipped with a patented far-infrared heating system. Booth: Hall 12.1, E101.
For its first stop in Europe, INLONG is bringing machines ranging from a 1.2-meter platform to a desktop model. It will also invite visitors to try breaking sample parts by hand to demonstrate how the printers address weak Z-axis strength, warping and cracking in large parts.
When large-format FDM meets PEEK
Large parts made from high-performance materials such as PEEK and PEI remain difficult to produce as industrial FDM moves into end-use manufacturing. Low or uneven chamber temperatures and rapid cooling can cause severe warping, cracking and weak interlayer bonding. Conventional hot-air systems often take two to three hours to heat a large chamber to 150°C. They consume considerable energy and struggle to maintain a uniform temperature throughout the chamber.
Far-infrared production equipment.
INLONG has brought far-infrared heating into series production, redesigning the thermal environment of the printer. The company reports three benefits:
• Rapid heating: The chamber reaches 150°C in six minutes, with heating efficiency about 90% higher than conventional hot-air systems.
• Lower energy use: Energy consumption is reduced by about 50%.
• Stable temperature distribution: A three-layer insulation structure comparable to that of a sintering furnace holds the process temperature throughout the print and provides high-performance materials such as PEEK the conditions they need to crystallize. This reduces the risk of deformation from temperature differences.
Exhibition preview: industrial printers for three production settings
INLONG will show equipment for large parts, batch production and desktop industrial manufacturing.
1. Large-format heated chambers: Vulcan 600 and 1200
The Vulcan 600 has a 600 × 500 × 500 mm build volume, a nozzle temperature up to 525°C, a 150°C build plate, a print speed of 500 mm/s and throughput of 200 g/h. The Vulcan 1200 extends the build volume to 1,200 × 800 × 1,000 mm and reaches up to 650 g/h with a 1.2 mm nozzle. This allows extra-large structural parts to be printed in one piece, avoiding joining and related post-processing. Both printers support carbon- and glass-fiber-reinforced materials and can make functional end-use parts.
2. Shared features for continuous production
• Patented motorless quick-change dual printheads, with travel speeds up to 1,000 mm/s.
• Built-in four-spool drying cabinet that maintains humidity at or below 5% RH for continuous material supply.
• Inlong3D_OS supports remote monitoring and end-to-end data traceability. Automatic bed mesh calibration in the heated chamber and a thermal expansion compensation curve help maintain continuity and accuracy during long prints.
3. Desktop industrial manufacturing: X2 PRO
The X2 PRO offers a 300 × 300 × 260 mm build volume, a 400°C nozzle and a 150°C bed, with support for PPS, PPA and fiber-reinforced materials. It maintains a production speed of 300 mm/s and is designed for ready-to-use industrial performance in labs and small factories.
In-house manufacturing services
Industrial 3D printing services for high-performance fiber composites.
Six printing service centers in China and a Shanghai technical center
INLONG operates six printing service centers in Qingdao, Beijing, Nanjing, Shenzhen, Chongqing and Shijiazhuang around the clock. A Shanghai technical center provides pre-sales and after-sales support. The network provides local service across China's major manufacturing clusters.
INLONG combines 3D printing, precision CNC machining and sheet-metal fabrication in a single manufacturing service. It covers material selection, structural optimization, production and finishing, taking designs through to delivery of end-use parts.
Eight areas of application
Rapid prototyping, lightweight design, custom jigs and fixtures, batch orders, custom molds, large custom parts, component repair, and one-piece manufacture of complex structures.
One machine supports applications from prototypes to production and from repairs to one-piece builds. The patented active far-infrared heating system improves Z-axis strength, making high-performance engineering plastics suitable for end-use production.
Broad material compatibility
The machines support common filaments such as PLA, ABS, PC, PA, PP and TPU, and high-performance or carbon- and glass-fiber-reinforced filaments including PA6/12-CF, PA6/12-GF, PPS-CF, PPA-CF, PEI, PAEK and PEEK.
INLONG already provides rapid production services in Singapore, Japan and India. It plans to extend its network to Europe and North America.
Try breaking a part at the booth
Visitors can handle and try to break engineering samples to see the Z-axis strength of parts made in the far-infrared heated chamber. Anyone can try without an appointment or time restriction. Visitors who break a sample receive a souvenir. INLONG says seeing and handling parts is the most convincing way to judge material and equipment performance.
Nanjixiong's observations
Overseas brands have long held much of the process expertise and market influence in large industrial FDM printers capable of reliably processing PEEK and other specialty materials. INLONG is focusing on the underlying problem of thermal management.
Far-infrared heating addresses uneven temperatures in large-format 3D printing by replacing circulating hot air. Heating in six minutes and using 50% less energy would enable more frequent continuous production at lower cost. Combined with the six service centers in China, INLONG's offering spans equipment, materials, processes and manufacturing services.
