Ostberg, a leader in the Swedish HVAC industry, successfully achieved the integrated rapid manufacturing of large fan functional prototypes by adopting Creatbot Technology's D600 Pro 2HS industrial-grade dual-nozzle 3D printer. This reduced the traditional development cycle by 70% and costs by 65%, setting a new benchmark for the R&D process of complex industrial equipment. This case validates the core value of high-temperature large-format 3D printing technology in end-product development.
1. Customer Challenges: Pain Points in HVAC Equipment R&D
Company Background: Ostberg Group – a well-known European ventilation system manufacturer founded in 1947, with products covering commercial and residential fresh air systems, renowned for its energy-efficient technologies.
▲ Ventilation system manufacturer Ostberg
Core Requirements:
• Large Component Validation:
Need to create a 1:1 fan model for aerodynamic performance testing
• Material Performance under Extreme Conditions:
(1) Must withstand the impact of 80°C high-temperature airflow
(2) Structural strength to resist centrifugal tearing at impeller speeds > 2500 rpm
(3) Fatigue resistance: Pass high-frequency vibration tests lasting > 100 hours
• Realization of Complex Structures:
Integral molding of the impeller surface and air duct, which is difficult and time-consuming with traditional CNC machining
• Cost and Time Pressure:
The single-piece cost of metal mold trial production exceeds $8000, with a delivery cycle of ≥ 3 weeks
2. Solution: Empowered by D600 Pro2 HS Technology
Equipment Configuration: Creatbot Technology D600Pro2HS Industrial-grade 3D Printer
Core Features: Extra-large build volume of 600×600×600mm (Top 5% in the industry) | Dual 420°C high-temperature nozzles, supporting engineering materials such as ABS/ASA/UltraPA/PET-CF | High-precision industrial linear guides | Active constant-temperature chamber (70°C)
