Hangzhou-based metal 3D printing manufacturer Eplus3D has launched the EP-M3050, a metal powder bed fusion system that surpasses the long-standing three-meter barrier with a 3,050 x 3,050 mm build area, up to 256 lasers, and a five-meter Z-axis, making single-build production of industrial-scale metal components a commercial reality.
“Scaling metal PBF beyond three meters is not just about making the machine bigger. It requires solving airflow stability across a giant build chamber, managing fume and spatter during multi-day prints, and maintaining optical cleanliness at an unprecedented scale. Eplus3D has achieved all of this,” said a spokesperson from Eplus3D.
The EP-M3050 meets those challenges through a multi-laser architecture that ships standard with 100 lasers and scales to 256, achieving theoretical print speeds of up to 3,500 cm³/h. Crucially, the laser count is paired with coordinated scan strategies and real-time process control, ensuring that part quality holds across the entire build area, not just at its center.
The system also offers three build chamber configurations, square, cylindrical, and ring-shaped, allowing geometry to be matched to application. For ring-like or casing structures common in aerospace and energy, that adaptability directly reduces material waste.
From Proven Track Record to Unprecedented Scale
The EP-M3050 doesn’t arrive without precedent. Eplus3D has already placed over 100 units of its one-meter-class systems, the EP-M1250, EP-M1550, and EP-M2050, and more than 200 units of systems with at least one axis exceeding a meter.
That operational history in large-format metal printing provides the process knowledge base the EP-M3050 builds on. A 2.8m casing printed as a single integral component stands as the clearest demonstration of what the system can already deliver in practice.
Looking further ahead, the company states it can now custom-build metal PBF systems with volumes reaching 5m x 10m x 5m, a figure that repositions additive manufacturing as a credible alternative to conventional large-part fabrication methods in sectors like aerospace, oil and gas, and heavy industrial machinery.
