AconityONE

The AconityONE is a DMLS 3D printer from Aconity3D with a 400 x 400 x 400 mm build volume.

Specifications

Laser and Light Engine

AconityONE supports up to four independent single-mode fiber lasers, each 400–1,000 W (1,070 nm). Each laser can scan the entire 400×400 mm build area without restricted zones, unlike zone-based multi-laser systems. Configuration is flexible: 1, 2, 3, or 4 lasers depending on throughput requirements.

Optics / Scanner

One galvanometer scanner per laser with f-theta lens. Stitching algorithms for overlap zones are managed in AconitySTUDIO with configurable overlap width. The adjustable spot size (80–500 µm) inherited from AconityMIDI is available on all laser heads.

Platform

Square 400×400 mm build platform.

Calibration

4-Laser Stitching

Check each of the three stitching zones individually with a calibration plate. Cpk > 1.33 is the production requirement; verify with metallographic cross-section at each material change.

1,200°C Heating

IR thermographic map of platform at no-load heating. At 800°C+ allow 30+ min for stabilisation. At 1,200°C inspect ceramic coating for cracks before each build.

O₂ at Large Volume

Allow 15–25 min for chamber purging.

Common defects

Porosity in Stitching Zones (4-Laser Config)

Apply smooth overlap gradient in AconitySTUDIO; verify with metallographic cross-section at material changes.

Hot Cracking in Thick Superalloy Sections

Controlled post-build cooling 5°C/min via AconityOS; build orientation optimisation with Simufact Additive.

Delamination in Builds > 200 mm Z

Melt-pool monitoring after layer 100; support structures and optimised base attachment.

Density Variation at Laser Count Change.

What it is used for

Aerospace Turbine Components

400×400×400 mm + 4 lasers + 1,200°C preheat = unique combination for large turbine segments from superalloys, unachievable on standard LPBF platforms.

Nuclear Energy (W, Mo)

Refractory metals require 1,200°C preheat for crack-free builds: AconityONE is the leading platform in this niche.
