The AconityMIDI is a DMLS 3D printer from Aconity3D with a 170 x 170 x 200 mm build volume.

Specifications

Laser and Light Engine

The AconityMIDI uses a single-mode 400 W fiber laser (1,070 nm Yb:YAG) with a Gaussian beam profile. The laser spot diameter is adjustable on-the-fly from 80 to 500 µm: a unique feature enabling fine contouring and fast bulk fill within the same layer pass.

Optics / Scanner

Galvanometer scanners with an f-theta lens. The system supports tilt-scan strategies and off-axis positional corrections to compensate for thermal drift at 1,200°C platform temperatures.

Platform

Cylindrical build chamber Ø170×200 mm (reducible to Ø55 mm for expensive powders). Active platform heating to 1,200°C: the highest preheating temperature in commercial LPBF.

Calibration

Spot Calibration

Verify focal position with thermal-sensitive paper at each material change. Gaussian deviation must not exceed 5% of nominal spot diameter.

Platform Heating

Check temperature profile with thermocouples or pyrometer during ramp-up. At 1,200°C allow 30 min thermal stabilisation before build start.

Atmosphere

O₂ < 10 ppm for refractory metals; < 50 ppm for Ti; < 500 ppm for steels. Use argon 6.0 for W/Mo.

Small Cylinder (Ø55 mm).

Common defects

Porosity (Keyhole / Lack of Fusion)

Distinguished by CT: spherical pores = keyhole; irregular = lack of fusion. Run a 5×5 power/speed DoE matrix for every new alloy due to the wide spot-size range.

Oxide Inclusions in Refractory Metals

WO₃ and MoO₃ are volatile and contaminate the chamber above O₂ > 10 ppm. Perform helium leak test before every refractory build series.

Hot Cracking in γ'/γ'' Ni Superalloys.

What it is used for

Academic LPBF Research

Full parameter access plus small Ø55 mm cylinder makes AconityMIDI the ideal platform for alloy development with minimal powder investment.

Refractory Metals (W, Mo, Ta)

1,200°C preheat is a prerequisite for crack-free tungsten builds. No other LPBF platform in this price class offers this capability.

Biomedical Ti/Zr Implants.
