Sinterit SUZY

The Sinterit SUZY is an SLS 3D printer from Sinterit with a 130 x 180 x 330 mm build volume.

Specifications

Light Engine: 30W infrared fiber-coupled diode laser with >30,000-hour rated service life: significantly longer than CO₂ tubes in competing systems (typically 5,000–10,000 h).

Optics/Scanner: Galvanometer scanner optimised for speeds up to 20 mm/h on Z-axis: 35% faster than previous Sinterit models.

Platform: 130×180×330 mm sintering platform: identical to Lisa X, enabling interchangeable powder fills.

Chamber: Actively heated and filtered chamber; no nitrogen inert atmosphere; up to ~200°C.

Build Volume: 130×180×330 mm; minimum layer 75 µm; maximum 175 µm.

Software: Sinterit Studio (supports STL, 3MF, OBJ, 3DS, FBX, DAE).

Calibration

PA12 temperature profile: Maintain recommended temperature window for PA12 Industrial (~168–172°C surface); allow 30–40 min warm-up.

Laser power: Do not modify factory profiles for the 30W IR laser without a test print; uniform sintering is the criterion.

Recoater: Sieve recycled powder with 80–100 µm mesh; visual check of first 5 layers before leaving unattended.

Refresh rate: ≤50% recycled powder for PA12 Industrial; monitor cake colour as a visual indicator.

Common defects

Warping: Higher speed of SUZY → more dynamic thermal field → corner parts more vulnerable. Tilt ≥45° and use slow cooling cycle.

Orange-peel: Caked or un-sieved recycled powder → streaks. Maintain high proportion of virgin powder.

Powder degradation: Without nitrogen, polymer chains oxidise → yellower parts and lower strength beyond 50% recycling.

Porosity on thin walls: Use thin-wall profiles in Sinterit Studio; minimum wall ≥1.0 mm.

What it is used for

Small-batch PA12 production: 35% faster throughput at the same build volume as Lisa X: economically justified for batches of 20–100 parts.

Office-safe prototyping: Active filtration and compact design without special ventilation.

Long-term academic use: Laser with >30,000 h life → low maintenance cost for academic environments.
