VX200 HSS

The VX200 HSS is an MJF 3D printer from voxeljet with a 290 x 140 x 180 mm build volume.

Specifications

VX200 HSS: Technical Specifications

Process / Print Head

The VX200 HSS uses HSS (High Speed Sintering): a member of the jetted-agent + IR-fusion technology family alongside HP MJF and Stratasys SAF. A piezo inkjet head with ~3,000 individually addressable nozzles at 360 dpi jets an IR-absorbing fluid (Absorption Agent) onto a polymer powder layer. A broadband IR lamp then passes over the entire bed, fusing the marked zones in a single pass: no laser, no scanning beam required.

IR Lamp

A single IR lamp irradiates the full-width layer in one pass. Lamp uniformity is critical: a ±10 °C non-uniformity can produce orange-peel surface texture or incomplete fusion.

Calibration

VX200 HSS: Calibration

Powder Bed Leveling

Check platform and recoater horizontality before each build campaign. Deviations > ±5 µm across the bed width produce uneven layer thickness and directly affect mechanical properties.

Inkjet Head Cleaning

Run automatic cleaning of ~3,000 piezo nozzles before every cold start and after interruptions > 4 h. Inspect the nozzle test pattern: even 0.5 % blocked nozzles produce visible streaks in parts.

IR Lamp Uniformity.

Common defects

VX200 HSS: Common Defects

Orange-Peel Surface

Cause: non-uniform IR power or incorrect pre-heat temperature. Fix: thermal camera calibration + lamp replacement when deviation exceeds 10 °C.

Incomplete Fusion

Cause: clogged nozzles or insufficient IR power. Fix: head cleaning procedure + increase drop volume in ProPrint.

Warping

Cause: thermal gradient during cooling of flat/thin parts. Fix: orient parts at 15–30°, extend cooling phase, add powder buffer around ribs.

What it is used for

VX200 HSS: Use Cases

Material R&D Qualification

The open ProPrint SDK is unique in the HSS family: full parametric control for qualification of non-standard polymers (TPU, PEBA, EVA).

Functional Prototypes

PA12 and PP parts with injection-moulding-comparable mechanical properties; support-free production for complex geometries.
