Stratasys Origin Two

The Stratasys Origin Two is a DLP 3D printer from Stratasys with a 192 x 108 x 350 mm build volume.

Specifications

Light Engine (P3 DLP: 5K)

Origin Two uses P3 (Programmable PhotoPolymerization) with a new 5K DLP projector (5120×2880 pixels) at 385 nm UV. Pixel size: 38.5 µm: a significant improvement over Origin One (~50 µm). Light dose is controlled pixel-by-pixel for maximum uniformity.

Optics

DLP matrix with per-pixel brightness calibration; the entire XY field is exposed simultaneously (no galvanometer scanner). Working wavelength: 385 nm (not 405 nm: important for resin selection).

Platform

Precision Z-motor with FEP-release vat and peel-force monitoring. Documented accuracy ±50 µm with >93% repeatability across printer farm units.

Chamber.

Calibration

5K DLP Projector Verification

Built-in diagnostics check UV uniformity (threshold >96%). Deviation requires light module replacement.

Chamber Heating (up to 60 °C)

Allow full stabilisation ~15 min before starting. Tolerance < ±0.5 °C throughout the print.

Build Platform Levelling

Z-zero procedure with Origin Two tool; tolerance ±0.020 mm. Mandatory after every vat change.

Farm Repeatability Validation

On farm installations: identical artefact on each machine, CMM comparison.

Common defects

Suction Cupping

On solid planar cross-sections without drainage holes. Fix: add minimum 1.5 mm drainage holes, anti-suction supports, reduced lift speed.

Unprintable Thin Walls (<0.35 mm)

At low UV dose or with a fouled FEP. Fix: +10% UV dose, inspect/replace FEP.

Warping at Flat Base

Internal stresses from 60 °C chamber temperature with rapid cooling. Fix: gradual thermal transition, stiffening ribs, optimised supports.

Insufficient Hardness on HDT >150 °C Resins.

What it is used for

Aerospace Brackets and Connectors (AS9100)

±50 µm accuracy + >93% farm repeatability = direct AS9100 verification; HDT up to 300 °C covers avionics requirements.

Medical Devices (ISO 13485)

P3 closed-loop control + documented repeatability = production process control for regulated environments.

Precision Connectors for Consumer Electronics.
