The Clear Aligner Production Line. Scan in. Aligners out.
A turnkey, automated manufacturing system for clear aligners — model printing, thermoforming, laser marking, and robotic trimming engineered to run as one line.
Most vendors sell you a machine. We build the production system behind it.
Eight steps. One system.
Every stage is specified, timed, and connected — so throughput doesn't depend on your most experienced technician.
Scanning & data acquisition.
Every case starts with your scan. The workflow is open by design — it accepts data from all major intraoral scanners, with direct STL / PLY import, so incoming cases flow straight into production without conversion detours.
Treatment planning.
Keep the planning software you already trust — the line integrates downstream of any staging workflow. Need design capacity? RayForm connects you with professional design centers that generate 20–50 step movement plans from the doctor's prescription.
Nesting & slicing.
One click lays out models from dozens of patients across the build platform, each with a unique ID to prevent mix-ups downstream. On the production printer's 768 × 432 mm platform, that means 96–120 arch models nested into a single batch — nesting density is throughput.
High-volume 3D printing.
The production printing cell turns a full plate of arch models around in about 45 minutes and runs 7×24 unmanned — automatic part removal, sorting, and resin refill included. Models print in RayForm Ortho Model Resin, engineered for thermoforming with high heat resistance and surface hardness, so molds hold their geometry under the forming heat.
Automated washing.
Residual resin comes off with a two-stage coarse-plus-fine cleaning SOP for a tack-free surface — the precondition for aligner clarity. Run it as ultrasonic + IPA, or go solvent-free with the RFADM-03 centrifugal spinner for a cleaner shop floor.
UV post-curing.
A 405 nm UV post-cure brings every model to its full mechanical specification before it meets the forming station — so molds don't creep, collapse, or deform when the heated sheet presses down.
Automatic thermoforming.
The automatic forming station heats and vacuum-presses aligner sheet onto the printed molds — two aligners per cycle in 30 seconds or less, held to ±0.3 °C temperature control, with a rework rate under 1%. Repeatable forming is exactly where manual pressure-forming shops lose money.
Marking, trimming & QC.
Machine vision reads each unit's ID at a ≥98% recognition rate, the green laser marks case number, logo, or QR code at 0.01 mm line width, and an ABB six-axis robot trims along the gum line in 25 seconds or less at under 0.3 mm deviation. Every aligner leaves the line traceable, trimmed, and QC-checked.
Built for throughput.
These aren't lab-bench numbers — they're the working specifications the line is built and accepted against.

Four cells, one system.
Each station is a specified machine cell — installed, connected, and accepted as one line.
Production printing.
Large-format DLP cell that keeps models flowing into the line around the clock, with automatic part handling and resin refill.

Automatic thermoforming.
Heats, positions, and vacuum-presses aligner sheet with process control tight enough to make forming a non-event.

Robotic trimming.
An ABB six-axis robot guided by Hikvision machine vision cuts each aligner along its gum line — consistent edges, no fatigue.

- Trim accuracy<0.3 mm
Need a smaller footprint? The all-in-one aligner machine combines forming, marking, and trimming in a single cabinet — one aligner every 45 seconds. Line equipment integrates with factory systems via TCP/IP and RS-232/485.
The materials that run it.
The line is only as consistent as what you feed it — model resin, aligner sheets, and a direct-print route when you want to skip the mold entirely.
Ortho Model Resin.
Purpose-built for thermoforming working models — high heat resistance and surface hardness, so geometry survives the press.
