Medical 3D printer Form 3BL

SLAplastichigh-resolution

Overview
The Formlabs Form 3BL is a large-format medical 3D printer designed for production of life-sized anatomical models, large medical devices and high-volume clinical parts. It supports biocompatible and sterilizable resins and is intended for continuous operation with minimal operator intervention. The product page notes a successor model, the Form 4BL.

Key benefits

• Large build volume for 1:1 anatomical models and oversized medical components.
• Designed for high-throughput production with automated resin dispensing (two-cartridge capacity) to reduce mid-print interruptions.
• Cloud monitoring and fleet management via Dashboard for remote supervision and alerts.
• In-house replaceable components (LPU, rollers, optics window) to minimize downtime.

Performance & productivity
Build volume: 33.5 × 20 × 30 cm (21.4 L). Typical validated throughput: up to ~120 models per day depending on geometry, material and layout. Example workflow: using Draft Resin, ~24 orthodontic models printed flat in ~2.5 hours. Estimated example per-part cost: $2–3 (varies by geometry and workflow).

Materials & post-processing

• Compatible with a wide library of SLA resins including ISO 13485 manufactured biocompatible and sterilizable materials.
• Validated high-volume post-processing solutions: Form Wash L and Form Cure L.
• File preparation and printer management via PreForm and Dashboard.

Accuracy (validation)
Accuracy range: ±100 µm. Surface within accuracy range: 94% ± 8%.

Ecosystem & compliance
The Form 3BL is part of a production-focused ecosystem including nesting software, automated post-processing, validated workflows and production-scale accessories. Materials and workflows are validated for clinical use where noted; regulatory status depends on workflow and jurisdiction.
