OverviewThe BigRep ALTRA 280 is a large-scale industrial 3D printer engineered for high-temperature printing, automation and full material flexibility for demanding industrial applications. It produces production-ready components using engineering and high-performance polymers.
Key Features- Heated Build Chamber: 280‑liter build chamber heated up to 180°C for stable, accurate large-format prints.
- 4 DSX Extruders: Up to four synchronized Direct Synchronized Extruders (DSX) for complex multi-material parts and continuous production (water-cooled, integrated sensors, Relay Mode for filament backup).
- High-Temperature Material Compatibility: Extruders capable of up to 450°C enabling ULTEM® 9085, PEKK, PEI and other high-performance polymers.
- Heated Vacuum Print Bed: Vacuum print bed heated up to 180°C with material-specific surfaces for strong first-layer adhesion and controlled part release.
- Open Material System: Print with BigRep or compatible 3rd-party filaments including PEEK, ULTEM®, PEKK, PA12-CF, PC and others.
- Automated Quick Start & Calibration: Automated topology measurement, adaptive mesh bed leveling and automated calibration for rapid, repeatable setup.
- Industrial Frame & Motion: Welded frame, ball screws and servo motors deliver positional accuracy and stability over long print durations.
- Integrated Monitoring & Filament Management: HD wide-angle camera, out-of-filament detection, pause/resume and Relay Mode for uninterrupted production.
Applications & Example Use-CasesManufacture durable end-use parts, jigs and fixtures, functional prototypes and aerospace or automotive tooling at full scale. Example applications include aerospace fixtures (PEI/ULTEM), automotive functional prototypes (PC), gear racks (PEKK-A) and custom aerodynamic components.
