Heated vacuum print bed

HEATED VACUUM PRINT BED

Secure Print Adhesion

Improve your print success thanks to the vacuum print bed with material-specific print bed surfaces. Your prints stay put while still easy to remove after printing. Heated up to 180°C with embedded electrical wiring, the vacuum print bed's achieves extremely homogeneous temperature distribution. This ensures accurate prints and superior layer adhesion even while producing large intricate parts.

Even temperature distribution

EVEN TEMPERATURE DISTRIBUTION

For Top Mechanical Performance

Consistent temperature is key for excellent prints and a requirement for high-performance parts. Reaching temperatures up to 180°C, the ALTRA 280 print bed maintains uniform heat distribution. The Airflow control technology tempers the prints precisely translating to parts with consistent mechanical properties where other 3D printers face delamination and inconsistencies.

Even temperature distribution

OPEN MATERIAL SYSTEM PRINTS ALL COMPATIBLE FILAMENTS

The heart of all BigRep machines is the material system that’s open for innovation. Print with any compatible filament of your choice – BigRep’s or a 3rd party’s – and unlock new applications with the ALTRA 280.

BigRep's portfolio of industrial-grade 3D printer filaments ranges from affordable, general-use materials to technical materials for demanding industrial applications. They are created under carefully controlled conditions to guarantee uniform diameter and consistent composition ensuring reliable, even extrusion.
