Description
Accuracy in Large Scale
The Generous Build Chamber
With a build chamber of 500 mm x 700 mm x 800mm (build volume of 280 liters) it can produce intricate full-fledged prototypes, production, and end-use parts. Thanks to the welded frame, ball screws and servo motors like those found in CNC technology, ALTRA 280 achieves the accuracy and repeatability you expect in an industrial machine. Experience unrestricted print freedom, and reliably print precise parts without compromising on size.
High-Temperature Capabilities
High-Performance Parts
The build chamber and print bed reach up to 180°C, enabling applications using high-performance materials such as ULTEM 9085 and PEEK. During printing the build chamber doubles as a tempering system, enhancing the mechanical properties, functionality, and dimensional stability of the parts.
Up to Four Reliable DSX Extruders
Uninterrupted Productivity
The ALTRA 280 is equipped with up to 4 DSX (Direct Synchronized Extruders) capable of printing at 450°C up to 20kg in one cycle. Achieve complex prints with dual extruders and ensure seamless production with two respective backup extruders. Each DSX is a masterpiece, with integrated cooling channels and multiple sensors for monitoring and control.
FULLY AUTOMATED QUICK START
Print at the Push of a Button
Getting started is quick and easy with ALTRA 280 thanks to the numerous automatic functions including print bed calibration via topology measurement and corresponding automatic compensation. After a smooth start, many built-in sensors will secure your 24/7 operation while the HD wide angle camera enables real-time remote monitoring so you won't miss a thing.
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
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.
