Why BigRep's ALTRA 280 is the Next Big Thing in Industrial 3D Printing!

At the Rapid + TCT event, Daniel Barousse, CEO and Co-Founder of Slice Engineering had the opportunity to sit down with Max from BigRep to delve into the features and capabilities of their latest innovation, the BigRep ALTRA 280. This cutting-edge 3D printer brings a host of advancements to the world of industrial additive manufacturing.

Introduction to the ALTRA 280

The ALTRA 280 is designed to accommodate a build volume of 500 x 700 x 800 mm, providing ample space for large-scale printing projects. It features four independent extrusion units, allowing for the use of different materials simultaneously. This versatility enables users to print with various materials, including support and backup systems, and adjust nozzle sizes and layer heights as needed.

One of the standout features of the ALTRA 280 is its modular extrusion units. Should an extrusion unit encounter an issue, it can be easily removed, serviced, and reinserted without disrupting the overall printing process. This flexibility ensures minimal downtime and maintenance hassle.

BigRep’s Evolution and Partnership with Slice Engineering

Max shared insights into BigRep's journey from its beginnings in 2014 to its current status as a major player in the 3D printing industry. The company, originally focused on the German-speaking region, is now expanding internationally through its partnership with BigRep. This collaboration leverages BigRep’s extensive support network and expertise in large-scale 3D printing.

BigRep has made significant strides in developing printers capable of handling high-temperature and performance materials, catering primarily to automotive and aerospace applications. The ALTRA 280 continues this trend with its ability to handle a range of materials from ABS to high-temperature polymers like PEEK and Ultem.

Key Features of the ALTRA 280

1. Build Volume and Chamber Heating: The ALTRA 280’s generous build volume is complemented by a heated chamber capable of reaching temperatures up to 180°C. This feature, along with advanced thermal management and strong ventilation, ensures uniform heating and reduces warping, especially for large prints.

2. Modular Extrusion System: With four extrusion units, users can print with multiple materials and employ different nozzle sizes and layer heights. The system’s ability to handle various materials simultaneously—including soft and high-temperature materials—makes it highly versatile.

3. Filament Management: The ALTRA 280 supports various spool sizes, from small to large, and includes sensors to detect filament levels. It also features connections for a drying unit, crucial for maintaining the quality of hygroscopic materials.

4. Safety and Ease of Use: Safety is a top priority, with features like automatic shut-off when the door is opened and robust thermal management. The user interface is designed to be straightforward, allowing even those with minimal experience to operate the printer efficiently.

Applications and Use Cases

The ALTRA 280 is ideal for creating complex parts that require a combination of hard and soft materials. Examples include automotive components like air intakes, where flexibility and rigidity are essential. The printer’s ability to handle different materials and support configurations makes it suitable for producing functional prototypes and end-use parts.

Conclusion

The BigRep ALTRA 280 is a powerful addition to the industrial 3D printing landscape. Its large build volume, modular extrusion system, and advanced thermal management make it a versatile and reliable tool for a range of high-performance applications. As BigRep continues to innovate, the ALTRA 280 stands as a testament to their commitment to pushing the boundaries of what is possible in additive manufacturing.
