Aura3D A8 – Large Format Industrial Pellet 3D Printer

The Aura3D A8 is a pellet 3D printer designed for large-scale production, with a build volume of 800 × 800 × 800 mm. By using plastic pellets instead of traditional filament, the printer offers a cost-effective solution for producing large-scale prototypes, masks, fixtures, molds, and functional components. Support for a wide range of polymers and composite materials makes the A8 suitable for various industrial applications.

Highlights

• Large print volume: 800 × 800 × 800 mm for printing large components
• Pellet extrusion (FGF): uses 1–5 mm plastic pellets instead of filament.
• Flexible nozzle options: diameters from 0.4 to 8.0 mm
• High printing temperatures: 2 heating zones reaching up to 380 °C (upper) and 450 °C (lower)
• Automatic material feeding: hopper with a 15 kg capacity
• Various print surface options: aluminum, tempered glass, or PEI.

Large build volume and stable structure

With a build volume of 800 × 800 × 800 mm, the Aura3D A8 is capable of printing large components in a single piece, reducing the need to split models into smaller parts. The machine measures 1250 × 1240 × 1645 mm and features a stable frame structure designed to ensure excellent stability during printing.

The Core-XY system and linear guides control the printer's movements and contribute to a smooth and controlled printing process. The structure is designed for the large-scale printing of prototypes and functional components.

Pellet extrusion with multiple temperature zones

The Aura3D A8 uses plastic granules measuring between 1 and 5 mm as raw material. Granule printing can reduce material costs compared to filament printing, especially in the production of large objects with high material consumption.

The extrusion system is equipped with two heating zones to optimize material melting. The upper heating zone reaches 380 °C, while the lower nozzle heating zone reaches 450 °C. This allows printing with a wide range of thermoplastics and high-temperature composite materials, depending on the specific requirements of each material.

Automatic material feeding

The integrated material hopper can hold up to 15 kg of granules. An automatic feeding system transports the material from the hopper to the extruder, reducing the need for manual refills during printing.

The system is designed to handle large-scale prints and extended production cycles.

Materials for various industrial applications

The Aura3D A8 is designed to work with various types of thermoplastics, including engineering polymers, fiber-reinforced materials, and recycled plastic raw materials. The choice of material must be adapted to the printing parameters and machine configuration.

Examples of materials specified for the printer include:

• Engineering polymers and composites: PAHT-CF, PC-GF/CF, PETG-CF, PPS-CF, ABS-CF, and ASA-GF
• Standard materials and flexible polymers: PP, TPU, PLA, and ABS
• Recycled materials: rPETG, rPLA, and rPET

Flexible options for nozzles and build surfaces

Thanks to nozzle diameters ranging from 0.4 to 8.0 mm, the Aura3D A8 adapts to various printing needs. Smaller nozzles are suitable for achieving greater detail, while larger ones allow for higher material flow rates and can speed up the production of large components.

The print surface can be configured with aluminum, tempered glass, or PEI, depending on the preferred configuration and material requirements.

Applications

The Aura3D A8 is suitable for various types of large-scale production and prototyping, including:

• Large-scale prototypes and functional industrial components
• Masks, fixtures, and production tools
• Molds for various industrial processes
• Footwear, furniture design, crafts, and architectural models.
• Components for technical research and educational applications
