Top 10 Large scale Industrial 3D printers

When it comes to 3D printing, bigger doesn’t necessarily mean better. That said, large-scale 3D printing systems do offer unique manufacturing solutions that smaller systems cannot achieve. They can, for example, produce large prototypes and parts and even multiple series of smaller parts simultaneously. The advantages of large-scale 3D printing being clear, this one area that has seen a lot of activity in recent years. In light of this, we’ve put together a list of some of the top large-scale 3D printers on the market for industrial applications. We’ve generally tried to include AM systems with build volumes over 500x 500 mm.

1. voxeljet’s VX4000

Technology: Binder Jetting
Build volume: 4,000 x 2,000 x 1,000 mm
With a build volume of 4,000 x 2,000 x 1,000 mm, voxeljet describes its VX4000 as ‘the world’s biggest industrial 3D printing system for individual sand moulds and cores’. Additionally, the system can also produce small-series components and has a resolution of up to 300 dpi.  
The VX4000 uses Binder Jetting technology, which works by depositing droplets of a binder agent to fuse the powder material together. In contrast to many other systems, the build platform of the VX4000 is not lowered following each completed layer; instead, the print head and coater are raised. This allows the machine to bear the substantial weight of its build platform. The system also promises virtually continuous production thanks to its interchangeable build. Suitable for metal casting, the technology is a boon for industries like foundry or companies using casting and moulds in any way.
One thing to keep in mind, however, is that the VX4000 comes with a hefty price tag: just over $1.5 million. But if such an investment proves too steep, voxeljet’s 3D printing services give you the chance to take advantage of its technology.    



2. ExOne’s Exerial

The ProX 950 ranks as one of the largest industrial-grade SLA systems on the market. SLA typically works by using a laser to cure and solidify a vat of photopolymer resin, allowing parts to be built one layer at a time. With the ProX 950, two lasers are used.
The ProX 950 can produce high-quality parts up to 1.5 m in one go — removing the need for assembly. It produces parts with a high level of surface quality and accuracy, with its accuracy said to rival that of CNC machining. In addition to its large printing capacity, the ProX 950 can also be used for low-volume series of smaller parts. It suitable for use with a wide range of photocurable plastics and composites and features a material delivery module for fast material changes.
Applications of the technology include casting patterns, jigs and fixtures, medical models and functional prototypes.


5. The EOS P 810

EOS P_810 Industrial 3D printer
Technology: Selective Laser Sintering (SLS)
Build volume: 700 x 380 x 380 mm
This year’s Rapid + TCT trade show saw EOS launch its P 810 for the first time. The launch expands the company’s already extensive portfolio of SLS 3D printing systems. Developed in cooperation with Boeing, the P 810 system is designed for use with HT-23 – a high-performance, high-temperature plastic. It is the first carbon fibre-reinforced PEKK material to be used with EOS’s systems, and produces high-strength, lightweight parts.
That the P 810 is designed to be used specifically for the high-performance material makes it particularly suited to the aerospace industry, where strict requirements like UV resistance and flame retardancy must be adhered to. However, the system is also suitable for highly demanding applications in other industries, like automotive, or for producing large and highly accurate structural components like spare parts for the interior and exterior of buses and trains.

6. BeAM’s Magic 800

BeAM Magic 800 Industrial metal 3D printing system
Technology: Direct Energy Deposition (DED)
Build volume: 1200 × 800 × 800 mm
One of BeAM’s flagship AM systems, the Magic 800 uses DED technology to produce metal parts. The system works by using a powerful laser to fuse powdered metal material by melting it as it is deposited. According to the company, its industrial AM systems typically use a deposition nozzle mounted on the Z-axis of a CNC machine, giving them a 5-axis motion.
The Magic 800 is particularly well-suited for repairing various parts and components like aircraft turbine blades. In addition to repairing or adding features to existing parts, the Magic 800 can be used to produce small metal parts, and complex parts can be manufactured in a range of metal alloys. Its 5-axis movement is said to remove the need for support structures, reducing post-processing requirements.
