Roboze is to launch its new Hypermelt technology for the ARGO 1000 3D printing system at Formnext.

Hypermelt technology has been described as ‘revolutionary’ by Roboze, who suggests the ARGO 1000, when equipped with Hypermelt, is the largest pellet-based 3D printer in the world.

The ARGO 1000 machine was debuted at Formnext 2021, and has since been the focus of several collaborations with key market players who have fed back that the production of components larger than 500mm with Fused Filament Fabrication technology is challenging.

Hypermelt has therefore been developed to address this issue.

With Hypermelt and its ARGO 1000 system, Roboze claims it can produce parts with a production speed ten times higher and costs reduced by up to 60% compared to other filament methods, while also maintaining a high deposition accuracy compared to large format pellet 3D printing systems currently on the market. A heated chamber of up to 180°C, a printing volume of 1000 x 1000 x 1000, and an Independent Dual Extruder capability makes Roboze confident it can produce large-format parts in high quality, whether they be made from unfilled super polymer or strong composites. Roboze’s ARGO 1000 is able to produce parts in super polymers like PEKK and ULTEM 9085, as well as carbon fibre-filled PEEK, PA, elastomers, recycled materials and bio-based polymers.

Additionally, an extrusion rate of up to 2kg/h is said to reduce production times and allow ‘quick access to the necessary parts.’

«Hypermelt technology offers our customers the possibility to produce large production batches competitively compared to traditional techniques and to obtain components up to 1 cubic meter at a cost far lower than current large-format filament technology, with up to 10 times the speed,” commented Roboze CEO Alessio Lorusso. “This innovation marks a new era in 3D manufacturing with advanced materials.”

Simone Cuscito, Chief Research and Development Officer at Roboze, added: «Hypermelt technology represents an extraordinary evolution in additive manufacturing, with the potential to completely change the way the world produces large format parts in high-performance materials. We are proud of this important result achieved thanks to the commitment and vision of the Roboze team and to be at the forefront of this transformation. We believe that the combination of Hypermelt technology and ARGO 1000 is a turning point in the history of the manufacturing industry.»

Roboze additive manufacturing (AM) technology is built on four differentiating factors to improve overall parts performance compared to the competition

• Beltless pinion-rack system for controlling the movement of the machine in all directions, permits a precision of down to 10 μm.
• High Viscosity Polymer (HVP) Extruder.
• Heated chamber, securing uniform heat distribution to parts during printing.
• A wide selection of engineered materials to meet the most demanding applications

Beltless System
Direct movement is secured with a helical rack and pinion. This ensures that accuracy can be as fine as 10μm / 0,4 mil with a repeatable precision of 5μm.
This ensures that both fine and repeatable parts can be produced with all of Roboze machine range. The beltless system also provides another benefit in requiring less maintenance.

HVP Extrusion system
The HVP extruder is specially developed to work with high viscosity materials by providing the least amount of friction inside the nozzle as well as temperatures of up to 450°C at the nozzle to minimize any shrinkage phenomena and ensure a proper preservation of chemical-physical properties of the extruded material.
Optimized polymer flow & temperature ensures that parts are produced with good quality.

Heated air enters the chamber from both sides and air is circulated via the bottom of the chamber and re-heated to be fed back into the loop.

The Roboze heated chamber is the result of years of work, prototypes and hundreds of simulations. We developed this unique solution to allow a homogeneous working environment aimed at consolidating the parts with a perfect thermal fusion of each layer in order to achieve exceptional mechanical properties. This is among the most important elements of the Roboze Automate technological ecosystem as it has a strong impact on the mechanical properties of the final component.

Heated chamber
The heated chamber features uniform heat around the part and sensors to precisely control temperature, critical to production of parts using polymers. The chamber is capable of a continuous temperature of up to 180°C, with local variations of temperature kept within a 5-10°C.

Produce your parts in a few hours, with Roboze machines on your shop floor. Roboze additive manufacturing (AM) technology is built on four differentiating factors to improve overall parts performance compared to the competition.

Roboze machines can produce parts in a wide range of materials, from higher end materials such as PEEK/PEKK all the way down to the less complex PP/ABS/PLA polymers. Materials can be produced with reinforcements in the form of either carbon fibres or ceramics, to improve materials properties.

The table below gives an overview of some key material properties of Roboze materials and their suitability dependent on what kind of material properties are most important to you.

Key material properties are listed on a scale of suitability from 1 to 5, where 1 is least suited and 5 is most suited. All materials technical datasheets are available on request.
