Description

The design of the Composer A4 is based on the proprietary technology of CFC — co-extrusion of continuous filament composites reinforced with thermoplastic polymer, developed by Anisoprint engineers.

Printers of this brand allow users to create models, equal in durability and hardness to the objects produced using selective laser sintering technology. The manufacturer named the proprietary technology ‘anizoprinting’.

The essence of the technology is simple. The device has two extruders: the first one — for FDM printing with plastic filament, the second one — for printing with CCF or other reinforcement fiber, which preserves the structure of the continuous filament, instead of lying within the filament in the form of chopped strands, as it is in other “composite” 3D printing technologies.

Continuous Carbon Fiber (CCF) is Anisoprint’s proprietary product. Its strength characteristics are double that of aluminum, while the weight is twice as little.

Due to the continuity of fibers, proper saturation, and high volume ratio of carbon fiber in a ready-made object, reaching up to 30 per cent, models printed on a Composer A4 are considerably superior to similar models from refractory plastics, such as PEEK or Ultem, in terms of durability.

Anisoprint Composer A4 is a dual extruder 3D printer with an enclosed chamber and a rigid machined aluminum frame. One of its extruders prints with plastic filament, the other — with composite material. The printhead module was designed by the company’s engineers.

The 3D printer uses the CoreXY kinematics and features a heated bed with a removable glass print surface.

The leveling is performed semi-automatically — with the help of screws below the print bed.

Filament and carbon fiber spools are located outside the printer, on its back wall. The filament is fed through Bowden tubes.

 

Software

This unique technology requires a whole new approach to the preparation of digital models for printing. The company’s proprietary software Aura allows users to accurately adjust the printing of the object's internal and external surfaces and select the operating parameters for carbon fiber and pure plastic.

Aura is compatible with all FDM printers; it is provided totally free of charge. Anyone can download the proprietary software from the company’s official website.

 

Characteristics of Printed Items

The technology of continuous filament composites co-extrusion, known as anizoprinting, allows users to work with all type of filament, provided that its melting point does not exceed 250 °С — PLA, ABS, PETG, nylon, polycarbonate, and thermopolyurethane. Composites with chopped particulate fillers are also compatible.

We tested two samples printed on a Composer A4. One of them was made from pure PETG with 100% infill ratio; the other — from the same plastic filament, but with three perimeters of composite carbon fiber CCF. The test results were as follows: the first sample was broken under the load of over 9 kg, the second — over 35 kg.

Carbon fiber CCF is manufactured by Anisoprint and supplied in 750 m spools. One spool comes fitted with the 3D printer.

With the help of Anisoprint Composer A4, you can produce 3D models of almost any shape, with a complex inner structure. Excellent stress-strain properties of printed objects make this technology highly demanded in different engineering industries, from aerospace to automobile and robot production, — in all industries, where durability, toughness, and lightness are required.

This sums up our review of the professional Anisoprint Composer A4 3D printer.
