SmartAgain® brings new opportunities to FDM/FFF technology

FDM/FFF technology although cheap and accessible, the printed objects often have a rough surface, are either too brittle or flexible, and are not durable because not resistant enough to heat, chemicals or hydrolysis. And they have a low degree of predictability for industrial scale production e.g. for injection molding.

SmartAgain® is a high performance engineering material which combines the properties of polyamides (PA, or nylon) and polyolefins such as polypropylene (PP). Its special material features make the impossible in the past become possible now.

Elegant, soft-touch and print fast

SmartAgain® responds accurately to the movement of print nozzle. Its surface morphology is comparable to natural silk.

The printed objects are precise and detailed with an elegant matt and soft-touch surface.  It can print very fast with the standard 0.4mm nozzle. Because the 0.3mm layer height printed objects have almost no visual and dimensional difference compared with objects printed at lower layer heights.


Strong and durable

In conventional engineering plastic applications, over 80% of the materials are polyolefins such as PP and HDPE, and polyamides (nylon) such as PA6, PA66 or PA12.

They have one feature in common: Strong but not brittle. The mechanical properties of SmartAgain® is comparable to those of PA12 which is commonly used by SLS and MJF 3D printing.

In terms of durability, SmartAgain® is excellent in chemical and hydrolysis resistance thanks to the polyolefin part in the alloy. Regarding heat resistance, its HDT/B (0.46MPa load) is above 100°C, which is comparable to the FDM and SLS nylon materials,  but (much) higher than other common FDM materials such PLA, PETG, ASA etc.


Rivals injection molded objects

This is in terms of appearance, precision as mentioned before, but also of properties.

The FFF/FDM printed 100% filled SmartAgain® object can be a good prediction for the performance of its injection molded counterpart. SmartAgain® polymer is also available in granular form for conventional plastic processing technologies.


Printing design-free structure with single extruder

SmartAgain® can work as the support material for itself. After printing, the support structure can be broken away without or with very little footprint left on the surface of printed parts.

This feature allows it to print design-free structure with a single extruder. It saves significantly the print time compared with a two material dual extrusion system. The printed object is also stronger because there is no compatibility issue between the structure material and the support material.

SmartAgain® is the invention of QuinLyte which has the aspiration to establish a sustainable business via circular use of plastics.

Next to being produced from virgin materials, SmartAgain® can also be produced by recycling from SmartIn® high barrier film – the other invention of QuinLyte; or by recycling plastic parts made from SmartAgain® itself. In the near future, there will be a recycled version of SmartAgain® available for FDM 3D printing.


Printer requirement

  • Heated build plate > 85°C
  • Well leveled build plate (smooth surface preferred)

Although a closed print chamber is preferred, SmartAgain® can be printed under open environment. Its print profile is developed at Ultimaker s5 and has been verified at various brands of 1.75mm printers from such as JG Maker, Prusa and Creality.

SmartAgain® enables hassle-free printing. It is not necessary to pre-dry the material, and to apply adhesives or glues on the build-plate. After printing, it is easy to remove the object and no need to clean the build-plate.
