pump is said to ensure very tight control of filament diameter in standard specification. “3Dprint is still something that needs to prove its


self,” says Dirk Leister, Leader Technical Marketing in the company’s Material Characterisation Prod- ucts unit. “But we have customers in universities and in business that want to work with materials that are not commercially available.” Italy’s Maris says a priority in the development

User acceptance Noris Plastic premiered its latest laboratory compounder, the ZSC 20 (also with 20mm screws). “This machine type is characterised by high user acceptance, especially in the development of masterbatches and special compounds,” says the company. “Used in industry and universities, compounders of this series are used in research and development as well as in small-scale production.” A special feature claimed for

this extruder system is its ability to process a wide variety of materials. “Added to this is the very fast changeover capability which helps to gain quick insights in test and development tasks,” Noris says. Different materials depending on forecast wear requirements are available for the processing unit. In addition, a wide range of downstream units and accessories is available. ThermoFisher showed a laboratory scale compounding line configured for production of 3Dprinting filaments. Built around its Process11 lab-scale twin screw compounder, the line included a gear pump, die, water bath and winder. With an output rate of between 20g and 2kg per


hour, the 11mm diameter extruder is fully ported and can handle powder and liquid materials as well as standard pellets. An optional inline meas- urement system is also available, although the melt

of its TM20 Hi-Tech twin-screw lab extruder was the ability to accurately and reliably predict scale-up. “The scale up from this type of equipment is not immediate but can be calculated by considering the following: different factors of heat exchange (as a function of the barrels diameter); feeding configuration for powders and liquids,” the company says. It offers a calcula- tion programme for scale-up escalation. The TM20 is equipped with


20mm screws and offers an ID:OD


ratio of 1.55 and maximum torque of 47 Nm. The machine features a modular configuration with key elements such as the control system all integrated into the frame to save space. It is said to be suitable for a broad range of applications, including polymer alloying, reactive extrusion and devolatilising as well as produc-


tion of commodity and engineering plastics compounds and masterbatches.


High torque options Moving up in size, Polimer Technics has intro- duced high torque options for its Poex T Series twin screw extruders – which includes the T27, T40, T60, T75, T94 models – to allow better scale-up to production lines. The company says the Poex T27 (which has 27mm diameter screws with an ID:OD ratio of 1.55 up to 1.76, depending on application) has been designed especially as a laboratory compounder for R&D work as well as for optimis- ing new product formulations. It is said to feature easy operation and high flexibility in operation, thanks to its modular construction that allows screws and shafts to be changed very quickly.


“Due to the fact that it


requires only a small area and can easily be moved, the user gets the flexibility of a lab
