New Arburg Freeformer has 2.5 times larger build chamber

Arburg introduced the new Freeformer 750-3X. Its build chamber is around 2.5 times larger than that of the Freeformer 300-3X. The significantly enlarged build chamber measuring 330 mm x 230 mm x 230 mm.

The new Arburg Freeformer 750-3X, whose large build chamber is particularly suitable for the rapid series production of large components or several articles per construction order. The principle of material preparation remains the same in the Freeformer 750-3X, but the entire system – preparation and discharge units – has been optimised so that the new unit could be designed more compactly. From a strictly external point of view, the Freeformer 750-3X cannot be distinguished from the 300-3X, as it has the same external dimensions. However, the part carrier is around 2.5 times larger at around 750 square centimetres – which is also what the name of the new system refers to.

 

Optimised melt pressure generators

The significantly enlarged build chamber, in which, incidentally, the temperatures are kept stable without any special air flow or circulation, is the result of several technical innovations. These include optimised melt pressure generators for dosing and injecting, which use servo motors from AMKmotion, a company in the Arburg family. This allows the three discharge units to be positioned more closely to each other and in a more compact way. Due to advanced software features of the control system, it was possible to increase the printing speed considerably. For example, process-optimised latticed support structures can be created where the build time is up to 55 per cent faster than with "conventionally" constructed ones.
