A garden of rapid prototyping

Objet has launched its new Eden330 Rapid Prototyping system that features its second generation polymer-jetting technology called PolyJet.

At the heart of the RP system, the PolyJet system allows the user to build models with super fine layers down to 16 microns (0.0006 inches) and thin walls down to 0.6 mm (0.024 inches), eliminating a common problem in RP systems, that of the ‘stair’ or ‘step’ effect.

Each layer of the deposited Objet-developed photopolymer is cured (hardened) by exposure to UV light.

Building of the prototype takes place with two different materials: one is used for the actual model, while a second, gel-like photopolymer is used for support, and is easily wiped off or removed by water jets.

The company claims that the new system offers the biggest build size for a standard Rapid Prototyping system – a full 340mm x 330mm x 200mm (13.4 inches x 13 inches x 7.9 inches).

Eden330 is also an ‘office-friendly’ product, with environmentally stable, fully cured materials. There is no contact with the resins, which are supplied in 2 kg, fully sealed cartridges. A built-in materials management system called PolyLog shows the user when he should exchange the cartridge.
