The Objet 500 Connex3, is a UV-curable resin based 3D printer. Inkjet print heads are used to jet liquid photopolymers onto a build platform. The material is immediately cured by UV lamps and solidified, which enables multi-layer deposition. The printer is capable of patterning multiple polymer materials simultaneously.
The system supports a very wide range of thermoplastics, photopolymers, elastomers, and functional polymers that can be combined concurrently in a single fabrication run to create “digital materials,” and integrate these materials into complex 3D structures with particular relevance to robotics and microsystems applications. Because the different classes of polymer can be deposited and patterned in a single workflow, exceptionally complicated and multifunctional elements can be realized which otherwise would be impossible to achieve using traditional manufacturing methods. For instance, a rigid structure could contain complex geometrical features which can include a rubber like polymer.
The tool offers a large build volume of 50 x 40 x 20 cm, with a maximum resolution of 16 µm. Every print requires support material on the bottom and for overhangs. The support material can be easily dissolved, or can be quickly removed with a water jet.
I've been working with this system since 2015. It is indeed the printer that yields the best quality prototypes, and has the widest variety of applications. In the video below one can appreciate the writing process. Take into consideration that some of the material being deposited is support material. Every print needs support material in the bottom, and for overhangs. The support material dissolves easily, or can be quickly removed with a water-jet.
