WEB EXCLUSIVE: Objet Inc., Billerica, Mass., has come out with a material (RGD525) for simulating the heat resistance of engineering thermoplastics, together with outstanding dimensional stability for static 3D models and prototypes. It is currently available for the company’s Connex500 and Eden500V 3D printers. Objet materials are proprietary liquid acrylic-based photopolymers that cure under UV light. RDG525 has an HDT of 65 C/149 F (@66 psi) right out of the printer and 80 C/176 F after a short oven post-cure. It also has a tensile strength of 10-11.5 kpsi, flex modulus of 450-510 kpsi, and notched Izod impact of 0.26-0.3 ft-lb/in.
This material follows last year’s launch of a clear, biocompatible material (MED610), an ABS-like grade (RDG5160-DM), and rigid clear and white materials (VeroClear and VeroWhitePlus).
