3000 years ago David defeated Goliath with a leather slingshot and a well-aimed stone to the forehead. Seeing their champion defeated, the opposing Philistine army fled, leaving David to claim the field – and the hand of the King’s daughter in marriage. That’s not a bad return for his investment.
Today we’re taking that historic battle to new proportions. Watch as our 3D printed ‘David’ (please excuse the fact that he’s not dressed, all complaints to Michelangelo) defeats Goliath with a 3D printed Siege Catapult. Providing our David with moral support is our Halo 2 battle figure. You can watch how we created him in this video here.
This Catapult was ‘grown’ on an Objet Connex Multi-Material 3D Printer, using our ABS-like Digital Material - a special composite material able to functionally simulate ABS-grade engineering plastic. All parts of the Catapult were printed together at the same time on the same build tray – including the extendable arm, the spring and the tension screw. The Siege Catapult excellently demonstrates the capabilities of the ABS-like Digital Material to perform under tension.
