David vs.Goliath using a 3D Printed Catapult!

This catapult was ‘printed’ on a Stratasys Objet Connex Multi-Material 3D printer. The material is Stratasys Objet Digital ABS Material – a special composite material able to functionally simulate real ABS 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 catapult is an excellent benchmark for demonstrating the capabilities of the Digital ABS Material to perform under tension and compression.
