David vs.Goliath using a 3D Printed Catapult!

As seen on the Objet blog. (www.objetblog.com) This catapult was 'printed' on an Objet Connex Multi-Material 3D Printer. The material is Objet ABS-like Digital 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 ABS-like Digital Material to perform under tension and compression.

@StormRisingOriginal - congrats on getting the Objet VeroBlue! It's a great material that many of our customers use for highlighting the fine nuances of a detailed 3D print model - especially if the model is to be used for photography purposes. the ABS-like Digital Material is a great functional material - use it to create moving parts that work under stress. All the best!

@ stop4stuff; difficult to tell, it all depends on how much you tighten the screw. So far we've managed about 20 shots..

muhahahaha, it's tickles.

Goliath didn't look too suprised by the attack. ^^

I just bought a bunch of Vero Blue parts from Kraftwurx com. Wow Vero Blue is awesome! ABS-like is next!

You guys just have way too much fun :)

Seriously though the model is pretty impressive.

What would you expect the lifetime of the spring to be?

Ehm... you need better amunition...

By the way, are you interested in produce a 3d printer for hobby-shops that could print miniatures on demand for the main brands and others that came with the 3d model files ( or other system safe for the company producers ) ? It would be great to see that as the way to produce and sell miniatures because shipping cost and money exchange ( plus others restrictions ) make the hobby even more expensive that it actually is.
