My Printrbot Simple finally works

Printrbot_Simple_01

I bought a Printrbot Simple back in July and was one of the first 80 people to get the final v2. It was a lot of fun to build the 3D printer from scratch. Just like LEGO back in the days.

The software setup was a bit problematic at first. The first prints were a mess due to wrong settings. But since Printrbot updated their “Getting Started Guide” it prints like a charm.

Usage and calibration is a bit more difficult compared to our Makerbot at Campus Münchberg. But in the end the principle of most extruders is the same.

Adventures in 3D Printing

Since October we have a Makerbot Replicator at Hof University. It took us a while to calibrate it and to learn how to model things in order to print. But better late than never we’ve got it running and it prints our things like a charm. Here are some photos and the latest prints.

Kinect Experiment: Freezing Han Solo

Princess Leia’s hologram message has already been recreated with Kinect. So Jens and i chose Han Solo frozen in carbonite.

This is an experiment with Kinect and Processing. People in front of it are posing like Han Solo and get frozen in 3D. We are already exporting the 3D models for 3D printing. So stay tuned. The software will be open source soon if anyone is interested.

Thanks to Sabine, Patrick, Manuel and Ianto for posing. Daniel Shiffman for the openkinect library. And NIN’s creative commons album “The Slip”.

Success!

rendering thom yorke on the “In Rainbows” LP in augmented reality

when radiohead released their “In Rainbows” album i bought the limited edition deluxe discbox. it’s good for markerless tracking! now thom yorke’s virtual head is rendered on it in augmented reality.

in our itacitus project at IGD alain and yulian developed a “poster tracker” for markerless tracking. it takes a photo of a flat object (poster, LP, iPhone screen) and extracts visual features. in instantreality it calculates the right camera position relative to the tracked object. thus it is very easy to write augmented reality applications without deep knowledge in computer vision.

ok. i trained the poster tracker for the “In Rainbows” cover and added the 3D data of “House of Cards” to it via peter’s script. now thom is singing on top of the album. thanks mario for the mac version!

update:

the tracking works on the iphone, too. ok. only when displaying the image on the iphone. but we are really porting instantreality to the iphone.
