3D Printed skull

3D Printing and Healthcare

Hospitals are now using 3D printing technology to turn medical scans into 3D models to plan surgeries and other treatment. 3D Systems is one such company - their web page contains a wealth of information about the technologies and techniques they employ. Another good example is Simbionix, whose site has examples of 3D printing heart models, and videos of the process.

Two good case studies are Mina Khan, who had her life saved by a 3D printed heart,and a young baby called Kaiba had his life saved by doctors using a 3D printed component to help him breathe properly.

4D animated scans of unborn babies have been around for a while now; companies such as 3D babies now offer the chance to turn these scans into 3D models.

Some researchers are also investigating how 3D printing can be used in prosthetics, particularly with a view to improving facial prostheses.

The Benefits of 3D Printing Healthcare is an article from Betanews which does a good job of explaining these technologies and how they might develop in the future.

This great 'Workshop manual' contains a lot of technical information about the Mars rovers (Sojourner, Spirit, Opportunity, and Curiosity) which is related to the ITGS HL Robotics topic. There is a wealth of information relating to the rovers' hardware, input and output devices, and communication equipment. Written with technical detail, these sections give students a chance to see real life robotic technology in action (did you know Curiosity has 2GB of flash memory?). A great addition to the ITGS classroom library.

Exercise 14.1: Internet filtering, censorship, and surveillance

Reporters without Borders and the Open Network Initiative (ONI) both maintain up to date information about global Internet surveillance and censorship. In addition, the following articles are useful for stimulating conversation about types of appropriate and inappropriate content, and whether government control of the internet is appropriate. Increasingly search engines, social networks, and other web sites may also be asked to block access to certain content - either locally or globally. The news articles below provide examples of this type of filtering: The digital citizenship page covers some of the potential legal impacts of online behaviour.

Colour depth and bit depth

Colour depth / Bit Depth

Section 5.5.2 of this long article covers the effect of bit depth on image quality and file size. What really makes this page a great resource is the interactive elements on the page, which let students experiment with matching different colours at different colour depths, and help them to see the effect on the image. A highly recommended resource.
