3D Printer

It is true. 3D Printers are starting to get better and better. As the comic suggests, just don't put them online like fax machines.
In the image text, Better Homes and Gardens is an American magazine that as the name suggests, shows you how to make your home and garden better.
Also in the image text, acrylonitrile-butadiene-styrene or ABS is a light-weight and moldable plastic which makes it perfect for 3D printers.
Headache

This comic is about 10 images so that it can present the 3D effects, so head over to xkcd if you have not already to check out the comic with the 3d effects. (UPDATE: I have placed a screenshot above.)

This comic is probably a reference to the new Nintendo 3DS handheld video game system that has a 3D effect if you put your head in the right place for the handheld device. Also, it is a reference to the proliferation of 3D movies. The 3D movies and 3D games make your eyes work harder which can cause headaches in some.
In this comic, Cueball is using the excuse that 3D gives him a headache to get out of going outside, where obviously, everything is in 3D. Instead he stays inside and looks at his 2D computer monitor. In the image text, he says he will only go to places with little 3D motion.
On a side note: Megan is wearing her helmet and practicing safe bike riding. Way to go Megan!
UPDATE: Thanks commenters - because today is April 1st, all of the xkcd comics are in 3D, so go back and check them out. Which one is your favorite in 3D?
