When do you think 4-D printers will be available to the public? Also, how much do you think they will cost?

What's a 4-D printer? There are three physical dimensions plus time.

If you mean 3-D printers, devices that make physical three-dimensional objects under computer control, those are available to hobbyists now. They start at about $2000, so its for serious hobbyists. The work by feeding a strand of plastic through a print head that melts the plastic and deposits it on a structure that's being built up. Only plastic objects can be printed. A mold can be made of the plastic piece for use in casting a metal or ceramic version.

Amazon sells 3-D printers and supplies.

Hewlett Packard bought a 3-D printer company earlier this year. That's a clue that the technology is moving towards mainstream use. We'll see.

How would they work? There are four dimensions - three spatial (all three of which are in use for 3-D) and one time. Would that mean the object I printed could be created at a determinable moment in time.

Technically current 3-D printers make objects that vary over time, starting from a single location and growing into whatever its final shape is. So 4D printers are already available to the public for as little as a few hundred dollars

While correct, there is a difference between the set amount of time it takes to make the object, and the user being able to put in at what time that object will appear. I could make an object after it was created with a 4-D printer. You couldn't do that with a 3-D printer.
