How useful is a 3D printer?

[cropwell]

Funnily enough, when I told a friend I had bought a 3D printer, his first reaction was "What the hell are you going to use that for". Before I left his shop he had asked me if I could print a cup to fit in the drinks holder of his Jag, to keep coins in and a bracket for his powered wheelchair.

I have used the printer for all sorts, from cases for equipment to an alien plaque for a sculpture. I have printed a lithophane of my son and his new-born daughter.

What you can do with a 3D printer is limited by the build envelope of your machine and your imagination.

I build all sorts of things for all sorts of things.!!
I use them to make covers, limit switch brackets, terminal boxes, Motor covers, etc and even Motor mounts on some machines I've built. They are great for proto typing parts for checking fit and looks etc.

I build jigs using them and all sorts of things little things that you wouldn't other wise bother making because not simple. Provided your handy with Cad then it's simple with 3D printer, just hit the go button and walk away, several hours later you have ready made parts.
