The most practical application is probably building parts for my robots.

i really just find it extremely cool, but i guess it could be used for replacing parts of household appliances.

I have several ideas that I would like to flesh out so prototyping is my most practical application. Once you have a 3D printer its easy to do 8-10 iterations of an idea to really refine it.

Being a beginner I am exploring the production of component parts to create larger useful items for myself and others.

This would help me realize a myriad of projects and ideas I have - turn me into a Maker

Prototypes for custom motorcycle components as well as industrial part fixtures.

I love being able to customize all my stuff down to their structure! Which is why I'd like to have a personal 3D printer, there's a (self-imposed) limit on what I can do with a printer that isn't mine.

[CVanSteyn]

I would use the printer as a tool for prototyping small intricate parts for my motorcycles or building brackets for smaller objects.

[ralphzoontjens]

I mostly use my 3D printer to create research prototypes as I am a product designer.
I also explore a lot with different materials to learn about their possibilities.
I have also created several customized items for end use, including jewelry.

Sparking my kids imagination in tech. Allowing them to see it not just for the tech but how it can be used. (100 glitter ponies will probably come out of it but what follows the realization of the potential it presents is where the true value is)
