So, how does 3D printing work?

Dagbah

Today, I watched a YouTube video by ASAP Science and they were discussing about 3D printing. I got really interested and I wanted to know what can you do with a 3D printer. I know you can obviously print out things in 3D physical objects, and the only thing I've really seen people print out are things like dishes, etc. Can you print out other things like... let's say a phone, clothes, shoes, or even a human being? Respond quickly! Thanks :)

Answer
the current 3D printing technology is limited to Plastic items, there are some '3D food printers'

your really only limited to printing what is availible online, you have to first have a 3D image of what your wanting to print which a lot of people are using 3D scanners and uploading plans and making them availible for others to use.

you cant print phones, but you can print covers
no cloathes
no shoes
no humans/animals/living beings.

how to create a 3d model of a guitar?

Paul

i want to create a 3d model of a guitar. what ways are there to help me create it with the software i have, as in importing photo files or a scanning the guitar itself?

Answer
if you meant to design 3D guitar on computer, you could simple collect measurements and re draw image in 3D editor like Sketchup

could be use to take photos and place visually into rendered object of guitar body

if you meant to actually make model as life size copy,
that would require laser scanner and printer
