Let's Make Robots!

Cnc or 3D printer?

So, this is my problem: Which one should i buy? Tell me pros and cons, like price and complexity. Some of you have knowledgement with these things, and these guys know a lot of these things. But most importan thing: I need something affordable and it can be used to produce robot parts Thanks, BotFIN

  for me the idea of   creating one of  prototypes from plastic  for robots is what tugging me towards  3D printers and they are becoming so affordable  been studing this one http://www.nextdayreprap.co.uk/prusa-mendel-kit/ should fit well in the small work space i have. first task will be to print replacement parts " just incase ". where with the cnc mill you need the  bits, possible coolants ,noise ect. if you ever need a aluminum part  you could always bug chuck to make it for you...

I would suggest a 3d printer. Simply because a printer can produce more complex parts than a similarly priced mill. For comparison, ChuckCrunch bought a cnc mill for about 1500. He has more X and Y travel, but, his Z is only 50 to 75mm. With a printer, you can print some pretty intricate parts that a 3 axis mill just could not manage. However, you will not be producing the beautiful aluminium parts that Chuck is.

CNC pros . not restricted to just plastic . wood, plastic, aluminum, ect . also PCB's and engraving  , lager bed size

CNC cons, waste lots of materiel, mill ends brake , not very clean , depending on your spindle can be very noise 

3D pros, i don't have one so no comment    

maybe a laser cutter is something you may look into as well

Sorry about that, my keyboard isn't fine!
