    Knowledge is meant for sharing. When you learn something, direct someone else to it. I would like to offer my thanks to the designers of the course and to P2PU. You are awesome.

    A big shout out to early adopters and supporters! Unfortunately uploading badges to P2PU.org isn't a straight path. But you get a lot of reputation for being the alpha testers and beta adopters!! This challenge may be big one day when people realize the potentials of 3D Printing. Thanks to you we all are one step closer to spreading this great trade and skill :-) Once we get enough supporters, I think p2pu.org will help us resolve the badge upload task.

    Meanwhile, I am here to help you progress through the challenge, woot!

    Shouting out my support for this awsome challange! A factory of my own in the livingroom building all the stuff I need. We will be consumers of blue prints :-)

    Do you know:

    • If it smells bad from the machine when it´s "writing"?
    • Is it possible to re-use old stuff, grinding it and produce new material?

    :) great questions! Yes, we all love to be desktop creators - The Economist magazine seems to think that will be the 3rd Industrial Revolution. 

    Anyways : 

    1. yes there's a minor smell of working machine (less so of melting plastic - ABS is a common material to use). You can get started by printing elsewhere via online services which are usually higher resolution but also more expensive than home printers in terms of per item cost

    I have a small studio but have been doing well with the machine. I open the window and turn on the kitchen ventilator when I operator it. Goes pretty well. If you have a garage, then you are a big winner

    2. Only costly pro machines are able to harvest used materials. Home printers cannot right now. However, the cost has been dropping significantly 1 kg of ABS spool = roughly $40 dollars. At the makerfaire pros printed 3 days non-stop and didn't run out. 

    Home printers are mostly using plastic variations. Pro printers and printing services allow you to print in metal, alloy, and even ceramics
