I'm not a 3D Printer person, but am always interested in what others are doing. Today, I noticed an article about an 83 year old gentleman who designed a $250 filament extruder, which means he can make his own filament to use on his 3D printer. Did I mention he won $40,000 for the invention. Oh, and did I mention he has make it all available to the world if anyone else wants to build their own.

Here is another forum chain that I have monitored and contributed to. It is the thread on building an extruder.

It is 39 pages long but has some very informative info in it. Here is the first photo from the thread


Here is a photo of the filament that the lead person "elmoret" made using the "Filastruder"

He made everything but the blue filament.

How uniform is the filament?
