3d printers i'd like to know

[Wodahs]

I am interested in what I hear about 3d printers and one may be of some use to me in one of the industries im involved with

so if you have any info on them or have used them please flood me with all the info

including useable medias and other options with them

I have dealings with restoration and customizing of older vehicles and some parts are getting harder to come by and whats out there can be hard to repair or revive

so pending on the medium useable and size of printer (and well of coarse price) one may be handy for this area but effectively the print bed would need to be at least in the size of (metric) 1.5mtr x .5mtr x .5mtr or (impiral) 5ft x 1.5ft x 1.5ft or larger
