id="article-body" class="row" section="article-body"> 3D printing, like virtual reality, is one of those technology things that always seems to be on the cusp of going mainstream -- without ever quite crossing over. Even though we've seen the concept play out for years on TV and in movies (what do you think a Star Trek replicator is doing?), having a 3D printer at home is still considered wildly exotic outside a small enthusiast audience. 

Last year, I started playing around with 3D printing, less commonly known as additive manufacturing, mostly to satisfy my own curiosity, with an unexpected result. I'm now completely addicted to 3D badge printing London. Over the past several months, I've searched for the best 3D printer technology and tested several 3D printing models, from rock-bottom Monoprice printers to step-up resin printers that produce a truly professional-level print for prototyping. 

Below are printers in the lower-cost price range that we tested in the CNET Labs, and close-ups of one of our comparison test prints, a bust of Abraham Lincoln. All 3D prints require a little smoothing and filing with a hobby file to look their best (you can also prime and paint each print, fill gaps with filler compound and so on) -- but the Abes presented below are right off the print bed, no touch-ups after the printing.  

One printer I have not tested yet, but hear a lot of good feedback about, is the Creality Ender 3, which currently costs an affordable $230 and has a large community of dedicated fans who claim it's the best 3D printer. Just note that some more assembly is required than with these other printers.
