This is not an entry level 3D printer, so if you are new to the technology you will likely frustrated by this product. However if you are a Maker with RepRap experience and are seeking a mechanically solid machine with 125 micron layer build heights (and you have a fat wallet) this is a great machine. Note, this is not an open source machine so if modding is your game stick to the RepRap world. But if you want large build size, fine layer resolution (for today) and solid mechanics, if you are ok being tied to 3D Systems proprietary world.This is not an entry level 3D printer, so if you are new to the technology you will likely frustrated by this product.
