See the more detailed build log at: http://umforum.ultimaker.com/index.php?/topic/1877-e3d-all-metal-hotend-for-ultimaker/page-4 *General update after months of use:* I initially printed this in PLA, expecting to eventually replace it with a material that can withstand higher temperatures. However, the original head has held up perfectly with no noticeable changes anywhere - it has also performed well during long prints at extremely high nozzle temperatures, including 6-hour prints at 290°C. Now, I see no reason to print this in any material other than PLA. Print each piece on a slow, cool, high-quality setting without support. The main printhead body and the clamp piece should be printed in the same orientation they will be used in the machine. The main printhead body requires some manual correction of curling (flattening edges with an X-acto or similar) during bridging of the active cooling fan duct, but after that, it's all smooth. The print fan duct should be printed with the fan mount side touching the bed.
