Still building mine currently.
Printed in PLA
Joined hull pieces for less work.
Split the deck into 3 pieces
Also created a rear deck hatch
sealing with XTC 3D
I joined the hull with super glue gel, then took a soldering iron to seam it. priming, sanding, etc
Printer: creality cr-10 300x300x400
supports: yes (note: I used Simplify 3D to build custom supports, 30% infill @ 20mm square and made a few of them so they wouldn't fall over)
print time: 54 hours for half of the hull
