HL2 The Borealis (Aperture's Healy-class Icebreaker)

"It's... the Borealis?""Good god.""What? The Borealis? It's real?"Well it sure is now.More exactly the version seen in Half Life 2 Episode 2, which is heavily based on the USCGC Healy icebreaker instead of the Polar-class ones.I suppose it's not a too far fetched idea that Aperture acquired the ship at some point and made extensive modifications to it for the teleportation experiment. Since we never see the rear of the ship, nor was it ever defined by Valve, I've extrapolated what could've possibly been there. That includes two smaller Enrichment Spheres on top to house two black holes and an Aperture themed landing pad at the end, along with some brand containers seen on deck and a different crane layout.And of course the ice mountain it ended up inside.The rough scale of the model at default size is about 1:620.Imgur album with more project photos.I've also used a few other models to aid in the making:Small compressed Titanic and scale example of the iceberg as a base to work from for the terrain20ft shipping container model as the Aperture Laboratories containersBoat Propeller for 8 mm diameter shaft as the two ship propsPrint SettingsRafts:NoSupports: NoResolution:VariousInfill: 7Notes:Printed everything at 0.12, except the propellers at 0.08, guardrails at 0.2 and the terrain at 0.32.I've exported several options for printing:borealis_extras_ship_and_terrainThe entire thing, more as a reference.borealis_*Theintended way to print it, with all parts printing supportless and most in best strength configuration on FDM.Terrainborealis_iceterrainAbove waterlineborealis_mainbody (ship hull without details)borealis_guardrail (print multiples of these, cut them up and glue onto the ledges around the ship)borealis_gantrycranes (add the large one to the very rear of the ship and two to the side walkway below the funnel)borealis_cranes (two on the front deck two on the rear deck)borealis_mast (glue on top of the bridge)Below waterlineborealis_keelborealis_propellers (print with a brim, glue to borealis_keel behind rudder)borealis_extras_shipThe ship with full details if your printer can handle it somehow.Print separately:borealis_iceterrainborealis_extras_ship_no_keelSame as above but without the keel, for suportless printing at least on the main hull level. Details are on but will need supports and will likely be very fragile.Print separately:borealis_keelborealis_iceterrainPost-PrintingIce TerrainPrinting out the terrain with white filament works well enough, but I've attempted an interesting technique which turned out really well, and it goes a bit like this:mix wood glue with a dark cyan shade of paintapply with brush onto terrain, making stabs to get the sharp texturewait till dry, then repeat with lighter tones (I made 4 coats total: dark blue, light blue, gray, white)after the last coat dries paint the white parts with white paint directly to have them appear more matte (snow isn't glossy)And that's pretty much it.LightingSo I didn't really design the model with lighting in mind (to have it print as a shell I mean), but was something I attempted afterwards.Anyhow the process was along the lines of this:use black PLA as it has lots of pigment and doesn't let light through as easilyprint the main body and keel sections without bottom layers (or without infill and replace it with supports if your slicer allows that)clear out infillpaint both sides silver, as the reflectivity tends to stop light bleedpaint and weathering the pieces separatelydrill out holes (or in the case of square ones, get a square file, heat it up and melt the opening, I don't see how one can cut out that shape at this scale otherwise)add hot glue to the inside to diffuse the lightplace led lights behind the glueA better method would involve using optic fiber filaments to get best results with the round windows, but that's far more tedious.DecalsThere is an enclosed decals.pdf which contains an example of the Aperture Laboratories logo for the containers.I would suggest printing it on A4 cardstock, then gluing it to the containers with superglue. There are a few sizes of decals in case any of you decides to print in other scales or print on other paper sizes.
