About the Project

I decided to join the fun this year as well, even with failure of last year project which still isn’t finished. First, couple of words explaining the title. The project is about building and painting (and narrating history) of Pathfinder Chimera class spaceship designed by 2nd dynasty and funded in Kickstater campaign some 18 months ago (IIRC). It is now available for purchase on Myminifactory page (address in first project entry). Now, the ship is extremely blocky, true glorification of the shape of a brick. Since I’m old enough to remember the 80’ as it was yesterday, it instantly brought Volvos 240 and 740 to mind. Those glourios Sweedish cars were designed using only one tool: setsquare! Since designer of the model is Australian but lives in Sweden (!!!) there was no way back from association. For me the Chimera class and Chimera Subclass were all designed by spaceship architects from Volvo Heavy Space Industry PLC and built by shipyards owned by that company or working on its licence.

Progress report 10.05.2021

 

I had a week off, but then I managed to push the work quite a bit further.

Pictures bellow tell whole story of pre-shading and applying final colour of the fuselage.

This is where I started. To this point the ship was covered with spray-paint, and I painted landing gear wells with dark metallic from Army painter.This is where I started. To this point the ship was covered with spray-paint, and I painted landing gear wells with dark metallic from Army painter.
Next, I grabbed Valejo sepia ink and traced all the panel lines on the fuselage (with airbrush of course). It is good to be as neat and tidy with this step as possible, to save time in next steps… I wasn’t and paid for it later.Next, I grabbed Valejo sepia ink and traced all the panel lines on the fuselage (with airbrush of course).

I think, lost one photo somewhere. Next step was to accentuate centre of each panel with white ink. This is where I had do spend additional time tiding speia lines.

In this photo you can see, that I covered whole thing with transparent layer of white ink, that was done to bring the colours a bit closer together.In this photo you can see, that I covered whole thing with transparent layer of white ink, that was done to bring the colours a bit closer together.
And finally, I switched from my small airbrush to my Chinese blaster of doom – a syphon fed .8 mm nozzle murder machine. I painted couple of layers of Vallejo white wash and transparent raw umber ink (roughly 4:1 mixture).  Final step was to cover it all in solid layer of Pledge floor polish. Now the ship Is ready for decals, which unfortunately I need to design first… That’s the next step on the agenda.  And finally, I switched from my small airbrush to my Chinese blaster of doom – a syphon fed .8 mm nozzle murder machine.

I did quite a lot of work last week, but don’t have much to show for it (photo-wise anyway). I’m only two build plates away from having everything printed out and I painted all the shell (inside and out) with the spray, I skipped the gesso on two lower decks as it wasn’t playing nice with tolerances of the model.

Just one quick photo:

Well, printing is progressing steadily, but I had some stupid misprints – like the one where I put draining hole ideally on the same level and it was enough for the peel forces to tear the model in half…

Also I need to limit final curing time, because the resins tends to get too brittle and break while I push the connectors in…

Also, we had beautiful day today so I painted the outer shell of the top deck.

First I applied a layer of gesso to even out the printing layersFirst I applied a layer of gesso to even out the printing layers

I compared whatever pictures of the Chimera Pathfinder I could find with parts I had printed  to date. I came to some conclusions on what I still need to print. Bellow you’ll see visualisation of what is needed in case I decided to print original arrangement of the interior, I’m still not certain I want to.

This is original design of the interior according to the printing instructions and reference found on the Internet. This is original design of the interior according to the printing instructions and reference found on the Internet.
I'm missing parts coloured in red... that's more than I was prepared for. My estimate is that it will take around 70h of straight printing time to get to the end of the process, that doesn't cover time required for preparation and post-processing. I need a week of good (warm) weather. I'm missing parts coloured in red... that's more than I was prepared for.

True to founding idea of Spring Cleaning Challenge, my project is ongoing for quite some time, at least a year.

That means on the one hand, that I have some work done, and on the other that my initial enthusiasm has already burnt out.

Therefore let me start with a bit of inventory:

 

 

The outside shell is almost entirely printed. It lacks some antennas in the sensor suite and maneuvering thrusters. Also I’ll ned to reprint two big parts near the bow of the ship, since what I have now doesn’t have thrusters’ mounting.The outside shell is almost entirely printed.

Lower deck doesn’t have any internal details printed, and more than that, I need to thonk what I want to put there, as I’m sure I won’t be installing all those hibernation chambers the original design suggests.Lower deck doesn’t have any internal details printed, and more than that, I need to thonk what I want to put there, as I’m sure I won’t be installing all those hibernation chambers the original design suggests.
Mid-deck. Bridge is ready for painting, and next room which is med-bay starts to take shape, however, this deck is full of intricate details and will take some considerable amount of time to print.Mid-deck.

Top deck. All the internal parts are printed and some even have primer on them already. I may still change how the rooms are arranged, but I’ll write more about it in one of the next entries.Top deck. All the internal parts are printed and some even have primer on them already.

It may look as I’m missing one engine. What actually happened is that while taking the pictures I dropped the model and It smashed a plastic ring which holds the engine and fuselage together. It is repaired already.It may look as I’m missing one engine.

And this is how it is supposed to look in the end, at least when in terms of shape.  And this is how it is supposed to look in the end, at least when in terms of shape.

As for technical side of things; all the external parts, most of the floors and bunks on the top deck were printed on my Prusa I3 mk3 at .15 mm layers with 15% infill, with exception for bunks which have varying layer heights from 0.15 to .3 for speed. I used Amazon branded filament and Prusament (both PLA of course).

The parts printed on SLA printer (Elegoo Mars) are printed on normal setting so .05 mm layers, Elegoo resin, some translucent and some grey.

 

You may also notice that I have cut out detailed parts of bulkheads and printed them on SLA while rest of the part was printed on FDM.

 

Oh, and the model can be purchased HERE.
