Portal II: Aperture Science Sentry Turret

[Yaan]

Hi.

I am currently buliding a "prop" from one of my favorite games: PORTAL. The game features some funny sentry turrets, i like the design and i found it on thingiverse.

The design i am using was made by "swesen" Linus Boreus from Sweden - Portal Aperture Science Sentry turret by swesen

I am trying to learn some new techniques, i am especially new to 3D design and printing and painting as well. Just got a new printer and will post as i go.

I made some really bad screenshots and tried to gather some information about the coloring and details:

Luckily i found a complete 3D model directly from the game, so i could get a much better view for the details:

So, this is the look i am going for. I am planning to make a "like new" version and a weathered, "used" version.

I am still trying to get the right settings for the printer. This is a tedious process, as you change the settings, print a testpattern and look for the right results, print again and so on. I already found a very good resin, which works best for me but obviously, there are slight changes from different production charges. So you have to tweak the settings a bit.

I scaled the original model to 60%, this is the biggest i can go with my current printer. You could cut the model in smaller pieces, but you would have to glue the parts together again. Getting good transitions with minor rework is hard to achieve, and you would have to use putty.

The round "eye" is about 14mm in diameter, the resolution of the printer will definitely do the job, as there are no highly detailed parts in this build.

Here you can see the layer lines and it seems like the printer did a little shift, so this has to be sanded down.

Cool project.
I've seen a few people make them over the years.

Don't know if you saw it but JakeySnakey630 has been working on one that will be fully functional.

Couple reference pix for you.

Thanks alot for the pictures. I did see the functional turret from Jake - awesome.

I ran into another issue with the resin printer:

It needs a lot of supports to print objects really straight. I might fix this - more likely i will print another set and try to
print it directly on the bed surface, without supports.

Most parts came out excellent.

Printed parts mostly done, antennas bent. Next need to sand all parts to prepare paint...

I added some greeblies for some details - this is for the "weathered" version. Thinking about going with a darker color for the other version.

Using resin to glue the parts. This is getting me pretty good transitions, tried superglue first but this works even better.

Testfitment for the weathered version, the middle part is pretty warped, the shell isnt.

Trying stuff for the "fusion core" and machine gun compartment with waterslide decals:

This is the reference, i took the original texture file from the game:

Awesome project! Excited to see how it comes along!

Last week i wet sanded some parts:

And i made the slots go through:

Finally my spray cabin showed up so i could lay some color:

I am really happy with the result so far, this should have been the version i planned to weather and make it a bit battle damaged. I`ll see.
