RoboCop Casemod - ED-209 by RandomDesign

[RandomDesign]

And now for another mod.

I worked together with the company Nacon to create a mod that

should promot the upcoming Robocop game. So I decided to build the ED-209 from the original movie.

 

The mod already was shown at gamescom. Unfortunately only in the business area.

Now I got some time to finish the rest of the work and start the worklog already.

 

I got some renderings from the video game.

 

 

 

 

I took them as a reference to creat my own version of the ED-209. Many parts will be 3D printed,

but others will be molded and cast in resin.

 

 

 

 

 

Cause this specific version will be raffled away, my wife got the idea to directly build a version 2.0

once this project here is done. Already got a long list with improvements and changes I want to make to this one.

 

But first lets finish version 1.0

[RandomDesign]

Then it was already time to start.

 

I have worked on multiple pieces at the same time, but I will try to

organize the pictures as good as possible.

 

Sterted with the feet that are mainly printed in PLA.

 

 

To reduce a little bit of the weight, the front and side pieces of the foot will be roto cast

later, but the template is printed in resin.

 

 

And most of the parts were done.

 

 

Most of the parts from the leg will be attached to an inner core that will hold all the weight of the mod.

Inside the inner core, I already included all the holes for the mounting. Will have more detailed pictures later.

 

 

 

Then I started sanding down the layer lines in my PLA prints. I also gave the resin parts a quick sand.

Even if they are printed in resin, a slight sanding will really improve the later apperance.

 

 

[RandomDesign]

And here is a picture of the two parts of the inner construction of the leg piece.
They will be just pushed onto a 2x2 cm aluminum profile. This already holds up püretty good,
but I also included two 6 mm threaded rods just for a better mounting.
This way, I dont have to glue any parts, but could theoretically make changes or take
everything apart if needed.

 

 

 

Then I printed all the pieces for the outer shell of the leg.

 

 

First sanded everything with 120 grid sanpaper and then glued all together.

 

 

 

 

Smaller parts were printed on my Prusa MK3S and the larger ones on my Elegoo Neptune 3 Plus.
The Neptune is a decent printer for the price, but the parts need more post processing than the Prusa ones.
All the larger gaps were filled with Miliput, a two part epoxy putty.

 

 

 

 

[RandomDesign]

Unfortunately, I just realized now that my camera messed up
the white balance in some images....

 

After the main construction of the leg was done, I started with the detail parts.
Working on this little part on the top and bottom side of the leg.

 

 

As I need most of the details multiple times and also in more or less the same look.
I decided to make mold and cast them in a cold-cast technique. This way, I will save some time
in the Post processing, and all the metal parts will have the same look.

First, I printed both parts in resin. This alone saves a lot of time in post processing as resin
sands much better than ABS or PLA. Also much less sanding is needed.

 

 

 

 

Then I built a simple card board mod box. I used Mold Star 30 (not 20T) as my silicone.
A simple one part mold was more than enough for this simple piece.

 

 

 

 

For a cold cast, you first need to dust the mold with some metal powder brfore pouring the resin in.
I used Smooth-Cast 305 for most of the pieces.

 

 

The cast parts looked a little dull right out of the mold. After polishing with some steel whool
all was nice and shiny.

 

 

 

A quick weathering with a brown and black wax followed.

 

 

 

[RandomDesign]

The next detail were also first resin printed and processed.

 

 

Cause the back side of this pieces was important, I needed to make a two part mold.
First I made a clay bed and layed the pieces on top.

 

 

After the first half was done, I simply needed to spray a mold relsase on everything and
made the seconf half.

 

 

And the entire mold was done.

 

 

The larger detail parts was just cast in normal resin. The smaller parts were cast again with a cold cast technique.

 

 

 

[RandomDesign]

Next, I worked on the mid sectinn of the leg.

 

 

First all parts were again printed.

 

 

 

I needed the cover on the side 4 times in total in metal optic. So I made a mold again

and did a cold cast of all the pieces.

 

 

 

 

While working on some parts, I realized that the back part of this section needed a very long time
to get sanded down. So I made a little adjustment and printed that part also in Resin instead of PLA.
That way I yould make a hollow cast of this part. UNfortunately, I missed taking some pictures,
but I have some showing the process in a different section later.

 

 

The next part, I also needed 4 times again, so I made a two part mold and cast everything.

 

 

 

Again polished the cast pieces with some steel whool.

 

 

[RandomDesign]

Over time, I got quite some parts on my workbench.

 

 

Luckily, I could print the arms as one piece on my printer.

Minus the details ofc.

 

 

 

For the rocket launcher of the right arm, I combined PLA and resin printed parts.

 

 

 

The three cannons also have three magazins on the bottom part of the arms. To reduce weight and to fit the
desig, they were also cold cast, but hollow.

 

First, I prepared the master.

 

 

 

 

I used Smooth Cast Onyx Fast, cause it only has a 3 minute pot live. Hat gave me enough time to poure it into the
mold and rotate it to get the resin on every spot on the inside. After a partial cure, I repeated the procedure
to get a little more thickness for the walls.

 

 

[RandomDesign]

To attach the arms to the main body, I printed some kind of ellbow.
The holes are later used to incert a metal rod for stabilization.

 

 

Cause the resin parts were too brittle, I decided to also make a mold and cast this section.

 

 

 

 

Already predrilled the holes for all the screws and metal rods.

 

 

Then, I could finally start building the "head" section. Just needed to cut it down
to 4 pieces to fit on my printer. Makes filling a little easier.

 

 

 

For stabilization, I glued two aluminum profiles to the inside.

 

 

To further strenghten the section, I applied an epoxy coating to the inside.

Fantastic!  Get this moved to Build Logs so it's archived with the others.

 

Love it!

After all parts were post processed, I started with the priming and paint job.

 

 

I went for a slightly darker grey tone then in the original, just to make the metal detail pop more at the end.

Some parts also got a small darker details.

 

 

 

 

After everything was primed, the weathering with black and brown colors followed.

 

 

 

Everything was still a little too bright. So, I went over each part with a dark black/brown wash.
This also helped ti really tie together the weathering affects applied before.

Dude, seriously this is coming along beautifully!

Thanks mate! Have a couple more posts before the final pictures.

[Dedayog]

Do you have a website?  I assume you do this for a job too?

[RevGAM]

Wow! You are so patient and detail-oriented! I'd go nuts doing that!

Here you go: https://randomdesign.org/
Yes, I am mostly building mods and props for all kind of clients.

Who said, I didnt went crazy already
 

 

While the paint and clear coat was drying, I finished casting the last detail pieces.

 

 

 

 

All metal parts were then hit with a layer of brown and black metal wax for a suttle weathering effect.

 

 

 

Quite some parts.

 

 

Next, I sanded down some black screws and glued them in to the some holes of the detail parts
to create an even more mechanical look.

 

 

 

[RandomDesign]

Finally, it was time to bring everything together.
Started with the back of the leg. All parts are glued and further stabalized
with some metal rods.

 

 

 

For the rail parts, I didnt used any glue, but simply put them into place.

 

 

 

After the first parts were put together, it showed that it is quite a complex build.

 

 

Next, I started combining all the pieces for the weapon arms.

 

 

 

[RandomDesign]

Next, I needed the elbow part that holds the weapon arm.
I glued the 3 resin cast parts together and stabilized it with an aluminum rod
inserted in the middle.

 

 

 

 

The weapon at the front end was simply resin printed and colored black.
For a little metalic effect it was dry brushed with some silver paint.

 

 

And the workbench was full again.

 

 

Then the assembly of the legs followed.
To hold everything, the core was made out of a 2x2 cm aluminum profile.

 

 

Every part was slided on the profile one by one.

 

 

 

Then I made the first real test assembly on a ply wood board.

 

 

 

Then I built in the hardware. Unfortunately, I dont have pictures of that, but its not really spectacular.
Next, there will be fome final images.

Stunning so far!  Inceedibly well thought out, and it's coming together gorgeous!

 

You make the CL4P-TP as well?

Built the CL4P-TP as a female version a couple of years ago in a 24h live modding challenge with my wife at gamescom.

Thanks mates!
Yeah in terms of amount of detail work and used materials, this one was definitly my biggest so far.

As for my version 2.0 I am already planning to include some LED effects in the weapons and maybe also a smoke effect, just like in the office scene from the movie.
Also some detail parts need a little adjustment. Specially for the black cover, I want to try and replicate what looks to be some kind of mesh structure.

Then, I already have another build which I already started some of the 3D modelling. Just need time haha.
