Today we're going to be making Agamemnon's helmet, beginning with a staple found in every ancient Greek army's arsenal, a 3D printer.

No, but really, I realized one of my favorite designers, VEC3D, had this model available on their Maker World page, and the accuracy is incredible as always,

so of course I had to make one for myself.

I was able to print the entire cowl section in one piece on my printer.

At first I tried printing the crown part laying like this, but it didn't like sticking to the support material enough, possibly because I was using ABS,

so instead I rotated it more upright, which looks kind of crazy, but it shouldn't result in any more difficult post-processing than my original plan.

This did actually print successfully and overall turned out to be a really clean-looking print.

These main two pieces of the helmet are what I'm going to start working with.

First was removing any support material.

After that, the next thing I needed to deal with was fixing the nose on my helmet.

It printed a little crooked, I guess the support material just had too much give, but because this is ABS I thought

that chemically melting the piece with acetone to try

and reshape it would possibly go easier than trying to heat it up enough to bend it back into place.

Realistically I probably should have just cut the nose off at a certain point,

printed a straight replacement, and stuck it back on the helmet because that would have been quicker than whatever this was.

I did eventually manage to get back to a straight nose with the help of some UV resin as well.

And next is on to everyone's least favorite part of a project, sanding.

To make this process a little more enjoyable I'm of course using my tried and true foot sander,

which yes if you're new here this is an electric foot sander for typically human feet, but you'll never find a better sander for 3D prints.

This print itself was pretty clean so there wasn't anything that I really had to try and sand out to mask.

There were a few areas I had to hand sand, but overall it was pretty straightforward, which means next we can move on to adding some filler primer to this helmet.

This is going to help fill in any imperfections that I couldn't sand out.

I always like to do a couple of layers of this, especially on the raw plastic.

And while I was letting this paint dry, I went back to working on the crown piece to do pretty much the exact same process,

sanding the ABS and then adding a couple of layers of filler primer.

When the helmet part had dried, it still wasn't quite where I wanted it to be in terms of smoothness.

This is a very smooth helmet, so there's really nowhere for imperfections to hide,

so I hit it with a round of 180 grit hand sanding to try and smooth it out a bit more,

and then also did another round of filler primer.

Thankfully after this second round, I was happy with it, but before I add any paint,

I like to sand the filler primer down once again with 400 grit sandpaper.

This obviously is going to leave you with hopefully a really smooth surface to then start adding paint to,

but I also like to do it just in case there's any overspray in sections.

Because of how I want to go about painting this helmet, I first added some flat black primer to the filler primer base.

This might vary depending on how you want to go about achieving the bronze or gold effect, and I'm going to be going over a few different options of how to do this,

but in my case I'm going to have the helmet part and also the crown part both be that matte black.

In between working on those helmet pieces, I also started to work on and print the vertebrae parts.

There are quite a lot of these, and they're also very oddly shaped, so I just decided to resin print all of them.

I was, however, paranoid that I wasn't going to be able to tell the 12 pieces

that go on the top of the helmet apart, so I devised this plan of adding a corresponding number of

heavy supports in a row to the bottom of the parts

because when you try to remove these they will end up leaving little pock marks.

And it worked, although I did realize afterwards

that I could actually tell them apart because they kind of go in size order on the helmet.

Once I had everything printed I then went ahead and cleaned and cured all of the pieces.

pieces.

Because these pieces need to come off as looking like real metal, they need to be pretty flawless surface texture-wise, and where there had been support material attached to these parts,

there was a bit of like an uneven surface texture and pock marks, so I did sand those down a little bit to try

and get them nice and smooth

and then made sure to wipe everything down to get the extra resin dust off

and attach them to popsicle sticks for easier painting.

I'm going to be painting these same way that I'm assuming the real movie ones are actually painted.

The more you get into screen accurate and prop replicas,

you start to realize that literally anything that's supposed to look like metal is all painted in the exact same way, which is, for lack of a better term, the Beskar method.

And that starts with needing a flawless glossy black base.

Because these parts are smaller, I'm just using the Alclad gloss black base.

If If I was planning on doing this to the entire helmet, then I would probably 2K clear the entire thing, which at that point, it doesn't really matter what finish of black you're using

because the 2K is what's adding that really amazing shine.

And once that's dried, it's onto the metallic layer.

This time I'm using Duralumin Tuff.

It's probably actually a Luma Luster, but I tend to reserve that for when I'm actually painting Beskar.

There are a couple of other alternatives, but any of these paints that have metallic flakes suspended in a liquid are the kind

that end up achieving this absolutely amazing metallic effect.

Now, because we do need to dye this in a gold color, I tend to like spraying this a little heavier.

These types of paints are effectively translucent, so you can choose whether you want the finish to be a darker gunmetal color

or build it up to be more of a bright chrome finish.

I just find

that it being on the brighter end of the scale of things tends to result in a more pleasant final result,

unless you are trying to achieve a darker color.

Now normally you would want to set this with a clear coat in between adding the color, but I don't feel like doing that today, so I'm going to go straight in with this alcohol ink

that I like to use that creates this really pleasant gold effect.

You know, it's not too yellow, not too orange, it's just like the perfect gold shade, especially when used in this method.

If you plan on going with this metallic paint route, you will also want to set all of this with a clear coat so that the finish never gets damaged.

I wanted to try out something a little more experimental on the rest of the helmet with using this rub

and buff in quite aptly named Grecian gold over the entire thing.

Agamemnon's helmet looks like it's still supposed to be entirely made of bronze, and then the black color is added over top, which is why the edges are what is gold,

and basically it's from being rubbed off and it's now showing through.

So I wanted to see if I could pretty faithfully create this effect,

and to do that I needed something that paint wouldn't really like sticking to and Rub N Buff, which is a wax paint, seemed like a great option.

Definitely on the riskier side of things since the entire purpose is

that I am assuming that the paint that I'm going to add over top of this is not going to stick well.

I did do a test piece, so this was not me just being a maniac and going full speed ahead on the entire helmet.

It's also just really easy to use

and easy to get this incredible metallic finish without having to go through all of those other steps.

I found that applying this onto the helmet went the best just using my fingers, although you are going to want to make sure you're using gloves because you don't want this paint on your skin.

You really don't need a lot of it, so I was using like pea-sized amounts at a time and just working that all over the helmet.

You could just decide to put this in the areas that you're going to see it later, but I wanted the full effect and I also was concerned

if I only added it in certain sections

that you'd be able to see exactly where it was applied once you start adding the black over top of it.

The only place I didn't touch was where I knew the

vertebrae were going to be getting glued on later just because I wanted to make sure that glue would actually stick,

but I have to say the full bronze Agamemnon helmet is a pretty cool look.

After you rub all the paint on, as the name would suggest, you do need to buff it, so I have my super official t-shirt sleeve cloth that I'm going to use to buff this paint,

which just makes it really shiny.

I had worked in the paint really well to the surface, so it was kind of like half buffed as is,

but this just makes it that it's like a really nice even finish across the entire surface.

And I of course did the same thing to the crown piece.

This time I did end up using a brush so that I could get into those recessed areas along the raised sections,

but I still overall mostly relied on the finger painting technique.

100

And I didn't bother doing the inner part of the crown

101

piece since that's where the plume will end up going and also the bottom since, again, it's going to be where a lot of pieces need to be getting attached

102

and I wasn't sure how glue would react to this paint.

103

I also just wanted to mention, despite covering an entire helmet and crown part in this rub and buff, I think I used maybe 20% of the tube?

104

But now it's on to adding the black over top of this

105

and you really need to be careful when doing this because as I mentioned, the entire purpose of using Rub N Buff is because paint is not going to like sticking to it.

106

I highly recommend you do a test piece to make sure

107

that your particular paint reacts well enough to the Rub N Buff and isn't like a complete catastrophe.

108

That is one of the reasons I ended up airbrushing this black on

109

because I found you really want to be applying the paint in as light a coat as possible.

110

The waxiness of the rub and buff pretty much repels the paint, so you do not want an excess amount of paint on your piece

111

that then can't dry and just creates more of a mess for you.

112

I ended up doing a couple of coats of this black

113

so that there wasn't too much paint on the surface at any given point

114

and to also make sure that the gold was entirely covered and not showing through.

115

When I did my initial paint test, I didn't have an issue using a spray can, but when I tried use it on my helmet, this was the result.

116

I don't know if it was because I maybe didn't buff my test piece as much as my helmet, but whatever the case, clearly the spray can ended up putting too much paint on this surface

117

and it just did not dry evenly whatsoever.

118

So yes, what you're seeing me paint here was the fully stripped, sanded, and re-bronzed version of this helmet.

119

And yes, I still have a ton of that rub and buff left.

120

So while this rub and buff technique looks great and is easier in areas, it is also inherently riskier than doing other methods,

121

specifically when it of course comes to applying this black paint over top of it.

122

As long as you're careful about applying the black paint in

123

thinner coats then I think it might be worth it

124

because it ends up being so easy to make this gold emerge from underneath this black paint.

125

You can just try and scratch it off.

126

I found that in some areas I was accidentally scratching right through the gold

127

and so the best method that i found was using some 70 isopropyl alcohol

128

while it has no issue removing the black paint it doesn't affect the surface of the rub

129

and buff whatsoever like not even the sheen of the metallic

130

which is crazy it does take a little bit of rubbing

131

with something like a cotton swab to remove the paint so

132

if you accidentally get some of the isopropyl alcohol on parts that you don't particularly want the black to be removed on.

133

You don't have to worry too, too much because it does take a little bit of friction.

134

I used the same technique for the helmet portion, although I did start using the middle wooden section of the cotton swab to help scrape the paint off.

135

I just found

136

that the hardness of the wood was doing a really good job at creating nice clean marks along the edges.

137

I'd of course recommend that you look up reference photos of Agamemnon

138

so that you can see exactly where the wear of the black is showing through the most.

139

It is really just on the high points and the edges of the helmet.

140

I know for some people it might have seemed excessive to color the entire helmet in

141

that bronze gold color for how much of the gold actually ends up showing through in the end.

142

An easier method would be to go along these high points with a gold marker,

143

but I really wanted to try out this new technique and also approach this project as authentically as possible, so that's the method I went with.

144

Of course, we now have the slight issue of a helmet with black paint that technically doesn't like sticking to it, so I decided to go over the entire thing with a satin clear coat,

145

which we are again going to want to apply carefully.

146

I know this footage kind of looks horrific with the amount of spray on these pieces, but it does dry okay.

147

The one thing with adding the satin coat is

148

that you are technically mattifying the rub and buff a little it will not necessarily quite have that brilliant metallic sheen.

149

At least on the helmet it's not super noticeable.

150

On the crown piece I did go over the larger gold sections with a little more rub

151

and buff just to bring that shine back.

152

But now it is time to start tackling the plume.

153

I bought a few different options to try and make this, this first one being this actual Trojan helmet plume.

154

This was not nearly going to be enough hair for this helmet though, so I also picked up these carpentry brushes that looked promising.

155

They had much longer bristles than a lot of other paint brushes and more hair-like bristle things that I could find.

156

I mean, I did pick up a couple of brooms to try, but they were too plasticky because ultimately this does need to at least mimic horse hair.

157

This plume was really nice, but it was absolutely not the right curve, which is why I'm dismembering it.

158

I'm going to be using all the hair though in this printed piece that is what actually sits within the crown.

159

There are a couple of versions of the model.

160

I went with the one that has the holes in it

161

because I figured it was going to go the best

162

if I actually stuck the hair in these holes to create this plume.

163

So the plan that I came up with, at least for mine, was to use this nicer hair around the outer edges of the plume,

164

extra in the front, and then to take apart this particular carpentry brush

165

and use these tufts that you can basically just pull out of it.

166

They're stabled in place.

167

But use these thicker, stronger bristles within the middle section of the plume.

168

They were going to take up a lot more space.

169

You also weren't going to really be able to see them

170

because the edges were going to be covered by the nicer hair.

171

Of course, these were the wrong color and I needed to dye them.

172

For this, I just used some leather dye.

173

It's what I had around.

174

It does seem to have worked.

175

I don't know if it would hold up to a rainstorm, but I also don't plan on having this helmet leave my home.

176

And I of course dyed a lot of these little clumps, but it was really handy that they were already in these sections of hair bristles,

177

whatever we want to call these.

178

I ended up just closing the staple around the bundles to keep all of the bristles in place, and I didn't bother trying to stick these in the holes themselves.

179

I just hot glued them onto this inner plate.

180

For the outer sections, I was really careful about trying to have there not be any glue visible,

181

so all of those little tufts of hair actually went within the holes on the plate.

182

And I have to say, this plume making process is not for the faint of heart.

183

I spent more time on this blasted piece of hair than I did the entire rest of the helmet,

184

even when I had to strip and repaint the entire main helmet piece.

185

So I was very happy to see this done.

186

Before installing this into the crown piece, I decided to go ahead and install the vertebrae.

187

I figured it was going to end up being easier

188

if I did it in this order so that I didn't have to deal with the hair sticking out of this piece.

189

Now, I know I showed the entire process of painting these earlier, but I didn't think about the fact

190

that they were going to be sitting under something

191

that was painted using an entirely different product and have a completely different finish, and I didn't like how much they didn't match.

192

So I went ahead and added some rub and buff on top of the gold that I'd already painted, which did mostly work.

193

Obviously, I wouldn't go out of my way to do the one technique and then add that over top normally, but this did save the color matching issue that I was having.

194

Back to the actual plume though, I ended up adding some extra hair onto the front of the crown piece just

195

because how I wanted the insert to be sitting, there needed to be some more hair in the front

196

and I also needed it to be as long as it possibly could be.

197

I ended up hot gluing this into place, but that's what we're working with.

198

As you can see, I did leave the one end short hair

199

and that's because I knew I was going to need to trim this.

200

I didn't want to waste full lengths of hair on the back of the crown, but it also gave me a good guide of the lengths that I needed to blend together.

201

Obviously being very careful since I can't miraculously add length back onto this if I accidentally cut it too short.

202

In general, I also just needed to trim and try

203

and make some of the hair tufts more even since they were in like a million different tufts of hair

204

and they weren't all necessarily sitting at the same length.

205

But here is how my finished plume turned out and now is on to attaching this to the helmet.

206

I just used some super glue for this.

207

Some of the vertebrae have tabs that sit within the indentations of the helmet, so that's how you line it up.

208

But we are still not done with the hair work on this helmet

209

because next we have to deal with the ponytail and the vertebrae that go onto it.

210

I bought this ponytail extension since it wasn't very expensive and also in general just seemed perfect for this application.

211

It has this piece of velcro at the top

212

that I ended up connecting it onto itself and creating this roll that fit absolutely perfectly within the hole on the crown.

213

This ponytail is way too long and also way too thick at the bottom for the vertebrae to fit onto it.

214

There's quite a large size difference between the largest and smallest vertebrae that needs to go onto this ponytail.

215

So I thinned out the bottom section and I also knew I was going to need to pad the upper section.

216

Literally half of my time on this ponytail was spent just

217

figuring out how on earth I was going to get these vertebrae onto it

218

because shockingly not a lot of experience in that department.

219

What I ended up doing was feeding on all of the vertebrae

220

that would actually fit onto the ponytail as it was and of course they ordered they needed to be in.

221

Next I glued the ponytail onto the helmet which was extremely nerve-wracking because there was no going back from this moment.

222

Because of how I took the ponytail and wrapped it around itself, it created this sort of tube of hair that I started to stuff with those foam pieces.

223

And then I would slide back up the various vertebrae in place

224

and then continued to stuff them so that they would actually stay where they needed to be.

225

Do I think this was the best method?

226

No, probably not

227

if you were planning on making this for cosplay then I would definitely suggest finding a more permanent and strong solution,

228

probably looking up various anime wig techniques, but this was the best that I could come up with myself after like a 14 hour day spent on that plume.

229

The bottom of the ponytail was once again another problem I needed to solve.

230

On the thickness of my particular piece of hair, I could fit the top five vertebrae, but not the bottom three.

231

So I ended up using a combination of some glue to try and keep the hair down and in place,

232

and also some cling wrap to try and keep the hair nice

233

and smooth so that I could slide these vertebrae on easier

234

and just in general be able to get all of the hairs through them.

235

Again, not a perfect solution.

236

Somehow it did end up working even though removing the cling wrap was an entire other problem.

237

After I miraculously managed to get all of the vertebrae on, I did end up trimming the ponytail down to the correct length.

238

The last thing I did was weather these vertebrae parts with some brown and black paint.

239

Really nothing too dramatic, just a little hint of color in some of the recessed areas of the vertebrae

240

and around some of the under edges.

241

It just helps to sell the idea that this is a helmet being worn

242

and of course there's going to be some dust and dirt accumulate in these various parts.

243

And here is the finished Agamemnon helmet.
