You’re standing in the toy aisle, staring at a wall of plastic. Maybe it’s the hundredth Batman repaint or a background character from a show nobody watches anymore. You think, "I could do better." Or maybe you just want a figure of yourself, your D&D character, or your dog in power armor.
Making toys isn't just for Hasbro anymore.
Honestly, the barrier to entry has absolutely cratered over the last five years. It used to be that if you wanted to know how to create your own action figure, you needed a degree in industrial design and ten thousand dollars for an injection mold. Now? You just need a decent resin printer and some patience. Or, if you're old school, a bucket of boiling water and some spare parts.
Let's get real about what this actually looks like in practice.
The "Kitbashing" Route: Surgery for Plastic
Most people start here. Kitbashing is basically the "Frankenstein’s Monster" approach to toy making. You take the head of one figure, the torso of another, and the limbs of a third. It sounds easy until you realize that every toy company uses different neck peg sizes.
Have you ever tried to put a Marvel Legends head on a McFarlane body? It’s a nightmare. McFarlane Toys usually scales at 7 inches, while Marvel Legends sticks to the 6-inch (1:12) scale. They look ridiculous together.
The first step is the "boil and pop." You drop your donor figures into a mug of near-boiling water for about 90 seconds. The plastic softens. The joints become pliable. You pop the limbs out of the sockets. It’s satisfyingly gross. Once you have your "parts pile," the real work begins. You’ll likely need a Dremel to drill out neck holes or sand down waist pegs.
Professional customizers like Glenn Webb (rest in peace to a legend) paved the way for this community, showing that with enough Milliput—a two-part epoxy putty—you can sculpt over existing joints to create entirely new textures. If you want a character with a tactical vest, you don't buy a vest; you sculpt it onto a generic torso. It takes forever. Your fingers will cramp. But the result is a one-of-a-kind piece that actually has weight and "shelf presence."
The Digital Revolution: 3D Printing Your Dreams
If kitbashing is surgery, 3D printing is sorcery. This is the gold standard for how to create your own action figure in 2026.
Don't buy a filament printer for this. Just don't. FDM (Fused Deposition Modeling) printers are great for helmets or flower pots, but the layer lines will ruin a 6-inch figure. You need a Resin (SLA) printer. Something like an Elegoo Mars or an Anycubic Photon. These machines use UV light to cure liquid resin into incredibly sharp details. We’re talking individual rivets on armor or the texture of a cape.
But here is the catch that most "how-to" guides skip over: the engineering of joints.
- Ball joints: They need a specific amount of friction. Too loose, and your figure flops over. Too tight, and the resin snaps.
- Hinges: You have to account for "clearance." If you print a joint with zero gap, the resin will fuse together, and you'll have a statue, not an action figure.
- Shrinkage: Resin shrinks by about 1-3% as it cures. If you print a head and a body separately at different times, they might not fit.
You'll spend hours in software like Blender or ZBrush. If you aren't a sculptor, sites like MyMiniFactory or Patreon have "digital toy" creators like Printomancer or SkullForge who sell pre-supported files. You download the "blanks," add your custom details, and hit print.
Painting Without Ruining Everything
You've got your figure. It’s gray. It looks cool, but it’s lifeless. Now you have to paint it, and this is where most projects die.
If you use cheap craft store acrylics, your figure will look like it was dipped in melted crayons. The paint is too thick. It fills in all those beautiful details you worked so hard on. You need hobby paints—brands like Vallejo, Citadel, or Army Painter. These have high pigment density and go on thin.
The secret? Thin your paints with water. "Two thin coats" is the mantra of the hobby world.
Also, paint rub is the enemy. When you move an elbow joint, the plastic rubs against plastic. If there’s paint there, it will flake off instantly. Professional customizers "sand the joints" before painting. You shave off a fraction of a millimeter of material so that when the joint moves, the painted surfaces never actually touch. It’s a tedious process of sanding, testing, sanding again, and finally priming.
Don't forget the sealer. A matte varnish like Testors Dullcote is the industry favorite because it kills that "plastic" shine and makes the figure look like a high-end collectible from Hot Toys or NECA.
Soft Goods and Tiny Tailoring
Lately, there’s a huge trend toward "soft goods." Look at the Mezco One:12 Collective line. They use real fabric tailored to 6-inch scales.
Trying to sew a cape for a 6-inch figure on a standard sewing machine is like trying to perform heart surgery with a chainsaw. Most customizers use fabric glue or "HeatnBond" tape. If you want that dramatic "wind-blown" look, you have to sandwich a thin craft wire into the hem of the cape. This is called a wired cape, and it’s a game changer for photography.
The Logistics of Production
Maybe you don't just want one. Maybe you want to sell them.
This changes the game from a hobby to a business. To how to create your own action figure for a market, you’re looking at resin casting or overseas production. Resin casting involves making a silicone mold of your original sculpt and pouring liquid plastic into it. It’s messy, smells like a chemical factory, and requires a pressure pot to get the air bubbles out.
If you're thinking bigger—like a Kickstarter—you're looking at "steel molds." This is where the big boys play. Companies like Longshore in Hong Kong handle production for many independent toy lines. You’ll need a "control art" sheet showing the figure from the front, side, and back, along with a "Pantone" color guide. Expect to pay $5,000 to $15,000 just for the molds.
It’s a massive investment. But for a successful indie line like Marauder Task Force or Spero’s Animal Warriors of the Kingdom, it’s how they turned a hobby into a full-time career.
Common Pitfalls (What They Don't Tell You)
Let's talk about the "uncanny valley."
When people try to 3D scan their own faces to put on a figure, it usually looks terrifying. The skin looks like wax. The eyes are lifeless. To make a custom figure look "real," you actually have to exaggerate certain features. Human proportions don't always look good at six inches tall. We call this "heroic scale." You might need to make the head slightly smaller and the shoulders slightly broader to make the figure "pop" on a shelf.
Another thing: durability. 3D printed resin is brittle. If you drop a printed figure on a hardwood floor, it will shatter like glass. There are "tough" resins—like Siraya Tech Blu—that you can mix with standard resin to give it some flex. It’s like a mad scientist experiment in your garage.
Moving Forward With Your Project
If you're serious about this, don't try to build the perfect figure on day one. Start by customizing a cheap "fodder" figure you found at a flea market.
Step 1: The Concept. Draw it out. Don't just wing it. Decide if you’re going 1:12 (6-inch) or 1:18 (4-inch).
Step 2: The Base. Pick a figure that already has the articulation you want. If your character wears boots, find a base figure that already has boots. It saves hours of sculpting.

Step 3: Tools of the Trade. Get a set of stainless steel sculpting tools, a variety of sandpaper grits (400 to 2000), and a high-quality primer. Tamiya Grey Surface Primer is a gold standard for a reason. It sticks to anything and shows you every flaw in your sculpt before you start painting.
Step 4: Practice the Face. The eyes make or break the figure. Use a "000" size brush. Use a tiny dot of off-white (never pure white) for the eyeball and a toothpick to drop the pupil. If the eyes are straight, the figure is a success. If they're "derpy," nothing else matters.
Creating toys is a weird, obsessive, frustrating, and incredibly rewarding hobby. You'll spend three hours painting a belt buckle. You'll accidentally glue your fingers together with Cyanoacrylate (Super Glue). But when you finally click that last joint into place and stand your creation on the shelf next to the mass-produced stuff, you’ll realize yours is better. Because it’s exactly what you wanted.
Go find a donor figure. Get the water boiling. Start there.
