What is kitbashing and why is it so popular

At its core, kitbashing is a creative process of synthesis. It involves dissecting existing toys, models, or any plastic items and reassembling the parts, or ‘kits’, in a new configuration. This ‘bashing together’ of components allows you to create figures, vehicles, or dioramas that are entirely unique. The practice has roots in the scale modeling community, where hobbyists would use parts from different airplane or tank kits to create historically accurate or fictional variants. Today, the term has been enthusiastically adopted by action figure collectors. The primary driver of its modern popularity is the desire for personalization. Mass-produced toy lines can’t possibly cater to every fan’s specific desire, whether it’s a comic-accurate costume that was never released or a brand new character of their own invention. Kitbashing empowers the collector to become the creator. Another significant factor is the sense of community. Artists and hobbyists share their work-in-progress shots and finished customs on social media, creating a constant stream of inspiration and a supportive network for feedback and advice. This shared passion transforms a solitary act of creation into a collective celebration of ingenuity. It is a deeply rewarding hobby that combines the thrill of the hunt for parts with the satisfaction of hands-on artistic expression, resulting in a tangible piece of art that is truly your own.

Assembling your essential toolkit

Before you can start combining parts, you need the right tools to take them apart and put them back together. Building a solid kitbashing toolkit doesn’t require a massive investment, but having a few key items will make the process smoother and safer. The single most important tool is a high-quality hobby knife, often called a craft knife. This will be your primary instrument for cutting, trimming, and shaping plastic. Always use a sharp blade for clean cuts and work on a self-healing cutting mat to protect your surfaces. Next, you’ll need a set of files and fine-grit sandpaper to smooth out rough edges and shape sculpted parts. For adhesives, a tube of super glue with a precision tip is essential for bonding plastic parts together. For filling gaps or sculpting new details from scratch, a two-part epoxy putty like Milliput or Apoxie Sculpt is the industry standard. This material air-dries hard and can be sanded, drilled, and painted. To disassemble figures without breaking them, a hairdryer or a cup of hot water is invaluable. Heating the plastic softens it, allowing you to pop joints apart safely. A small set of pliers and wire cutters will also prove useful for removing stubborn pins or modifying internal components. Finally, always prioritize safety. Wear safety glasses to protect your eyes from flying plastic shards or stray knife slips. Working in a well-ventilated area is also crucial, especially when you move on to painting and sealing your creations.

The art of selecting your base and fodder

In the world of kitbashing, you will frequently hear the terms ‘base body’ and ‘fodder’. A base body is the primary figure you will build your custom upon. It should ideally have the right scale, articulation, and general silhouette for your intended character. Fodder refers to all the other figures and parts you will harvest to add to your base body. The art of selection is a skill in itself. When choosing a base, consider popular lines like Hasbro’s Marvel Legends or Star Wars The Black Series. These 1/12 scale lines are known for their extensive character rosters and relatively consistent joint systems, making part-swapping more straightforward. For a bulkier character, you might look at a McFarlane Toys figure or even a wrestling figure. The key is to look past the current character and see the potential of the underlying sculpt. Fodder can come from anywhere. That clearance aisle action figure with a cool-looking helmet, a broken toy from a thrift store with the perfect set of boots, or even household plastic items can all be part of your ‘fodder bin’. Building a healthy collection of spare parts is one of the most exciting parts of the hobby. It’s a treasure hunt where you are constantly evaluating every toy you see for its potential. When you are just starting, it’s wise to practice on inexpensive or damaged figures. This allows you to learn how different plastics react to cutting and gluing without the fear of ruining a valuable collectible. Over time, you’ll develop an eye for what parts will work well together, seeing the hidden potential in every piece of plastic.

The digital frontier 3D printing custom parts

While traditional kitbashing relies on sourcing parts from existing kits, the modern customizer has a powerful new tool at their disposal; 3D printing. This technology has revolutionized the hobby, moving the ceiling for creativity and detail to unprecedented heights. No longer are you limited to the parts you can find; if you can imagine it, there’s a good chance you can print it. For toy customizing, resin printers are typically favored over their filament-based FDM counterparts. Resin printers use UV light to cure liquid resin layer by layer, resulting in incredibly smooth surfaces and fine details that are perfect for things like character heads, intricate armor pieces, and custom weapons. The accessibility of entry-level resin printers has put this power into the hands of home hobbyists. Beyond owning a printer, there is a massive online ecosystem supporting this trend. Digital artists create and sell 3D files, or STLs, for custom parts on marketplaces and social media platforms. You can find everything from hyper-realistic unmasked heads of your favorite heroes to complete armor kits designed to fit specific base bodies. This means even without any 3D modeling skills, you can access a library of parts that would have been impossible to create by hand just a few years ago. Integrating 3D printed parts requires a bit of learning, such as properly cleaning and curing the resin, but the results are well worth the effort. It represents a a fantastic synergy between digital artistry and hands-on craftsmanship.

Painting and finishing techniques for a professional look

A great assembly of parts can be let down by a poor paint job. This stage is what truly unifies the different components and brings your custom figure to life. Achieving a professional, factory-like finish is a matter of patience and proper technique. The first and most crucial step is priming. A thin coat of primer, applied with a spray can or an airbrush, creates a uniform surface for your paints to adhere to. It covers up the different colors of the plastic parts and ensures your paint job will be durable. When it comes to painting, acrylic paints are the go-to choice for most customizers. Brands like Citadel, Vallejo, or Tamiya offer a wide range of colors designed for miniature painting. It is always better to apply multiple thin coats of paint rather than one thick one. This preserves the underlying sculptural details and results in a much smoother finish. To make your figure’s details pop, learn techniques like applying a ‘wash’. A wash is a very thin, dark paint that is applied over a base coat. It naturally settles into the recesses and panel lines, creating realistic shadows and depth. The opposite technique, ‘dry brushing’, involves using an almost-dry brush with a lighter color to gently catch the raised edges of a sculpt, creating highlights. Finally, once you are happy with your paint job, you must seal it. A matte or satin clear coat sealant will protect your work from chipping and handling, and it also helps to knock down any unwanted shine, giving the figure a more realistic appearance.

Bringing it all together a step-by-step project guide

Let’s make the process tangible with a hypothetical project; creating a custom post-apocalyptic scavenger. First is the concept and parts-gathering phase. We decide on a Marvel Legends figure with a lean build as our base body. From our fodder bin, we pull a gas mask from an old military figure, some pouches from a tactical vest, and a weathered rifle from a different toy line. We also find a 3D printed file for a tattered cloak online and print it out. The next step is assembly. We use hot water to soften the base figure’s joints and pop off the original head and hands. The new gas mask head is fitted to the neck peg, perhaps needing a small amount of epoxy putty to create a snug fit. We carefully glue the pouches onto the figure’s torso and belt, creating a unique loadout. The tattered cloak is draped over the shoulders and glued in place. Now, with all the parts combined, the figure looks like a mishmash of colors and plastics. This is where paint unifies everything. We apply a full coat of grey spray primer. Once dry, we begin base coating. We paint the pants a dark brown, the jacket a dusty olive green, and the metallic parts with a gunmetal color. After the base coats are dry, we apply a dark brown wash over the entire figure, letting it sink into the folds of the clothing and the details of the rifle. Once the wash is dry, we use a light tan to dry brush the edges of the cloak and pants, simulating wear and dust. A final spray of matte sealant protects our hard work and eliminates any unnatural shine. The result is a completely new, one-of-a-kind character, born from imagination and a collection of disparate parts.

In conclusion, the journey of kitbashing is one of immense creativity and reward. It transforms the passive act of collecting into an active, engaging artistic pursuit. We have walked through the entire process, from understanding the core concept to assembling a toolkit filled with essential items. We explored the thrill of hunting for the perfect base body and fodder parts, and we saw how the digital revolution of 3D printing has opened up a universe of new possibilities for customizers. Furthermore, we demystified the painting and finishing process, breaking it down into achievable steps like priming, washing, and sealing that can elevate your project from a simple toy to a piece of art. The system is straightforward; plan, disassemble, combine, sculpt, paint, and seal. Each step builds upon the last, culminating in a figure that is uniquely yours. The beauty of this hobby is its scalability. You can start with a simple head swap or dive deep into a complex project involving sculpting and 3D printed parts. The most important thing is to begin. So take a look at your collection, pick out a few candidates, and take that first step. Create the characters you have always wanted to see and share your work with the vibrant community. Your next masterpiece is just waiting to be bashed together.
