When you buy terrain, it is easy to only see the finished product on the table.
A painted wall section. A ruined corner. A set of industrial details that brings a battlefield to life.
But before any of that reaches your gaming table, a lot happens behind the scenes.
At Build Your Battlefield, our terrain is designed and produced in-house. That means the process does not start in a factory somewhere far away; it starts here, in the workshop, with a design, a master model, a mould, and a resin pour.
In this post, we wanted to show you exactly how we cast our resin terrain, why we use this process, and what it means for the quality of the final product.
Why We Use Resin Casting for Tabletop Terrain
Our goal has always been simple: create modular tabletop terrain that looks great, feels solid, and can be produced consistently enough to build full battlefields.
For that, resin casting is the best fit.
Casting allows us to capture a lot of detail while also producing terrain pieces efficiently. Instead of 3D printing every single wall that goes into a set, we create high-quality master pieces first, then use silicone moulds to reproduce them in polyurethane resin.
That gives us the best of both worlds:
- sharp detail
- durable parts
- consistent quality
- efficient small-batch production
- the ability to produce full wargaming terrain sets
For a modular system like Build Your Battlefield, that matters. A sector is not just one or two decorative pieces — it is a full set of terrain components designed to work together and give you the freedom to build your table your way.
Step 1: Designing the Terrain
Every cast starts with a design.
Before we make any moulds or pour any resin, each terrain piece is first designed digitally. During that stage, we are not only thinking about how the part should look, but also how it should function within the Build Your Battlefield system.
That means asking questions like:
- Does it fit the modular wall system?
- Is it strong enough for regular tabletop use?
- Will the detail still read clearly once painted?
- Can it be cast cleanly and consistently?
- Will cleanup be minimal?
Because our terrain is meant to be practical as well as good-looking, every piece is designed with both tabletop use and production in mind.
The end result is a terrain element that is not just visually interesting, but also made to work as part of a modular battlefield.
Step 2: Creating the Master
Once the design is ready, we produce a master copy.
This master is 3D printed at high resolution so it captures all the detail we want in the final terrain piece. Cracks, damage, surface texture, panel lines, industrial details, stonework — all of that starts here.
After printing, the master is cleaned and cured, and then inspected carefully.
This is an important part of the process, because the mould will copy the master exactly. If there is a flaw on the master, there is a good chance it will show up in every cast made from it.
So before we move on, we make sure the master is good enough to represent the final product properly.
Step 3: Making the Silicone Mould
With the master ready, the next step is making the mould.
The master is placed inside a mould box, and then we pour silicone around it. Once the silicone cures, the master is removed, leaving behind a negative impression of the piece.
That mould is what allows us to reproduce the terrain part again and again.
We use silicone moulds because they are flexible, highly detailed, and ideal for resin casting. They capture small details very well, while also making it possible to remove cured resin parts without damaging them.
For many pieces, we do not just make a mould for one part at a time. We often create moulds that hold multiple terrain elements, which makes production more efficient and helps us produce full terrain sets more reliably.
The mould layout itself matters too. Pour points, orientation, and spacing all affect how well a part casts. So that side of the process is carefully considered as well.
The aim is always the same: clean casts, strong detail, and minimal waste.
Step 4: Mixing and Pouring the Resin
Once the mould is ready, it is time to cast the actual terrain.
We use a polyurethane casting resin, which starts as two separate liquid components. These are measured out, mixed together, and then poured into the mould.
This part is time-sensitive. Once the resin is mixed, it begins to react and cure, so preparation matters. Everything has to be ready before pouring starts.
The liquid resin flows into the mould and fills all the detail that was captured from the original master. This is where the terrain piece truly starts to take shape.
It is always satisfying to see this stage happen, because a mould that looked empty a moment before is now becoming a finished wall section, detail piece, or modular terrain component.
Step 5: Demoulding the Cast
After the resin has cured, the cast can be removed from the mould.
This is the moment where the terrain piece actually emerges as a real product.
The cured resin is solid, durable, and ready for the next stage. Each piece is removed carefully and checked for quality. If there is any small amount of excess material from the pour point or mould line, it is cleaned up.
Not every cast makes the cut. If a part is not good enough, it does not get packed.
That quality control matters, especially when you are building full terrain systems. Every part needs to fit, function, and match the standard we want Build Your Battlefield to stand for.
Why Hand-Cast Terrain Still Matters
There is something different about hand-cast resin terrain.
It is not just a production method — it is part of the identity of the product.
At Build Your Battlefield, the terrain is not mass-produced in an anonymous way. It is designed, tested, moulded, cast, and improved as part of an ongoing hands-on process.
That gives us more control.
If we want to refine a wall, improve a mould, or develop a completely new theme, we can do that directly. We are not waiting on some huge outside system to change course. We can design, test, adapt, and keep improving.
That is one of the biggest strengths of producing tabletop terrain in-house.
It means Build Your Battlefield is not just a brand name on a box. It is a system we actively work on, build out, and refine.
The Benefits of Resin Terrain for Wargaming
For wargaming terrain, resin has a lot going for it.
It captures detail far better than many mass-production alternatives, while still being durable enough for regular gaming use. It is also easy to work with if you want to customise, clean up, prime, or paint the pieces.
That makes it a strong choice for hobbyists who want terrain that looks good straight away, but also rewards painting and personalisation.
For us, resin is especially useful because our terrain is modular. The system is meant to be used, rearranged, expanded, and combined into new layouts. That means the parts need to be strong, practical, and consistent, not just decorative.
From Workshop to Battlefield
By the time one of our terrain pieces reaches your table, it has gone through several stages:
- it was digitally designed
- a master was produced
- a silicone mould was made
- resin was mixed and poured
- the cast was demoulded, cleaned, and checked
Only then is it ready to become part of your battlefield.
That full process is a big part of what Build Your Battlefield is about.
We are not interested in pumping out generic scenery. We want to build terrain systems that give players real flexibility, real quality, and a battlefield that feels like their own.
That is why we cast our terrain the way we do.
Because the goal is not just to make terrain.
The goal is to help you build your battlefield.
