Gaming miniatures are available in a variety of materials,
and each has its positives and negatives.
There are times when you have no choice as to what material you end up
with, because you may only be able to find a particular mini from one
manufacturer, and in one kind of material.
Let’s look at how these different materials stack up.
LEAD (lead-based alloys)
The original metal used for gaming minis, some still swear
by it. The big advantage of lead is that
it is easy to cast. Lead melts at a low
temperature, and sets quickly when cooled to room temperature. These qualities mean that not much is
required to cast. A sculptor could make
some simple molds and start producing lead minis in his or her garage. This is why there are small outfits still working
to produce small batches of minis, often of specialized subjects.
But lead, which has traditionally been cheap, has risen in
price, making it harder for small operators to work cheaply. But an even more pernicious problem is with
its toxicity, both the reality and the public perception. Many producers went away from lead to
accommodate local laws or to avoid concerns over toxic exposure to children.
As a modeling material, lead leaves a lot to be desired. It is extremely soft, and bends easily. That means that swords, spears and other
protrusions on a mini will frequently become bent out of shape, requiring you
to bend them back. Butit is also
brittle, so that frequent bending may cause it to break. Most old gamers have more than one old lead mini
missing a sword or other feature.
Repairing lead minis is also quite difficult. The metal deforms, so simply pinning back in
place will leave an uneven appearance.
The soft lead is bad for filing and sanding, and pegs and holes for
multipart figures can become bent and hard to fit together.
All minis will be dropped, knocked over or experience other
table wear. Lead minis do not weather
these pitfalls well at all. When a
painted lead mini takes a hit, it often leaves a dent, chipping the paint and
obscuring detail. Anyone with a
collection of painted lead minis likely has a few with grey, flattened noses
from falling on their faces.
These fellows have seen better days. |
All in all, there is a reason that companies that have the
choice do not work in lead anymore.
PEWTER
Lead free pewter is the industry standard for gaming
miniatures today. It is a much harder
metal, and holds details well because of this.
It resists deforming and chipping when subjected to abuse, and can be
easily filed and drilled for pinning, although it can be difficult to cut, as
clippers will deform the metal, requiring the use of saws, which dull quickly
on the hard metal.
For many gamers and modelers, pewter is the only acceptable
material. Many wargamers in particular
simply can’t abide to use minis without the heft of real metal. For durability and versatility, pewter is
tough to beat.

It is not as easy to cast in as softer, lead-based alloys,
but still requires less equipment than plastic minis. However pewter is pricier than lead alloys,
and that price is steadily increasing, leading many manufacturers to look
towards alternatives.
PLASTIC (Polystyrene)
This is the type of plastic that model cars and airplanes
are made from. The majority of minis
that come on polystyrene are in the form of multipart kits. Parts for the minis are molded onto sprues
(those plastic frames that you have to clip the parts off of,) and are then
assembled how you prefer, giving a greater degree of individualization.

Polystyrene accepts wonderful levels of detail, and does not
dent or chip easily. The material is
certainly the best for conversion work, as it drills smoothly, sands, shaves
and carves easily, and if glued together with polystyrene solvent, bonds
remarkably strong. It is also far
cheaper to make per miniature than either pewter or lead.
However, polystyrene is brittle, and will break if subjected
to force. There is also a practical
limit on how narrow or thin a mini can be made.
Not only do small parts tend to develop molding errors such as flashing
(the thin sheets of extra plastic that cling to the min, leftover from the
molding process,) but such small parts become fragile timebombs, just waiting
for the slightest nudge to snap off.
In addition, such minis are not simple to make. Working with polystyrene involves precision
injection molds, something to which most garage startups do not have
access. Because of the high startup
price of this equipment, traditionally only the largest companies have been
able to produce polystyrene minis.
This situation is changing somewhat, as a few newer
companies are investing in plastics and producing their own multi-part
kits. Some will even offer to take your
old sprues from their or other manufacturers to recycle, offering a discount in
exchange.
Polystyrene is a great material to work with for converters
or beginning modeleres alike, as long as you can find a producer who offers the
particular kind of mini you need.
PLASTIC (Polyvinyl chloride)
PVC comes in a wide variety of textures and qualities, and
for many gamers, it is anathema, the forbidden plastic that dare not sully
their tables. But PVC has some traits
that other materials can’t match.
One is that they are available in many colors, worked into
the plastic itself. This includes clear
plastics, allowing for all kinds of funky effects. The kinds of PVC that are used in miniatures
such as Heroclix, and WotC’s Star Wars and D&D minis is soft and pliable,
often quite rubbery in feel.

That pliancy makes them quite resilient, as minis will bend
rather than break when subjected to force.
Because of this, minis can be made with very narrow features, such as
swords, skinny arms, and whatnot. Such
pieces will not break or snap off, so the sculptors can make more fragile
appearing minis.
But that same quality can make them hard to work with. The rubbery types of PVC are difficult to
shave or trim mold lines off of.
Drilling for pinning can also be somewhat troublesome, especially on
minis with very skinny limbs.
In addition, those swords and other accouterments will tend
to droop, or become permanently bent in shipping. Most sites will say that simply heating the
pieces in hot water and then rebending them and setting them in cold water will
reverse this, but your mileage may vary.
But these are far and away the cheapest minis
available. Even if you are paying
retail, you will get more for your money with PVC. Normally, those savings are offset by blind,
random packaging, but Reaper Miniatures has a line of unpainted PVC minis
called Bones that use the same sculpts as their pewter lines, but at a fraction
of the cost.
Just like polystyrene, it takes a major manufacturer with
the right equipment to produce such minis, so you won’t have as wide a
selection.
If you can stand ‘bendy’ minis, and can reliably find pieces
that fit what you want, PVC is probably the way to go.
RESIN
I’m going to level with you.
I don’t own a single resin mini, and have never worked with any. I can’t speak as to how well they paint up
(supposedly great,) or how resilient they are (damn near indestructible in some
cases,) or how they are for converting (I’ve heard they’re terrible, really
brittle and hard to cut or drill.)
What I can tell you is the reason I don’t have any: they are
expensive. Resin minis can be made by
small outfits, and are usually found in specialized lines such as licensed
properties or conversion kit parts.
I will say that supposedly new forms of resin have come to
light, and companies like Mantic and Games Workshop (please hold all booing and
hissing,) are moving towards more resin, with GW in particular pushing it heavily
with their new ‘Citadel Finecast’ products.
And that’s all I have to say about Resin.
CONCLUSIONS
So there are my takes on the various materials you will find
in the world of minis today. I will be
working with nearly all of these on this blog and will go into more specifics
on how best to work with each.
I hope this has been informative.
