Additive manufacturing offers great design and engineering practice for professionals and miniature-making enthusiasts, who will be thrilled to see the designs of their imaginations come to life in a 3D printer.

All 3D printing technologies use a process called additive manufacturing. 3D printers create three-dimensional parts from computer-aided design (CAD) models by successively adding material layer by layer until a physical part is created. Prop makers, game designers, and hobbyists can use the following 3D printer technologies to create various props, miniatures, and figurines.

Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used form of 3D printing at the consumer level, fueled by the emergence of hobbyist 3D printers. FDM 3D printers build parts by melting and extruding thermoplastic filament, which a printer nozzle deposits layer by layer in the build area.

Compared to other 3D printing processes, FDM creates larger and more visible layer lines, leading to less-detailed end products. An FDM 3D printer is good for cheaply and quickly 3D printing miniatures for applications where fine surface details are less important.

Depending on your model, post-processing for FDM printing might only require support removal. However, complex figurines printed with an FDM printer require extra support structures, which can be difficult to remove and require sanding to get support marks off finished miniatures.

FDM printers are the least expensive option. A low-end hobbyist desktop FDM printer can cost less than $500, while a more professional FDM printer for figurines can cost on average from $2,000-4,000.

A side-by-side comparison on FDM vs SLA 3D printed parts.

Stereolithography (SLA) printers are the most versatile and precise desktop 3D printers on the market. SLA printer technology uses vat photopolymerization, or resin printing, to cure liquid resin into hardened plastic using a laser. Resin 3D printing produces finely detailed miniatures and figurines with high surface quality using a range of advanced materials.

Resin 3D printers bring high-resolution for miniatures, figurines, and models. Even the smallest prints have a high level of detail.

A printed figurine from an SLA printer will require a medium-length post-curing process, but automated post-curing options are available. Support structures from SLA printers, especially from low force stereolithography (LFS) printers like the Formlabs Form 3 and Form 3L, are easy to remove.

SLA 3D printers also offer a wide range of materials, empowering applications outside of traditional 3D printing like silicone molding, pewter casting, or lost-wax casting.

A high-resolution quality desktop SLA 3D printer from Formlabs for miniatures and figurines price starts at $3,499, while large-format SLA 3D printers start at $10,999.

"For bigger, less detailed things or as part of mold-making workflows, I use FDM 3D printers. I mostly use Formlabs [SLA] 3D printers to print final parts, because you get such a nice finish."

Selective laser sintering (SLS) uses a high-powered laser to fuse small particles of polymer powder. As the unfused powder supports the part during printing, there's no need for dedicated support structures. This makes powder 3D printing ideal for intricate models and complex geometries, including interior features, undercuts, thin walls, and negative features.

SLS 3D printing is ideal for intricate models and complex geometries. Part printed on a Fuse 1 SLS 3D printer.

SLS parts have a slightly grainy surface finish, but almost no visible layer lines. The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production.

Because SLS printers are industrial machines, the entry price used to be higher, starting at around $100,000 and making it inaccessible for many businesses. However, Formlabs has recently introduced the Formlabs Fuse 1 to bridge this gap with the first benchtop industrial SLS 3D printer that offers high quality at a fraction of the cost of traditional industrial SLS systems, starting at $18,499.

Binder jetting is similar to SLS printing, but uses a binding agent to bond the powder material instead of heat. In model making, binder jetting is most commonly used for creating full-color figurines out of sandstone material.

Just like SLS, binder jetting requires no support structures, as the surrounding powder provides the necessary model support. However, parts that come off a binder jetting printer are very brittle and have high porosity. This means that the process is not ideal for complex designs, as the parts may fracture in the post-processing due to the brittleness of the material.

Binder jetting 3D printers are expensive industrial machines, with prices ranging from $30,000 to $100,000+.

The level of detail and precision needed for printing miniatures can be challenging. Beyond the printing process, post-processing will have a high impact on the final miniature. Here are some tips on how to better 3D print and prepare miniatures.

Two major factors impact the quality of your 3D prints: layer lines and support structures.

The thicker the layers you use for your 3D printed figure, the more visible your layer lines will be. Thick layer lines create a "staircase" effect on a flat or slanted surface or cause round surfaces to appear "pixelated." Smaller layer thickness will lead to higher surface quality and more polished prints.

FDM printing tends to use thicker layers and the layer lines are more visible even at the same layer height due to the way the parts are formed. SLA printers can print at a variety of layer thicknesses, including incredibly thin 25-micron layers, depending on the desired print quality, which makes it the ideal choice for showcasing the best details. SLS and binder jetting printers print at around 100-110 micron layers, but the layer lines are mostly invisible on final parts.

In FDM and SLA printers, 3D prints include support structures to scaffold the part during the print process. You will need to remove these support structures, which can be difficult for FDM prints and fairly easy for SLA prints (depending on part orientation). A more complicated support removal will leave marks on the finished product, which you must sand and polish for high-quality finishes.

Your models will not be complete without the perfect finish. After printing, post-processing the miniatures with priming and painting will give a final flawless touch and the customization to make them truly unique.

Priming a 3D printed miniature before painting.

You can finish a 3D printed figurine in whatever way supports the end goal of your 3D print. Many models look great straight out of the printer, but you can enhance your miniatures by painting them.

Before you paint, remove all support structures from your printed figurines, and then sand the figurines to eliminate support-structure marks. The amount of sanding and polishing will depend on the object's finish. For FDM prints, you may have to do some extra sanding to reduce the "staircase" effect of layer lines, while SLA prints should have a smooth surface right away.

After you sand your 3D miniature, we recommend applying a primer. Choosing the right primer will help your 3D printed miniature achieve a professional-grade finish.

For detailed hand painting of your 3D printed miniature, acrylic paint is a versatile option. Acrylic paint usually binds well to plastic, but always check that the paint you have selected lists "plastic" or "multisurface" functionality, and always prime before you paint.

Spray paint, when applied correctly, can also give your custom miniature a smooth, glossy, and consistent finish. Your spray paint finish can approach professional quality if you apply a good primer and a thick undercoat for color consistency. Always finish with a blemish-resistant topcoat.

3D printing always starts with a digital model. You can download a free or paid miniature model, design the model yourself, or even scan an existing object and turn it into a 3D file.

If you are at the beginning of your 3D printing journey, downloading premade designs can make printing easy. Huge online communities exist around gaming miniatures, such as Dungeons & Dragons figurines. Checking communities like Pinshape, MyMiniFactory, Cults, or Thingiverse is a great way to find free 3D miniature model designs for your own prints.

The right 3D modeling software will help you design your own custom miniatures that are ready for 3D printing. If you are creating miniatures, you need detailed design capabilities. CAD software that specializes in video game design or animation often provides the granular tools necessary for creating realistic miniatures.

For example, ZBrush is a digital sculpting tool that combines multiple artistic techniques to create high-resolution models. Users mainly design for movies, games, and animations on ZBrush, making it ideal for realistic figurines. You can learn more about how ZBrush is used for digital sculpting, modeling, and rapid visualization in this webinar.

A custom 3D print does not need to be based on a completely original digital design. Instead, you can also 3D scan an existing object. There are many scanning options available, from low-cost depth-sensing cameras and photogrammetry to high-definition professional scanners.

Before 3D printing a part, you'll often need to adapt, optimize, and finalize 3D scans. With Meshmixer, it's not only possible to optimize a triangle mesh but also to resculpt entire sections, stylize the model, or add useful features to it.

Whether you are a professional sculptor, a model maker, an enthusiastic hobbyist, or a gamer, SLA 3D printing is an ideal tool to bring hyper-realistic digital models to life in a matter of hours, right on your desktop.
